带有提交和取消按钮的ASP.NET表单

我在ASP.NET中创建了一个表单。代码如下所示

<form id="AddSchool" method="post" runat="server">
<span class="failureNotification">
    <asp:Literal ID="ErrorMessage" runat="server" ></asp:Literal>
</span>
<asp:ValidationSummary ID="AddSchoolValidationSummary" runat="server" CssClass="failureNotification" ValidationGroup="AddSchoolValidationGroup"/>
<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>

<asp:RequiredFieldValidator ID="CityRequired"  runat="server" ControlToValidate="City" CssClass="failureNotification"
     ErrorMessage="City is Required" ToolTip="City is Required" ValidationGroup="AddSchoolValidationGroup"></asp:RequiredFieldValidator>

<asp:Label ID="StateLabel" runat="server" Text="State " AssociatedControlID="StateList"></asp:Label>
<asp:DropDownList ID="StateList" runat="server" Height="25px" Width="119px" DataSourceID="SqlDataSource1" DataTextField="StateName" DataValueField="StateName" CssClass="textEntry">
 <asp:ListItem>Select A State</asp:ListItem>
</asp:DropDownList>

<asp:RequiredFieldValidator ID="ZipCodeRequired" runat="server" ControlToValidate="ZipCode" CssClass="failureNotification"
     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>:
<asp:TextBox ID="Email" runat="server" Width="304px" Height="16px" CssClass="textEntry"></asp:TextBox>

    ErrorMessage="E-mail is required." ToolTip="E-mail is required."  ValidationGroup="AddSchoolValidationGroup">*</asp:RequiredFieldValidator>
<asp:RegularExpressionValidator ID="EmailFormat" runat="server"  ControlToValidate="Email" CssClass="failureNotification" 
    ErrorMessage="The email address entered does not appear to be valid." ValidationGroup="AddSchoolValidationGroup" 
     ValidationExpression="([A-Z]|[a-z]|[0-9])+[@]([A-Z]|[a-z]|[0-9])+\.([A-Z]|[a-z]){2,6}" Display="Dynamic">*</asp:RegularExpressionValidator>

<asp:TextBox ID="ConfirmEmail" runat="server" Height="18px" Width="304px" CssClass="textEntry"></asp:TextBox>
<asp:RequiredFieldValidator ID="ConfirmEmailRequired" runat="server" ControlToValidate="ConfirmEmail" CssClass="failureNotification"
     ErrorMessage="Confirm E-mail is required." ToolTip="Confirm E-mail is required." 
     ValidationGroup="AddschoolValidationGroup">*</asp:RequiredFieldValidator>
<asp:CompareValidator ID="EmailCompare" runat="server" ControlToCompare="Email" ControlToValidate="ConfirmEmail" 
      CssClass="failureNotification" Display="Dynamic" ErrorMessage="E-mail and Confirm E-mail must match."
       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，以及Asp.net验证控件和两个图像按钮，一个名为cancel，另一个名为submit。当我单击submit时，我想使用验证控件验证表单并引发事件submit单击。当我单击cancel时，我想引发事件cancel单击。有人能解释一下当我单击submit‘image button’时如何验证表单。

添加ValidationGroup onImageButton ID=提交：

在按钮中设置CausesValidation=True将使您达到目的。

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