Hi Michele,

Please check out the following demo which resembles your scenario and try to distinguish the crucial differences between the demo and your own projects:
http://demos.telerik.com/aspnet-ajax/grid/examples/dataediting/usercontroleditform/defaultcs.aspx

In addition, you could also refer to the topic below:
http://www.telerik.com/help/aspnet-ajax/ajax-user-controls.html

I hope this will prove helpful.

Kind regards,

Thanks for the reply, the difference between the demo and my plan is to use a user control within EditFormSettings only two combobox.
Below I write my example:
<EditFormSettings EditFormType="Template">
<EditColumn FilterControlAltText="Filter EditCommandColumn column"></EditColumn>
    <FormTemplate>
        <fieldset>
            <legend>xxxxxxxxxxxxxxxxxxxx</legend>
        <table style="padding: 5px; margin: 2px; width:900px;" border="0">
            <tr>
                <td style="width:150px;"><asp:Label ID="Label10" runat="server" Text="xxxxxxxxxxxxxxxx: " /></td>
                <td>
                    <telerik:RadTextBox ID="RadTextBox2" runat="server"
                        EmptyMessage="xxxxxxxxxxxxx..." Text='<%# Eval("Cod")%>' Enabled="false">
                    </telerik:RadTextBox>
                </td>
                <td style="width:150px; text-align: right;"><asp:Label ID="Label11" runat="server" Text="xxxxxxxxx: " /></td>
                <td><telerik:RadTextBox ID="RadTextBox3" runat="server"  ShowButton="True" Width="90%"
                        EnableSingleInputRendering="true" EmptyMessage="type here..." Text='<%# Bind("ModelName")%>'>
                    </telerik:RadTextBox>
                </td>
            </tr>
 
                    <uc2:ComboCatArt runat="server" ID="ComboCatArt" />
 
            <tr>
                <td colspan="4"><asp:Label ID="Label3" runat="server" Text="xxxxxxxxxxxxx " /></td>
            </tr>

the <uc2:ComboCatArt... not work in RadAjaxManager, work only 

RadAjaxManagerProxy

Hello Michele,

I have created a sample RadGrid web site using the provided code snippet. On my side everything works as expected and the grid is being successfully ajaxified. Please check out the attached application and let me know if I am missing something out to reproduce the issue.

your example works fine, but the problem is in the usercontrol.
I've modified your example putting my usercontrol, so you can see the problem.
Thank you for your interest.
I wanted to add that the project error but the forum will not let me attach a file. rar
I am attaching the code of my usercontrol I would ask you to replace the one you put in the example



<%@ Control Language="C#" AutoEventWireup="true" CodeFile="ComboCatArt.ascx.cs" Inherits="ComboCatArt" %>
 
        <tr>
            <td style="width:150px;"><asp:Label ID="Label1" runat="server" AssociatedControlID="RadComboBox1" Text="xxxxxxxxxxxxxxx:"></asp:Label></td>

                <telerik:RadComboBox ID="RadComboBox1" runat="server" Width="90%" CssClass="ComboBox_Continents"
                    OnClientSelectedIndexChanging="LoadCountries" OnItemsRequested="RadComboBox1_ItemsRequested" EmptyMessage="... xxxxxxxxxxxxx ...">
                </telerik:RadComboBox>
            </td>
            <td style="width:150px; text-align: right;">

Hello Michele,

Please note that when you are using RadAjax, you will need to wrap any JavaScript code in RadScriptBlock as suggested in the following article?
http://www.telerik.com/help/aspnet-ajax/ajax-radscriptblock-radcodeblock.html

I have tried the suggested solution and it works as expected on my side.
