与验证有关 [英] related to validation

问题描述

首先我描述一下情况：



从网页上如果我成功插入记录然后没有问题，但如果发生了一些错误，如电子邮件ID已经存在，那么它将重点关注电子邮件ID文本框而不是其他。



在.aspx

firstly I describe situation:

From web page if i insert record successfully then no problem but if some error occur like email id already exist then it focus to the email id text box rather then other.

In .aspx

<asp:TextBox ID="txtEmailId" runat="server" Width="30 %"  />
                            <asp:RequiredFieldValidator ID="RequiredFieldValidator7" Display="Dynamic" ValidationGroup="addClient"

                                runat="server" ErrorMessage="Please enter Email Id" ControlToValidate="txtEmailId"

                                Width="30 %" SetFocusOnError="true"></asp:RequiredFieldValidator>

在.aspx.cs

In .aspx.cs

catch (SqlException sql)
           {
               //ScriptManager.RegisterStartupScript(this, this.GetType(), "alert", "alert('Email ID already exist !!!');window.location.href='ClientRegistraion.aspx';", true);
               Response.Write("<script language=javascript>alert('Email ID already exist !!!')</script>");
               txtEmailId.Focus();
               RequiredFieldValidator7.Enabled = true;

           }

谢谢提前。

thanks in advance.

推荐答案

我看到你有 SetFocusOnError =true为 RequiredFieldValidator 。

因为它在验证失败时设置，焦点将设置为验证失败的控件。设置 SetFocusOnError =false，如果你想改变那种行为。

I see that you have SetFocusOnError="true" propery set for RequiredFieldValidator.
since it is set when there is validation failure, focus will be set to the control which failed in validation. Set SetFocusOnError="false", if you wish to change that behaviour.
