changepassword控件的问题 [英] problem with changepassword control

问题描述

在我的网络表单中使用带有6个标签的ajaxtabcontrol，在一个标签中我已经放置了changepassword控件。

，当我获得值时，代码落后对于confirmnewpassword，它给出的错误为：changepassword1在当前上下文中不存在。



这里是设计代码

in my web form am using ajaxtabcontrol having 6 tabs, in one tab i have placed changepassword control.
with in code behind when i get the value of confirmnewpassword , it's giving error as: changepassword1 doesnot exist in the current context.

here is the code for design

<ajax:TabPanel ID="tbpnlsetting" runat="server" >&lt;HeaderTemplate>

 Settings

    &lt;/HeaderTemplate>

    <ContentTemplate>



    <asp:Panel ID="settings" runat="server" Width="671px" Height="214px">

        <asp:ChangePassword ID="ChangePassword1" runat="server"

            onchangedpassword="ChangePassword1_ChangedPassword" PasswordLabelText="Current Password"">
        </asp:ChangePassword>

 </asp:Panel>


    </ContentTemplate>


</ajax:TabPanel>
</ajax:TabContainer></pre></pre>

和代码背后是

and code behind is

protected void ChangePassword1_ChangedPassword(object sender, EventArgs e)
       {
           using (MySqlConnection con = new MySqlConnection(ConnectionString))
           {
               String query = "update  admin set Password ='" + ChangePassword1.ConfirmNewPassword + "' where  Password ='" + ChangePassword1.CurrentPassword + "'";
               MySqlCommand command = new MySqlCommand(query,con);
               con.Open();
               command.ExecuteNonQuery();
           }
       }

推荐答案

如果控件名称不可用或重复，则会出现此错误



步骤1：

转到Designer视图，在那里看到表单和控件，单击Changepassword1control并查看属性它（可按F4），如果名称正确



转到aspx.cs



按CTRL + F = Changepassword1搜索整个页面的重复项，如果找到则删除重复项。



建议：请遵循正确的命名约定，以便这些错误可以是最小化。



最好的:)如果你需要更多的帮助，请回信

This Error Occurs if the control name is not available or duplicated

Step1:
Go to the Designer view, where you see the form and controls , click on the Changepassword1control and look at the properties of it (can press F4),if the name is correct

Go to aspx.cs

press CTRL+F =Changepassword1 search the entire page for duplicates, if found remove the duplicates.
