In my Vb.net application I use rdlc report and ReportViewer. But it only loads report in the page_load event.
Here is my code
Private Sub report_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Me.displayTableAdapter.Fill(Me.aludbDataSet.display)
Me.ReportViewer1.RefreshReport()
End Sub
When I change it to Button_click event, it doesn't load the report. Code is here
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs)
Me.displayTableAdapter.Fill(Me.aludbDataSet.display)
Me.ReportViewer1.RefreshReport()
End Sub
I don't know why this happened. Because both are same code, only the way is different. Now, I want to load the report when the button is clicked. How to do that? Anyone help please. Thanks
try adding the "Handles" code
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles Button1.Click

I'm trying to make a tableLayoutPanel by code in Windows Form VB which can later be coded to add on extra rows and columns also by coding
When the form starts:
Private Sub form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles _MyBase.Load
Dim TLP As New TableLayoutPanel
'Edit all your properties: name, size, location, etc.
End Sub
Say when you click a button1:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Me.Controls.Add(TLP)
End Sub
Hope that helps.

Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click
WebBrowser.Show()
WebBrowser.WebBrowser1.Navigate("www.carsonmap.com/hidalgo/login.cfm")

I need help with this code I keep getting an error saying Null Reference.
I got the idea from this Youtube Video check out to see what I am trying to accomplish.
https://www.youtube.com/watch?v=9EJXzWasTq4&list=PL42055376AE25291E&index=41
They used two buttons to enter to the website I am trying to enter to a website By using one button any ideas why doesnt it work.
When you use WebBrowser1.Navigate - it just begins to load document, the document is not available right away.
You need to use WebBrowser.DocumentCompleted Event to place your code that works on document's elements. E.g. something like
Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click
WebBrowser.Show()
WebBrowser.WebBrowser1.Navigate("www.carsonmap.com/hidalgo/login.cfm")
End Sub
Private Sub WebBrowser1_DocumentCompleted(ByVal sender As Object, _
ByVal e As WebBrowserDocumentCompletedEventArgs) Handles WebBrowser1.DocumentCompleted
WebBrowser.WebBrowser1.Document.GetElementById("UserName").SetAttribute("value", "lrgvdc")
WebBrowser.WebBrowser1.Document.GetElementById("PW").SetAttribute("value", WebBrowser.TextBox2.Text)
End Sub
I'm trying to add a new row to a DataGridView from FORM 2 but I can not succeed, the code I tried is as follows:
FORM 2:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
FORM1.invoice_items.Rows.Add()
End Sub
Looking like it took time but can not find a solution, someone who can help me with my problem would be nice, Thank You.
Try this
This work only if you use a showdialog.
Form 2 :
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
'Pass the value to be added in the datagrid to form 1
Me.DialogResult=Windows.Forms.DialogResult.OK
End Sub
Form 1:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
If Form2.ShowDialog = Windows.Forms.DialogResult.OK Then
'Getthe value from form 2
invoice_items.Rows.Add()
End If
End Sub
I created a button and I need it to restart the form
I have no idea how to work on the visual basic what should i write
Private Sub Button2_Click_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
End Sub
Do you mean Application.Restart() ?
Private Sub Button2_Click_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
Application.Restart()
End Sub
Although in Visual Basic this does the same as in C#, it restarts the application not just clears the form.
In order to reload the form you simply need to do this in the form's Load event.
Me.Close()
Me.Show()
Try This..
Private Sub Button2_Click_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
Application.Restart()
End Sub
