  • DevExpress GridControl使用教程:之 添加 checkbox 复选框

    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 :

     注意:Tag 显示在下图
