oldValues and newValues missing for RadComboBox in Template Fields

[Scott]

I have a form with multiple RadComboBoxes in it.  There are populated by the NeedsDataSource option.  The grid is being edited using InLine batch updating.  When the item is saved, the hash values are missing for the combobox fields unless I have opened them once while editing the record.  It seems I need to have the all populate.  How can I do that?

Hi Scott,

Please take a look at the following sample code snippet to get the RadComboBox values in batch edit:

ASPX:

<telerik:RadGrid ID="requests_grid" runat="server" Skin="Metro" AutoGenerateColumns="false" AllowSorting="true" OnNeedDataSource="requests_grid_NeedDataSource" OnBatchEditCommand="requests_grid_BatchEditCommand">
    <MasterTableView DataKeyNames="OrderID" CommandItemDisplay="Top" EditMode="Batch">
        <BatchEditingSettings EditType="Row" OpenEditingEvent="Click" />
        <Columns>
            <telerik:GridBoundColumn DataField="OrderID" HeaderText="ID" ReadOnly="true">
                <ItemStyle HorizontalAlign="Center" />
            </telerik:GridBoundColumn>
            <telerik:GridTemplateColumn HeaderText="ShipCity" UniqueName="ShipCity" DataField="ShipCity">
                <ItemTemplate>
                    <%# Eval("ShipCity")%>
                </ItemTemplate>
                <EditItemTemplate>
                    <telerik:RadTextBox runat="server" ID="txtShipCity">
                    </telerik:RadTextBox>
                </EditItemTemplate>
            </telerik:GridTemplateColumn>
            <telerik:GridTemplateColumn HeaderText="ShipCountry" UniqueName="ShipCountry" DataField="ShipCountry">
                <ItemTemplate>
                    <%# Eval("ShipCountry")%>
                </ItemTemplate>
                <EditItemTemplate>
                    <telerik:RadComboBox runat="server" ID="rcbShipCountry" EnableLoadOnDemand="true" Width="100%" MarkFirstMatch="true" OnItemsRequested="rcbShipCountry_ItemsRequested">
                    </telerik:RadComboBox>
                </EditItemTemplate>
            </telerik:GridTemplateColumn>
        </Columns>
    </MasterTableView>
</telerik:RadGrid>

C#:

protected void requests_grid_NeedDataSource(object sender, Telerik.Web.UI.GridNeedDataSourceEventArgs e)
{
    requests_grid.DataSourceID = "SqlDataSource1";
}

private void SaveRequest(GridBatchEditingCommand grdItem)
{
    Hashtable newValues = grdItem.NewValues;
    Hashtable oldValues = grdItem.OldValues;
    string id = grdItem.Item.GetDataKeyValue("OrderID").ToString();
    //getting the Updated values
    string ShipCity = newValues["ShipCity"].ToString();
    string ShipCountry = newValues["ShipCountry"].ToString();
}

protected void requests_grid_BatchEditCommand(object sender, Telerik.Web.UI.GridBatchEditingEventArgs e)
{
    try
    {
        GridDataItem grdItem;
        foreach (GridBatchEditingCommand command in e.Commands)
        {
            grdItem = command.Item;
            if (command.Type == GridBatchEditingCommandType.Update)
            {
                SaveRequest(command);
            }
        }
    }
    catch (Exception ex)
    {

    }
}
protected void rcbShipCountry_ItemsRequested(object sender, RadComboBoxItemsRequestedEventArgs e)
{
    RadComboBox ddl = (RadComboBox)sender;
    ddl.DataSourceID = "SqlDataSource2";
    ddl.DataTextField = "ShipCountry";
    ddl.DataValueField = "ShipCountry";
    ddl.DataBind();
}
