i have server side command button, when i click that buton it should call
javascript function and after that it should execute the server side code. is
it possible? can anyone give me a idea.

Bala,

The answer is yes. In your code behind, you can add the javascript at run
time to the button. As an example, lets say you have a button called
btnSearch and you want to call a function called validateSearch() the code
would resemble the following in your page_load or something:

btnSearch.Attributes.Add("onClick", "validateSearch()");

Then for the server side click event, wire it as your normally would.

Here's some server side code that uses javascript to display a confirmation
message.
myDeleteButton.Attributes.Add("onclick", _
"return confirm('Are you sure you want to delete?');")

In this example, the Delete button will post back only if the person
confirms they want to delete. Otherwise your server code is never called in
response to the button click.
