我可以更改 BoundField 列的 HeaderText 的列跨度吗

发布于 2024-12-09 13:20:35 字数 887 浏览 0 评论 0原文

我有一个由三列组成的“状态”簇。我想让标题行跨越所有三个。我知道我可以在 HTML 中使用 colspan="3" 参数和 th 标签。如何使用 BoundField 实现此目的？

现在存在的示例代码片段

<asp:BoundField DataField="Priority" HeaderText="Priority" />
<asp:TemplateField ItemStyle-Width="50">
  <ItemTemplate>
    <asp:ImageButton ID="btnMinus" CommandName="minus" runat="server" ImageUrl="~/Images/arrowUp_ico.gif" BorderWidth="1" BorderStyle="Ridge" />
    <asp:ImageButton ID="btnPlus" CommandName="plus" runat="server" ImageUrl="~/Images/arrowDown_ico.gif" BorderWidth="1" BorderStyle="Ridge" />
  </ItemTemplate>
</asp:TemplateField>
<asp:BoundField DataField="ProjectName" HeaderText="Project" />
<asp:BoundField DataField="Group" HeaderText="Group" />
<asp:BoundField DataField="Assigned" HeaderText="Assigned" />

......等等。

我需要标题文本“优先级”来跨越其本身和接下来的两列。

I have a 'status' cluster of three columns. I want to have the header row span all three. I know I can use the colspan="3" parameter with the th tag in HTML. How do I accomplish this with BoundField?

Sample code snippet as it exists now...

<asp:BoundField DataField="Priority" HeaderText="Priority" />
<asp:TemplateField ItemStyle-Width="50">
  <ItemTemplate>
    <asp:ImageButton ID="btnMinus" CommandName="minus" runat="server" ImageUrl="~/Images/arrowUp_ico.gif" BorderWidth="1" BorderStyle="Ridge" />
    <asp:ImageButton ID="btnPlus" CommandName="plus" runat="server" ImageUrl="~/Images/arrowDown_ico.gif" BorderWidth="1" BorderStyle="Ridge" />
  </ItemTemplate>
</asp:TemplateField>
<asp:BoundField DataField="ProjectName" HeaderText="Project" />
<asp:BoundField DataField="Group" HeaderText="Group" />
<asp:BoundField DataField="Assigned" HeaderText="Assigned" />

...etc.

I need the header text 'Priority' to span the itself and the next two columns.

像往常一样，当需要很长时间才能得到答案时，我会自己找出答案。解决方案是转到 init 部分（或等效的代码，具体取决于您的项目）后面的代码并添加两行...

myDataGrid.HeaderRow.Cells[n].ColumnSpan = 2;
MyDataGrid.HeaderRow.Cells[n+1].Visible = false;

这会将第一个标题单元格 (n) 扩展到两列宽并删除相邻的单元格。如果省略第二行，该列的标题就会被推到右侧。

As is usual for me, when it takes a long time to get an answer I figure it out myself. The solution is to go to the code behind in the init section (or equivalent, depending on your project) and add two lines...

myDataGrid.HeaderRow.Cells[n].ColumnSpan = 2;
MyDataGrid.HeaderRow.Cells[n+1].Visible = false;

This extends the first header cell (n) out to be two columns wide and removes the adjacent one. If you leave out the second line the header for that column just gets pushed to the right.
