In the radgrid, i am using editmode = inplace.
sample aspx for edititemtemplate is:
                      <telerik:RadTextBox ID="RadtxtPrdNumber" runat="server" Text='<%# Eval("ProductNumber") %>'>

In the updateCommand code i have the below:
GridEditableItem editedItem = (GridEditableItem)e.Item;
                string value = editedItem.OwnerTableView.DataKeyValues[editedItem.ItemIndex]["ProductNumber"].ToString();
                DataTable ordersTable = this.OrderGridData;
                //Locate the changed row in the DataSource 
                string filter = "ProductNumber = '" + value + "'";
                DataRow[] changedRows = ordersTable.Select(filter);
        Hashtable newValues = new Hashtable();
                //The GridTableView will fill the values from all editable columns in the hash 
                // in the below code newvalues is coming as empty 
                e.Item.OwnerTableView.ExtractValuesFromItem(newValues, editedItem);
                DataRow changedRow = changedRows[0];

The bolded line has newvalues as empty. i have changed few columns. How to retrieve the updated items?

Hello Venkatesh,

In order to achieve your scenario you should manually retrieve the RadtxtPrdNumber control value as shown below.
RadTextBox number = e.Item.FindControl("RadtxtPrdNumber") as RadTextBox;
string value = number.Text;

Note that the experienced behavior is expected. When using templates RadGrid ExtractValuesFromItem could not extract the values because it is unaware of which control value to extract. For example there could be multiple controls in the EditItemTemplate.

Kind regards,
