在C#中的中继器控件中的应用条件 [英] Applying condition in Repeater Control in C#

问题描述

我想在转发器控制中应用条件.

如果数据库表中的字段为null或为空，则不得显示与其关联的标签.

已经尝试过:

I want to apply condition in repeater control.

If the field in database table in null or empty, the label associated with it must not be displayed.

Have tried with this:

<asp:Label ID="Label1" runat="server" Font-Size="X-Large" ForeColor="DeepSkyBlue"

                   Style="position: static" Text="Search Results" visible="<%# CanIDisplayBeds(DataBinder.Eval(Container.DataItem,"Beds")) %>" ></asp:Label>

其中后面的代码具有以下功能:

where code behind has following function:

protected bool CanIDisplayBeds(Object retBeds)
    {
        return (retBeds != "");
    }

收到错误消息:服务器标签格式不正确."

请帮忙.

我不知道该怎么办.

现在我找到了解决方法.
如下...

Getting error: "Server tag not well formed."

Now I have found out the solution.
It is as below...
