我怎样才能把我的箭头方向箭头在asp.net颜色coolgrid基于从数据库中的信息？

问题描述

箭头颜色在数据库字段中给出 - OverallStatusCd和箭头背景色在数据库现场OverallTrendCd给出。
CSS是箭头和研究背景颜色写的。
我们可以通过改变'了使用下面的code访问这些东西，下，右，左和颜色是通过改变改变了绿色，红色

Arrow colour is given in the database field - "OverallStatusCd" and arrow background colour is given in database field- "OverallTrendCd".Css is written for arrows and backgroud colour.We can access these things using the code below by changing 'up','down', 'right','left' and colour is changed by changing 'green', 'red'

跨度ID =sptrend=服务器级=箭头向上箭头图标arrowgreen> / SPAN

span id="sptrend" runat="server" class="arrow arrow-up-icon arrowgreen">/span

我如何使用这个动态的基础上，从数据库中的信息？
OverallTrendCd所赐R代表红色，'Y'黄色
OverallStatusCd能值上，下，等等...

How can I use this dynamically based on the information from database?"OverallTrendCd" is giving 'R' for RED, 'Y' for YELLOW"OverallStatusCd" is giving values 'Up','Down', etc...

请你帮我＃

推荐答案

尝试：

<span id="sptrend" runat="server" class='<%# String.Format(("{0}{1}"), Eval("OverallStatusCdClass"), Eval("OverallTrendCdClass "))%>'></span>

如果你必须inclue箭头或比，是很难codeD，然后你可以改变字符串数据库以外的任何其他字符串.Format（（{0} {1}）是的String.Format（（箭头{0} {1}）

if you must inclue 'arrow' or any other string other than in the DB that is hard coded then you can alter String.Format(("{0}{1}"), to be String.Format(("arrow {0}{1}")

注：我假设你的跨度在数据绑定控件。

Note: I assume that your span is in a databound control..

SELECT OverallStatusCd, OverallTrendCd, 
CASE WHEN OverallStatusCd = 'Up'  THEN 'up'
     WHEN OverallStatusCd = '.Down' THEN 'down'
END AS OverallStatusCdClass ,
CASE WHEN OverallTrendCd = 'R'  THEN 'red'
     WHEN OverallTrendCd = 'Y' THEN 'yellow'
END AS OverallTrendCdClass 
FROM    YourTable

有关的SqlDataSource它会像在aspx页面（帮您联系延长我的答案在你心中的东西）：

For SqlDataSource it will be something like in an aspx page (to help you relate things in your mind extending my answer) :

<asp:Repeater ID="Repeater1" runat="server" DataSourceID="SqlDataSource1">
   <ItemTemplate>
        <span id="sptrend" runat="server" class='<%# String.Format(("{0}{1}"), Eval("OverallStatusCdClass"), Eval("OverallTrendCdClass "))%>'></span>
   </ItemTemplate>
</asp:Repeater>

<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:DefaultConnection %>" SelectCommand="SELECT OverallStatusCd, OverallTrendCd, 
                CASE WHEN OverallStatusCd = 'Up'  THEN 'up'
                     WHEN OverallStatusCd = '.Down' THEN 'down'
                END AS OverallStatusCdClass ,
                CASE WHEN OverallTrendCd = 'R'  THEN 'red'
                     WHEN OverallTrendCd = 'Y' THEN 'yellow'
                END AS OverallTrendCdClass 
                FROM YourTable">
</asp:SqlDataSource>
