C# DataGridView Check if empty

Question

I have a datagridview which gets filled with data returned from a linq query. If the query returns no results I want to display a messagebox. Is there a way of checking to see if the datagridview is empty?

Regards

Answer 1

You can find out if it is empty by checking the number of rows in the DataGridView. If myDataGridView.Rows.Count == 0 then your DataGridView is empty.

Answer 2

The DGV.Rows.Count method of checking if DGV is empty does not work if the option AllowUserToAddRows is set to true.

You have to disable AllowUserToAddRows = false then check for empty like this:

if (dataGridView1.Rows != null && dataGridView1.Rows.Count != 0)
