Asp.net 如何在 GridView 中隐藏 TemplateField 列

如何在GridView中隐藏TemplateField列？

我try 了以下方法:

<asp:TemplateField ShowHeader="False" Visible='<%# MyBoolProperty %>' >
<ItemTemplate>
    <asp:LinkButton ID="attachmentButton" runat="server" ... />
</ItemTemplate>

但它不起作用，并给出以下错误:

只有具有数据绑定事件的对象才支持数据绑定表达式.

我还试图以编程方式隐藏它，但似乎不可能按名称获取列，因为TemplateField列没有名称.

推荐答案

protected void OnRowCreated(object sender, GridViewRowEventArgs e)
{
         e.Row.Cells[columnIndex].Visible = false;
}

If you don't prefer hard-coded index, the only workaround I can suggest is to provide a HeaderText for the GridViewColumn and then find the column using that HeaderText.

protected void UsersGrid_RowCreated(object sender, GridViewRowEventArgs e)
{
    ((DataControlField)UsersGrid.Columns
            .Cast<DataControlField>()
            .Where(fld => fld.HeaderText == "Email")
            .SingleOrDefault()).Visible = false;
}
