Single Event handler for multiple linklabels

[shabbu_1980]

Hi,

I have derived a class from linklabel class and created around multiple linklabels dynamically. The objects on these link labels are stored in an arraylist. I want to write a single event handler for all these links. How do i achieve this??

thanks and regards

First write the Event Handler (without the Handles clause):

Private Sub Generic_Label_Click(sender As Object, e As EventArgs)
Dim lbl As Label = CType(sender, Label) ' Cast to the label
'Do Whatever
End Sub


Now, when you create the label add a handler to the event using the AddHandler statement:

Dim lbl As New Label
Me.Controls.Add(lbl)
AddHandler lbl.Click, AddressOf(Generic_Label_Click)


I hope its clear

Dim lbl As New Label
Me.Controls.Add(lbl)
AddHandler lbl.Click, AddressOf(Generic_Label_Click)

you could use a AddHandler lbl.command as well to make it work. remember the syntax is AddHandler Object as Event, Object as Delegate.

If you want to store key values within ur label you could use the commandarguments to do that. Let me know if u want to talk more about command arguments but as jhammer described it should solve ur problem.
