RAdAjaxManagerProxy problem

[umut]

Hi, I have a masterpage and a content page. In content page i have 3 radcomboboxes. I want to fill the second one with the selection of first one. So i have a radscriptmanager in masterpage, and radajaxmanagerproxy in the content page. I added update properties to ajaxmanager

<telerik:RadAjaxManagerProxy ID="RadAjaxManagerProxy1" runat="server">
    <AjaxSettings>
        <telerik:AjaxSetting AjaxControlID="RadEkon1">
            <UpdatedControls>
                <telerik:AjaxUpdatedControl ControlID="RadEkon2" />
            </UpdatedControls>
        </telerik:AjaxSetting>
    </AjaxSettings>
    </telerik:RadAjaxManagerProxy>

and in RadEkon1 selectedindexchanged event i have the code to fill Radekon2, also the autopostback=true;

Now, when i made a selection in RadEkon1(radcombobox), it postback the entire content page but does not trigger the selected indexchanged event. Is there an answer for this?
Thanks in advance,
Umut

Hello umut,

Could you please elaborate a little bit more on the issue. Do you observe the same behaviour if you remove the Ajax from the page? Also is the application behaves the same way if you use regular asp UpdatePanels instead RadAjax?

I remove Ajax as you said from content page, combobox made the postback, but the event still not triggered. Using asp:UpdatePanel did not work for either... I recreate the scenario in another project (as 1 master page with radscriptmanager adn rad ajaxmanager, and the content page with radajaxmanagerproxy and 2 radcombobox), but in my main project it still does not work :(

Hello umut,

Please make sure the event handler is properly attached. You can post the RadComboBox markup as well as the handler code if you need further assistance.

Here is my combobox markup

<telerik:RadAjaxPanel ID="RadAjaxPanel2" runat="server" Height="200px" HorizontalAlign="NotSet"
                                    LoadingPanelID=""  Width="300px">
                                    <table style="width: 100%">
                                        <tr>
                                            <td style="width: 170px; height: 18px">
                                                <asp:Label ID="Label14" runat="server" Text="Ekonomik Sýnýflandýrma :" ToolTip="Ekonomik Sýnýflandýrma"></asp:Label></td>
                                        </tr>
                                        <tr>
                                            <td style="width: 170px; height: 32px">
                                                <telerik:RadComboBox ID="RadEkon1" runat="server" AutoPostBack="True" DropDownWidth="200px" Height="250px"
                                                    LoadingMessage="Yükleniyor..." OnSelectedIndexChanged="RadEkon1_SelectedIndexChanged"
                                                    Skin="Web20"  ToolTip="Ekonomik Sýnýflandýrma Seçiniz"
                                                    Width="150px" AppendDataBoundItems="True">
                                                </telerik:RadComboBox>
                                            </td>
                                        </tr>
                                        <tr>
                                            <td style="width: 170px">
                                                <telerik:RadComboBox ID="RadEkon2" runat="server" AutoPostBack="True" DropDownWidth="200px" Height="250px"
                                                    LoadingMessage="Yükleniyor..." OnSelectedIndexChanged="RadEkon2_SelectedIndexChanged"
                                                    Skin="Web20"  ToolTip="Ekonomik Sýnýflandýrma Seçiniz"
                                                    Width="150px" AppendDataBoundItems="True">
                                                </telerik:RadComboBox>
</telerik:RadAjaxPanel>

And here is the event handler

protected void RadEkon1_SelectedIndexChanged(object o, RadComboBoxSelectedIndexChangedEventArgs e)
    {
        checkDdlEkonomik1 = true;
       Some  SQL And data binding to RadEkon2;
    }

I solved the problem :) It's because of an asp Validator in the content page. Radcombobox Causevalidation was set to true(defaultly i think) , although i didn't assign it to the validator, it still used it. By the way, thanks t telerik team for helping very fast...

Sincerely, Umut
