Hello,

i have one more problem which i am not able to solve.
I want to compare 2 textboxes on btnCompare_click, when they are equal to each other then ASP.NET has to show a confirmbox where i can select ok or cancel. I know how to show a confirmbox by adding the attribute to the button in the page_load.
btnCompare.attributes.add("onclick", "return confirm_copy")
But when i add this to the button btnCompare then the confirmbox is always showed and that's not what i wanted. What i did to resolve this, i made a dummy button where i attached the confirm box to but know i have the problem to trigger the btnDummy_click event. When i click the button btnCompare and the 2 textboxes are equal to each other then i want the confirmbox to be showed.

Do you understand what i mean ??
I have been searching for a solution but nothing worked out ?

So you are doing the comparison on the server side? Then you need to output a scriptlet to the client that shows the confirm dialog.

RegisterStartupScript("confirm", "<script language=""JavaScript"">confirm(...);</script>")

The hard part about this is that you'll have to figure out what to do with the return of the confirmation dialog. Remember, the confirmation is client-side so you'll have to take some client-side action to deal with the result of the confirmation.

I've handled all of this.
The only problem stays how to trigger the button event when i click another button?
Ive tried it with RaiseEvent but wouldn't work ?
Have you got any ideas ?

Where are you trying to have this happen? You should be able to just call the other button's event handler from the handler of the button you are actually clicking on. Just call it as a regular function call and pass the arguments (sender, e).
