GridDropDownColumn not working with RadAjaxManager

[Craig Wallace]

Hi,

I am building a RadGrid, which has a GridDropDownColumn in it.  I have enabled ajax on the RadGrid using the RadAjaxManager, but after I do this, the ComboBox in the GridDropDownColumn no longer drops-down, it just gets stuck and doesn't do anything when you click it.

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">
    <AjaxSettings>
        <telerik:AjaxSetting AjaxControlID="RadGrid1">
            <UpdatedControls>
                <telerik:AjaxUpdatedControl ControlID="RadGrid1" />
            </UpdatedControls>
        </telerik:AjaxSetting>
    </AjaxSettings>
</telerik:RadAjaxManager>

<asp:EntityDataSource ID="dsTypes" runat="server"
            ConnectionString="name=Entities" DefaultContainerName="Entities"
            EnableFlattening="False" EntitySetName="Types">

        </asp:EntityDataSource>
        <asp:EntityDataSource ID="dsCustomerData" runat="server"
            ConnectionString="name=Entities" DefaultContainerName="Entities"
            EnableFlattening="False" EnableUpdate="True" EnableInsert="true"
            EntitySetName="CustomerData" AutoGenerateWhereClause="True" Include="Type">

        </asp:EntityDataSource>

        <telerik:RadGrid ID="RadGrid1" runat="server"
            GridLines="None" DataSourceID="dsCustomerData"
            AutoGenerateColumns="False" AutoGenerateEditColumn="True" AutoGenerateDeleteColumn="True"
>

<MasterTableView DataSourceID="dsCustomerData" DataKeyNames="CustomerDataID">
<RowIndicatorColumn>
<HeaderStyle Width="20px"></HeaderStyle>
</RowIndicatorColumn>

<ExpandCollapseColumn>
<HeaderStyle Width="20px"></HeaderStyle>
</ExpandCollapseColumn>
    <Columns>
        <telerik:GridDropDownColumn DataField="TypeID"
            DataSourceID="dsTypes"
            HeaderText="Type" ListTextField="TypeName"
            ListValueField="TypeID" UniqueName="TypeID">
        </telerik:GridDropDownColumn>
        <telerik:GridBoundColumn DataField="Make" HeaderText="Make" UniqueName="column">
        </telerik:GridBoundColumn>
        <telerik:GridBoundColumn DataField="Model" HeaderText="Age"
            UniqueName="column1">
        </telerik:GridBoundColumn>
        <telerik:GridBoundColumn DataField="Age" HeaderText="Age" UniqueName="column2">
        </telerik:GridBoundColumn>
    </Columns>

</MasterTableView>

        </telerik:RadGrid>

If I remove the RadAjaxManager, the ComboBox works as normal.

Any ideas?

Thanks,

Craig
