checking if gridview is empty using c#

Question

Currently i have the following:

if (dataGridView1.Rows.Count == 0)
{
    MessageBox.Show("EMPTY");
}
else
{
    using (var soundPlayer = new SoundPlayer(@"c:\Windows\Media\chimes.wav"))
    {
        soundPlayer.Play(); // can also use soundPlayer.PlaySync()
    }
}

My grid view looks like this:

But it seems to go to the else statement and make the sound. I need it to NOT make a sound if there is no data in the rows of the gridview.

Answer 1

According to the comment, you have:

dataGridView1.DataSource = BS;

where BS is BindingSource, so you can use its BindingSource.Count property.

So somewhere in the code:

var bindingSource = dataGridView1.DataSource as BindingSource; 
if(bindingSource.Count == 0) {
  MessageBox.Show("EMPTY");
}

You also check this when populate gridview.. like this

DataSet studentsList = students.GetAllStudents(); 
bool empty = IsEmpty(studentsList); 
if(empty) { 
MessageBox.Show("EMPTY"); 
} 
else { 
using (var soundPlayer = new SoundPlayer(@"c:\Windows\Media\chimes.wav"))
{ 
soundPlayer.Play(); 
} 
}
