Is it possible to anchor a control to another control?
Lets say i want my Button1 to keep its 4px distance from Textbox1 control without
using FlowLayoutTable control?
"Why would be this advantageous?" - one could ask
Well let's say you have a SplitContainer with a vertical splitter and you have Textboxes
in SplitContainer.Panel1 which are anchored to the left and right but their maximum size's
width is smaller than you allow to the SplitContainer.Panel1's width to have (maybe
because you want text to show up there or because additional padding or whatever,you name it)
Now let's say you also have a button next to Textbox1 and you dont want Textbox1 to be
overlapped by the Button1 because its extends to far.
If i want to have my textbox fill the SplitContainer.Panel1 in a fashion that it leaves space for
Button1 control while still both of them are anchored to the right how would i do it?
I extensively use TableLayoutPanels and FlowLayoutPanels to accomplish this. For you specific circumstance I would use a TableLayoutPanel with three columns and a row for each TextBox.
Column 1: Auto-width, contains Labels all with AutoSize = True.
Column 2: 100% width, contains TextBoxes all with Anchor = Left, Right.
Column 3: Auto-width, contains the Button in the appropriate row.
Next, I set all text boxes, except for the one next to the button, ColumnSpan = 2. Then just put the TableLayoutPanel in the SplitPanel and set Dock = Fill.
it will be a sequence in live which should be flow out from left and keep working lets the right side should be layout.
List item safty cares should be provided.
List item all things that use in this method should be provided and be check;

I am trying to set the color of an indicator to different colors based on different values, like 1 = red, 2 = blue etc. Using guidance from a Youtube video (accessible using this link: https://www.youtube.com/watch?v=czUmPQmKmGU), I have created a Colors[4] control for the indicator I have after changing it to the "write" function.
The Problem on the front panel is that I am getting a control with numbers instead of a color box where I can select the colors to show based on the value. This was the control I got instead.
This is the control I am trying to achieve (below):
Is there any way that I can get the color box on my control instead of the number controls? I am not sure if it can be changed through a control on the front panel or something but what I have tried so far keeps leading me back to this problem.
Any advice is much appreciated
A color box control is just a U32 number (three bytes for RGB and one which is always 0), which is why that's what you get.
There is a right click plugin which adds a replace with color box option directly to the right click menu of unsigned 32 bit numbers, but I don't remember if it ships with LV or not.
If you don't have that, you can always just right click the indicator inside the cluster, select replace and navigate the palettes to find the color box. You can also copy a color box and then select the indicator and paste, which replaces the selected control.
The color[4] is actually an array of 4 colors (UInt32 as Yair said), that define 2 color gradients, one for the 'Off' state, and the other for the 'On' State of the control.
If you want to set the control's color, you will have to define all 4 of them.
My Access REPORT has a text box with the Record ID that looks like a button with an on click event to go to a form for that specific record. This works great, but when I return to the report I cannot see which record was clicked. I want to temporarily change ONLY the record that was clicked until another record is selected.
The reason I want this on a report and not a form is because I want the user to have a quick way to proof read in the format needed to print, and make a change or check a detail if necessary, then update the report AFTER all proof reading and updates are completed and before final print. But with many records on the screen it is easy to lose track of which record you were checking when returning from the form.
I tried:
Private Sub btn_txt_GoToTransaction_Click()
Dim vColor
vColor = RGB(51, 204, 51) 'green
Me.btn_txt_GoToTransaction.BackColor = vColor
DoCmd.OpenForm "Account_frm", acNormal, , "[TransactionID]=" & Me.TransactionID
End Sub
But this does not work because every button turns color not just the selected record.
Any suggestions? Thanks.
This is a great question because there are many benefits to highlighting a row or item in an Access Report. You are not able to just change the button color in one row only, but you can highlight the whole row so the user knows where they were.
Here are two methods to accomplish this:
Method 1 - Click on a Label
This works great in newer versions of MS Access when using Report View. Use a Label Control instead of a Button. You could make the label look like a button if you format it that way. I prefer to stretch an invisible Label across the whole row on top of all the other controls in that row. Then if you click anywhere in the row, it automatically selects that row and then runs whatever code you have in the OnClick Event. This works best if the Label is not linked to a Text Box.
This picture shows an example of how this method looks. You can click anywhere in the row and it highlights that row with the red outline and grey background.
This is very simple and works well but there are a couple disadvantages:
1- You can not change the color of the highlight.
2- If any of the text boxes CanGrow, the row height may be higher then the Label and create areas where the invisible label doesn't capture your click.
3- Clicking on a Text box does not work for this method.
Method 2 - Change Color of a Text Box
In order to just highlight one row or one piece of data in a report, we can use the "FormatConditions" property. This is the same as Conditional Formating from the MS Access design interface but we are going to change it programmatically on the fly. You can't do this with a button or label - it needs to be a Text Box with unique data, such as your TransactionID.
This picture shows an example of how this method looks. You can set the color of the highlight if you follow the steps below.
STEP 1) I recommend that you add a text box to your report that stretches from the left to the right, set the Back Color and Fore Color to White, set the Control Source to TransactionID, and set the Name to TransactionID. Then right click on this text box and select Position > Send To Back. This works best if the other text boxes and labels on the report have a transparent background.
