Issue with finding element in grid edit with ascx WebUserControl

[Al]

Hi
I am really struggling to find a how to edit a textbox. I have a grid edited with a ascx WebUserControl. Within the ascx I the following 

var pSalesOrderNumber = $find("<%= txtOrderNumber.ClientID %>");
It is undefined.  I tried using  $telerik.findControl but still no luck. Sadly out of my depth.  Any help would be much appreciated

An acceptable workaround is to use RadTextbox instead of a textBox.  I would have liked to have solved this.

Hi Al,

The native asp:TextBox server control has no corresponding Client-side control object. To reach it on the client-side you will need to use the $get() method (or the document.getElementById() method) as a replacement for the $find():

var pSalesOrderNumber = $get("<%= txtOrderNumber.ClientID %>");

Please let me share some general information on this matter:

Most of the Telerik Controls expose also a client-side control object with its own client-side API. The $find() method would return the JavaScript object representing the client control. However, if you try to $find() an asp:Pane or asp:TextBoxl, it would return null as the Panel and the TextBox have no corresponding client-side object. Instead, you can use the $get() method that returns a DOM element but not a JavaScript object. The $find() and $get() methods are part of the ASP.NET AJAX Client Side Library. It is a feature of the framework that allows easy getting a reference to a Client-side Control object instance or to a native DOM element on the page. 

When it comes to getting a control on the client-side (such that has a client-side control object, e.g. RadTextBox), we have some of the common different approaches for getting a client-side reference to a control object listed in the following article:

• https://docs.telerik.com/devtools/aspnet-ajax/getting-started/work-with-controls/get-client-side-reference 

If this is not the case here, I would ask you to share the complete markup declaration of the page in question so I can get a better overview of the case and assist you more accurately.

I hope you will find this information useful.

Kind regards,
Doncho
