    How to make the datagrid view not hightlight the first row?

    When you retrieve records to diplay in a DataGridView control the first
    record has the background highlighted even though no row is yet selected.
    Does anyone know a way to suppress this first record highlighting after
    pulling the records into the grid?

      Your description isn't quite correct. The first row is in fact
      selected - if you look at DataGridView.Se lectedRows you should see the
      first row in the list.

      I don't know of any way to prevent the first row from being selected.
      You have to arrange to unselect it after the DataGridView selects it.

      If the datagridview is visible at the time you set it's DataSource,
      then calling DataGridView.Cl earSelection() immediately after setting
      the DataSource will most likely work.

      If you are setting the DataSource during the construction of a form
      before the Load event fires, then you may have to call ClearSelection
      later, perhaps in the Form.Load event.

          The problem I see it that the little chevron doesn't show to the left of the
          highlighted row. It is highlighted but until that chevron is there if you
          try to reference the data set in that row it errors out. I can't seem to
          test for it either.

              I am not sure how you "test for it".

              The DataGridView has two separate things, selected rows (the
              SelectedRows collection) and CurrentRow, the current row. The marker
              in the row header (the left-most column) marks the current row. You
              can change which row is current by setting the CurrentCell property to
              a cell in the row you wish to make current.

              I don't understand what you mean by "if you try to reference the data
              set in that row it errors out". If you get an error, please always
              say what the error is. How are you trying to reference the data?

                  Before testing try


                  IsNothing(MyDat aGridView.Curre ntRow)



                  This should at least stop u from accessing a row that is not valid at the
                  current moment in time.
