c# - 仅在 Gridview 的最后一行显示复选框？

Question

是否可以有一个仅在编辑 GridView 的最后一行时显示的复选框？

我在 EditItemTemplate 中尝试过这样的事情:

<asp:CheckBox ID="chkNextDay" runat="server" 
              ToolTip="Is it a next-day departure?"
              Enabled="true" 
              Checked='<%# DateTime.Parse(Eval("OutHour","{0:d}")).Date >
                           DateTime.Parse(Eval("InHour","{0:d}")).Date  %>'/>

然后在代码隐藏中，我尝试像这样隐藏最后一行以外的行:

protected void grvOutHour_RowEditing(object sender, GridViewEditEventArgs e)
        {
            GridView grvOutHour = (GridView)this.grvReport.Rows[grvReport.EditIndex].FindControl("grvOutHour");
            TextBox txtBox = (TextBox)grvOutHour.Rows[e.NewEditIndex].FindControl("txtEditOutHour");
            CheckBox nextDay = (CheckBox)grvOutHour.Rows[e.NewEditIndex].FindControl("chkNextDay");
            if (grvOutHour.Rows.Count-1 != e.NewEditIndex)
                nextDay.Visible = false;
        }

这几乎有效，但复选框一直显示所有字段，我认为是因为 RowDataBound 在 RowEditing 之后再次被调用，所以它再次呈现整个事物:(

有什么建议吗？

改用 RowDataBound...

protected void grvOutHour_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowState == DataControlRowState.Edit)
    {
        GridView grid = (GridView)sender;
        CheckBox nextDay = (CheckBox)e.Row.FindControl("chkNextDay");
        nextDay.Visible = (e.Row.RowIndex == (grid.Rows.Count - 1));
    }
}
