asp.net - 在 ASP.Net 标记中显示字符串变量的值

Question

是否可以从代码隐藏文件中的字符串变量中获取值并将其显示在此标记中？

<h1>People Authorized to Release Children for <TheVariableGoesHere>  </h1>

我们想要包含的变量名为 strForename。

Protected Sub GridViewParentsSummary_SelectedIndexChanged(sender As Object, e As EventArgs) Handles GridViewParentsSummary.SelectedIndexChanged

    IntParentsID = GridViewParentsSummary.DataKeys(GridViewParentsSummary.SelectedIndex).Value
    strForename = GridViewParentsSummary.DataKeys(GridViewParentsSummary.SelectedIndex).Values("Forename")

    blnAddModeIsSelected = False

    Response.Redirect("AuthorizationForChildReleaseDetails.aspx")

End Sub

Answer 1

实现这一点的方法是通过调用隐藏方法的代码。

对于 C# 来说是这样的

<h1>People Authorized to Release Children for <% =this.GetForename() %> </h1>

或者 VB.NET 的这个

<h1>People Authorized to Release Children for <% =Me.GetForename() %> </h1>

以及 C# 背后的代码

protected string GetForename() 
{
    return GridViewParentsSummary.DataKeys(GridViewParentsSummary.SelectedIndex).Values("Forename");
}

或在 VB.NET 中

Protected Function GetForename() As String
    Return GridViewParentsSummary.DataKeys(GridViewParentsSummary.SelectedIndex).Values("Forename")
End Function
