Object reference not set to an instance of an object.

[Kiran More]

WebControl button = (WebControl)Page.FindControl("btn_Delete");

button.Attributes.Add("onclick", "return confirmDelete (this.form);");

confirmDelete is the method written in Javascript.


I am getting following error message as,

Object reference not set to an instance of an object.

Hy Kiran,
Are you sure that this control exists on the page? FindControl returns
a null reference if it doesn't find the control. This seems to be your
problem, that is the caus of your exception.

Maybe just set the OnClientClick property of the button instead of
going to the trouble of trying to find it.
