I have the following telerik grid and need to pass the data value from the nested table into the ItemCommand so when
the user clicks the grid button the code is executed I am stuck on where to go with this

<telerik:RadGrid ID="grdRegions" runat="server" Skin="Metro" AllowCustomSorting="True"
                ShowHeader="True" PageSize="10" ShowGroupPanel="False"     OnItemCommand="grdRegions_ItemCommand"

Hi Jeff,

You can access the item as well as the parent item of the clicked button container:
<telerik:GridTableView ... Name="Orders">
C#:
protected void RadGrid1_ItemCommand(object sender, GridCommandEventArgs e)
{
    if (e.Item.OwnerTableView.Name == "Orders" && e.Item is GridDataItem)
    {
        GridDataItem dataItem = e.Item as GridDataItem;
        string dataKeyID = dataItem.GetDataKeyValue("OrderID").ToString();
 
        GridNestedViewItem nestedViewItem = dataItem.OwnerTableView.NamingContainer as GridNestedViewItem;
        GridDataItem parentItem = nestedViewItem.ParentItem as GridDataItem;
        string parentDataKeyID = parentItem.GetDataKeyValue("CustomerID").ToString();
    }
}

Additionally, you can refer to this article for accessing the cell contents of the item:
http://www.telerik.com/help/aspnet-ajax/grid-accessing-cells-and-rows.html

Hope this helps.

All the best,
Eyup

Hi,

I have a radgrid with 3 levels of hierarchy. I am doing a programming binding using NeedDataSource and DetailsTableBind events. 

I want to get all data at once and bind it so that I don't go to the database each time the expand is clicked on each level. Right now, I am not sure how to go about it. Attached the code.



<telerik:RadGrid ID="gridComplianceSummary" runat="server" AutoGenerateColumns="false"

Hi Sumathi,

You can use the ServerBind or Client load mode to achieve this requirement:
