c# winform - how to delete multiple DataGridViewRows

Question

Here is m code:

foreach (DataGridViewRow r in dgv01.Rows)
       if (r.Cells[0].Value.ToString() == abc)
       {
        dgv01.Rows.Remove(r);
        //dgv01.CurrentCell = dgv01.Rows[0].Cells[0]; - also tried
        }

But only some rows are deleted - not all specified !?

Why - foreach - does not mean - foreach ?

hi you can also use RemoveAt method. try.. for(var i=0;i { DataGridViewRow r = dgv01.Rows[i] if (r.Cells[0].Value.ToString() == abc) { dgvEmployee.Rows.RemoveAt(i); } } you can also do one thing remove that row from datasource i.e data table or collection. Examle if you data set to bind datagrid then Dataset dataset = dgv01.DataSource as Dataset; for(var i=0;i { DataRow r = dataset.Tables[Employees].Rows[i] if (r.Cells[0].ToString() == abc) { dataset.Tables[Employees].Rows[i].Delete(); } } hope this will help u.

Jignesh thanks aLot. I just replaced your loop by an reverse loop and - it works: for (int i = dgv01.Rows.Count - 1; i >= 0; i--) ThanksAgain!
