Using RadScriptManager for RegisterStartupScript

[Matt]

Hello,

I have a RadTreeView that has nodes that use NodeExpandMode.ServerSide and I need to have the web page focus on the selected node after post back. I found the following code from these forums to do that:

ScriptManager.RegisterStartupScript(
this, GetType(), ClientID,
string.Format("Sys.Application.add_load(function(){{$find('{0}').get_element().focus();}}, 0);", AppTreeView.ClientID),
true);

Unfortunately, this project was made in Visual Studio 2005 which only has the .NET version of 2.0 which doesn't have the ScriptManager class.

I was wondering if RadScriptManager would be able to provide this functionality, and if so, could I be provided with an example on how to do this?

Thanks,
Matt

Hi Matt,

Here is an example how you could achieve it with the RadScriptManager.

protected void Page_Load(object sender, EventArgs e)
{
    RadScriptManager.RegisterStartupScript(Page, Page.GetType(), "1", "Sys.Application.add_load(function(){{alert('success');}}, 0);", true);
}

I've tried your solution however it doesn't work and I get these errors in the browser:

1. ASP.NET Ajax client-side framework failed to load.

2. 'Sys' is undefined.

I read that "'Sys' is undefined" could be due to the script manager not being declared in the .aspx file, but it is:

<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="tWebUI" %>

<tWebUI:RadScriptManager ID="RadScriptManager1" runat="server">
        </tWebUI:RadScriptManager>

Thanks,
Matt

Hi Matt,

It is really strange that the ajax framework is not loaded. Could you please test the attached page at you side. Which version of our controls are you using?

I'm using version 2013.1.403.35 of Telerik.Web.UI. I moved some things around and now I'm getting the following:

Well I fixed the above but I'm back to my original errors...

Hello Matt,

Could you clarify that you tested the sample page from my previous post and it is not working properly at you side. In case that everything is working properly could you please send me a live URL or setup a runnable sample based on the provided page that reproduces the problem and send it back for a local test.

This works but I need it to wait until an action has occurred.... like clicking a single RadButton. How do I get it to wait until after that postback is complete?

[Matt]

Nevermind, just add it after the actions in the job completes... long day....

Hello Matt,

I am still having problems, 

I am using <Telerik:RadAjaxManager> to stop the page jumping, <Telerik:RadScriptManage ID=“xxx” runat=“Server”> for the javascripts

I am going to rebuild the page step-by-step to find the problem as in a scratch project it seems to work, if this doesn’t work I will send you a copy. If I may

Regards,

Michael

Hи Michael,

It would be very useful to provide a sample runnable project along with instructions of how to replicate the problem and the error that you get.

If you want to disable the subsequent clicks with RadButton, please set its SingleClick="true" property as shown in this demo.
