           Summary: rowCount / Rows.Count is 0 after

I habe a DataGridView. When I assign a BindingSource (List<object> as
DataSource) to the DataGridView and I print out the RowCount I get 0. The
DataGridView fills the Columns/Rows with the Data.

e.g

List<string> dataList = new List<string>();

dataList.Add("string 1");
dataList.Add("string 2");
dataList.Add("string 3");
dataList.Add("string 4");
dataList.Add("string 5");


BindingSource bs = new BindingSource();
bs.DataSource = dataList;

DataGridView dgv = new DataGridView();
dgv.DataSource = bs; // assign binding source to datagridview

Console.WriteLine("rows:" + dgv.RowCount); // here I get 0 but the DataGridView
hast 1 Column and 5 Rows (with "string1", ...)

I also tried to create my own DataGridView. When I override the OnPaint Method,
then the RowCount is 5. When I override the OnDataSourceChanged Method the
RowCount is 0.




Reproducible: Always

Steps to Reproduce:
1. Add BindingSource to DataGridView
2. Print out RowCount or Rows.Count (of the DataGridView)
3.


Expected Results:  
RowCount / Rows.Count should not be 0 after assigning a DataSource (>0 items)
