Are you getting this error on Sitecore 9 Forms Submission? I got it and it took me some time to figure out. It’s all related to Validation. Here are the points to check to narrow down the issue —
If you have form fields set it to mandatory, change it to optional and see if that makes the submission successful. If so, one of the field validation is causing trouble.
It happens for custom form control quite often, where you need add the validation to razor view file and make sure you have this attribute – GenerateUnobtrusiveValidationAttributes.
Compare your custom control razor file to any one of inbuilt form controls ([iis-site-folder]\Views\FormBuilder\FieldTemplates ) like below and if you see any difference on attributes, add it out.
Finally a simple check: make sure to publish all the forms and view the landing page in live mode(not in preview mode)
I came across a requirement from a client that they wanted to show Country and it’s states grouped in a dropownlist. I created a custom grouped dropdown to fit into the scenario. Since this is an extension of dropdownlist, no speak knowledge required.
Let’s get started
Step 1: Create custom dropdown list
Create a custom dropdownlist under /sitecore/system/Settings/Forms/Field Types/Lists based on Field Type(/sitecore/templates/System/Forms/Field Type) template like below
Step 2: Create a code behind class and razor view
create a code behind class like this in VS project
using System.Collections.Generic;
using Sitecore.Data.Items;
using Sitecore.Diagnostics;
using Sitecore.ExperienceForms.Mvc.Models.Fields;
namespace Sitecore.Project.Example.Views.StateDropdown
{
public class StateDropdown : DropDownListViewModel
{
protected override void InitItemProperties(Item item)
{
Assert.ArgumentNotNull(item, nameof(item));
base.InitItemProperties(item);
}
protected override void UpdateItemFields(Item item)
{
Assert.ArgumentNotNull(item, nameof(item));
base.UpdateItemFields(item);
}
public Dictionary<string, Dictionary<string, string>> Regions()
{
if(string.IsNullOrEmpty(DataSource)) return new Dictionary<string, Dictionary<string, string>>();
Dictionary<string, Dictionary<string, string>> counrtyCollection = new Dictionary<string, Dictionary<string, string>>();
Item item = Context.Database.GetItem(DataSource);
var children = item.GetChildren();
foreach (Item child in children)
{
counrtyCollection.Add(child.Fields["Name"].Value, new Dictionary<string, string>());
foreach (Item desc in child.Children)
{
counrtyCollection[child.Fields["Name"].Value].Add(desc.Fields["Name"].Value, desc.Fields["Code"].Value);
}
}
return counrtyCollection;
}
}
}
Create a razor view like this and build project
@using Sitecore.ExperienceForms.Mvc.Html
@model Sitecore.Project.Example.Views.StateDropdown.StateDropdown
@{
var regions = Model.Regions();
}
<label for="@Html.IdFor(m => Model.Value)" class="@Model.LabelCssClass">@Html.DisplayTextFor(t => Model.Title)</label>
<select id="@Html.IdFor(m => Model.Value)" data-trigger name="@Html.NameFor(m => Model.Value)" class="@Model.CssClass" placeholder="Select Your Work Location" data-sc-tracking="@Model.IsTrackingEnabled" data-sc-field-name="@Model.Name" @Html.GenerateUnobtrusiveValidationAttributes(m => m.Value)>
<option placeholder>Select Your Work Location</option>
@foreach (var region in regions)
{
<optGroup data-id="@region.Value" label="@region.Key">
@foreach (var state in region.Value)
{
<option value="@state.Value">@state.Key</option>
}
</optGroup>
}
</select>
@Html.ValidationMessageFor(m => Model.Value)
Step 3: Fill out the fields
Fill out the View Path, Model Type and Property Editor(should be Property Editor Settings/DropDown List).
you are now all set to utilize the custom dropdown list in Forms Designer. Don’t forget to publish the field!
Hope this is helpful. Any questions, please leave a comment.
I came across a scenario where i implemented a custom validation on Sitecore 9 Forms. Sharing my knowledge here. You can achieve this in three simple steps.
Step 1: Create custom validator
Create a custom validator under /sitecore/system/settings/forms/validation based on Validation(sitecore/templates/System/Forms/Validation) template like below
Step 2: Fill out the fields
Fill out your own regex and error message. You can copy the Type value from other validator.
Step 3: Assign the custom validator
You can now add the new custom validator to any Form fields( /sitecore/system/Settings/Forms/Field Types). All set and no code required!

I have Sitecore 9.1 instance and today my sitecore license file expired. I had to replace the license.xml in multiple places to make sure my site, xConnect and Identity Server sites work.
Have you submitted a form and it returned with this error ‘The required anti-forgery cookie “__requestVerificationToken” is not present’? If so, here is the resolution.
This could be because of caching. Can you check if your rendering component or container/page level caching check box is checked? if so, unchecking the caching will fix the issue.
Also here is quick check you can do to see whether your form is cached – Inspect the form and check the _requestverificationtoken value like below and refresh the page – do you see same value now? if so, your form is in cache!
I’m participating in Sitecore Hackathon for the first time this year. One of the requirement is to have sitecore 9.1(Initial version) installed on your machine.

DB:
Microsoft SQL Server 2017 or 2016 SP2 – Supports the XM database and is the required for the xDB

IIS 10
. NET
Sitecore XP 9.1.0 requires .NET Framework 4.7.1
Sitecore Identity server requires .NET Core Runtime 2.1.3
You must apply any available updates to the .NET Framework on every Sitecore installation
Search Indexing
Solr 7.2.1 – Default search provider
Azure Search – supported and recommended for Azure Cloud PaaS deployments only
Lucene – Only supports content search and does not support xConnect.
Powershell 5.1 – for Installing SIF
Preparation:
Download installation package(XP Single) from here
Extract the zip file you just downloaded
Again extract this file – XP0 Configuration files 9.1.0 rev. 001564.zip
Copy your license.xml file (If you have enrolled for Hackathon, you should have received the file in email)
Update the following files in the folder with the exact information – solr path, solr service name, configsets path, instance name for sitecore, SQL instance name and login credentials.
This is a proctor guided exam, no book allowed. Also, the exam software Senitel says you should have an external web camera. It worked with the in-built camera on my work computer. So don’t worry about the external camera.
The exam has 50 questions and 90 minutes to complete. You can review the answers as many times as you want. I completed the exam in 30 minutes and review the answers in the next 30 minutes and I still have 30 more minutes left!
Overall I got a 88% score. Here is my Topic level scoring:
Architecture: 100% Creating and Editing Items: 100% Development Environment: 75% Docs and Support: 100% Installation: 100% Publishing: 100% xManagement: 100% Field Types: 83% Media: 100% Templates: 85% Versioning: 100% Presentation: 77% API: 100% Modules and Packages: 100% Performance: 100% Search: 80%
Once you complete you exam, you will receive an email from test center with score and certification pdf file. Good luck!
