Accessing parent grid dataKeys

[Borislava]

I have radGrid1 and inside radGrid1  pageView and Tabs with 2 more radGrid2 and ragGrid3.
In edit mode radGrid2 and radGrid3 shown.
in radGrid2  and radGrid3 users can add new items however I ran into the issue where I can't get the keys from radGrid1 .
Could you help me?

Hello,

<telerik:RadGrid ID="RadGrid1" runat="server" OnNeedDataSource="RadGrid1_NeedDataSource"
    AllowPaging="true" OnItemCommand="RadGrid1_ItemCommand">
    <MasterTableView DataKeyNames="CustomerID">
        <NestedViewTemplate>
            <asp:Panel runat="server" ID="Panel1" Visible="true">
                <telerik:RadTabStrip runat="server" ID="TabStrip1" MultiPageID="Multipage1" SelectedIndex="0">
                    <Tabs>
                        <telerik:RadTab runat="server" Text="Page 1" PageViewID="PageView1">
                        </telerik:RadTab>
                    </Tabs>
                </telerik:RadTabStrip>
                <telerik:RadMultiPage runat="server" ID="Multipage1" SelectedIndex="0" RenderSelectedPageOnly="false">
                    <telerik:RadPageView runat="server" ID="PageView1">
                        <telerik:RadGrid ID="RadGrid2" runat="server" AllowPaging="true" PageSize="5" OnNeedDataSource="RadGrid2_NeedDataSource" />
                    </telerik:RadPageView>
                </telerik:RadMultiPage>
            </asp:Panel>
        </NestedViewTemplate>
    </MasterTableView>
</telerik:RadGrid>

protected void RadGrid1_NeedDataSource(object sender, GridNeedDataSourceEventArgs e)
  {
      RadGrid1.DataSource = "YourDataSOurce";
  }
  protected void RadGrid2_NeedDataSource(object sender, Telerik.Web.UI.GridNeedDataSourceEventArgs e)
  {
     GridDataItem parentItem = ((sender as RadGrid).NamingContainer as GridNestedViewItem).ParentItem as GridDataItem;
        string strID = parentItem.GetDataKeyValue("ID").ToString();
        //Access your Key here
       (sender as RadGrid).DataSource = "YourDataSource";
  }
  protected void RadGrid1_ItemCommand(object sender, GridCommandEventArgs e)
  {
      if (e.CommandName == RadGrid.ExpandCollapseCommandName && !e.Item.Expanded)
      {
          GridDataItem parentItem = e.Item as GridDataItem;
          RadGrid grid = parentItem.ChildItem.FindControl("RadGrid2") as RadGrid;
          grid.Rebind();
      }
  }

Hi,

Please try the following code snippet to access the DataKeyValue of the parent-table in the Inner Radgrid.

C#:

protected void RadGrid2_InsertCommand(object sender, GridCommandEventArgs e)
{
    if (e.Item is GridEditableItem)
    {
        GridEditFormInsertItem insertItem = e.Item as GridEditFormInsertItem;
        RadGrid innergrid = (RadGrid)insertItem.OwnerTableView.OwnerGrid;
        GridNestedViewItem nestedItem = (GridNestedViewItem)innergrid.NamingContainer;
        GridDataItem parentitem = (GridDataItem)nestedItem.ParentItem;
        string value= parentitem.GetDataKeyValue("DataKeyColumnName").ToString();// Access Parent table DtakeyValue
    }
}

Thanks,
Princy
