Programmatically change selection on DatagridView (.NET)

Question

Hi,

I'm learning VB.NET.

I've a problem with DataGridView component when trying to set the value of the CurrentCell. What i'm trying to do is :

I've a DataGridView With values. I want to make a button in my forms and when clicking on it I want to change the selection from the current row to the next. To explain more, by clicking my Button I want to simulate the effect of a mouse click on a DataGridview.

I hope you can help me,

Thanks!

Answer 1

You need to set the particular row's Selected property to true. I think the VB would be something like this:

someDGV.Rows(index).Selected = True

Answer 2

You could do it this way:

If DataGridView1.CurrentRow.Index < DataGridView1.Rows.Count Then
    DataGridView1.Rows(DataGridView1.CurrentRow.Index + 1).Selected = True
End If

Answer 3

Maybe something like this:

    If DataGridView1.RowCount > 0 Then

        Dim MyDesiredIndex As Integer = 0

        If DataGridView1.CurrentRow.Index < DataGridView1.RowCount - 1 Then
            MyDesiredIndex = DataGridView1.CurrentRow.Index + 1
        End If

        DataGridView1.ClearSelection()            
        DataGridView1.CurrentCell = DataGridView1.Rows(MyDesiredIndex).Cells(0)
        DataGridView1.Rows(MyDesiredIndex).Selected = True

    End If

Note 1: maybe these two lines are not necessary. I haven´t proved it

        DataGridView1.ClearSelection()            
        DataGridView1.CurrentCell = DataGridView1.Rows(MyDesiredIndex).Cells(0)

Note 2: note that if we are in the last row, it goes to first
