按鈕拒絕工作

Question

我有一個標準的按鈕應該調用一個方法，但它只是拒絕工作，我不明白爲什麼。

ASP代碼：

<asp:FileUpload ID="FileUpload1" runat="server" /> 
     <asp:Button 
      ID="UploadButton" runat="server" onclick="UploadButton_Click" Text="Change Logo" /> 

後面的代碼：

protected void UploadButton_Click(object sender, EventArgs e) 
     { 
      PasswordLabel.Visible = true; 
      PasswordLabel.Text = "TEST Before"; 
      Image_Inserting(this); 
      PasswordLabel.Text = "TEST After"; 

     } 

我剛添加的文本框方法來測試它，但它似乎並沒有被回發（甚至當我刪除I​​mage_Inserting通話）。所有其他按鈕都可以正常工作，所以我不知道爲什麼這個按鈕不起作用。

Answer 1

我的猜測是，它是造成其他（可能是隱藏的）驗證運行。請務必設置原因驗證至虛假。

Answer 2

報價整體PAGE-按鈕代碼： *我剛添加的文本框方法*

我想我們試圖更新密碼的textBox你不能。

只有：

PasswordLabel .Attributes["value"] = "aaa";
