如何在GridView中隐藏TemplateField列？
我试过以下：
<asp:TemplateField ShowHeader="False" Visible='<%# MyBoolProperty %>' >
<ItemTemplate>
<asp:LinkButton ID="attachmentButton" runat="server" ... />
</ItemTemplate>
但它没有工作，并给出以下错误：
Databinding expressions are only supported on objects that have a DataBinding event.
System.Web.UI.WebControls.TemplateField does not have a DataBinding event.
解决方法
protected void OnRowCreated(object sender,GridViewRowEventArgs e)
{
e.Row.Cells[columnIndex].Visible = false;
}
如果你不喜欢硬编码的索引，唯一的解决方法，我可以建议是为GridViewColumn提供一个HeaderText，然后找到使用该HeaderText的列。
protected void UsersGrid_RowCreated(object sender,GridViewRowEventArgs e)
{
((DataControlField)UsersGrid.Columns
.Cast<DataControlField>()
.Where(fld => fld.HeaderText == "Email")
.SingleOrDefault()).Visible = false;
}
