请教一个dataGridView的自定义Column的问题。

[baoma2000]

dataGridView中提供了几个默认的DataGridViewColumn，比如DataGridViewButtonColumn。我想设置另外的DataGridViewColumn的改怎么做。比如calendar,或者我自己的控件。最好有代码，谢谢了！

最通用的方法是重绘，这样想加一般的控件上去都行了。

可以用代码来实现
也可以用编辑模板。
我感觉用代码自己写方便
<Columns>
<asp:BoundField DataField="GRD_ID" HeaderText="序号" InsertVisible="False" ReadOnly="True"
SortExpression="GRD_ID" />
<asp:BoundField DataField="GRD_NAME" HeaderText="年级名" SortExpression="GRD_NAME" />
<asp:TemplateField HeaderText="部名" SortExpression="GRD_DEPID">
<ItemTemplate>
<asp:Label ID="Label1" runat="server" Text='<%# Bind("DEP_NAME") %>' Width="121px"></asp:Label>
</ItemTemplate>
<EditItemTemplate>
<asp:DropDownList ID="DEP_DropDownList" DataSourceID="SqlDataSource1" DataTextField="DEP_NAME" DataValueField="DEP_ID" SelectedValue='<%# Bind("DEP_ID") %>' runat="server"></asp:DropDownList>
</EditItemTemplate>
</asp:TemplateField>
<asp:CommandField ShowDeleteButton="True" ShowEditButton="True" CancelText="取消" DeleteText="删除" EditText="编辑" UpdateText="更新" />
</Columns>
