I am trying to put 25 Buttons inside a Panel in VB.Net 2015 Classic Form Like the Picture but it is not working . could you please help... bellow my code
Dim i As Integer
For i = 1 To 25
newButton = New Windows.Forms.Button
newButton.AutoSize = True
newButton.Name = "btnButton" & i
newButton.Text = "Button " & i
newButton.Top = i * 5
newButton.Left = i * 25
newButton.Size = New Size(95, 70)
AddHandler newButton.Click, AddressOf ButtonClicked
Panel1.Controls.Add(newButton)
Next
Your code is creating the buttons, and the problem is that they are not arranged properly so what you need to do is arrange them in rows and columns. here i help you to do this;
Here this snippet will tell you how to arrange them in 5 columns and n rows:
Dim x As Integer = 5 ' x co-ordinate of the point
Dim y As Integer = 5 ' y co-ordinate of the point
For i = 1 To 25
If i Mod 5 = 0 Then ' For starting next row after column
y += 100 ' 100 is not mandatory change as per size of button
x = 0
Else
x += 100 ' 100 is not mandatory change as per size of button
End If
Dim p As Point = New Point(x, y)
Dim newButton = New Windows.Forms.Button
newButton.Location = p
//do the rest of formatting here
Panel1.Controls.Add(newButton)

I've been stuck in this for two hours now. I googled for the answer a lot, and still can't figure out what's wrong with my program.
I have a TableLayoutPanel1 in a form2. This is the code in which I create labels, a list and then add all of those labels to the TableLayOutPanel1:
Public Class Form2
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
Dim lbl0, lbl1, lbl11, lbl2, lbl22, lbl3, lbl33, lbl4, lbl44, lbl5, lbl55, lbl6, lbl66, lbl7, lbl77 As New Label
lbl0.Text = "ACCESORIOS"
lbl0.Font = New System.Drawing.Font("MS Reference Sans Serif", 15.75, FontStyle.Bold)
lbl0.Location = New Point(110, 12)
lbl0.AutoSize = True
Me.Controls.Add(lbl0)
lbl1.Text = "Té 180°"
lbl11.Text = Te180
lbl2.Text = "Té 90° Empalme - Codo Triple"
If Global1 <> 0 Then
lbl22.Text = 0
Else
lbl22.Text = Global2 - 1
End If
lbl3.Text = "Soporte 90° T/T"
lbl33.Text = SoporteTT90
lbl4.Text = "Base para tubo de 1 1/2 - 3 agujeros"
lbl44.Text = Int(lbl11.Text) + Int(lbl22.Text) + (lbl33.Text)
lbl5.Text = "Base para tubo de 1 1/2 - 1 agujero"
lbl55.Text = 2
lbl6.Text = "Tapas para base de tubo de 1 1/2"
lbl66.Text = lbl44.Text
lbl7.Text = "Tornillos y Tarugos 5 x 50 y N°8 Ladrillo Hueco"
lbl7.Font = New System.Drawing.Font("MS Reference Sans Serif", 15.75, FontStyle.Bold)
lbl77.Text = (Int(lbl44.Text) + Int(lbl55.Text)) * 3
Dim labellist As New List(Of Label)()
labellist.Add(lbl1)
labellist.Add(lbl2)
labellist.Add(lbl3)
labellist.Add(lbl4)
labellist.Add(lbl5)
labellist.Add(lbl6)
labellist.Add(lbl7)
labellist.Add(lbl11)
labellist.Add(lbl22)
labellist.Add(lbl33)
labellist.Add(lbl44)
labellist.Add(lbl55)
labellist.Add(lbl66)
labellist.Add(lbl77)
Dim h = 0
For i = 0 To 1
For j = 0 To 6
Dim etiqueta As New Label
etiqueta.Text = labellist(h).Text
TableLayoutPanel1.Controls.Add(etiqueta, i, j)
h = h + 1
Next
Next
End Sub
End Class
The problem is that the the full label doesn't appear in the table.[enter image description here][1]
I have tried Autosizing the labels, the tablelayout. Nothing works. It's like there's an invisible line that doesn't let the text of the label get past a line in the table. Any help appreciated. Thanks.
The layout in form2. enter image description here
What happens when I make the font in the TLP 5pts. The whole label appears in two lines. enter image description here
Mainly, you create all those labels, store them in a list. Then all you use them for is to set the text on another new label you create to add to the controls collection.
