I have this ValidationExpression="(d{1,}.{0,2} .{2,})|(.{2,} d{1,}.{0,2})" used in regularexpression validator. I want to use the same one in a customvalidator. But customvalidator does not have option validationexpression. how can i add this in code or in tag.
View 1 RepliesI want to exclude spaces when validating a textbox in vb.net.

I am using the CustomValidator for the first time but it doesn't seem to be firing DateExpireRequired_ServerValidate and just runs the code in the Click action.Been bugging me for a couple hours now! can anyone see a problem with what im doing?The DropDownList in my code below is populated using Roles.GetAllRoles()
ASP.NET
<asp:Label ID="lUserRole" runat="server" AssociatedControlID="tUserRole">User Role:</asp:Label>
<asp:DropDownList ID="tUserRole" runat="server" CausesValidation="True">
</asp:DropDownList>
[code]....
I have a CustomValidator that checks if text entered in textboxes matches certain fields in a database. This was all working great before, but I have modified my page quite a bit since then and it is no longer working. I didn't think I changed anything that would affect this, but apparently I did. All my other validators (required field validators) are working correctly, but my CustomValidator isn't responding.So anyway, here is my code:
CustomValidator:
<asp:CustomValidator ID="CustomValidator1" runat="server" ControlToValidate="txtCoursePrefix" ErrorMessage="Course number is already taken."></asp:CustomValidator>
[code]....
Everything is working up until CustomValidator1.SetFocusOnError = True and args.IsValid = False. I have tested the If statement and it's working correctly, it returns true and anything else I put inside of it executes.
I know this has been asked a lot, but I have a server-side custom validator that is not being fired, and I cannot find why (also, I've copied examples that work from other places and cannot make it work...)
The code:
<asp:CustomValidator ID="MyValidator" runat="server" ErrorMessage="My error message" OnServerValidate="MyValidator_OnServerValidate" />
Validate function

EDIT 2: Added a Page.validate() on my button code, and it does not call the server side of the validator.Also, the custom validator is being called (at least the client/javascript side of it, but not the server side)
Writing a custom validator for a dropdownlist that is using autopostback. Seems to ignore the validation altogether. Why is it ignored and is there an easy fix? Note I did not use ControlToValidate
asp.net:
<asp:UpdatePanel ID="updatePanel" runat="server" UpdateMode="Conditional" Visible="true" RenderMode="Inline">
<ContentTemplate>
<asp:DropDownList ID="ddlCommandAssign" runat="server" AutoPostBack="true">
</asp:DropDownList>
[code]....
For debugging purposes, I want it to fail every time.It doesn't seem to be executing the behind code at all. For debugging, I added the line response.redirect("dummy.html") ... which never gets called, which also indicates (I think) that the validator never gets called.
I have a radiobuttonlist with two items, Yes or No. The radiobuttonlist control has a customvalidator that needs a servervalidation function and a javascript clientvalidationfunction. Could you help me? The function in this message works but only when i actually have choosen one of the two listitems, when no listitem is selected the validation skips my radiobuttonlist control.
function ValidateRadioButtonList(source, arguments) {
var RBL = document.getElementById(source.controltovalidate);
var radiobuttonlist = RBL.getElementsByTagName("input");
var counter = 0;

I have a form with contains, among others, a TextBox called "wmi_cell_phone" and a RadioButtonList "wmi_send_sms". Basically, I need to create a validator that checks whether the value of the selected radio is "Y". If this is the case, then it checks if the TextBox value is empty or not. If it is empty, then it should notify the user to enter a value.
