I am new to .NET and have acquired a project that I am having trouble with. My main question is regarding DataGrids and the selected index Property. The app displays a datagrid with numerica paging. There is a button which allows you to select a specific row, which displays more information about the data in that row. It can also add new rows and delete rows from the database. The problems I am encountering are with the SelectedIndex property and the CurrentPageIndex when adding and deleting rows.
For example, If I am on page 4 and there are 1 record, and I delete it, the SelectedIndex should go to the previous record, now on page 3. Has anyone encountered this? Or can point me to a resource with some good example code. I really can't paste the code here because I am still trying to figure it out and there is too much. Thanks for any help.........

After deleting the row from the table:
MyDataGrid.SelectedIndex = MyDataGrid.SelectedIndex - 1
MyDatGrid.PageIndex = CType( Math.Ceiling( MyDataGrid.SelectedIndex / NumRowsPerPage ), "Int32" ) - 1
That should select the right page for you. You may need to add a special check for page 0 (the first page) or selectedindex 0 (the first row), and one for an empty table (the last row was deleted) where you don't have any selected index.
