Master/Detail Parent ID

[Pouya ir]

hi
i have 3 table:  1- Master table    2- Detail table(0)    3- Detail table(1)
when i want update detailTable(0) i can:

int ParentId = RadGrid1.MasterTableView.DataKeyValues[

int.Parse(e.Item.OwnerTableView.ParentItem.ItemIndexHierarchical)]["Id"].ToString();

but when i want update DetailTable(1) i can not use this code :

 

int ParentId = RadGrid1.MasterTableView.DetailTables[0].DataKeyValues[int.Parse(e.Item.OwnerTableView.ParentItem.ItemIndexHierarchical)][

"Id"].ToString();
    // erro ocured and i can not use :((

maybe my method completly is uncurrect.

Hello,

Check out the following code that I tried to retrieve the DataKeyValues for the third level's parnet item in a hierarchial grid:
c#:

string ParentId = item.OwnerTableView.ParentItem.GetDataKeyValue("Id").ToString();

Hope this helps... :)

How do I grab this parent ID and put in a textbox in editmode of the detail table?

Hello Illumination,

Try the following code snippet in ItemDataBound event to get the parent ID in edit mode. Hope this helps.

C#:

protected void RadGrid2_ItemDataBound(object sender, GridItemEventArgs e)
   {
       if (e.Item is GridEditableItem && e.Item.IsInEditMode && e.Item.OwnerTableView.Name == "DetailTable1")
       {
           GridEditableItem item = (GridEditableItem)e.Item;
           string customerId1 = item.OwnerTableView.ParentItem.GetDataKeyValue("ID").ToString();
           TextBox txtbox = (TextBox)item["temp"].FindControl("txt");
           txtbox.Text = customerId1;
       }
   }

Thanks,
Princy.
