[Solved] RadComboBox not keeping value in EditItemTemplate

[Daniel]

Hi. I've got a RadComboBox inside an EditItemTemplate that gets populated in the code behind. It needs to get populated in the code behind because the list it shows is specific to the parent table. When I perform an automatic update everything updates except this one RadComboBox. Thanks.

C#

protected void rgEnvironments_ItemDataBound(object sender, GridItemEventArgs e)
    {
        if (e.Item is GridEditableItem && e.Item.IsInEditMode && e.Item.OwnerTableView.Name != "environments")
        {
            GridDataItem dataItem = e.Item.OwnerTableView.ParentItem;
            int id = Intranet.Str2Int(dataItem.GetDataKeyValue("system_id").ToString());
            GridEditableItem moduleEdited = (GridEditableItem)e.Item;
            GridEditableItem editItem = (GridEditableItem)e.Item;
            Literal msv = (Literal)moduleEdited.FindControl("ltlModuleEdit"); // Grab selectedvalue from hidden literal
            RadComboBox moduleCombo = (RadComboBox)moduleEdited["module"].FindControl("rcbModule");
            moduleCombo.DataSource = GetModuleDataTable(id);
            moduleCombo.DataTextField = "module";
            moduleCombo.DataValueField = "module_id";
            moduleCombo.DataBind();
            if (null != msv)
                moduleCombo.SelectedValue = msv.Text;
        }
    }

ASPX

<telerik:GridTemplateColumn HeaderText="Module" UniqueName="module" HeaderStyle-Width="16%">
                                                        <ItemTemplate>
                                                            <asp:Literal ID="ltlModule" Text='<%# Bind("module") %>' runat="server" /></ItemTemplate>
                                                        <EditItemTemplate>
                                                            <asp:Literal ID="ltlModuleEdit" Text='<%# Bind("module_id") %>' Visible="false" runat="server" />
                                                            <telerik:RadComboBox ID="rcbModule" runat="server" Skin="Default" />
                                                        </EditItemTemplate>
                                                    </telerik:GridTemplateColumn>

No takers?

Hello Daniel,

 When you are performing automatic operations, the combo must point to the datasource which supplies data to the grid. When the combo is populated from the code-behind, there is no way for the data to be passed to the appropriate update parameter(s). If you would like to preserve the present setup, you can handle the whole update/delete/insert functionality from the code behind - you can intercept the newly entered values there, and propagate the changes to the database.
I hope this information helps.

Thanks for the response Yavor. That it what I thought, I was just checking if it was possible for automatic operations. Thanks again.
