Hi, u can use the following server side function. if (!(this.IsStartupScriptRegistered("Startup"))) Page.RegisterStartupScript("StartUp","fun('"+ arg1 + "')");

_AK_

exactly same way you can do as psamy said. also you can even write complete function in code behind itself.

something like this you can use..: string str = ""; str += "function Focu(){"; str += "document.getElementById('TextBox3').focus();}<"; str += "/"; str += "script>"; if(!IsStartupScriptRegistered("Test")) { Page.RegisterStartupScript("Test",str); }</code> <div class="ForumSig">Best Regards, Apurva Kaushal</div></x-turndown>

There are several ways. You could insert a value in the function: var x = <asp:Literal id="objValue" runat="server" />; and in the codebehind insert the value: objValue.Text = "42"; You could make the body tag accessible from codebehind: <body id="Body" runat="server"> and set the onload event from codebehind: Body.Attributes["onload"] = "somefunc(42);"; You could add the code in a script tag: this.ClientScript.RegisterStartupScript(this.GetType(), "init", "somefunc(42);", true); Note that if you use RegisterStartupScript the code will run while the page is loading, not when it has finished loading, as it does when you use the onload event.
