I have this code in my C# program, but it throws a fit when some buttons are clicked because there is no row selected in the DataGridView (I use the ClearSelection method):
string selectedUser = usersGrid.SelectedRows[0].Cells[1].Value.ToString();
Is there some sort of check I can do before the above line to ensure that a row is selected?
if (usersGrid.SelectedRows.Count > 0)
I am going to take a stab at what I think you are trying to do, try this below
private void myButton_Click(object sender, EventArgs e)
{
foreach (DataGridViewRow row in usersGrid.Rows)
{
if (this.usersGrid.SelectedRows.Count == 1)
{
// get information of 1st column from the row
string selectedUser = this.usersGrid.SelectedRows[0].Cells[0].ToString();
}
}
}
also do the following as well and checkout the link
Set DataGridView.MultiSelect =false and DataGridView.SelectionMode = FullRowSelect. This will make it so the user can only select a single row at a time.
