codeInfront:

<input type="button" onclick="JavaScript:clearSelections();" name="clear" value="Delete"/>

codeBehind:

public void Page_Init( object sende, System.EventArgs e )
{
if( ?input button has been klicked? )
{
....
}
}

In my code behind I want to reset an object when the button has been klicked. But how can I see if that has happened?
