我有一个下拉列表,在未隐藏时应该是必需的,所以我有一个RequiredFieldValidator。
<table runat="server" id="tblLocations" class="ts1">
<tr>
<td class="tr0">
Location:
</td>
<td>
<asp:DropDownList ID="ddlLocations" runat="server">
</asp:DropDownList>
<asp:RequiredFieldValidator ID="rfvDdlLocations" runat="server" ControlToValidate="ddlLocations" InitialValue="0" validationgroup="LocationValidation" ErrorMessage="Please select a Location" />
</td>
</tr>
</table>
选择单选按钮后,我将此表的可见性设置为false。
我想在不可见时禁用此字段的验证,因此我在单选按钮更改事件上设置了此项:
rfvDdlLocations.Enabled = tblLocations.Visible;
但是,这并不会禁用验证。
我尝试过使用其他地方建议的JQuery,但这也没有效果:
<script type="text/javascript">
$("[id$='btnDelegate']").click(function () {
if (!$("[id$='tblLocations']").is(':visible')) {
ValidatorEnable($("[id$='rfvDdlLocations']")[0], false);
}
//ValidationSummaryOnSubmit("LoginUserValidationGroup");
if (Page_ClientValidate("LocationValidation")) {
alert('it is valid');
return true;
}
else {
alert('Not valid');
return false;
}
});
答案 0 :(得分:1)
在这种情况下你应该使用customvalidator,如下所示
<asp:CustomValidator ID="cvDdlLocations" runat="server" ControlToValidate="ddlLocations" ValidationGroup="LocationValidation" ErrorMessage="Please select a Location" OnServerValidate="cvDdlLocations_ServerValidate" ClientValidationFunction="validateLocation" />
并进行客户验证
function validateLocation(s, args) {
if($('#'<%= Radio.ClientID %>).is(':checked')){
args.IsValid = true;
}
else {
args.IsValid = $('#<%= ddlLocations.ClientID%>').val() != "0";
}
}
和服务器验证
protected void cvPrice2Edit_ServerValidate(object source, ServerValidateEventArgs args)
{
args.IsValid = true;
if(!Radio.Checked) {
args.IsValid = ddlLocations.SelectedValue != "0";
}
}
我希望这会有所帮助
