获得Ajax控件的价值 [英] get value for ajax control

问题描述

我有一个列表视图，并且列表视图包含Gravatar(ajax控件)

我试过了:

i have a listview and listview contains a Gravatar(ajax control)

i tried:

<asp:ListView ID="ListView1" runat="server" DataSourceID="SqlDataSource1">
 <ItemTemplate>

  <asp:HiddenField ID="HiddenField1" runat="server" Value='<%# Eval("email") %>' />
  
  <ajaxToolkit:Gravatar ID="Gravatar1" runat="server" Email="<%= HiddenField1.Value %>" Size="70" Rating="R" DefaultImageBehavior="MonsterId" />


 </ItemTemplate>
</asp:ListView>
-----

<asp:SqlDataSource ID="SqlDataSource1" runat="server" 

           ConnectionString="<%$ ConnectionStrings:TestConnectionString1 %>" 

           SelectCommand="SELECT [email] FROM [TblComments]"></asp:SqlDataSource>

但这没有帮助.

ConnectionStrings:TestConnectionString1 %>" SelectCommand="SELECT [email] FROM [TblComments]"></asp:SqlDataSource>

您以与HiddenField DataBinding
相同的方式获取电子邮件

You get it the same way your do for the HiddenField, DataBinding

<ajaxToolkit:Gravatar ID="Gravatar1" runat="server" Email="<%Eval("email")%>" Size="70" Rating="R" DefaultImageBehavior="MonsterId" />

您甚至不需要HiddenField.除非您将其用于其他用途

You don''t even need the HiddenField. Unless you are using it for something else