STEP 2) Add this code:
Private Sub HightlightRow(intRowID As Integer)
With Me.TransactionID.FormatConditions
.Delete
With .Add(acFieldValue, acEqual, intRowID)
.BackColor = vbGreen
.ForeColor = vbGreen
End With
End With
End Sub
STEP 3) Also change your button code to call this subroutine like this:
Private Sub btn_txt_GoToTransaction_Click()
HightlightRow Me.TransactionID.Value
DoCmd.OpenForm "Account_frm", acNormal, , "[TransactionID]=" & Me.TransactionID
End Sub
STEP 4) I like to set it up so if the user clicks anywhere in the row, it will pop up with a modal with more detail regarding that row. Also, the user can't make any changes to the data in the Report View, so I use the pop up modal to allow changes. To accomplish this, I do a couple more things:
First, we need to add the code to the OnClick event for every control in that row. Ofcourse, each OnClick event will simply can that subroutine HightlightRow Me.TransactionID.Value
Second, if the user clicks on a Text Box, the Text Box gets the focus and hides the highlight. Therefore, I like to set the focus to something else. In your case, you could set the focus to the button by adding this line to the end of the HighlightRow subroutine: btn_txt_GoToTransaction.SetFocus
In my case, I am not using a button, so I set up a tiny Text Box with = " " (just an equal sign a space in quotation marks) as the Control Source. Then I position this tiny Text Box to the far right. And in the HighlightRow subroutine, I set the focus to this textbox.
STEP 5) You may also want a button or method of removing the highlight. To do that simply have the code run this line:
Me.TransactionID.FormatConditions.Delete
I try to implement the following in winform vb net project (I see this work in an app written in delphi).
I wish to hide or set visibility to false of the bottom row that partially visible in dgv that is docked to fill.
I tried to implement something like this:
DataGridView1.Rows(DataGridView1.DisplayedRowCount(true) - 1).Visible = False
I think it should be called during DataBindingComplete and Resize/scroll events, but it doesn't work.
Do you have any ideas / solutions?
So what I use on one of my datagridviews is:
Dim ind As Integer = 0
ind = DataGridView1.Rows.Count - 1
DataGridView1.Rows(ind).Visible = False
which hides the last displayed row of the datagridview.
You requirement sounds somewhat odd. Your comment ”I wish to hide or set visibility to false of the bottom row that partially visible in dgv that is docked to fill.”... I am curious how you would know this is the last row? Is it not possible that there are more rows below the last one visible? If the scroll bars are available you should see the vertical one if rows go beyond its bounding box. If one of the rows is cut in half by the bounding box and there is more than 1 row below this row, then making invisible/hiding/deleting that row will simply move the next one up.
Since the DataGridView is docked you may have to resize the rows manually if you do not want the rows to be split by the bounding box. Another possible solution is to use the DataGridViews AutoSizeRowsMode Like below.
dataGridView1.AutoSizeRowsMode = DataGridViewAutoSizeRowsMode.DisplayedCells;
This will set the rows so that a row will not be chopped if it is outside the bottom of the bounding box. The rows will auto size to fit evenly There are seven (7) AutoSizeRowsMode options and I am guessing one of them may do what you are looking for. I am guessing DisplayedCells may work for what you describe. If the grid is re-sized often, you may have to implement this row resizing. Hope this helps.
I have used CheckedListBox control in vb.net application.
I have several items as follow, item 1, item 2, item 3........item 100.
Now, i want all these items to arrange into three columns and then appear verticle scrollbar.
But, in CheckedListBox, it appears as horizontally. i want it to appear horizontally for just three columns and then vertical scroll should enable.
Can you please suggest if possible in CheckedListBox control or any other control and if possible then how i would have to set its property to achieve this.
I don't think you can do that in a CheckedListBox....
You could create a FlowLayoutPanel, with a fixed width and add AutoScroll = True.
Then add a number of CheckBox controls to it.
You could have problems regarding column alignment and margins. If that's the case, you can set the checkbox Autosize = False and make them a little larger (in order to contain the text)
Or you can reduce the Height of the checkboxes to reduce spaces (is this what you want?)
eg. Height = 15
Use repeat direction =horizontal and repeat column =3 for checkbox list
I'm trying to use a TableLayoutPanel to align a few controls on a form next to their labels like so:
Label1 [combobox ]
LongerLabel [longer combobox]
But when I run the project and grab the right hand side of the form and shrink the form, the combobox doesn't resize, it gets cut off... Now, I were to not use the TableLayoutPanel, but just anchor a combobox to a form's edges, it will resize properly. What am I doing wrong with the TableLayoutPanel?
I found the answer here:
http://www.tech-archive.net/Archive/DotNet/microsoft.public.dotnet.framework.windowsforms.controls/2006-12/msg00209.html
So I set the first column with the label to autosize (I have the label fill docked in the cell and the text alignment set to middle left). Then dock fill the combobox in the second column. Then, set the second column's size type to 100%, NOT autosize. I don't know why it works, but it does.
