Adding events dynamically
Here's a scernerio that will get what I am trying to accomplish....
Say I have a form with a textbox to enter a number and a button called "Create" When a user enters a number and clicks create the form gets populated with the number of buttons entered in the textbox and the title of the buttons are labeled by consecutive numbers.
For example if you enter 5 the form will populate with 5 buttons labeled button1, button2, ...button5
When you click on these newly created buttons a messagebox will popup stating the buttons name开发者_C百科.
Basically I need to know how to create events and populate them with code I guess
dynamically.
Please respond in a solution for a windows app not web. No JavaScript.
Please can someone respond with a code example this idea is a little foggy to me
'Make sure that the textbox contains a number.
If IsNumeric(TextBox1.Text) Then
'Make sure that it's a positive number.
If CInt(TextBox1.Text) > 0 Then
For i = 1 To CInt(TextBox1.Text)
Dim x As New Button
x.Name = "Button" & i.ToString
x.Top = 100 + (i * 30) 'To avoid stacking.
AddHandler x.Click, AddressOf y 'Add the event here.
'Add it to the form.
Controls.Add(x)
Next
End If
End If
Private Sub y(ByVal sender As System.Object, ByVal e As System.EventArgs)
MsgBox(CType(sender, Button).Name)
End Sub
