如何根据数据源条件更改中继器控件的可见性？ [英] How Do I Change Visibility Of A Repeater Control, Based On Datasource Condition?

问题描述

我想设置ASP的可见性：LINKBUTTON基于Repeater DataSource属性的条件TYPE



如果DataItem.Type属性==实际将可见性设置为true，否则为false;



显然数据源中的某些行将为true，有些行将为false，我只想隐藏当前行所有按钮。



我尝试过以下代码：

I am wanting to set the visibility of a ASP:LINKBUTTON based on the condition of the Repeaters DataSource property TYPE

if the DataItem.Type property == "practical" set visibility to true otherwise false;

Obviously some rows in the datasource will be true and some will be false, i only want to to hide the current row not all buttons.

I have tried the below code:

Visible="<%# DataBinder.Eval(Container,"DataItem.Type").ToString().ToLower() == "practical" ? true : false %>"

i还在语音标记中尝试了值true和false，但没有优势：



错误我收到的是：

i have also tried the values true and false in speech marks but to no prevail:

error i recieve is:

Parser Error Message: The server tag is not well formed.

Source Error: 


Line 84:                                     </td>
Line 85:                                     <td width="17%">
Line 86: <asp:LinkButton runat="server" ID="lbAddDates" Visible="<%# DataBinder.Eval(Container,"DataItem.Type").ToString().ToLower() == "practical" ? "true" : "false" %>" CommandName="AddDates" OnCommand="lbCourseActionItems_Click" CommandArgument='<%# DataBinder.Eval(Container, "DataItem.Id").ToString() + "," + DataBinder.Eval(Container, "DataItem.IsActive").ToString() + "," + DataBinder.Eval(Container, "DataItem.Title").ToString()  %>' class="button">
</asp:LinkButton>

任何有关此问题的帮助将不胜感激。

Any help on this would be greatly appreciated.

推荐答案

您的服务器标签包含引号。使用单引号作为外部引号以获得格式良好的标记。

Your server tag includes quotes. Use single quotes as outer quotes to get a wellformed tag.

Visible='<%# DataBinder.Eval(Container,"DataItem.Type").ToString().ToLower() == "practical" ? true : false %>'
