Resync designer view with model/view state

Posted By:      Posted Date: September 10, 2010    Points: 0   Category :Windows Application
Hi, In most cases, changes made to the model or view state pretty much immediately reflect in the designer UI, assuming there is a corresponding UI representation for the model item or view state.  What I'm doing is using the view state to establish links (in a Flowchart designer) between activity designers.  Normally this works fine.  But occasionally, an exception is thrown saying that a connection cannot be made between two points.   In the event of this exception, I can wrap the statement that throws the exception (in my case, EditingScope.Complete) and retry the logic, this time not specifying the connection points and letting the designer's routing algorithm comes up with its own path.   The problem I'm experience is when I wrap the call (EditingScope.Complete) in a try/catch block that throws the exception and re-do the connection logic, this time not specifying the view state (but still specifying the Next property of a FlowStep, or True/False property of a FlowDecision, etc using the ModelItem.SetValue method), visually a connection is not made between the activities.  But if I manually close the designer and reload it or use the bread crumb navigation to move away from the current designer and then return, the connections visually appear. I want to be able to programmatically refresh the UI based on the updated model / view st

ASP.NET 2.0: Speed Up Your Site with the Improved View State in ASP.NET 2.0


View state is a wonderful thing. It allows the ASP.NET developer to maintain state for server-side controls that are not form elements.Used judiciously, it can improve the user experience. But in the wrong hands, it can cause your pages to grind to a halt. The release of ASP.NET 2.0 will include a variety of improvements to view state that will make it easier to use and less likely to slow performance.

Entity Data Model and database view returning the same columns as there are in a table


When adding a stored procedure into the Entity Data Model I can select whether the procedure returns a scalar, a (new) complex type or one of the entity types I already defined. 

How do I do something similar for a view?

I mean assuming I have a view like this

CREATE VIEW FilteredFoos as SELECT Foo.* FROM Foo join ... WHERE ...

(that is a view that implements some involved filtering, but returns all columns from one table) how do I add it to the project so that I can use the entity set, but get the Foo objects, not some new FilteredFoo objects.

var foos = myDB.FilteredFoos.Include("Bar").ToList();

foreach (Foo foo in foos) { ...

Thanks, Jenda

How to create scrolling table for columns in a SharePoint Designer Data View


I have a fairly complex SharePoint Designer 2007 Data View they have added two more requirements.

1. Have the columns on the right side be able to scroll left to right as there is a large number of columns, while the first 3 columns on the left side stay locked in place.  This is only one list not two, and because of some other requirements I have it must remain to be just one list.

2. Then they also need to have scrolling up and down of the entire list with the headers locked in place.

The first requirement is more important than the second, but preferrably I need to do both.

I am new to XSL so not familar with the syntax. Is this something I can do on a custom Data View? Does anyone have any examples of how?

I have a drawing that show how it needs to look but I don't see an option here to upload a graphic.

So here is a link to my graphic example uploaded to my blog area: http://lindachapman.blogspot.com/  or just the image here: http://4.bp.blogspot.com/_aB01ue__NvQ/TGL42MOvrGI/AAAAAAAAAA4/c3xP4uCy4BU/s1600/Scrolling.png
