JavaScript with c# doesn't work

Question

LoadClientScriptMessage function doesn't work while Response.Redirect("SamePage.aspx"); works well!

if (command2.ExecuteNonQuery() == 0)
{
     LoadClientScriptMessage("Something went wrong!");
}
else
{
     LoadClientScriptMessage("It is OK!");
     Response.Redirect("SamePage.aspx");
}

Here is the implementation of LoadClientScriptMessage:

private void LoadClientScriptMessage(string message)
{
    StringBuilder script = new StringBuilder();

    script.Append(@"<script language='javascript'>");
    script.Append(@"alert('" + message + "');");
    script.Append(@"</script>");

    Page.ClientScript.RegisterStartupScript(this.GetType(), "Alert", script.ToString());
}

You want to show alert & redirect the user and complaining that it doesn't work ? — Ondrej Svejdar

Or is it the first call when if condition evaluates to true? — Abhitalks

When you call Response.Redirect("SamePage.aspx") will actually redirect the current request and you will not see any response rendered for the current request.

All you get here is a new page. If you still want to see the alert and redirect then remove Response.Redirect and redirect using javascript window.location.href

 LoadClientScriptMessage("It is OK!");
 //Response.Redirect("SamePage.aspx");
  Page.ClientScript.RegisterStartupScript(this.GetType(), "redirct", 
  "window.location.href='somepage'",true);

have you write Ajax.Utility.RegisterTypeForAjax(typeof(Sample)); at pageload? and add in web.config

<system.web>

<httpHandlers>
 <add verb="POST,GET" path="ajax/*.ashx" type="Ajax.PageHandlerFactory,Ajax"/>

 </httpHandlers>
 </system.web>

Response.Write("<script>alert('Alert Message')</script>");
