I am trying to make the drag and drop from a tree view put the dragged content into the appropriate section of a hierarchical grid (adjacent to the row it was dropped on).

I am capturing the itemIndexHierarchical of a row in the OnRowMouseOver event on the client.  I am saving this in a hidden field so that I can look up the row in some server code (the event handler for the tree view drop event). 

How can I get the row and or dataKeyValues given the itemIndexHierarchical key?  Surely there is a server side call that can do this for me, am I missing something?

Thanks,
Kenny Long

Hello,

Each GridItem also has an ItemIndexHierarchical property on the server which you can use the find the corresponding item on the server-side. You can iterate through the Items collection of the control and see which one matches the saved hierarchical item index value from the client.

Thanks for the response Martin, is there a sample of how to iterate through the items in a Heirarchical grid?  Also, what is the property in the grid that holds the ItemIndexHierarchical value.

Thanks in advance!

Hi Martin, a little poking around and I figured it out.  I am including the code snippet here to help someone else who may need this:

            if (e.HtmlElementID == RadGrid1.ClientID)
            {

                foreach (GridDataItem item in RadGrid1.MasterTableView.ItemsHierarchy)
                {
                    String s = item.ItemIndexHierarchical;
                    if (s.Equals(gridDropIndex))
                    {
                        String key = item.KeyValues;
                    }
                }
