    <Fields>
        <asp:BoundField DataField="ProgramName" HeaderText="Program:" />
        <asp:BoundField DataField="StudyYearName" HeaderText="Study Year:" />
        <asp:HyperLinkField DataTextField="OrganisationName" HeaderText="Apprenticeship:&nbsp;" NavigateUrl="Apprenticeships.aspx" />

                <asp:Label ID="labEndDate" runat="server" Text='<%# Eval("FinishDate","{0:d/MM/yyyy}") %>'></asp:Label>
            </ItemTemplate>

    <FooterTemplate>
        <asp:LinkButton ID="lbAddProgramUnits" runat="server" OnClick="AddProgramUnits_Click" ForeColor="White" Font-Bold="true"
            OnClientClick="return confirm('Import the Program Units listed - this may overwrite unit dates. Are you sure?');">Import from Program</asp:LinkButton>&nbsp;&nbsp;
        <a href="#" onclick="showhelp('progimphelp');" style="color:White;font-weight:bold;">Help</a>
    </FooterTemplate>
    <FooterStyle HorizontalAlign="Center" BackColor="LightSlateGray" />
</asp:DetailsView>

我希望能够展现每当上述绑定列已更改颜色的提示。

I want to be able to show a tooltip whenever one of the above Boundfields has changed color.

在我的C＃codebehind，我有code，改变依赖于数据的某些情况下，这些绑定列的颜色。这是工作的罚款。

In my C# codebehind, I have code that changes the color of these boundfields depending on certain conditions of the data. This is working fine.

但我想要的是能够给用户一个提示当过他们将其鼠标在这些绑定列且仅当此字段是不同的色彩，在我的情况

But what I want is to be able to give the users a tooltip when ever they hover their mouse over these Boundfields and ONLY if that field is coloured differently, in my case

color.Yellow

color.Yellow

推荐答案

如果您在颜色设置为黄色在DetailsView根据某些条件，您可以数据绑定事件设置提示在同一区块：

If you are setting the color to yellow in the DetailsView DataBound event based on some criteria, you can set the tooltip in that same block:

DetailsViewRow.Cells[indexofyellowfield].ToolTip = "some help from code-behind";
