How do I set a default value in a UI Forms field using a macro on create?

2025/02/11 2:54 PM

I have got a UI edit form for a custom module class with a UserID as one of the fields. This field uses a selector using a dropdown with the users in the database.

What I want is setting the default value to the current UserID, and preferably not showing the selector at all, only for administrators.

I cannot figure out how to do this. Tried a bit with Macro's but that didn't work. Of course I browsed through the docs, but couldn't find any help there.

In your "Create" class for your custom module you can override the SetFormData(infoObject, IFormFieldValueProvider) method.

Something like so:

protected override Task SetFormData(ProductModelInfo infoObject, IFormFieldValueProvider fieldValueProvider)
{
    // default the order to be last in the list
    var productType = ProductModelInfo.Provider.Get()
        .Column(nameof(ProductModelInfo.ProductModelOrder))
        .OrderByDescending(nameof(ProductModelInfo.ProductModelOrder))
        .FirstOrDefault();
        
    // set the order of the new item to order + 1
    if (productType != null) infoObject.ProductModelOrder = productType.ProductModelOrder + 1;

    return base.SetFormData(infoObject, fieldValueProvider);
}
