Multilingual widget designer

Posted by Community Admin on 13-Jul-2012 00:00

Hi

I have a widget designer that contains a PageField that sits on a multilingual site. When I drop my control on a multilingual page I need to select a page from a localized list of pages but only see the structure for the default language.

I notice the PageField has a RootNodeID property which I guess if set will control this. Could you tell me the correct way of getting a localized root page?

Thanks

Hello Brin,

Actually, the culture is set on InitializeControls() as following:

protected override void InitializeControls(GenericContainer container)

base.DesignerMode = ControlDesignerModes.Simple;

base.AdvancedModeIsDefault = false;

if (this.PropertyEditor != null)

var uiCulture = this.PropertyEditor.PropertyValuesCulture;

this.PageSelectorControl.UICulture = this.PagesSelectorControl.UICulture = uiCulture;

var constantFilter = CommonMethods.GenerateSpecificCultureFilter(uiCulture, "Title");

if (!String.IsNullOrEmpty(constantFilter))

this.PageSelectorControl.ConstantFilter = this.PagesSelectorControl.ConstantFilter = constantFilter;

this.PageSelectorControl.AppendConstantFilter = this.PagesSelectorControl.AppendConstantFilter = true;

Since PageField contains a Page selector, you can access the PageSelector and set its UI culture through the UICulture property. Note that after that, we use the GenerateSpecificCultureFilter() method to filter pages, depending on the culture, specified in the query string. You need to implement your own filtering, based on this method in order to filter pages:

internal static string GenerateSpecificCultureFilter(string uiCulture, string propertyName)

string result = null;

var appSettings = Abstractions.AppSettings.CurrentSettings;

if (appSettings.Multilingual)

var filterBuilder = new System.Text.StringBuilder();

filterBuilder.AppendFormat("(0[\"1\"] != null", propertyName, uiCulture);

if (uiCulture == appSettings.DefaultFrontendLanguage.Name)

filterBuilder.AppendFormat(" OR (0[\"\"] != null", propertyName);

var availableLangs = appSettings.DefinedFrontendLanguages.Select(l => l.Name);

foreach (var lang in availableLangs)

filterBuilder.AppendFormat(" AND 0[\"1\"] = null", propertyName, lang);

filterBuilder.Append(")");

result = filterBuilder.ToString();

return result;

Hi

Thanks for your response, however the PageField does not contain properties named UICulture, ConstantFilter or AppendConstantFilter.

The PageField has been set up as follows:

You mention that the PageField contains a PageSelector however this is internal so not accessible by the designer. Any thoughts?

Thanks again

Brin

Hi Brin,

Excuse me for misleading you. Actually, since you're developing a designer you can directly use the PageSelector control directly in it (no need of a field control). I have provided some additional information on the subject in your support ticket.
