Is there a way to handle Dynamic Forms using ViewModel?

Posted By:      Posted Date: September 16, 2010    Points: 0   Category :ASP.Net
Hi,I need to create a dynamic form using the already existing DB entries, from 3 different tables. I am trying to do this by inheriting ViewModel class, which is comprised of all the model instances (or List of instances of unknown count) within it. When I inherit the ViewModel in the View Template, the dynamic form gets generated without any issues, and looks fine. The dynamic form is generated based on iterating over the calls for each required model instance in the ViewModel passed to the View.Each call uses a partial view of the instance to generate the form, and hence multiple iterations create multiple instances of the form. <% foreach (Option item in Model.Options) { %> <%: Html.EditorFor( model => item )%> <% } %> However, when I try to submit the form, the postback does not include the ViewModel object, but rather only the first model instance used in the form.Any suggestions or help would be great!!

Custom SharePoint forms with some dynamic behaviour


Hello all,

I have this challenge: I need to create custom SharePoint forms with some dynamic behaviour, without programming(no Javascript, C#, ...)  Background: this form would be used to report expenses and the number of invoices is variable.

We're limiting the options for the solution, because we currently lack the programming skills to develop and maintain the code.  So we wanted to test the ability of SPD to solve our particular business situation.  InfoPath is being considered, but is not yet available to us.

I had thought about using a dropdown control (ASP or SharePoint) to select from a list the number of invoices to report.  Then I'd take the selected number as a parameter to conditionally display the necessary fields (date1, amount1, description1, date2, amount2, description2, etc.).

I also need to save the selected number of invoices as part of the expense report, because I can use it in a SPD workflow as part of my process control.

What I have found is the following:

* If I use an ASP dropdown, I can convert the selected number into a parameter and have a "dynamic form" but then I don't have a way to save the number selected in one of the fields (columns) of the expense report.

* If I use a SharePoint dropdown, I can save the number selected in the dropdown, be

Dialogs and ViewModel - Using Tasks as a Pattern

The ViewModel/MVVM pattern continues to gain popularity, with a blog post showing up every so often, and with tweets and retweets popping up even more often :-). At the same time, there are some interesting topics beyond the core pattern that continue to fuel experimentation. A big one amongst those is how should applications use dialogs when using the view model pattern.

The crux of the problem is the desire to keep the view model independent of UI concerns, and ensure it can be tested in a standalone manner, but that often comes to odds when you want the view model to launch a dialog, and/or do some work after the dialog is closed.

Adding Dynamic Rows in ASP.NET GridView Control with TextBoxes and with Delete functionality

In my previous examples, I have demonstrated on how to add dynamic rows in GridView control with TextBoxes and how to save the values into the database. Now, seems that most of the developers are asking if how to add a delete functionality with it. So in this example, I'm going to show on how to delete a certain row in the dynamic GridView with TextBoxes.

Dynamic Data Templates in GridView ASP.NET 3.5

At a high level, Dynamic Data Templates can be seen as a system to very quickly build up a User Interface linked with the relevant data model, immediately enabling you to perform CRUD operations (Create, Read, Update, Delete) on the database using the specified data source. They provide a powerful method for building up these kinds of applications, and I'm going to focus on an overview of what Dynamic Data Templates actually are, and a few ways of customizing them to suit industry needs.

A Generic Dialog ViewModel

I worked on a wpf viewmodel for dialogs, because it seemed strange to me that you needed for instance windows forms dialogs to open or save files in wpf. So I set about creating my own wpf dialogs. After creating the dialog viewmodels there still remained a small issue with the library and also I didn't have much time to write an article about it. I however published the library containing the viewmodels for dialogs with another article on my blog

Routing for Web Forms in ASP.NET 4.0

posted a prototype demonstrating how one could use Routing within Web Forms. This is something you can do today with ASP.NET 3.5 SP1, because of the work we did to separate Routing from ASP.NET MVC. I would have liked to include Web Form Routing as part of the Routing feature when we were working on SP1, but we didn't have the time to do so in a robust manner before SP1 was locked down.

Dynamic Systems Development Model (DSDM) Methodology

The Dynamic Systems Development Model was developed in the U.K. in the mid-1990s. It is the evolution of rapid application development (RAD) practices. DSDM boasts the best-supported training and documentation of any of the agile software development techniques, at least in Europe. DSDM favors the philosophy that nothing is built perfectly the first time and looks to software development as an exploratory endeavor.
