Question

我在ASP.NET中创建了一个表单。代码如下所示

    <asp:Literal ID="ErrorMessage" runat="server" ></asp:Literal>
</span>

<asp:Label ID="SchoolNameLabel" runat="server" Text="School Name " AssociatedControlID="SchoolName"></asp:Label>
<asp:TextBox ID="SchoolName" runat="server" Height="16px" Width="337px" CssClass="textEntry"></asp:TextBox>
<asp:Label ID="Label15" runat="server" Font-Size="Larger" ForeColor="Red" Text="*"></asp:Label>

     ErrorMessage="City is Required" ToolTip="City is Required" ValidationGroup="AddSchoolValidationGroup"></asp:RequiredFieldValidator>

     ErrorMessage="Zip Code is Required" ToolTip="Zip Code is Required" ValidationGroup="AddSchoolValidationGroup"></asp:RequiredFieldValidator>

<asp:Label ID="EmailLabel" runat="server" Text="Email Address" AssociatedControlID="Email"></asp:Label>:

     ValidationGroup="AddschoolValidationGroup">*</asp:RequiredFieldValidator>

       ValidationGroup="AddSchoolValidationGroup">*</asp:CompareValidator>
<asp:Label ID="Label14" runat="server" ForeColor="Red" Text="* = Required"></asp:Label>

<asp:ImageButton ID="Cancel" runat="server" OnClick="cancelClick" ImageUrl="~/Styles/images/cancel-btn.png" />
<asp:ImageButton ID="Submit" runat="server" OnClick="submitClick" ImageUrl="~/Styles/images/submit-btn.png" />
</form>

此表单包含一些字段，如学校名称，街道地址，城市，电子邮件，符合电子邮件等。随着Asp.net验证控件和两个图像按钮，一个被命名为取消，另一个被命名为提交。当我点击提交我希望使用该验证控件验证表单并引发一个事件“submitclick”。当我点击取消时我想提出一个事件cancelclick.Can任何人解释如何在我点击提交'图像按钮时验证表单”。

Answer 1

在ValidationGroup上添加ImageButton ID="Submit"：

<asp:ImageButton
       ID="Submit"
       runat="server"
       OnClick="submitClick"
       ImageUrl="~/Styles/images/submit-btn.png"
       ValidationGroup="AddSchoolValidationGroup" CausesValidation="true"

/>

Answer 2

在按钮中设置CausesValidation =“True”会让你到达那里。

带有提交和取消按钮的ASP.NET表单
