I have a button that does an operation. but if my datgridview is empty or null it will prom a message saying it is null or empty.

What I have tried:

if (mydatagridview.rows.count == 0)
{
//message
}
but this is checking every row that I have what if I have tons of rows.is there other way for faster logic/code than this? thankss

To check for null and empty:

if (mydatagridview == null || mydatagridview.Rows.Count == 0)
{
    // message
}

Rows.Count doesn't calculate the rows at the time of calling, but returns a value that is updated when adding and deleting rows. There is no problem calling it to check if the DataGridView is empty.
