How to get the old values

[ShahabG]

Hi
I put the grid in edit mode and getting the new values , But I want to get the old values for comparison. How do I use SavesOldValues

       If (e.CommandName = "UpdateAll") Then
            For Each editedItem As GridEditableItem In grdItemCatgLoc.EditItems

                Dim newValues As Hashtable = New Hashtable
                e.Item.OwnerTableView.ExtractValuesFromItem(newValues, editedItem)
                Dim ProductID As Long = newValues("ProductID")
'getting the old values ?????????????????????????
Dim grdDataitem As GridDataItem = e.Item.DataItem
Dim OldProductID as Long =  grdDataitem.SavedOldValues("ProductID")


editeditem.Edit=False
Next

Hello,

<MasterTableView DataKeyNames="ProductID">

if(e.CommandName = "UpdateAll")
            {
                foreach (GridEditableItem item in RadGrid1.EditItems)
                {
                    string oldProductId = item.GetDataKeyValue("ProductID").ToString(); // Get your Old Value
                    // your logic here
                }
            }

Thanks,

Hi
This is good for the key value, how about a field like ProductName which is not the GetDataKeyValue?
Thanks

Hello,

You can take multiple DataKeyNames also.
 

<MasterTableView DataKeyNames="ProductID,ProductName">
