SelectionFactory set Initial/Default value and display it's placeholder in select/dropdown box

Hi all,

I found this topic here - https://world.episerver.com/forum/developer-forum/-Episerver-75-CMS/Thread-Container/2014/9/Setting-a-ISelectItem-as-selected/ - but none of the solutions solves my problem.

I have this property on a page, which uses custom Selection Factory.

And I want to set initial value and display it's placeholder (in admin view, under "All properties" view while creating new page) here in a select box. I do it like this:

// CustomSelectionFactory.cs:

public IEnumerable<ISelectItem> GetSelections(ExtendedMetadata metadata)
{
    List<SelectItem> result = new List<SelectItem>()
    {
        new SelectItem() { Text = "All", Value = null }
    };

    List<CustomSelectItem> customSelectItems = new List<CustomSelectItem>();

    switch (metadata.PropertyName)
    {
        case "DocumentCountry":
            customSelectItems = Api.GetCustomSelectItems(1).Result; 
            break;
        case "DocumentLanguage":
            customSelectItems = Api.GetCustomSelectItems(2).Result; 
            result.RemoveAll(x => x.Text == "All");
            metadata.InitialValue = "1";
            break;
    }

    foreach (CustomSelectItems customSelectItem in customSelectItems)
    {
        result.Add(new SelectItem()
        {
            Text = customSelectItem .Name,
            Value = customSelectItem .Id.ToString()
        });
    }

    return result;
}

// CustomPage.cs

[Display(Name = "Document Country")]
[SelectOne(SelectionFactoryType = typeof(CustomSelectionFactory))]
public virtual string DocumentCountry { get; set; }

[Display(Name = "Document Language")]
[SelectOne(SelectionFactoryType = typeof(CustomSelectionFactory))]
public virtual string DocumentLanguage { get; set; }

Help appreciated!

Hi,

You can set the default value.

public override void SetDefaultValues(ContentType contentType)
{
    base.SetDefaultValues(contentType);
 
    //Set values here
 
}

Ok, now this worked (even without setting "metadata.InitialValue = "1";" in "CustomSelectionFactory.cs", the issue was probably because "DocumentLanguage" property was of type "int?". Thank you!

@Ravindra S. Rathore,

I think I have tried it and it partly works - on publish it passes further the default value, but the placeholder of selectbox is still empty

Placeholder in CMS or on the front-end site?

In admin view, under "All properties" view while creating new page, so I guess it's CMS? :D
