avoid post back event

[PPCC]

I am developing web site using asp.net. I have 50 list box controls on the web form.
I want to cancel the selcted item from the listbox.
I am doing that using lstbox.Cancelselection mehtod but postback event fire again which
populate the all listboxes.
On form_load event i am already checking postback event as false.
Now my question is how do i avoid populationg listbox on click of clear button

In the Page Load event, check for

If Not Page.IsPostBack Then
'.....

Something to remember is that the Page Load fires before the button event. Meaning that even if you load the boxes on every load the clear will still or should still clear them.

Another thing if you Bind the list boxes on every load the SelectedItem will alway be the first item in the list because between it being select and the fireing of any server code using the selected. The list has been rebound and it's selected item set back to 0.

always bind a list inside a Not IsPostBack check.

Listen to the frog he is pretty smart
