What's the best way to change the current record selected on a DatagridView
control using code in VB.NET 2005/C#.NET 2005?

Thanks,

Victor
 
For what purpose? In what way? YOu mean instead of having the user
do it, or you mean ways for the user to do it?

If you are using databinding, and you use a bindingsource between your
data and your datagridview, you could do a myBindingSource.Position=3
or something like that, and move next/previous/last/first.

You can also use a BindingNavigator to move amongst the records.

Does that help at all?

Hi Victor,

In a DataGridView, the selected row and the current row (indicated by an
arrow in the row header) may not be the same row. In addition, we could
select multiple rows in a DataGridView but the current row can only be one
row.

When the SelectionMode property of the DataGridView is set to
FullRowSelect, the current row will be always selected.

If you'd like to change the current row in a DataGridView control, you may
set the CurrentCell property. The following is a sample.

(change the current row to the row with index of 1)
VB.net:
DataGridView1.CurrentCell = DataGridView1.Rows(1).Cells(0)
C#:
dataGridView1.CurrentCell = dataGridView1.Rows[1].Cells[0];

If you'd like to just change the selected row, you may set the Selected
property of the row you want to true. The following is a sample.

(change the selected row to the row with index of 1)
VB.net:
DataGridView1.CurrentRow.Selected = False
DataGridView1.Rows(1).Selected = True
C#:
dataGridView1.CurrentRow.Selected = false;
dataGridView1.Rows[1].Selected = true;

Hope this helps.
If you have anything unclear, please feel free to let me know.


Sincerely,
Linda Liu

Hi Linda:

There needs to be a better mechanism than this. It will not work when
column 0 is not visible. I am now faced with iterating through the
columns to find one that is visible. Not a pretty solution,
particularly for such a simple task.

Thank you.
 
if you're using full row select you can do this:

'Find selected row, in case you need to know it
Dim i As Integer
i = dgHistory.SelectedRows.Item(0).Index

'set new selected row
dgHistory.CurrentRow.Selected = False
dgHistory.Rows(5).Selected = True
