I have several cases where I have a property that I want to declare readonly, but also give some explanation of how it is calculated/set using the [Display(Description="")] attribute. I would like to do this in the metadata, if possible, rather than override in the dataform itself. Here's an example: [Display(Description = "Total n...

Hi, I'm using SL4 and RIA services. I have a simple table with 3 fields (Name, UpDatedByUserId, UpDatedOn). In my metadata I use Data Annotation on the 2 latter fields so that they do not display. My DataGrid and the related DataForm show each record correctly and, as required, the DataForm only shows the Name field but of course I want...
Hi, I have a simple scenario where I'm displaying some products in the datagrid control and the details of a particular product is shown in DataForm.

I need to design an order form where one row represents and order line and the customer can add item to order. I then want to display a new row under then added row for the customer to add another item. I'm thinking I should use a DataForm, but how do I display all rows at once rather than paging through the line items? ...

Hi I have created a custom control and am trying to use it in a dataform for editing. If I use a standard TextBox, the dataform flags that the data is dirty (it enabled the OK and Cancel button, and displays the *). However, when I use my control, it doesn't. The XAML I'm using is: <toolkit:DataForm CurrentItem="{Binding Path=CurrentEn...
I have a data form that I assign a new Entity class as its current item. The problem is when i tab from one textbox on the dataform to the next the first one reverts back to a blank textbox. If hit save it will save the values you typed buy you cant see them once you tab or click on the next texbox. Below is my xaml and code behind. < ...
Hi %username%, I wonder how you do such thing. Assume, we have MVVM CRUD app which modifies a tree (menu structure, for example). We have a view model with the menu items and two views: the first with a TreeView and the second with a DataForm. Main problems are: DataForm can not handle hierarchical data. Depending on the menu item sel...

I just input a script to grab it from my table and print the data inside the tags of the html email, but as you can see below, it's terribly formed and will not...

I've got a child window that I popup to create events. I'm using the DataForm control and one of the fields is a selection from a listbox of event types. I can see that when the window closes, the event type is set properly on the event. If I pop the window back up and set the event to the one just created, all the fields populate fin...
I'm trying to make a data form in Silverlight 4. Perhaps I'm doing something wrong. The class: public class ExpenseInfoTest { public int MyProperty { get; set; } public int Foo { get; set; } public int Bar { get; set; } } XAML: <local:ExpenseInfoTest x:Key="newExpense"/> <df:DataForm Height="218" ...
I have a data form that is working pretty well. One of the properties of my data object is an ObservableCollection. Right now, in the data form, it only displays the ToString() of the colletion. Not very helpful. I'd like some sort of autocomplete box with valid options, and when the user selects them they will be added to the data obje...
I have a DataForm that does 90% of what I need. I add a few fields of my own. This tutorial provides an example of how to do this, but it looks like I need to override everything to do that. (I'd rather not have that extra bulk.) This question looks like there might be a way by subclassing DataForm, but that seems kinda messy, and I'd l...
