Hello Guys,

I have a opposite situation. I have a form and it contains UltrawinGrid. When the grid is loaded with data. It is selecting a row in the somewhere middle on the grid by default. I dont want any row to be selected in the grid by default.

Let me know how can i do this?

Thanks,

Mayank

Hi Mike,

thank you very much.

That is exactly what I was looking for. I tested it and I couldn't find problems.

After sorting the Grids Column, I just called your Method ScrollRowToMiddle(ultraGrid1.ActiveRow).

Lot's of greetings from Germany.

Hi Nobbi,

There's no method in the grid to scroll a row into the exact middle. The only way to scroll to a specific position in the grid it so set the FirstRow property of the ActiveRowScrollRegion. So if you know what row you want to be in the middle and you know how many rows fit in the grid's display, you could find a row that is a few rows up from the one you want in the middle and make it the FirstRow. But how you do this will depend on lot on other factors and assumptions you can make in your application.

For example, if the row in question is the first row in the grid, then you cannot scroll it to the middle.

Here's some quick sample code I whipped up. It is by no means complete - it does not handle every case, but it should point you in the right direction.

        private void ScrollRowToMiddle(UltraGridRow row)

        {

            UltraGrid grid = (UltraGrid)row.Band.Layout.Grid;

            UIElement gridElement = grid.DisplayLayout.UIElement;

            if (gridElement == null)

                return;



            UIElement rowColRegionIntersectionUIElement = gridElement.GetDescendant(typeof(RowColRegionIntersectionUIElement));

            if (rowColRegionIntersectionUIElement == null)

                return;



            // Determine the total number of rows that can fit in the visible

            // area of the grid. We are assuming that the Rows are all the same height.

            int visibleRows = rowColRegionIntersectionUIElement.Rect.Height / row.Height;



            // Find the row that is half the visibleRows prior to the row we want.             

            //

            UltraGridRow newFirstRow = row;

            int rowOffset = visibleRows / 2;

            for (int i = 0; i < rowOffset; i++)

            {

                if (newFirstRow.HasPrevSibling(false, true))

                    newFirstRow = newFirstRow.GetSibling(SiblingRow.Previous, false, true);                    

            }



            // Set the new FirstRow. 

            grid.ActiveRowScrollRegion.FirstRow = newFirstRow;

        }
