ASP.NET BoundColumn ToolTip

Question

有没有办法将工具提示添加到BoundColumn？这是我的代码......

    <asp:BoundColumn DataField="PersonName" SortExpression="PersonName" HeaderText="Name">
        <HeaderStyle HorizontalAlign="Center" Width="10%" VerticalAlign="Top"></HeaderStyle>
        <ItemStyle HorizontalAlign="Center" VerticalAlign="Top"></ItemStyle>
    </asp:BoundColumn>

之前我正在使用tablecell并决定切换到绑定列，这样做我意识到工具提示不是boundcolumn的属性，我需要工具提示。

所以它实际上是一个DataGrid控件，你想在header-cell上有一个工具提示。您可以使用ItemDataBound：

Protected Sub SortableDataGrid_ItemDataBound(sender As Object, e As DataGridItemEventArgs) Handles Grid0.RowDataBound
    Select Case e.Item.ItemType
        Case ListItemType.Header
            'presuming it's the first column:
            e.Item.Cells(0).ToolTip = "Your tooltip for this header cell"
    End Select
End Sub

如果它是GridView，则代码类似：

Protected Sub SortableGridView_RowDataBound(sender As Object, e As GridViewRowEventArgs) Handles Grid0.RowDataBound
    Select Case e.Row.RowType
        Case DataControlRowType.Header
            'presuming it's the first column:
            e.Row.Cells(0).ToolTip = "Your tooltip for this header cell"
    End Select
End Sub
