    Hi telerik team.


    I have some questions, i´m working with a user control like this:

    <telerik:RadAjaxManagerProxy runat="server">
             <telerik:AjaxSetting AjaxControlID="cbTaxesGroup">
                    <telerik:AjaxUpdatedControl ControlID="cbTaxes" />

        <div class="col-md-10">
            <telerik:RadComboBox runat="server" ID="cbTaxesGroup" AllowCustomText="false" EmptyMessage="Selecciona" AutoPostBack="true"               OnSelectedIndexChanged="cbTaxesGroup_SelectedIndexChanged"></telerik:RadComboBox><br />
            <telerik:RadComboBox runat="server" ID="cbTaxes" AllowCustomText="true" MarkFirstMatch="true" AutoPostBack="true" OnSelectedIndexChanged="cbTaxes_SelectedIndexChanged"></telerik:RadComboBox><br />        


    Each cbTaxes depends of cbTaxesGroup selection...

    And i´m using this control inside a RadGrid like:

    <telerik:GridTemplateColumn UniqueName="templateTaxesColumn" HeaderText="Impuesto">
                                    <%# Eval("TaxDescription") %>
                                    <ucCustom:ucTaxesCtrl runat="server" ID="cmbTaxes" />
                                    <asp:RequiredFieldValidator runat="server" ControlToValidate="cmbTaxes:cbTaxesGroup" CssClass="validate-control" ErrorMessage=" *" ForeColor="Red"></asp:RequiredFieldValidator>
                                    <asp:RequiredFieldValidator runat="server" ControlToValidate="cmbTaxes:cbTaxes" CssClass="validate-control" ErrorMessage=" *" ForeColor="Red"></asp:RequiredFieldValidator>

    But the problem is that the second radcombobox neves is populate...

    Someone can help me please?

    Hi Edgar,

    Attached you will find a simple implementation of the RadGrid and the User control, based on the described scenario. On our side, the User control works as expected and the second combo box gets populated appropriately.

    May I ask you to tell us how to modify the sample so it reproduces the problem? This way will will be able to troubleshoot the issue locally.
