Hi.

When binding to the Count property of a DataView, the bound control is not updated when applying a rowfilter to the DataView.

Sample code:

dt = new DataTable();
dt.Columns.Add("Val",typeof(int));
DataRow row;
           
row = dt.NewRow();
row["Val"]=1;
dt.Rows.Add(row);

row = dt.NewRow();
row["Val"]=2;
dt.Rows.Add(row);

row = dt.NewRow();
row["Val"]=2;
dt.Rows.Add(row);
           
textBox1.DataBindings.Add("Text",dt.DefaultView.Count,"");

****** the TextBox shows "3"

dt.DefaultView.RowFilter="Val=1";

****** the TextBox STILL shows "3"

Is this a bug or am I doing something wrong?

Surely I can do this without databinding, but I'm not looking for alternative solutions!
