Question

Ok so i’ve been struggling to get my head around this for a few fays not and need some help.

so i have a series of panels that are generated

example:

For i as integer 1 to dt.rows.count
    dim subpan as new panel
    *Code for creating panel"
Next

the problem is i need to be able to add event handlers to each of them including, click, mouseEnter and mouseLeave but i can’t figure out how to index each panel so that they can be accessed and identified. i tried using a property but that didn’t seem to work or i was doing it wrong.

thanks in advance for the help.

Answer 1

You want the AddHandler function:

For i as integer 1 to dt.rows.count 
    dim subpan as new panel 
    subpan.ID = "subpan1"  ' REQUIRED AND MUST BE UNIQUE
    AddHandler subpan.Click, AddressOf subpan1_Click  ' CLICK EVENT HANDLER ALSO UNIQUE
    ' ETC.
Next 

Private Sub subpan1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs)
    ' CODE TO HANDLE CLICK EVENT
End Sub

I should mention that you can route all click events to the same event handler, they don’t have to be unique unless each panel requires custom logic.
