Episerver Forms Conditional Validation
Don't know if this is too late for you, but this URL has the info you need:
https://www.wearediagram.com/blog/improving-episervers-content-editing-experience-through-validation
https://gist.github.com/fredrikhaglund/44d494d04e2ffd4e8cbd
In my case:
public IEnumerable<ValidationError> Validate(HomePage instance)
{
if (instance.FooterSettings.ShowChannelOne)
{
if(String.IsNullOrEmpty(instance.FooterSettings.ChannelOneURL) || instance.FooterSettings.ChannelOneIcon == null ||
instance.FooterSettings.ChannelOneHover == null || String.IsNullOrEmpty(instance.FooterSettings.ChannelOneTooltip))
{
return new[]
{
new ValidationError
{
ErrorMessage = "Mandatory to fill out rest of Channel 1 fields (URL, Icons * 2, Tooltip)",
PropertyName = "ShowChannelOne",
Severity = ValidationErrorSeverity.Error
}
};
etc....

Currently struggling with a piece of functionality on an Episerver implementation.
Basically I need to implement conditional validation on an Episerver Forms field. E.g. TextBox2 is required is TextBox1 has a value of 1, but is not required when TextBox1 has other values.
I have looked into custom validators but I am unclear how I might extend the validator to have additional properties for the field name I want to target and the value it should have in order for the validation to perform the check.
If anybody has any insight on achieving this it would be appreciated.
Thanks
