Solution 1

document.all is a non-standard extension that even Microsoft removes it from IE.
So don't use it! Use document.getElementById('TextBox2'). It's standard and supported by every browser...

It became obvious - from comments - that the source of the HTML is an ASP.NET page.
ASP.NET creates it's own ids - based on what you entered - to ensure unique id fro page.
For details you may see INamingContainer[^].

It means that the id you give (TextBox2) is valid only for server-side. To access the very same object on client write your JavaScript like this

JavaScript

document.getElementById('<%=TextBox2.ClientID%>')

hi
i changed to
document.getElementById('TextBox2').value = window.showModalDialog("browseDirectory.aspx", 'jain', "dialogHeight: 560px; dialogWidth: 360px; edge: Raised; center: Yes; help: Yes; resizable: Yes; status: No;");

but error came again like this,
Line: 112
Error: 'document.getElementById(...)' is null or not an object

Can you show us the rest of your page, especially where TextBox2 declared?

There is no element named TextBox2 in this code. So it can not be found...
