[Steve Ryan]

New to dot Net. i have been trying to learn how to use the new datagridview in 2005. i would like to learn how to remove a row in the dataviewgrid control. could someone please help me with this. the MS documentation showed no examples. how do i get the correct row objects to do a row delete. DataGridViewRowCollection rows = this.dataGridView1.Rows; foreach (DataGridViewRowCollection Row in rows) { // // Row.remove (?) something go here or are i the wrong track } many thanks Steve steve

Hi, The DataGridView is a visual representation of the data to which it's bound, so the best way to remove a row is to remove it from said bound data source. Also, be weary of code such as: foreach (DataGridViewRowCollection Row in rows) { // // Row.remove (?) } As you are removing something from a collection you're currently searching through.. that can get messy.

Simply...

DataGridViewRow row=dataGridView1.Rows[23];
dataGridView1.Rows.Remove(row)

Or

int index=23;
dataGridView1.Rows.RemoveAt(index)

This will physically remove the row, rather than marking it for deletion. Graham -- modified at 21:12 Tuesday 25th April, 2006
