Solution 1

Anything that's dynamically added after the viewstate is restored, does not exist for viewstate, and therefore has no events. You need to add it sooner. Read up on viewstate management and dynamic controls.

Thnxs Christian for ur suggestion...can u be more specific abt wht shud i do for firing the button click event..thanks in advance...

Correct. +5!

Specifically, you should do what I specifically said. It involves reading and learning.

@christian graus -It has nothing to do with ViewState. ViewState is responsible for maintaining the state of the controls in the control tree -- not the state of the control tree itself! . Dynamically created controls will not exist on the next postback unless you add them to the control tree once again....so dis issue need to be solved by loading control on every load..!!!

Christian Graus 7-Aug-12 3:39am

Correct. That is exactly my point. Later versions differentiate between control state and viewstate, but they are both part of the same thing, and both rely on the control always being created BEFORE viewstate is created. If you load it too late, it still will have no events, as it won't be part of the control tree when events are constructed

Solution 4

Call ur Button Click Event In your PageLoad

protected void Page_Load(object sender, EventArgs e)

{
Button.Click += new EventHandler(Button_Click);

}

void Button_Click(object sender, EventArgs e)
{

ButtonClick Code.....
}

Solution 2

when you are adding button on form run-time, Have you added Event-handler for click event of that button?

Happy coding!
:)
