DataGridView row selection

[Lennart]

Hi

I have a DataGridView on a Form filled with data from a DataTable. When I
Load this form I want to select a row in the DataGridView depending on a
selected Primary Key index;

How do I do this?

Hi Lennart,

I'm not exactly sure what you are asking, but here is some code that will
select the row of the DataGridView that is bound to a DataRow with a
specific primary key value:

int primaryKey = 5;

// assuming dataGridView1 is bound to dataTable
int rowIndex = dataTable.Rows.IndexOf(dataTable.Rows.Find(primaryKey));

dataGridView1.Rows[rowIndex].Selected = true;

You can replace "dataTable.Rows" with "dataView" in the above code if
dataView is a DataView to which the DataGridView is bound instead of
dataTable.

Hi Dave

You put me on the right track, but the correct way turned out to be this.

dataGridView1.FirstDisplayedScrollingRowIndex =
myTable.Rows.IndexOf(myTable.Rows.Find(myIndex));

dataGridView1.CurrentCell = dataGridView1.FirstDisplayedCell;
