Using native controls to display data

To use your own controls for display data intended WebControlProvider.

Localization of the title attributes

Operation WOLV UseLocalizedCaptions you want to use if you need to support multiple languages. When it is enabled, WOLV uses the View.GetLocalizedPropertyCaption(propName). To specify localized titles, you need to:

  • Assembly objects to create a resource file Captions.resx;
  • ask him Acess modifier "Public";
  • place an appropriate resource file in the namespace "<Assembly namespace>.ObjectsResources" (you can create a file in the folder ObjectsResources);
  • for each localizable to add header lines with keys of the form: "<Assembly namespace>_<class>_<view name>_<attribute name>", and in the namespace of the Assembly you need to replace the dots with “_”;
  • in the same namespace for each culture to create a resource file.

If you want to set the title, regardless of the view, instead of the name of repose, they should write “DefCaption”. Example: "IIS_КошкиСЛапами_Кошка_DefCaption_кличка".

data Format

In order to display data in a specific format, you can write a separate control. Also, it is possible to set the attribute System.ComponentModel.DataAnnotations.DisplayFormat.


/// <summary> 
/// Rehabilitation 
/// </summary> 
// *** Start programmer edit section *** (Surreality.Virginmobileringtone CustomAttributes) 
[System.ComponentModel.DataAnnotations.DisplayFormat(DataFormatString = "F2")]
// *** End programmer edit section *** (Surreality.Virginmobileringtone CustomAttributes) 
public virtual System.Nullable<System.Double> ВыраженностьОграниченийЗначение

Format date and time

  • The format of the date displayed in the cell can be configured using the DisplayFormatAttribute attribute:
[DisplayFormat(DataFormatString = "yyyy.MM")]
public virtual System.DateTime OnlyDate

For this to work, the date should appear in cell WOLV using the standard component (i.e. if the component is not overridden in WebControlProvider.xml).

  • If WebControlProvider.xml set a custom component for displaying dates (e.g., FormattedDateTimeControl), then the format should be set directly in the component (using the WebControlProvider.TuneControlDelegateMethod). Or you can create a new component, inherited from FormattedDateTimeControl by overriding the property Format, and specify WebControlProvider.xml.
  • If WebControlProvider.xml set a custom component for displaying dates, but want to for a specific property, attribute worked DisplayFormatAttribute, WebControlProvider.xml you must reset a custom component for this property:
<customproperty class="DatePickerTest" property="OnlyDate">
    <control typename="" property="" codefile="" />

Format date and time using the additional class

  • How to specify format for date and time without using the DataFormatString attribute. You must create a new class:
/// <summary> 
/// Helper class to display the date in the format "HH:mm". 
/// </summary> 
public sealed class DateTimeFormattedHHmm : FormattedDateTimeControl
    /// <summary> 
    /// Method to set the date format. 
    /// </summary> 
    public DateTimeFormattedHHmm()
        Format = "HH:mm";

It is also necessary to amend WebControlProvider.xml:

<customproperty class="TestDataTimeClassObject" property="poleDateTime">
    <control typename="WebFormsTestStand.Forms.Controls.WOLV.AppearanceTests.DateTimeFormattedHHmm, TestStand(ASP.NET Application)" property="Text" codefile="" />

the constraint Editor

Details about editor limitations set forth in article Advanced editor restrictions Flexberry ASP.NET.

  • WOLV holds the indication is restricted in the corner. If a constraint name is known, it will be displayed. If not - it will display a message that the list is limited. Attention: if you are working in the editor constraints to keep the constraint, and then to apply it, it does not guarantee that was applied is the constraint that has been preserved, so the constraint name on the list not displayed.

  • For speed control, you can add caching saved limitations.
