[Solved] ClientState Empty!

[Sylvain]

Hello!

I'm using a RadComboBox for ASP.NET AJAX.
I need to retrieve the value field in the Request.Form of the next page.
In order to do this, I did as told on this thred:
http://www.telerik.com/community/forums/thread/b311D-bcgmme.aspx

My problem is that the client state is filled only if the comboBox is openned by the user. If it isn't, the myCombobox_clientState stays empty.

Have an idea about this?

Thanks,

Sylvain.

Hi Sylvain,

I suggest you execute the following javascript code after the RadComboBox definition.

<script type=text/javascript>

function pageLoad()
{
  var combo=$find("RadComboBox1");
  combo.set_text(combo.get_items().getItem(0).get_text());
}

<script>

Thanks for this.

I've tried it, but the combo var stays null regardless the id passed in '$find("")'.

I've read here: http://www.telerik.com/help/radcontrols/aspnet%2Dajax/
that I need to give the clientId.

I generate my DropDownList in the .cs file.Then I affect the pageLoad call to the OnClientLoad event.

Am I going wrong?

Hi there:

I have the same trouble.

In prometheus and prior i have not trouble.

In radcontrols 2008 _clientstate will show nothing when i pass the combobox values to a different webpage (think on a combobox and a button with a postbackurl).

Hello John,

You can use the approach described by Rosi, however, I suggest that you get the client-side combo instance, like:

var combo  = $find("<%= RadComboBox1.ClientID%>");

Also, you could use the Telerik.Web.UI.RadComboBox.ComboBoxes array. Telerik.Web.UI.RadComboBox.ComboBoxes can be used to obtain an array containing all the client-side combobox instances.

Hope this helps.

Hello,

I've tried everything proposed here but nothing worked...
The $find never returns any object and the Telerik.Web.UI.RadComboBox doesn't exist. I can't find it while debugging. All I have is Telerik.Web.UI and other namespaces I actually don't really care.. :(

Hello Sylvain,

Is it possible that you are running the classic RadComboBox version. If so, you should use the tlrkComboBoxes array to obtain an array containing all client-side combo objects.

Getting the client-side instance of a specific combo when it does not reside in another control is done like:

var combo = <%=RadComboBox1.ClientID %>;

If this does not help, could you please isolate the problem in a small and running project and attach the files to a new support thread to test them locally.

Sincerely yours,
