I am new to datagridview. I have datagrid cellformatting event. when this event is fired e.Value is coming as null. if i bind the datasource with Bindinglist then e.Value is Null if i bind the directly with the IList, i am getting proper value.

private void Form1_Load(object sender, EventArgs e)
{
   IList<MyClass> myClassList = new List<MyClass>();
   myClassList.Add(new MyClass());
   myClassList.Add(new MyClass());

   BindingList<MyClass> myClassDS = new BindingList<MyClass>(myClassList);
   var source = new BindingSource(myClassDS, null);

   dataGridView1.DataSource = source; //e.Value is null here
   //dataGridView.DataSource = myClassList; //This is working fine
}

private void dataGridView1_CellFormatting(object sender, DataGridViewCellFormattingEventArgs e)
{
   //e.Value is null. here i should get current cell value.
}

Check the value of:

dataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex].Value
