My dataview consists of data from datatable
applying filter on dataview want to apply case sensitive to dataview


My code is


DataView dvTemp = dtFilter.Copy().DefaultView;

dvTemp.RowFilter = "PAR_TEXT = '" + _par + "'";
DataTable dtTemp = dvTemp.ToTable();
if (dtTemp != null)
{
if (dtTemp.Rows.Count > 0)
{
intPARID = Convert.ToInt32(dtTemp.Rows[0][3]);
}
}
Which will give row even case match or not

any suggestions
