當我在單擊出現的問題，我tryied把OnClick事件，但仍然發生了錯誤。
<asp:Button id="btnSelecionarData" runat="server" Text="Buscar" />
錯誤
Failed to load viewstate. The control tree into which viewstate is being loaded must match the control tree that was used to save viewstate during the previous request. For example, when adding controls dynamically, the controls added during a post-back must match the type and position of the controls added during the initial request.

有人能幫助我嗎？
請出示'btnSelecionarData'按鈕的處理程序 – opewix
當我嘗試把一個'OnClick'的錯誤仍然發生 –
