添加一列，FieldName为"FLAG"，将ColumnEdit设置为复选框样式。

gridview1   =》optionsbehavior =》  editable设置为true   （如果自己定义全选，取消全选此处可以设置false）

将要绑定的DataTable添加列"FLAG",Type为bool。

gridview1   =》columnEdit => new =》checkEdit 

此时就会出现复选框 但是 复选框 无法选择 需要继续 给 gridView 添加

点击事件  RowCellClick

private void gv_RowCellClick(object sender, DevExpress.XtraGrid.Views.Grid.RowCellClickEventArgs e)
{
int index = this.gv.FocusedRowHandle;
selStudent = gv.GetRow(index) as StudentDTO;
if (selStudent == null)
{
FrmAlert.ShowMessageBoxErrorDialog(this, "请选中一行！");
return;
}
if (e.Column.Tag.ToSafeString() == "checkbox")
{
int selectIndex = this.gv.FocusedRowHandle;
StudentDTO row = this.gv.GetRow(selectIndex) as StudentDTO;
if (row != null)
{
DevExpress.Data.CustomSummaryEventArgs e1 = new DevExpress.Data.CustomSummaryEventArgs();
row.Flag = !row.Flag;
}
this.gv.RefreshData();
}
}

获取：

string value = gridview.GetDataRow(i)["FLAG"].toString();

value == "true" ||  "" ("false")

设置为多选

gridView1 .OptionsSelection.MultiSelect = true;

gridView1 .OptionsSelection.MultiSelectMode = DevExpress.XtraGrid.Views.Grid.GridMultiSelectMode.RowSelect;

代码如下 ：
