c# - 编辑 ASP.NET 控件的内容

Question

下面是我的Default.aspx的内容

<asp:Content ID="BodyContent" runat="server" ContentPlaceHolderID="MainContent">
    <h2>
        WELCOME     
    </h2>
    <p id="exampleId">
        I want to edit here
    </p>

</asp:Content>

我希望能够找到 ID 为“exampleID”的控件，并使用 C# 向其中写入一些内容。

Answer 1

runat = "server" was missing in the tag to access it from code behind.

HTML

<asp:Content ID="BodyContent" runat="server" ContentPlaceHolderID="MainContent">
    <h2>
        WELCOME     
    </h2>
    <p id="exampleId" runat = "server">
        I want to edit here
    </p>

</asp:Content>

C#代码

exampleId.InnerText = "Your text";
