如何访问vb.net按钮点击事件对模式弹出按钮点击事件？在设计部分

Question

我的源代码是：

 
<asp:Panel ID="Panel1" runat="server" Style="display: none" CssClass="modalPopup"> 
      <asp:Panel ID="Panel3" runat="server" Style="cursor: move;background-color:#DDDDDD;border:solid 1px Gray;color:Black"> 
       <div> 
        <p>Would you like to book the seat?</p> 
       </div> 
      </asp:Panel> 
       <div> 
        <p style="text-align: center;"> 
         <asp:Button ID="OkButton" runat="server" Text="OK" OnClick="OkButton_Click" />      
         <asp:Button ID="CancelButton" runat="server" Text="Cancel" /> 
        </p> 
       </div>     
     </asp:Panel> 

我要访问OkButton_Click在vb.net 的代码如下：

 
Protected Sub OkButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles OkButton.Click 
     Dim con As OleDbConnection = New OleDbConnection("Provider=Microsoft.Jet.Oledb.4.0 ;data source=" & Server.MapPath(".\App_Data\IFFI.mdb") & ";") 
     Dim Cmd As OleDbCommand 
     Dim Qry As String 
     con.Open() 
     Qry = "update seat_layout set lock_status=1,booked_status=1 where theatre_id='" + ddl_theatre.SelectedValue.ToString() + "' and seat_id='" + Session("seat_id").ToString() + "'" 
     Dim img As Button 
     img.BackColor = Drawing.Color.Purple 
     img.Enabled = False 
     Cmd = New OleDbCommand(Qry, con) 
     Cmd.ExecuteNonQuery() 
     con.Close() 
    End Sub 

确定按钮单击未访问点击事件。请帮助

尝试更改为“公共”而不是“保护”的子。 （我很抱歉，如果这个问题太旧了，我现在不能回答）。
