[Solved] Reach javascript var content on server side with radAjaxManager.FocusControl()

[alsi]

Dear Developers!

I would like to know (is it possible?):

client side:
<script>
var actElement='ctl00_MainBody_txtName';
</script>

server side:
radAjaxManager.FocusControl(here reach - write- js var content) so look like this

radAjaxManager.FocusControl("ctl00_MainBody_txtName");

is it possible to reach js var on server side somehow?

thanks

Hi alsi,

Using a hardcoded ID is not a good idea. A better approach would be to get reference to the ClientID of the control on the server and set focus to it.

Hi!

I don't use hard coded id-s. the thing what I exactly want:

I have two (or more) textboxes:

txtName
txtAddress

they have TextChanged event hadlers.
on aspx page I would like to do the following:
<asp:TextBox runat="server" ID="txtAddress" onfocus="actElement='<%# ClientID %>'" AutoPostBack="true" OnTextChanged="txtAddress_TextChange"  />

and after ajax Postback, I loose the focus, so I need to know the clicked textbox before postback.
imagine I have 20 textboxes and client don't want to fill in a determined order.

how can I do this?
thanks

The following solution helped:

1. Create js focus setter function:
 <script language="javascript" type="text/javascript">
   var actElement;
  
   function focusActElement()
   {
        if(actElement != '')
            document.getElementById(actElement).focus();
   }
    </script>

2. To textboxes add onclick client side event with ClientID in the following way:
<asp:TextBox runat="server" ID="txtState" onclick="actElement='need ClientID here'" /> - You need to do on the server side:
txtState.Attributes.Add("click", "onfocus=actElement='" + txtState.ClientID + "'");

3. On Page_Load (Page.IsPostback) event call use RadAjaxManager:
radAjaxManager.ClientEvents.OnResponseEnd = "focusActElement";
and this use actElement var to set the focus.

this works for me.
