Hi Experts,

How can I create group of command buttons dynamically  in a group box . For example I want to create 50 command buttons, 10 in each row and 5 in each column.

Thank you.

Dim btn As New Button
panel1.Add(btn)
btn.Name = "Save"
btn.Width = 120
btn.Height = 64
You need a panel control to add your button.

Something like this:
Public Class Form1
	Private groupBox1 As GroupBox = New GroupBox()

	Private Sub OnLoad(ByVal sender As Object, ByVal e As EventArgs) Handles MyBase.Load
		Dim x As Integer = 3
		Dim y As Integer = 12
		For i As Integer = 1 To 50
			Dim button As New Button() With {.Location = New Point(x, y), .Name = String.Format("btnDynamic{0}", i), .Text = String.Format("Button {0}", i)}
			If i Mod 10 = 0 Then
				x = 3
				y += button.Height + 6
			Else
				x += button.Width + 6
			End If
			AddHandler button.Click, AddressOf OnClick
			groupBox1.Controls.Add(button)
		Next
		groupBox1.AutoSize = True
		groupBox1.Name = "gbDynamic"
		groupBox1.Text = "Dynamic Group Box"
		Me.Controls.Add(groupBox1)
		Me.Size = New Size(groupBox1.Width + 20, groupBox1.Height + 60)
	End Sub

	Private Sub OnClick(ByVal sender As Object, ByVal e As EventArgs)
		If TypeOf sender Is Button Then
			Dim btn As Button = DirectCast(sender, Button)
			MessageBox.Show(String.Format("Button - {0}; Name - {1} was clicked", btn.Text, btn.Name))
		End If
	End Sub
End Class

Open in new window


Produces the following output -Capture.JPG

I would use a FlowLayoutPanel instead of a GroupBox. It has being designed exactly for the purpose that you asked for, and its big advantage over the GroupBox is that it will automatically place the controls for your, either in line or in columns, with specifications about the distance between the controls and a few other things defined in its properties.

You use code similar to the one suggested by it_sauge, but can forget agout the whole x,y stuff. Simply add the buttons to the FlowLayoutPanel instead of the GroupBox.
