Why don't you build a DataTable first then assign it to the DataGridView as DataSource:

DataTable table4DataSource=new DataTable();

table4DataSource.Columns.Add("col00");
table4DataSource.Columns.Add("col01");
table4DataSource.Columns.Add("col02");

...

(add your rows, manually, in a circle or via a DataReader from a database table) (assign the datasource)

dtGrdViewGrid.DataSource = table4DataSource;

and then use:

(dtGrdViewGrid.DataSource as DataTable).DefaultView.RowFilter = "col00 = '" + textBoxSearch.Text+ "'";
dtGrdViewGrid.Refresh();

You can even put this piece of code within your textbox_textchange event and your filtered values will be showing as you write.
