    When i try to delete selected row, sometimes i got this error:

    Error:

    An unhandled exception of type ‘System.InvalidOperationException’ occurred in Xceed.Grid.dll

    Additional information: An attempt was made to create a cell when its parent row is not part of a grid.

    And this is my codes for deleted selected row:

    For i As Integer = GridControl1.SelectedRows.Count – 1 To 0 Step -1
    GridControl1.SelectedRows(i).Remove()
    Next

    i bind the grid to the dataset(the dataset’s data was filled from access database(JET 4.0) ) , can someone give me the solution?

    I don’t know if this would work, but call GridControl1.BeginInit() before removing the rows and GridControl1.EndInit() after removing.

    Your code is wrong.

    Try this instead:
    IF GridControl1.SelectedRows.Count > 0 then
    . . . For I as integer = GridControl1.SelectedRows.Count to 1 Step -1
    . . . . . . GridControl1.SelectedRows(I – 1).Remove
    . . . Next
    End If
