Solution 1

I think that the line that links to the external JavaScript should be moved to the HEAD section of the masterpage. That's this line;

ASP.NET

<script type="text/javascript" src="JScript.js" language="javascript"></script>

"It call function if der is only alert message in function but when i add the if(form1.TextBox1.value=="xyz") click event not calling d function. I can't understand what is d reason behind it."

der is only a word in German. d is a letter not a word. Don't talk like a retard, you have a full keyboard in front of you.

If your control even called TextBox1 on the client ? You need to use the ClientID property, not the name you give on the server.
