Move rad gridview data up and down

[Mohan]

Hi,
I have a gridview loaded with a datatable.  I have 2 buttons "Up" and "Down" outside the grid.  The "Up" button takes the selected row and moves it up one row.  The "Down" button takes the selected row down a row. 

eg:
1  sample1
2  sample2
if selected row is sample1 and then i click down button, i need to change the grid row to
2 sample2
1  sample1

please give solution for this

Hi,

I got Solution.

public static void MoveRowUp(BindingSource sender)
        {
            if (!(string.IsNullOrWhiteSpace(sender.Sort)))
                sender.Sort = "";
            int NewIndex = Convert.ToInt32((sender.Position == 0) ? 0 : sender.Position - 1);
            var dt = (DataTable)sender.DataSource;
            DataRow RowToMove = ((DataRowView)sender.Current).Row;
            DataRow NewRow = dt.NewRow();
            NewRow.ItemArray = RowToMove.ItemArray;
            dt.Rows.RemoveAt(sender.Position);
            dt.Rows.InsertAt(NewRow, NewIndex);
            dt.AcceptChanges();
            sender.Position = NewIndex;
        }
        public static void MoveRowDown(BindingSource sender)
        {
            if (!(string.IsNullOrWhiteSpace(sender.Sort)))
                sender.Sort = "";
            int UpperLimit = sender.Count - 1;
            int NewIndex = Convert.ToInt32((sender.Position + 1 >= UpperLimit) ? UpperLimit : sender.Position + 1);
            var dt = (DataTable)sender.DataSource;
            DataRow RowToMove = ((DataRowView)sender.Current).Row;
            DataRow NewRow = dt.NewRow();
            NewRow.ItemArray = RowToMove.ItemArray;
            dt.Rows.RemoveAt(sender.Position);
            dt.Rows.InsertAt(NewRow, NewIndex);
            dt.AcceptChanges();
            sender.Position = NewIndex;
        }

 

Here I am binding data into RadGridView.Then passing binding source to the function.

Hello guys, 

Thank you for writing.  

In order to reorder the rows in RadGridView, it is necessary to reorder the records in the DataSource accordingly. A sample approach is demonstrated in the following help article using the drag and drop behavior: http://docs.telerik.com/devtools/winforms/gridview/rows/drag-and-drop
You can use a similar approach for achieving the same functionality with buttons.

@Abdul, I have updated your Telerik points for the shared solution.

I hope this information helps. Should you have further questions I would be glad to help.
