You can use dataview filter in order to filter the datagrid rows.

            DataView dv = datatable.DefaultView;

            StringBuilder sb = new StringBuilder();
            foreach (DataColumn column in dv.Table.Columns)
            {
                sb.AppendFormat("[{0}] Like '%{1}%' OR ", column.ColumnName, "FilterString");
            }
            sb.Remove(sb.Length - 3, 3);
            dv.RowFilter = sb.ToString();
            dgvReports.ItemsSource = dv;
            dgvReports.Items.Refresh();

Where the "datatable" is datasource given to your datagrid and using string builder you build the filter query where "Filter String" is the text you want to search in your datagrid and set it to dataview and finally set the dataview as itemsource to your datagrid and refresh it.
