Not able to get the changed values in update command

[Venkatesh]

HI,
I am using the RAD Grid in sharepoint 2010.
I have the following code in the update command:

protected void RadGrid1_UpdateCommand(object sender, GridCommandEventArgs e)
        {

            GridEditableItem editedItem = e.Item as GridEditableItem;
            DataTable ordersTable = this.GridData;

            //Locate the changed row in the DataSource

            string filter = "Title = '" + Convert.ToString(editedItem.OwnerTableView.DataKeyValues[e.Item.ItemIndex]["Title"]) + "'";

//  here Title='1' is shown. 1 is the value which is changed to 2.

            DataRow[] changedRows = ordersTable.Select(filter);

            if (changedRows.Length != 1)
            {
                RadGrid1.Controls.Add(new LiteralControl("Unable to locate the Order for updating."));
                e.Canceled = true;
                return;
            }

            //Update new values
            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];
            changedRow.BeginEdit();
            try
            {
                foreach (DictionaryEntry entry in newValues)
                {
                    changedRow[(string)entry.Key] = entry.Value;
                }
                changedRow.EndEdit();
            }
            catch (Exception ex)
            {
                changedRow.CancelEdit();
                RadGrid1.Controls.Add(new LiteralControl("Unable to update Orders. Reason: " + ex.Message));
                e.Canceled = true;
            }
            ordersTable.AcceptChanges();

            this.GridData = ordersTable;
            RadGrid1.DataBind();
        }

How to get the changed values?
Thanks

Hello Venkatesh,

Thank you for contacting us.

Your update command is perfectly all right except for the last statement (RadGrid1.DataBind() ) which should be removed since the grid will rebind itself automatically upon the update command handler having been executed. In addition, do make sure that you are using Advanced data-binding for your grid as opposed to Simple data-binding.

If, however, this does not help, I'd ask you to send your complete implementation as a file attachment.

HI,
Thanks for the reply.
i have removed the databind last statement.
However, i am not getting the changed values. Below line is giving empty.

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);

Hello Venkatesh,

I understand but I need your complete code since the information provided is not sufficient to reveal the cause for the problem. It'd be even greater if you make it a runnable sample. Thanks for that.
