C#模糊查询绑定datagridview

PRivate CollectionViewSource wgdData = new CollectionViewSource();

private DataTable Ds_wgd { get { return this.dgv_wgd.ItemsSource as DataTable; } set { wgdData.Source = value; this.dgv_wgd.ItemsSource = ((DataTable)wgdData.Source).DefaultView; } }

//文本框修改后，直接会修改

private void txt_jkshm_TextChanged(object sender, TextChangedEventArgs e) { (this.wgdData.Source as DataTable).DefaultView.RowFilter = "jkshm like '%" + this.txt_jkshm.Text.Trim() + "%' "; }
