Hi,

There's no functionality for auto-fill built into the grid. But you could implement this yourself very easily.

What I would do is set up the grid to allow selecting ranges of cell. You do this using grid.DisplayLayout.Override.SelectTypeCell and also the CellClickAction property.

Then you could use the grid's MouseUp event and trap for a right-click on the selected cells and give the user a context menu to auto-fill. Or you could use a button or a toolbar button or whatever UI you like to trigger the auto-fill.

To perform the fill operation, you would do something like this:

            SelectedCellsCollection selectedCells = this.ultraGrid1.Selected.Cells;
            if (selectedCells.Count < 2)
                return;
            
            // It would probably be a good idea to verify that all of the selected cells 
            // belong to the same column here. Alternately, this could also be enforced using the 
            // BeforeSelectChange event. 

            // Sort the selected cells in the visible order
            selectedCells.Sort();

            // We are assuming the column is an integer
            int value = (int)selectedCells[0].Value;

            for (int index = 1; index < selectedCells.Count; index++)
            {
                value++;
                selectedCells[index].Value = value;
            }
