View 2 RepliesDo we have to do something special to have ASP.NET partial classes aware of controls that are declared in our user control's base classes? The partial classes keep generating declarations for controls in the base class which mean the controls in the base class get hidden and are null.

I am a .NET / C# back end guy. I am working on a app that will have about 200 different data entry screens. For me exposing DTO as a collection for CRUD (IUpdatable and IQueryable) is the easy part, I can do it in my sleep :-). What I am trying to decide is what type of front end technology will allow me to develop these data entry screens fast. They don't have to be fancy but they are not just plain grid either and on average they have about 15 form fields and some client side data validation (no db look up) Options I am looking at are
Use ExtJS on the front and REST / JSON on the back. ASP.NET RIA but I do not know SL (Well XAML) Plain ASP.NET / MVC One idea I had was the DTO will contain the meta data about the form (As Attributes) and the form can be dynamically generated, but I do not want to reinvent the wheel if there is an easier way. I have looked at RAD software but all of them look at the DB and generate screens. I'd rather want something that can look at my DTO and generate screens.
After I developed the system by usin vs2008 , my supervisor asked me to develop form in the interface  so they can enter information about projects as(project code,project title, country,sector,year) to the database with out dealing with the database in the  backend .. so how can i develop it because i am still new to the vs.

I was requested to develop a GridView like screen to allow easy DataEntry without the need to Click Save/Submit on each row of the GridView.
In other words, the user wants to edit the GridView Cells in a Web Screen as if he is editing Cells in MS Excel. The Data should be saved as soon as he will exit the cell by pressing the down arrow.
It think the only way to do that is to use Ajax technology, right ?
Maybe jQuery or ExtJS ?

I currently have a number of clients who use a cms I have developed. My clients are mainly small web design companies or marketing agencies. I developed a cms, which i customise for each client, with them passing the work off as their own. This cms is built in PHP. have always been keen to move to the .net framework, but over the years have only really completed a couple of projects. Recently I have read a lot about aps.net mvc, and I have started to pick it up. I am finding the learning curve prertty steep, but I am impressed with itI am starting to look forward to the development of a new version of my cms, and I am considering building it using .net mvc, the only issue is, that i will have persuade my existing clients that they should support my decision to do this, and I currently cant really think of any benefits for my clients.
