“ASP.default_aspx”并不包含“SqlDataSource1_Selecting”的定义

错在那里应该怎么写？

解决方案 »

  1.   

    Default.aspx.cs 文件里
        protected void SqlDataSource1_Selecting(object sender, SqlDataSourceSelectingEventArgs e)
        {
           
        }或者删除OnSelecting="SqlDataSource1_Selecting"
      

  2.   

    <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString=" <ConnectionStrings:lbs_TestConnectionString />"
                SelectCommand="SELECT * FROM [data]" OnSelecting="SqlDataSource1_Selecting"> </asp:SqlDataSource> 
    在cs文件中没有相对应的事件
      

  3.   

    删除
    protected void SqlDataSource1_Selecting(object sender, SqlDataSourceSelectingEventArgs e) 
        { 
          
        } 
      

  4.   

    一般这种情况都是你在cs源码里删除了
    protected void SqlDataSource1_Selecting(object sender, SqlDataSourceSelectingEventArgs e) 
        { 
          
        } 
    而aspx文件里的OnSelecting="SqlDataSource1_Selecting却没删除导致！
