Changing Upload Size Limit

Code On Time automatically handles file uploading and downloading for blob fields. However, ASP.NET limits file upload size to 4 MB by default. When a user attempts to upload a larger file, an error will be thrown.

Error message showing that max request length is exceeded.

Let’s change the file size limit in order to allow for larger files to be uploaded.

Start the web application generator. Click on the project name, and select Settings. Press Web Server Configuration.

In the Web.Config modification instructions, insert the following:

SetAttribute: /configuration/system.web/httpRuntime
maxRequestLength: 102400

The maxRequestLength value is the size limit in KB.

Press Finish, and continue to regenerate the web application. When a file larger than 4 MB is uploaded, the upload will no longer throw an error.

File upload has been successful.

Many-To-Many, Project Locations and Groups

Release 8.7.3.0 introduces support for user-defined projct locations and project groups. There is also a set of improvements in many-to-many field handling in forms and inline editing mode. The application framework has been refactored to support addons. For example, release 8.8.0.0 will support Offline Sync Add-On.

Many-to-Many Fields

Inline editing of many-to-many fields is fully supported in the release on mobile and desktop devices.

Inline editing of a many-to-many field in a Touch UI app.

The application generator now handles the following implementations of many-to-many tables. Tables EmployeeTerritories, EmployeeTerritories2, and EmloyeeTerritories use compound, identity-based, and GUID –based primary keys.
Various configurations of primary keys for many-to-many field implementation supported in Code On Time and Touch UI.

Here is an exampl of Check Box List presentation of the field. The previous screen shot shows “basket” implementation with Auto Complete.

Project Locations and Groups

New Project screen of the app generator has changed and allows specifying an arbitrary project name and project location. Developers can change the display name and group directly on the Namespace & Framework page of the Project Wizard. The start of the app generator will group projects and have them displayed alphabetically within a group. There is also a “top 5” or rather “last changed” projects rendered in a dedicated group at the top of the start page. If the number of projects is less than 10 then “top 5” are not presented.

The start page of Code On Time displays groups of projects.

This is the new version of the New Project screen. Note that if the Visual Studio is installed on your development machine then the Location is automatically set to [User Profile]\Source\Repos folder. The new app will also be configured to use Git for source control.

Cloud On Time

The application framework has been changed to support Cloud Identity, the upcoming membership system based on claims.

If you are using Cloud On Time app for development then make sure to install the latest version. If the app is re-generated then it will become incompatible with the prior releases of Cloud On Time.

Summary of the Release

See release details below:

  • Many-To-Many fields are now compatible with inline editing.
  • Many-to-many fields based on tables with identity, guid-based, and comp0und primary keys now work uniformly correctly.
  • Action with command name Navigate and Result.NavigateUrl will now load in iframe embedded in the virtual Touch UI page if URL starts with “http” . Can force behavior with “_internal:” target, or use "_self" to load current tab, or "_blank" for separate tab.
  • Touch hyperlinks will now open in internal iframe if target = "_internal".
  • Touch UI - Read-only checkbox does not overlap the text of the field footer.
  • Classic UI – Data View property  AutoHighlightFirstRow works correctly with hidden child data views.
  • Classic and Touch UI - Corrected processing of NewValue and OldValue in _findKeyValue method, which was previously causing error when uploading binary data.
  • Project Wizard now captures Display Name and Group on the "Namespace and Framework" page. The same page also provides a link to open the project location.
  • The installer now includes folder ~/Library/_Explorer/Images. This folder was missing from the last release.
  • Cloud Identity request handler is now a part of the framework. Learn about this upcoming feature at http://codeontime.com/roadmap.
  • Framework now implements support for addons. This feature makes possible for us to introduce the first new product called Offline Sync Add-on. The upcoming  Code On Time v9 will be delivered as an add-on.
  • Important fixes to NewValue and OldValue processing are delivered in this release.  Value of the read-only fields is calculated as OldValue if not Modified and as NewValue when Modifed property has been assigned explicitly. Otherwise the OldValue is returned for ReadOnly fields. This addresses numerous issues on the forum in the past week.

Tags are also used to configure the Chart presentation style. All chart tags start with the keyword “pivotX”, with X being the ID of the pivot. Learn more about how to format chart tags.

These keywords must be combined with dashes “-” to form a tag. Note that keywords with “X” require an integer value replacing the X. If not specified, the default value is 0.

Note that keywords can be split into multiple tags. For example, specifying “pivot1-row1-area” will be equivalent to “pivot1-row1 pivot1-area”. Do not specify duplicate keywords for the same pivot.

Some keywords support specifying a string value. This keyword must be the last keyword of the tag. Format these keywords like the following:

pivot1-title:"This is the title"

The table below enumerates the available keywords.

Keyword Function
pivotX The integer value X determines the pivot ID that the properties will be applied to.
rowX The data field will be used as a row. The index of the row is X.
colX The data field will be used as a column. The index of the column is X.
valX The data field will be used as a value. The index of the value is X.
area
areastacked
bar
barstacked
candlestick
column
columnstacked
candlestick
donut

table
This keyword determines the chart type. If this keyword is not specified on at least one tag referencing pivot X, then the pivot will not be rendered as a chart.
small
medium
large
Determines the default size for the chart in the user interface.
topX Only the top X number of rows or columns will be kept. The rest will be hidden.
other When used in combination with “topX”, the hidden rows or columns will be collapsed into an “Other” row or column.
date This keyword, used on a DateTime data field, will compose multiple pivots with different configurations. The pivots tested are: year, year/quarter, year/month, year/month/weekofyear, year/month/day. The pivot with the number of rows closest to 25 will be selected for use.
sum
min
max
avg
count
These keywords will determine the value that will be used when calculating cells.
timeofday
second
minute
halfhour

These keywords determine the date bucket mode. The DateTime value will be parsed and use the relevant part of the date.
all Lookup data fields will select all distinct values from the database and ensure that all possible lookup values will be present in the row or column. DateTime data fields will make sure that each bucket between the first and last row or column will be present.
hideblank The “blank” row or column will be hidden.
sortasc
sortdesc
sortascbyval
sortdescbyval
Use the “sort” keyword to determine the sorting order for values of this row or column. Specify “sortasc” or “sortdesc” to sort the row or column alphabetically or numerically. Specify “sortascbyval” or “sortdescbyval” to sort the rows or columns numerically by the value itself.
