Item Template

Hello, i've got a couple of the comboboxes (combo1 and combo2) on a page, each of them has checkboxes...now, while I have seen and used the javascript method to update combo2 based on what someone checks on combo1, for certain requirements, I need to do this on the server side, using the checkbox's oncheckedchanged event, with autopostback true (otherwise, it doesn't do squat)

I also have everything withing an ajax update panel, but the checkboxes still cause a full postback...if I try to set the checkbox as the trigger for an async postback, I get the error saying the update panel can't find a control names chk1 (the name of the checkbox in the item template)

I even tried placing everything inside a RadAjaxPanel, and even then, the checkbox event causes a full postback...can anyone help me with this?

-----------------------------------

With that said, I'm trying to work from the server because when I work with the javascript, once I hit a button to do some server side process, combo2 acts, from the server side like it hadn't been changed at all...if I could resolve this, I wouldn't need to fire events from the checkboxes server-side...so if anyone has the solution for this, i'd be very grateful

I'm using both the combobox item template demo as sources as well as the Related Combobox demos, here are the links

http://demos.telerik.com/aspnet-ajax/combobox/examples/functionality/templates/defaultcs.aspx
http://demos.telerik.com/aspnet-ajax/combobox/examples/functionality/multiplecomboboxes/defaultcs.aspx

Thank you all in advance

----------------

Update:

Tried using RadAjaxManager instead of updatepanel:

<telerik:RadAjaxManager ID="rManager" runat="server">

AjaxSettings>

telerik:AjaxSetting AjaxControlID="chk1" EventName="CheckedChanged"

<UpdatedControls

<telerik:AjaxUpdatedControl ControlID="chk2"

/>

<telerik:AjaxUpdatedControl ControlID="silverlightControlHost" />

</

UpdatedControls

>

       </

telerik:AjaxSetting>

</

AjaxSettings><br

>        

</

telerik:RadAjaxManager>

chk1 is the checkbox item with the event. chk2 will be updated depending on what you check/uncheck, and silverlightControlHost is a div that contains a silverlight app that will also be updated...

While it doesn't give me the error the updload panel did, it still does a full postback...

Hope you can help me

RadGrid1_InsertCommand is not fired

Hi;
We inherit our Asp.Net pages from a page which is called PageBase instead of System.Web.UI.Page . PageBase which has controls over buttons and other things on the page also is inherited from System.Web.UI.Page. Well; the problem starts from here;
When we tried to write the example from " http://localhost:8301/radcontrols_aspnetajax/controls/examples/integration/gridandradasyncupload/defaultcs.aspx?product=upload " page our RadGrid1_InsertCommand is not fired. However; whenever Asp.Net pages are inherited from System.Web.UI.Page, RadGrid1_InsertCommand is fired. How can i solve this issue? Why this happens?

Telerik and no ajax?

I'd like to use the RadMenu with our search engine appliance from Adobe (ie. Omniture). Typically search engines don't support ajax well. How can I configure RadMenu manually to not require ajax?

Using RADGrid with editor

I have a RadGrid which displays a list of lesson plans.
When I click "edit" the text appears in the RADeditor (see Atached Image)
When I click the "save" button the data is saved in the database but the grid isn't updated.
If I click "Refresh" to rebind the grid, all the items are displayed in the list except the one I was editing.
Do you have any idea what I need to do to ensure updates are shown in the list when I click "Save"?

The code for the grid and editor are displayed below

Checkbox parameter value not being picked up

I've got a grid which has an EditForm:

<EditFormSettings EditFormType="Template">

<FormTemplate>

<asp:CheckBox runat="server" ID="chkPrintedPaper" Text="Printed Paper" Checked='<%# ConvertChecked(Eval("PrintedPaper")) %>' />

</FormTemplate>

</EditFormSettings>

ConvertChecked is a code-behind function which turns 1, 0, NULL into True, False, False respectively.

For my insert command:

InsertCommandType="StoredProcedure" InsertCommand="csp_reg_saveEMSite"

<InsertParameters>

<asp:Parameter Name="PrintedPaper" Type="boolean" />

</InsertParameters>

When I do a trace, the value of chkPrintedPaper isn't picked up (other fields, all textboxes, are fine). What do I need to do here?
