Remember the order in which DataGridViewRows are selected?
I was wondering if it is possible to remember the order in which rows are selected. I currently have a DataGridView which is bound to a collection of items. It appea开发者_JAVA百科rs that the OnRowStateChanged fires incorrectly during the process of selecting rows using the keyboard.
Any ideas?
Edit
I am using SelectionMode.FullRowSelect, it appears that the current selection is lost during the selection of a new row.
Thanks Rohanjust verified, the first selected rows are at the end of the list:
private void button1_Click(object sender, EventArgs e)
{
for (int i = dataGridView1.SelectedRows.Count - 1; i >= 0; --i)
{
var r = dataGridView1.SelectedRows[i];
MessageBox.Show(r.Cells[0].Value.ToString());
}
}
You could capture the RowEnter and RowLeave events to track the order in which rows are visited. The argument to these handlers contains event args with the row index. In the body of the handler, you could use a linked list as a FIFO queue to follow the order in which the rows are visited.
