RadComboBox RenderClientStateField Example

[Ron]

HI there..

I cant seem to find an example on how to use RenderClientStateField method of the ComboBox to render the ClientStateField on a page.
Can someone please help me out.


Thanks,

Hello Ronak,

I have already replied to your support ticket. In addition, I would like to ask you to continue our conversation in the other ticket, in order to keep the correspondence consistent.

Hi,

Could you please share a link for Demo illustrating "Renderclientstatefield"  usefulness.

 

Thanks!

Hello Magesh,

I am sharing the reply from the support thread with Ronak:

The mentioned function is an inherited one and we do not recommend any modifications. Here is the body of the functions and the implemented logic :

public virtual void RenderClientStateField(HtmlTextWriter writer)
       {
           writer.AddAttribute(HtmlTextWriterAttribute.Id, ClientStateFieldID);
           writer.AddAttribute(HtmlTextWriterAttribute.Name, ClientStateFieldID);
           string clientState = SaveClientState();
           if (!string.IsNullOrEmpty(clientState))
           {
               writer.AddAttribute(HtmlTextWriterAttribute.Value, clientState);
           }
           writer.AddAttribute(HtmlTextWriterAttribute.Type, "hidden");
           writer.RenderBeginTag(HtmlTextWriterTag.Input);
           writer.RenderEndTag();
       }

 

With that said, this is not called explicitly and there are not demos about it. It is automatically called when creating any Telerik control inheriting the RadDataBoundControl. Its purpose is to create a hidden input, where useful information can be stored on the client, and then accessed on the server-side upon postback.
