DevExpress gridcontrol添加了复选框删除选中的多行/批量删除的方法

public void DoDelete()
{

for (int i = 0; i < gridView1.DataRowCount; i++)
{
if (gridView1.GetDataRow(i)["checked"].ToString().Trim().ToLower() == "true")
{
gridView1.SelectRow(i);
}
else
{
gridView1.UnselectRow(i);
continue;
}

}

this.gridView1.DeleteSelectedRows();

gridView1.RefreshData();
}