Here is a shorter, simpler way to do all that with no extra list, and just one scratch label variable for the TLP set:
Dim texts = {"Te 180", "Te 90 - blah blah blah", "Soprte 90 T/T",
"Torillas y salsa", "Torillas y salsa y guacamole"}
Dim lbl As Label
For n As Int32 = 0 To texts.Length - 1
lbl = New Label
lbl.Text = texts(n)
' more important than autozise, probably:
lbl.Dock = DockStyle.Fill
' debug: to see the border for tweaking
lbl.BorderStyle = BorderStyle.FixedSingle
' add the one you created to the controls collection
tlp1.Controls.Add(lbl, 0, n)

I have a number of buttons between 5-20 and it's variable each time the form loads based on the user settings. I am trying to fit all these buttons on my form no matter what the size of the form is. The buttons are generated during runtime. I would like the first button to be 20 points from the top bar (at any size) and the rest of the buttons simply to fit in the form. This is what I have now but I have to maximize the form to view them all and also while I'm expanding the form the space between the buttons decreases and they overlap with each other whereas they should keep a relative distance. Any ideas?
Dim iButtonWidth, iButtonHeight, iVerticalSpace As Integer
If UserButtons.Count > 0 Then
iButtonHeight = Me.Size.Height - (Me.Size.Height * 0.85)
iButtonWidth = Me.Size.Width - (Me.Size.Width * 0.5)
iVerticalSpace = iButtonHeight / 3
For Each btn In UserButtons
btn.Size = New System.Drawing.Size(iButtonWidth, iButtonHeight)
btn.Location = New Point(20, 20 + btn.TabIndex * iVerticalSpace * 3)
Next
End If
Here's a quick example using the TableLayoutPanel to play with:
Public Class Form1
Private UserButtons As New List(Of Button)
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
Static R As New Random
Dim NumButtons As Integer = R.Next(5, 21) ' "a number of buttons between 5-20 and it's variable each time"
UserButtons.Clear()
For i As Integer = 1 To NumButtons
Dim btn As New Button()
btn.Text = i.ToString("00")
btn.Dock = DockStyle.Fill ' Optional: See how you like it with this on vs. off
UserButtons.Add(btn)
Next
DisplayButtons()
End Sub
Private Sub DisplayButtons()
TableLayoutPanel1.SuspendLayout()
TableLayoutPanel1.Controls.Clear()
TableLayoutPanel1.ColumnStyles.Clear()
TableLayoutPanel1.ColumnCount = 5 ' Fixed Number of Columns
For i As Integer = 1 To TableLayoutPanel1.ColumnCount
TableLayoutPanel1.ColumnStyles.Add(New ColumnStyle(SizeType.Percent, 911)) ' the size doesn't matter here, as long as they are all the same
Next
' Variable Number of Rows:
Dim RowsRequired As Integer = ((UserButtons.Count - 1) \ TableLayoutPanel1.ColumnCount) + 1 ' Integer Division
TableLayoutPanel1.RowStyles.Clear()
TableLayoutPanel1.RowCount = RowsRequired
For i As Integer = 1 To TableLayoutPanel1.RowCount
TableLayoutPanel1.RowStyles.Add(New RowStyle(SizeType.Percent, 911)) ' the size doesn't matter here, as long as they are all the same
Next
TableLayoutPanel1.Controls.AddRange(UserButtons.ToArray)
TableLayoutPanel1.ResumeLayout()
End Sub
End Class
First of all what kind of container are the buttons in? You should be able to set the container's AutoScroll property to true - then when controls within it spill out of the visible bounds you will get a scroll bar.
Then also what you could do is draw each button in more of a table with a certain number next to each other before dropping down to the next line (instead of just 1 button on each line). If that is an option that works for you then you could get more buttons within the visible space.
I happen to have an example to do the same thing with picture boxes (and text boxes under each picture box). Hope this helps:
Dim point As New Point(0, 0)
'create 11 picture and text boxes-you can make this number the number your user selects.
Dim box(11) As PictureBox
Dim text(11) As TextBox
Dim i As UInt16
For i = 0 To 11 'or whatever your number is
box(i) = New PictureBox
box(i).Width = 250 'your button width
box(i).Height = 170 'your button height
box(i).BorderStyle = BorderStyle.FixedSingle
box(i).Location = point
layoutsPanel.Controls.Add(box(i)) 'my container is a panel
text(i) = New TextBox
text(i).Height = 50
text(i).Width = 250
point.Y += box(i).Height
text(i).Location = (point)
layoutsPanel.Controls.Add(text(i))
point.Y -= box(i).Height 'reset Y for next picture box
'Put 4 picture boxes in a row, then move down to next row
If i Mod 4 = 3 Then
point.X = 0
point.Y += box(i).Height + text(i).Height + 4
Else
point.X += box(i).Width + 4
End If
Next
I am trying to make a function to create textboxes. I need to know if there is a way to replace the end of a string with the new number.
