Here is snippet of my problem
IF Condition1 then
RemoveHandler lblCntrl.Click, AddressOf lbl_ShowItem
AddHandler lblCntrl.Click, AddressOf lbl_ShowMaker2
elseif Condition2 then
AddHandler lblCntrl.Click, AddressOf lbl_ShowItem
RemoveHandler lblCntrl.Click, AddressOf lbl_ShowMaker2
end if
After the above block is executed I try to click on the label.. I have both
the "lbl_ShowIt em" and "lbl_ShowMaker2 " methods executed. I had to go
include the same IF check inside each method to prevent... Why is the Remove
Handler not removing the old method and adding a new one for the same click
event. Anybody have ideas??
Thanks

It doesent remove the method, it simply attaches/removes the method to the
event.

I tried this out, both Labels have their clicks serviced until button one is
pressed, then only label2 works.
\\
Private Sub Label1_Click(By Val sender As System.Object, ByVal e As
System.EventArg s) Handles Label1.Click
MessageBox.Show ("Label1.Clicke d")
End Sub
Private Sub Label2_Click(By Val sender As System.Object, ByVal e As
System.EventArg s) Handles Label2.Click
MessageBox.Show ("Label2.Clicke d")
End Sub
Private Sub Button1_Click(B yVal sender As System.Object, ByVal e As
System.EventArg s) Handles Button1.Click
RemoveHandler Label1.Click, AddressOf Label1_Click
End Sub

What's 'Condition1' and 'Condition2'? Your code should work.

I want to be able to remove it from the page using javascript.
I've tried to delete the html element that contains the code but it keeps playing in IE. In FF it stops playing but I can't tell if it is removed or not.
Can I do it in javascript or maybe I need a FLASH script to do it?
