Lookup Item Sorting, Multi-Value Filters, Login Control Localization

Several core framework fixes were released to address some urgent issues.

  • Project Wizard will enforce the port used by IIS Express to test applications to be above 1100. The port is assigned randomly. Lower range port value requires running IIS Express in administrative mode.
  • Dedicated page Login.aspx is now based on YOUR_NAMESPACE.Web.PageBase class to ensure that its content is being localized.
  • The bug that prevents selection of multi-value filters has been fixed.
  • New enhancement has been introduced to the processing of items displayed by lookups with styles Drop Down List, List Box, Radio Button List, and Check Box List based on data controllers.

    Previous implementation has sorted values by the field name specified in Data Text Field property of the lookup field. This may be undesirable if a specific order of items is required.

    Going forward the order of items will depend on the grid view of the lookup data controller. Simply set the Sort Expression of the grid view to a desired combination of fields and use asc|desc to indicate the order as you would do in a SQL statement selecting data.

We are planning to release another update shortly after the 4th of July.

Highlighting “Past Due” and “Within” Data Rows

Code On Time generates applications that can be styled with CSS rules to adjust logo, background, and provide conditional formatting of the data views.

The latest enhancements to the client library allow creating complex rules that depend on current date and time.

The screenshot below shows a list of orders from the Nortwhind database sample presented in a Data Sheet view. Conditional styling rules are applied to the view.

The second row from the top has a pink “FiveDays” background since the required date for this order is 7/2/2011 and the date in the screen shot is 6/28/2011, which places the order within five days of the required date.

There are four rows with red background. The “PastDue” background is applied to these rows since the first row has been shipped after the required date and the other three were not shipped.


Here is how you can set this up in your own application.

Start the code generator, select your project, click Design button, activate All Controllers tab and locate your controller.

Select the controller and activate Views tab.

Select view grid1 and activate Styles tab.

Enter two styling rules shown in the picture


The test formulas shown below are referring to the Orders table from the Northwind sample.

Css Class Test
FiveDays [ShippedDate] == null && Date.$within([RequiredDate], 5)
Past Due Date.$pastDue([ShippedDate], [RequiredDate])

Tests are written in JavaScript. Data controller field names are specified in square brackets. The client library will substitute references to the fields names with calls to a function that will return the field values. The expressions will be evaluated for each data row to see if a custom CSS class must be assigned to the table row.

Client Library extensions to the Date class are being used to test the dates. The extensions are Date.$within and $Date.pastDue.

Exist the designer and generate your application. Open your project in Visual Studio via File | Open Website option if your app is a Web Site Factory project or File | Open Project if your app is a Web App Factory project.

Add new CSS style sheet in your project under the ~/App_Themes folder.


Double click your new style sheet and enter the following CSS rule.

.FiveDays td.Cell
    background-color: #FFCCCC!important;
    color: Black !important;

.PastDue td.Cell
    background-color: #CC3300!important;
    color: Black !important;

It is very important to use “!important” after the CSS property values to override the default style sheets of your application.

Run your application in a web browser and make sure to hit the refresh button to ensure that the styles are taking effect.

Custom Date Formats, Designer History

Code On Time has released another update that solves the following issues:

  • Designer got its memory back. Filters, selected record, page, and sort order are automatically restored as you navigate between configuration properties of project objects.
  • Custom date formats such as dd-MMM-yyyy and MM-yyyy, dd are now handled correctly by the client library. Standard data formats native to the selected UI culture are handled automatically and require no configuration. Custom date format parsing has been broken in the last release.
  • External filter values are now available to business rules in the native “typed” form. The previous release has been passing external values as “typed strings”.
  • Additional localized resources for no, nl, and sv cultures have been included in the code generation library.

We are working on the localization tutorial and hope to make it available in a day or two.
