custom-validators

I have two TextBox controls for start date & end date input. I have to validate that end date is not greater than start date & the difference between start date & end date is not more than 12 months. You will have to use a CustomValidator to do this. In your markyou, you will have something like this: <asp:TextBox ID="txbStartDate" runat="server" /> <asp:TextBox ID="txbEndDate" runat="server" /> <asp:CustomValidator OnServerValidate="ValidateDuration" ErrorMessage="Dates are too far apart" runat="server" /> And in your code behind, you define the validation handler: protected void

Maybe it's just the way my mind works, but I have a very hard time understanding how you're supposed to do custom unobtrusive validators. The C# part is easy enough, but the jqueryui adapters are where i get lost. I've been trying to make a validator that requires a date to be a certain amount of time in the past. I use this for age validation, to make sure someone has entered a date that is 18 years in the past. I finally decided to just make it a remote validator, that way the validation uses the same code both client and server side. Still, i'd be interested in the jquery to make this work.

I come to you for talking about a problem with angular material. In fact, I think it's an issue, but I prefer looking for a misunterstanding first. The first thing about my problem is the context, i try to do a simple form containing two inputs : a password and its' confirmation. user-form.component.ts this.newUserForm = this.fb.group({ type: ['', Validators.required], firstname: ['', Validators.required], lastname: ['', Validators.required], login: ['', Validators.required], matchingPasswordsForm: this.fb.group( { password1: ['', Validators.required], password2: ['', Validators.required], },
