Hi,

I have a code that uses a confirm box from javascript. I call it from code behind using

ClientScript.RegisterClientScriptBlock(this.GetType(), "Error", "Confirm('Do you want to overwrite the file?');");

.. it does not pop-up when it passes to this line. What it does is it continues to the next line and then the dialog box pops-up when it reaches the last line of the function. Any ideas?

Thanks,

Your code is server side code, all it is doing is saying 'this script should be rendered in the response'. When you hit that line of code, it won't pop up in javascript - because it hasn't returned to the client yet - you're still running server side code.

You function will need to finish, it will register the script on the page and then it will be processed on the client by the browser

hi,
you need to indicate whether the script provided in the script parameter is wrapped with a <script> element block or not. Re write the code like following,
ClientScript.RegisterClientScriptBlock(this.GetType(), "Error", "Confirm('Do you want to overwrite the file?');",true);
adding "true" value indicates to add script tags. Hope this will help.
