I use the javascript:return on typical Gridview buttons. I have not used it on a common page button. I need to open a java Confirm window only if a flag is set like so:

private void checkBox1_OnCheckChanged(object sender, EventArgs e)
{
        Session["isChanges"] == true;
}

private void btnSearch(object sender, EventArgs e)
{
        if(Session["isChanges"] == true)
        {
             Session["isChanges"] = false; //reset flag
   
            //popup java confirm window
        }

        SaveChanges();
}

you can register client script block from code behind like this:-

// Form the script that is to be registered at client side.
       String scriptString = "<script language=JavaScript> function DoClick() {";
       scriptString += "alert('Are you sure you want to close me??');}<";
       scriptString += "/";
       scriptString += "script>";

           if(!this.IsClientScriptBlockRegistered("clientScript"))
              this.RegisterClientScriptBlock("clientScript", scriptString);

Open in new window

if(Session["isChanges"] == true)
        {
             Session["isChanges"] = false; //reset flag
   
            //place the code here....
        }

I cannot get your code example to work dymanicaly. I'm now using button attributes in the Page_Load().

if(...)
    btnSearch.Attributes.Add("onclick", "return confirm('Are you sure you want to proceed?')");
else
    btnSearch.Attributes.Remove("onclick");
