使用过程/数据集绑定数据列表

运行时错误-超过最大存储过程，函数，触发器或视图嵌套级别

html:
在DataList中:-

error on runtime-Maximum stored procedure, function, trigger, or view nesting level exceeded

html:
In DataList:-

<itemtemplate>
                    <tr>
                        <td>
                            <%#Eval("e_id") %>
                        </td>
                        <td>
                            <%#Eval("e_name") %>
                        </td>
                        <td>
                            <%#Eval("e_sal") %>
                        </td>
                    </tr>
                
</itemtemplate>

代码(.cs):

code(.cs):

protected void Page_Load(object sender, EventArgs e)
        {
SqlConnection con = new SqlConnection(str_con);
            con.Open();
            SqlCommand cmd = new SqlCommand("getdata", con);
            cmd.CommandType = CommandType.StoredProcedure;
SqlDataAdapter da = new SqlDataAdapter(cmd);
            DataSet ds = new DataSet();
            da.Fill(ds);<<------------error
DataList1.DataSource = ds;
            DataList1.DataBind();
            con.Close();

它工作正常，但现在相同的代码给出了错误！ :(

It was working fine but now same code is giving error!! :(
