Custom controls everywhere
01 Σεπτεμβρίου 10 03:22 μμ | tolisss | 0 σχόλια   

eXpand have AdditionalViewControlsProvider module that has been design to allow you to add custom controls on a predefined position (Bottom,Top) using its logic architecture ruling system We wanted to add some power to it so in eXpand v10 one is able to position its custom controls any where in the view by setting the rule position to DetailViewItem Then use the Model editor to create an additionalviewcontrol detailview item Associate them with a rule like and finally use the Layout Designer to place them at any position in the View!!! so when you go to the specified view since your rules can be activated uppon any logic your controls visibility will be setup accordingly

The AdditionalViewControlsProvider Module
19 Μαρτίου 10 08:51 πμ | tolisss | 0 σχόλια   

  AdditionalViewControlsProvider is a module that it only knows how to display a given control in a given position . So one could easily define an interface for the parameters needed when this behavior is implemented as public interface IAdditionalViewControlsRule : IConditionalLogicRule {     string Message { get ; set ; }     string MessagePropertyName { get ; set ; }     Type DecoratorType { get ; set ; }     Type ControlType { get ; set ; }     AdditionalViewControlsProviderPosition AdditionalViewControlsProviderPosition { get ; set ; }     bool UseSameIfFound { get ; set ; } } take a note that I inherit IConditionalLogicRule   thus logic engine can evaluate

ModelArtifactState - AdditionalViewControls breaking changes
14 Μαρτίου 10 08:09 μμ | tolisss | 0 σχόλια   

I have been pretty silent the last few weeks , but I have not been lazy so eXpand has now many more modules and features that I am going to speak about in my next posts. A Logic Module has been implemented and that lead to some breaking changes to ModelArtifactState / AdditionalViewControlsProvider modules ModelArtifactState The previous schema of ModelArtifactState rules was like < ModelArtifact >     < ConditionalControllerState IsNewNode = " True " >       < ControllerStateRule ID = " tests " TypeInfo = " DevExpress.ExpressApp.SystemModule.AboutInfo " IsNewNode = " True " />     </ ConditionalControllerState >   </ ModelArtifact >

Since I got many complaints about the low resolution of my videos I am on a search for a better video hosting service than YouTube. Robert suggested to use Silverlight service at Blogger Video embedding resolved but this one looks the same as YouToube. After spending some more time on researching on this I came across http://blip.tv/ excellent hosting service To get an idea how good they are I suggest you read their FAQs They accept almost all kinds of  Videos They are free They do not change the video after uploading The customization of the video playback controls is unlimited . You can configure almost anything on their well design interface I am going to use that excellent service to republish my videos So if you want to see those videos again in good

Bend Xaf Applications with Model Artifact State Module

How many times have you said “What a great pattern MVP is!!!” Look for example how is implement the hint engine of main Xaf demo. I will try to explain that implementation. Controllers There is a windowcontroller called AdditionalInfoController and from it 2 controllers derive WebShowAdditionalInfoController and WinShowAdditionalInfoController. What they do? they enable inserting any kind of control as the first control of a view. They are the engine, they implement a behaviour and they also serve as the Observer design pattern Observer pattern: Define a one-to-many dependency between objects so that when one object changes state, all its dependents are notified and updated automatically. I am going to refactor the code from the main demo and create 3 new modules