While x <= tbnumberofitems
Dim x As Integer = 0 ' looop count '
Dim y As Integer = 1 ' name count'
Dim label1name As String = "label"
Dim textbox1name As String = "textbox"
While x <= tbnumberofitems
y = y + 1
If x = 0 Then y = 1
Convert.ToString(y)
Dim label1 As New Label
label1.Name = label1name & y
'Code to create label box
Dim textbox1 As New TextBox
textbox1.Name = textbox1name & y
'code to create text box
x = x + 1
End While
This is what I currently have. What I need now is a way to make it where when the loop runs the next time, it changes the name to textbox2 and label2 on 3rd loop label 3 and textbox 3, etc. If that is not clear enough what I am trying to do is make it where the numberofitems, make it 5, creates 5 labels and 5 textboxes through the program.
Basicly Like this ..
For x as Integer = 1 to tbnumberofitems
'Code to create label
Dim lbl As New Label
lbl.Name = "label" & format(x)
lbl.Location = New Point(10, x*20)
Me.Controls.Add(lbl)
'Code to create textbox
Dim tb As New TextBox
tb.Name = "TextBox" & format(x)
tb.Location = New Point(100, x*20)
Me.Controls.Add(tb)

In VB.NET, I need to print multiple Images of bar codes by arranging them in tabular format. For now what I am doing is, Creating the bar codes and adding them in new picture box. These Picture boxes are added on a panel which I am creating on form at run time and print that panel (with picture boxes in 4x9 table).
But, when I need to print more that 36 bar codes, this idea doesn't work.
So, Please suggest me some improvements in my code or any other way to do this job.
I am sorry, here is the code for generating images and adding them to the panel..
''' Method for create bar code images with a loop and adding them to the panel by picture box...
Private Function GetBarcodeText(RowId As Guid)
Dim BarcodeValue As StringBuilder = New StringBuilder(96)
Dim temp As New StringBuilder
Dim data As String
Dim param = New SqlParameter()
Dim imageNo As Integer = 0
Dim colorValue As String = ""
Dim scaleValue As String = ""
'' Adding the panel on the form which is dynamically created
Me.Controls.Add(outputPanel)
'' Setting the Initial size for the panel
outputPanel.Size = New Point(794, 112)
outputPanel.Name = "outputPanel"
outputPanel.BackColor = Drawing.Color.White
param.ParameterName = "#RowId"
param.Value = RowId
param.SqlDbType = SqlDbType.UniqueIdentifier
' Get the particular row of data from database
dt = objStockProvider.GetBarcodeDetails(param)
' GET colour code
Dim color As String = dt.Rows(0)("COLOUR").ToString()
Dim countColors As Integer = 0
' Get the color code numbers
param.ParameterName = "#Dscale"
param.Value = dgvViewTickets.CurrentRow.Cells("SCALE").Value.ToString()
countColors = objStockProvider.CountColorCodes(param)
For i = 1 To countColors
For j As Integer = 1 + ((12 / countColors) * (i - 1)) To (12 / countColors) * i
If dt.Rows(0)("S" + j.ToString()) <> 0 Then
Dim totalTicketsForASize As Integer

For k As Integer = 1 To totalTicketsForASize
' Set Bar code value which has to create

' Create Barcode Image for given value
Dim image = GetBarcodeImage(BarcodeValue, colorValue, scaleValue)
If image IsNot Nothing Then
'' Create picture box to contain generated Image.
Dim pcbImage As New PictureBox
pcbImage.Width = W
pcbImage.Height = H
pcbImage.Image = image
pcbImage.Location = New Point(X, Y)
imageNo += 1
If imageNo Mod 4 = 0 Then
X = 15
Y += H
outputPanel.Height += H
Else
X += W
Y = Y
End If
pcbImage.Visible = True
'' Adding picture box to panel
outputPanel.Controls.Add(pcbImage)
End If
Next
End If
Next
color = color.Substring(color.IndexOf(",") + 1, color.Length - color.IndexOf(",") - 1)
Next
PrintGeneratedTickets()
End Function
Now, I am printing the panel by following method:
Private Sub PrintGeneratedTickets()
bmp = New Bitmap(outputPanel.DisplayRectangle.Width, outputPanel.DisplayRectangle.Height)
Dim G As Graphics = Graphics.FromImage(bmp)
G.DrawRectangle(Pens.White, New Rectangle(0, 0, Me.outputPanel.DisplayRectangle.Width, Me.outputPanel.DisplayRectangle.Height))
Dim Hdc As IntPtr = G.GetHdc()
SendMessage(outputPanel.Handle, WM_PRINT, Hdc, DrawingOptions.PRF_OWNED Or DrawingOptions.PRF_CHILDREN Or DrawingOptions.PRF_CLIENT Or DrawingOptions.PRF_NONCLIENT)
G.ReleaseHdc(Hdc)
pndocument.DocumentName = bmp.ToString()
Dim previewmode As New PrintPreviewDialog
previewmode.Document = pndocument
previewmode.WindowState = FormWindowState.Maximized
previewmode.PrintPreviewControl.Zoom = 1
pndocument.DefaultPageSettings.Margins.Top = 10
pndocument.DefaultPageSettings.Margins.Bottom = 30
pndocument.DefaultPageSettings.Margins.Left = 16
pndocument.DefaultPageSettings.Margins.Right = 16
pndocument.DefaultPageSettings.Landscape = False
' Set other properties.
