oleDbDataAdapter.Fill(ds, tblName);
gridControl1.DataSource = ds.Tables[tblName];
gridControl1.MainView.PopulateColumns();
}
//可以添加自定义EmbededNavigator的CustomButtons：
this.efDevGridOth.EmbeddedNavigator.Buttons.CustomButtons.AddRange(newNavigatorCustomButton[] {
new NavigatorCustomButton(5, "保存"),
new NavigatorCustomButton(6, "返回")
});
//设置Grid的Style，对应行的新增/修改状态：
private void gridView1_RowStyle(objectsender, RowStyleEventArgs e)

try
{
if(this.gridView1.DataRowCount < 1) return;
if(e.RowHandle < 0)
