DataGridView programmatically selecting rows

using the grid we want to select an arbitrary collection of rows. Our
starting point is a collection of DataViewRow(s) from the underlying
DataView that the grid and another custom control are bound to. Having
selected the rows on our control we need to sync the grid.

We are going round in circles finding ever more tedious ways to achieve
this.

Any pointers please?

Here is a straight forward way to do it. Whether this is performant
enough will depend upon the size of the DataView you are working with.

List<DataRowView> selectedItems = new List<DataRowView>(); //holds your
selected DataRowViews
private void button1_Click(object sender, EventArgs e)
{
CurrencyManager cm =
this.dataGridView1.BindingContext[dataGridView1.DataSource,
dataGridView1.DataMember] as CurrencyManager;
DataView dv = cm.List as DataView;
int i = 0;
foreach (DataRowView drv in dv)
{
if ((selectedItems.IndexOf(drv)) > -1)
{
this.dataGridView1.Rows.Selected = true;
}
i++;
}
}

Hi Adam,

I agree to what Clay has suggested. There's no direct way but going round
in circles finding which DataGridView rows are to be selected.

I have also performed a test based on the sample code that Clay provides
and confirmed it works.

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


Sincerely,