previewmode.PrintPreviewControl.Columns = 4
previewmode.PrintPreviewControl.Rows = 9
previewmode.ShowDialog()
Dim file As String = DateTime.Now.ToString()
file = Path.GetFullPath("D:\Bar Codes\" + file.Replace("/", "-").Replace(":", ".") + ".bmp")
bmp.Save(file)
G.Dispose()
outputPanel.Controls.Clear()
End Sub
This code is working fine but what I need to do, is to fix the number of images (4x9) per page. But when I am trying to create more than it, that all are printing on a single page with compressed size.
Also when trying to re-run the code, It shows nothing in preview..
Some body please suggest the correction in code so that I can reprint the tickets and use paging for more than 36 images.
Well, Printing the Images on a panel was not a good idea.. I replaced the panel and created an array of images and used the print document directly and print after arranging images on it.
Thanks.
Guys I'm trying to dynamically create panels which are filled with seven radio buttons each.
I get the panels but they are only filled with 1 radio button each. What am I doing wrong here? QuestionQuantity is an Integer and is the variable that determines how many panels I will be creating. The code is in the form load function located.
Thanks,
Dim Pan As Panel
Dim RButton As RadioButton
For x As Integer = 1 To QuestionsQuantity Step 1
Pan = New Panel
Pan.Name = "Panel" & Convert.ToString(x)
Pan.Left = 300
Pan.Top = 100 + 52 * (x - 1)
Pan.Height = 48
Pan.Width = 280
Pan.BackColor = Color.Coral
Controls.Add(Pan)
For y As Integer = 1 To 7 Step 1
RButton = New RadioButton
RButton.Name = "RadioButton" & Convert.ToString(x) & Convert.ToString(y)
RButton.Left = 1 + 30 * (y - 1)
RButton.Top = 10
RButton.Text = Convert.ToString(y)
RButton.CheckAlign = System.Drawing.ContentAlignment.BottomCenter
RButton.TextAlign = System.Drawing.ContentAlignment.TopCenter
RButton.UseVisualStyleBackColor = True
Controls.Add(RButton)
Pan.Controls.Add(RButton)
Next
Next
I messed with it and took out the Panel section and just used the RadioButtons in order to see if i get seven of these. I can get seven if i ofset them in the y direction (.top) but it does not work for some reason in the x (.left) direction
For y As Integer = 1 To 7 Step 1
RButton = New RadioButton
RButton.Name = "RadioButton1" & Convert.ToString(y)
RButton.Left = 20 + (y * 30)
RButton.Top = 10
RButton.Text = Convert.ToString(y)
RButton.CheckAlign = System.Drawing.ContentAlignment.BottomCenter
RButton.TextAlign = System.Drawing.ContentAlignment.TopCenter
RButton.UseVisualStyleBackColor = True
Controls.Add(RButton)
Next
Please help me!
I finally got it. The problem was declaring the size of the RadioButton. It will be too big if not declared even if i make the spacing bigger.
RButton.Size = New System.Drawing.Size(17, 30)
That solved the problem.
You should be using a UserControl that contains your seven radio buttons.
For x As Integer = 1 To QuestionsQuantity
Dim pan As New QuestionUserControl
Pan.Name = "Panel" & Convert.ToString(x)
Pan.Left = 300
Pan.Top = 100 + 52 * (x - 1)
Pan.Height = 48
Pan.Width = 280
Pan.BackColor = Color.Coral
Me.Controls.Add(Pan)
Next
If sticking with your current code, remove this (you should be only adding it to the panel):
For y As Integer = 1 To 7
'// Controls.Add(RButton)
Pan.Controls.Add(RButton)
Next
As far as seeing the control, I'm guessing you aren't going "right" enough:
Dim leftMark As Integer = 20
For y As Integer = 1 To 7
'// code
RButton.Left = leftMark
'//code
leftMark += rButton.Width + 4
Next
with a Pan.Height = 48 there's not going to be much controls inside.
You add the button both to the panel an to Controls ?
Put the radiobuttons in a gridbox. You can dynamically add rows of radiobuttons as you wish. If this will work for you, I'll send a sample code when I get home.
