Asp.net DevExpress GridView中的CheckComboBoxColumn

我想得到CheckedList下拉控件，它是一个基本的下拉列表，每个列表项前面都有复选框

我在他们的官方网站上找到了，但我希望在ASPxGridView专栏中也能看到同样的效果。

我不太明白你的问题。是否要在

ASPxGridview

列中使用

CheckComboBoxColumn

？如果是这样，你可以这样使用它

    <dx:ASPxGridView ID="grid" ClientInstanceName="grid" runat="server"
.........................
<Columns>
.........................
<EditItemTemplate> // If your Gridview has Edit Property. 
.........................
<dx:ASPxListBox ...

    {
        ASPxDropDownEdit dropdownedit = sender as ASPxDropDownEdit;
        ASPxGridView grid = dropdownedit.NamingContainer.NamingContainer as ASPxGridView;

        string key = grid.UniqueID;
        string visibleIndex = (dropdownedit.NamingContainer as GridViewDataItemTemplateContainer).VisibleIndex +
key;
        dropdownedit.ClientInstanceName = "dde" + visibleIndex;

        dropdownedit.ClientSideEvents.DropDown =
            String.Format("function(s,e) {{ SynchronizeGridValues(s, e, grid{0});}}", visibleIndex);

        dropdownedit.ClientSideEvents.TextChanged =
            String.Format("function(s,e) {{SynchronizeGridValues(s, e, grid{0});}}", visibleIndex);

        string key = grid.UniqueID;
        string visibleIndex = (button.NamingContainer.NamingContainer.NamingContainer.NamingContainer as

        button.ClientSideEvents.Click = String.Format("function(s, e){{dde{0}.HideDropDown();}}", visibleIndex);

        curGrid.ClientInstanceName = "grid" + visibleIndex;

        curGrid.ClientSideEvents.SelectionChanged =
            String.Format("function(s,e) {{ OnGridSelectionChanged(s, e, dde{0});}}", visibleIndex);

是的，我想在ASPxGridView列中有一个CheckComboBoxColumn，我在添加我发布链接的演示中的标记代码时有些困惑，请您指导我如何将该代码与GridView标记代码合并并发布合并结果？谢谢。我更新了我的答案。如果这不是你想要的，请告诉我。好的，我会检查一下，看看，但真的吗？3嵌套网格视图？
