How can get the height of vertical scrolling bar of GridDataBoundGrid

[Len Tran]

Hi,
I would like to have a height of vertical scrolling bar of GridDataBoundGrid to make the page number when the GridDataBoundGrid has lot of rows.

The draft code is:
pageNumber = heightOfGridDataBoundGrid/ heightOfVerticalScrollingBar

When the height of GridDataBoundGrid is changed then the page number is also changed

Thanks for your support!

I am not sure this will allow you to do what you want.

The height of all scrollable rows in the grid is:

int heightAllRows = grid.Model.RowHeights.GetTotal(grid.Model.Rows.HeaderCount + 1, grid.Model.RowCount);

The height of the scrollable client area is

int heightOfScrollableClientArea = grid.ClientSize.Height - grid.Model.RowHeights.GetTotal(0, grid.Model.Rows.HeaderCount);

But unless you are assuming all rows have equal heights, and that the grid is always sized so only an integral number of rows are vivible, I am not sure how your calcualtion will work.

Some other calcualtions and properties you may want to consider using:

grid.TopRowIndex - gets or sets the top scroallable row in the grid
grid.ViewLayout.LastVisibleRowIndex - last visible row in the grid (may or may not be partially visible - check grid.ViewLayout.HasPartialVisibleRows to see)

Thank you!
Another questions:

1) I would like to display the number of each page on label when croll is changed the position. How can I do that with the formula above?.
Example: page 1 of 15, .... page 2 of 15 etc

2) What is the event of GridDataBoudGrid when I adjust the height of GridDataBoudGrid by mouse(at the bottom of GridDataBoundGrid)

Thanks for your help!
