DevExpress控件之RepositoryItemComboBox

RepositoryItemComboBox在嵌入到GridView后，如何获取当前所选的Item？

直接代码：

 ((RepositoryItemComboBox)gridView.Columns["ColName"].ColumnEdit).SelectedIndexChanged += new System.EventHandler(ColName_SelectedIndexChanged);
 2
 private void ColName_SelectedIndexChanged(object sender, System.EventArgs e)
 {

 　　　//获取所选item的索引
      int i = ((DevExpress.XtraEditors.ComboBoxEdit)sender).SelectedIndex;
 　　　//获取所选item的内容
 　　　string currentItem=((DevExpress.XtraEditors.ComboBoxEdit)sender).EditValue.ToString();
 }
