我做了一个小表来允许编辑、删除和插入记录:
表格(DataGridView,绑定)很简单:单击编辑进入“编辑”模式(提供“取消”),输入新值并单击“添加”插入新记录。
每个字段都有一组规则(在 x 和 y 之间,都是数字),因此它们与 MaskedEditExtender 和 MaskedEditValidator 相关联:
(第 1 列的示例):
<asp:TemplateField HeaderStyle-HorizontalAlign="Center" ItemStyle-HorizontalAlign="Right" FooterStyle-HorizontalAlign="Right" HeaderText="First bus #">
<ItemTemplate>
<asp:Label runat="server" ID="BusIdStartLabel" Text='<% #Bind("BusIdStart","{0:D4}") %>' />
</ItemTemplate>
<EditItemTemplate>
<ajaxToolkit:MaskedEditExtender runat="server" ID="BusIdStartTextBoxMaskedEditExtender" TargetControlID="BusIdStartTextBox" BehaviorID="EditBusIdStartTextBoxBehavior"
MaskType="Number"
Mask="9999" PromptCharacter=" "
InputDirection="RightToLeft"
OnInvalidCssClass="maskedEditError" OnFocusCssClass="maskedEditFocus"
AutoComplete="False" ErrorTooltipEnabled="True" MessageValidatorTip="False" />
<ajaxToolkit:MaskedEditValidator runat="server" ID="BusIdStartTextBoxMaskedEditValidator" ControlToValidate="BusIdStartTextBox" ControlExtender="BusIdStartTextBoxMaskedEditExtender"
MinimumValue="0" MaximumValue="9999"
IsValidEmpty="False" Display="None"
InvalidValueMessage="Enter a value between 0000 and 9999"
MaximumValueMessage="Enter a value between 0000 and 9999"
EmptyValueMessage="Enter a value between 0000 and 9999" />
<asp:TextBox runat="server" ID="BusIdStartTextBox" Text='<% #Bind("BusIdStart","{0:D4}") %>' Width="2.5em" Height="13px" CssClass="rightAlignTextBox" />
</EditItemTemplate>
<FooterTemplate>
<ajaxToolkit:MaskedEditExtender runat="server" ID="BusIdStartTextBoxMaskedEditExtender" TargetControlID="BusIdStartTextBox" BehaviorID="FooterBusIdStartTextBoxBehavior"
MaskType="Number"
Mask="9999" PromptCharacter=" "
InputDirection="RightToLeft"
OnInvalidCssClass="maskedEditError" OnFocusCssClass="maskedEditFocus"
AutoComplete="False" ErrorTooltipEnabled="True" MessageValidatorTip="False" />
<ajaxToolkit:MaskedEditValidator runat="server" ID="BusIdStartTextBoxMaskedEditValidator" ControlToValidate="BusIdStartTextBox" ControlExtender="BusIdStartTextBoxMaskedEditExtender"
MinimumValue="0" MaximumValue="9999"
IsValidEmpty="False" Display="None"
InvalidValueMessage="Enter a value between 0000 and 9999"
MaximumValueMessage="Enter a value between 0000 and 9999"
EmptyValueMessage="Enter a value between 0000 and 9999" />
<asp:TextBox runat="server" ID="BusIdStartTextBox" Width="2.5em" Height="13px" CssClass="rightAlignTextBox" />
</FooterTemplate>
</asp:TemplateField>
问题:单击表单的任何链接(编辑、删除)都会触发对所有内容的验证。因此,单击“编辑”会触发“插入”行的验证(返回“无效”)。我想我会用这个禁用它:
<asp:LinkButton runat="server" ID="ActionEditLink" CommandName="Edit" Text="Edit" OnClientClick="DeactivateValidation()" />
...
function DeactivateValidation() {
TryDispose('EditBusIdStartTextBoxBehavior');
TryDispose('FooterBusIdStartTextBoxBehavior');
//etc.
}
function TryDispose(behaviorId) {
var behavior = window.$find(behaviorId);
if (behavior != null)
behavior.dispose();
}
但是验证之后仍然处于活动状态并阻止链接。我如何真正停用客户端的验证?
