Extracting primary key value for parent item in hierarchy on ItemDataBound

[Gino Suarez]

Hi,

Im triying to extract the primary key value for parent groupfooter item when i click on it (my gridfooteritems are links). I have two levels of groups

protected void tk_Grid_ItemDataBound(object sender, GridItemEventArgs e)
    {
    if (e.Item is GridGroupFooterItem)
        {

            GridGroupFooterItem gridfooteritem = e.Item as GridGroupFooterItem;

            if (double.Parse(gridfooteritem["Enero"].Text) == 0) gridfooteritem["Enero"].Text = "";
            gridfooteritem["Enero"].Text = "<a class=linkstotal href=frmAnexoBalance.aspx?Periodo=ENERO&MesID=1&GGPPID=0>" + gridfooteritem["Enero"].Text + "</a>";

Regards Gino

Hello Gino,

I suppose you are trying to pass the key value of the parent item as a parameter for the GridGroupFooterItem of your detail table. If so, here's an example of how to get this done:
aspx:

<telerik:RadGrid ID="RadGrid1" DataSourceID="SqlDataSource1" runat="server" OnItemDataBound="RadGrid1_ItemDataBound">
     <MasterTableView DataSourceID="SqlDataSource1" DataKeyNames="FirstName" Name="Master">
          <DetailTables>
               <telerik:GridTableView ShowGroupFooter="true" Name="Detail"  DataSourceID="SqlDataSource2" runat="server">
                   <GroupByExpressions>
                     ....
                   </GroupByExpressions>

c#:

protected void RadGrid1_ItemDataBound(object sender, Telerik.Web.UI.GridItemEventArgs e)
    {
       if (e.Item is GridGroupFooterItem && e.Item.OwnerTableView.Name == "Detail")
        {
            GridGroupFooterItem groupFooterItem = (GridGroupFooterItem)e.Item;
            GridDataItem parentItem = (GridDataItem)groupFooterItem.OwnerTableView.ParentItem;
            string strtxt = parentItem.GetDataKeyValue("FirstName").ToString();
        }
    }

Thanks
Princy.

Hi Princy, thanks for your answer, but i don`t use nested tables, i use just one table and obtaing the hierchly mode trought "outlook grouping mode". what i need no know is
 when i click on one of the groupfooter items, get the parent from this groupfooter item. thanks

<MasterTableView  CellSpacing="0" ShowGroupFooter="true" AllowMultiColumnSorting="true" ShowFooter="true">
                                            <Columns>

                                                <telerik:GridBoundColumn    DataField="Apertura" HeaderText="Apertura" Aggregate="Sum" HeaderStyle-HorizontalAlign="Right"
                                                                            FooterAggregateFormatString="{0:g}" FooterStyle-Font-Bold="true" Groupable="false">
                                                                             <HeaderStyle HorizontalAlign="Right" />
