Calling a Javascript function within C#

Question

I am trying to pop something based on a condition... but it is not working... and I am kind of a newbie at this so I appreciate the help

if (myFileName == OldFileName)
                {
                    btnSubmit.Attributes["OnClick"] = "return confirm('This file already exists, do you want to replace it?');";
                }

This is not being call for some reason.. here is the asp code

asp:Button class="Button" ID="btnSubmit" CausesValidation="True" Text="SUBMIT" runat="server"
            OnClick="btnSubmit_Click"></asp:Button>

From the code in the question, it looks like you're trying to bind the JS function, not call it. — Matt Ball

Are you familiar with jQuery? I like to keep javascript out of my code behind pages. Let me know if you would like an example in js or jQuery. — webtrifusion

use a ScriptManager.

ScriptManager.RegisterStartupScript()
ScriptManager.RegisterClientScriptBlock()

Yes, If the validation is being done on the server-side then you will have to show the alert/confirm after the page posts back to the browser.
