推荐答案

这里是一个Web服务示例，其中我正在使用PopupControlExtender

Here is a Webservice example where i am using PopupControlExtender

<ajax:PopupControlExtender ID="PopupControlExtender1" runat="server"

               PopupControlID="Panel1"

               TargetControlID="Image1"

               DynamicContextKey='<%# Eval("ProgrammeID") %>'

               DynamicControlID="Panel1"

               DynamicServiceMethod="GetDynamicContent" Position="Bottom">
            </ajax:PopupControlExtender>

<script runat="server">
 [System.Web.Services.WebMethod(), System.Web.Script.Services.ScriptMethodAttribute()]
  
    public static string GetDynamicContent(string contextKey)
    {
 
        string constr = "Data Source=SAYAN-PC;Initial Catalog=nayuma;Trusted_connection=false;Integrated Security=false;User Id=sa;Password=lock;";
        string query = "SELECT Context FROM ProgrammeSchedule WHERE ProgrammeID = " + contextKey;

        System.Data.SqlClient.SqlDataAdapter da = new System.Data.SqlClient.SqlDataAdapter(query, constr);
        System.Data.DataTable table = new System.Data.DataTable();

        da.Fill(table);

        StringBuilder b = new StringBuilder();

        b.Append("<table style="background-color:#f3f3f3; border: #2A2A2A 3px solid; ");<br mode="hold" />        b.Append("width:280px; font-size:10pt; font-family:Verdana;" cellspacing="0" cellpadding="3">");

        b.Append("<tr><td colspan="3" style="background-color:#2A2A2A; color:white;">");
        b.Append("Context"); b.Append("</td></tr>");
        b.Append("<tr><td style="width:80px;">Details</td>");


        b.Append("<tr>");
        b.Append("<td>" + table.Rows[0]["Context"].ToString() + "</td>");

        b.Append("</tr>");

        b.Append("</tr></table>");

        return b.ToString();
    }
</script>
