I am dynamically generating button controls on a panel control on a web
form as shown:
For Each aColorName In en.GetNames(en.GetType)
Dim btn As New Button()
btn.ID = aColorName
btn.BackColor = System.Drawing.Color.FromName(aColorName)
btn.CommandName = aColorName
btn.CommandArgument = aColorName
pnlColor.Controls.Add(btn)
Next
I would like to access the button?s onCommand method programmatically.
Can I? If so, How? If not,any suggestions would be helpful
Thanks
Dave

Try adding:
btn.OnCommand="aColorName_Command"
this will tie the event handler to the button object
Then create the event handler............
Sub aColorName_Command(sender As Object, e As CommandEventArgs)
'Do stuff in here ie....
myLabel.Text = e.CommandName & " = " & e.CommandArgument
End Sub
Hope this helps

Thanks for the tip. I cannot add the code as you suggested I receive the
following when attempting to either build and browse or just browse from
within VS.NET
error BC30390: 'System.Web.UI.WebControls.Button.Protected Overridable
Overloads Sub OnCommand(e As System.Web.UI.WebControls.CommandEventArgs)' is
not accessible in this context because it is 'Protected'.
Any suggestions?
