Hello,

I do maintenance in a Silvelight 4 web application that use dataform.
I mainly use dataform AutoGenerateFields="True" and its works well.
But with comboBox I need to define wether I want a default value or not. The combobox seem to be " mandatory", cause when I select the empty value et validate the form the validation/exception msg "Input is not in the correct format is diplayed" in red.

Is there a way to allow null value and avoid "Input is not in the correct format" message?

Thanks in advance

JEROME

Good job, I read another article and created a Data Form from it, but this one allowed me to understand how it actually works,,, Thanks!

If there a way to place the field label in top for an individual field?

Can the DescriptionViewer be on at all times?

form.show() in Silverlight

The article has been updated to the latest version of Silverlight and Visual Studio.

fails to validate and save

Big SNAG!!

if you say dataform.CurrentItem = obj; and obj is of type private class, the form acts weird! It shows the fields but doesn't save or show validation errors!

When I try to use the System.Windows.Controls.Data.DataFormToolkit.dll rather than the System.Windows.Controls.Data.DataForm.dll I no longer have access to the .Fields property of the DataForm, which is used for customization of the DataForm. Any ideas?

I cannot find System.Windows.Controls.Data.DataForm.dll anywhere. I have downloaded SL 3 as well as toolkit and ran a search on my c drive and it found no file with that name.

Why don't I see Windows.system.Controls.Data.DataForm Dll when I try to add a reference to it? All of the other .Data Dlls are there. They are all under C:\Program Files\Microsoft SDKs\Silverlight\v3.0\Libraries\Client.

Nice introduction, thumbs up!

Worth mentioning, this code needs some adjustements in order to make it work with the latest release of the Silverlight Tookit. Some attributes names have changed - see here: http://silverlight.net/forums/p/109581/258546.aspx. Also, a nice enhancement of the new out-of-the-box DataForm is that it now automatically places a combobox to edit the values taken from an Enum (Genere), instead of a textbox, like it was the case with the old version.

Thanks for the post, very useful.

Now I am trying to include lookup capabilities for reference data in my model. So with your example of the movie you also have a genre, in this example it's probably an enum, but potentially it is another domain entity with its own form to manage the genres. Does the dataform control include the ability to have this reference data included as either a dropdown list or as a lookup control in order to select a value from the reference entity? I understand that I could customize the template to include this, but it would be time saving if this were built into the control. ASP Dynamic Data has this feature.

Any comment will be useful

Hi,

Can we add dynamically user control instead of statically defining it in to Data Template in XAML code.

Thanks,

Abhinay Agrawal.

I've found out that if you don't have a default constructor for the class record bounded to the dataform ItemSource the "+" icon add button will never be enabled.

RE: Creating Rich Data Forms in Silverlight 3 - Introduction

Mark — Tue, 28 Jul 2009 08:46:54 GMT

I can't seem to get the add item "+" button to be enabled. The "+" icon is visible but it's always grayed out. My ItemsSource is set to an ObservableCollection and the delete icon "-" isn't gray and works. I'm not using the Beta. Anyone else having this problem?

@Mark: Sure! You can use whatever control in a field

What about a passwordBox? Can you do this with DataForms??

@Satish: Look at the part Customizing DataForm Fields. You can use DataFormTemplateField field to create your own display & edit fields. For each custom field you define a DataTemplate so you can place your custom controls in it.

@boyanmihailov: Sorry, I could n't trace my requirement in the URL : http://www.silverlightshow.net/items/Creating-Rich-Data-Forms-in-Silverlight-3-Customization.aspx.

Reiterating my requirement: We use custom controls in our aplication. Hence, every string data must be displayed using our own Text control (NOT using Silverlight control). Similarly every date time fields must be bound to our custom datetime control.

Is there a way to achieve this. Kindly help with source code if possible.

@Satish: Yes, you can. You can see my article about customizing DataForm control - http://www.silverlightshow.net/items/Creating-Rich-Data-Forms-in-Silverlight-3-Customization.aspx

Satish — Wed, 15 Jul 2009 14:23:21 GMT

Is there is a way in Dataform to specify the control (Custom control instead of standard textbox control for a string property) of my choice, that would be created dynamically for each of the property?

Hey Jarred: Did you try this:

ObservableCollection> collection = new ObservableCollection>();

dataForm.ItemsSource = collection;

boyanmihailov — Fri, 24 Apr 2009 03:08:46 GMT

@Cris: You can customize everything :) In my next articles I will show you how you can change the entire style of the control and how you can specify your own validation rules and messages.

@Jared: It depends on your necessities. The DataForm control gives you a lot built-in features. You can change everything of its UI. I have not worked with "Observable Dictionary", but here is what I found - http://social.msdn.microsoft.com/forums/en-US/wpf/thread/2ec0c111-0682-49c8-a9d8-ae374328ea2e/

RE: Creating Rich Data Forms in Silverlight 3 - Introduction

Jared Thaler — Fri, 24 Apr 2009 02:55:43 GMT

Also, while Observable Collections are nice, is it possible to make this work with a Dictionary<> Type?

(For that matter, has anyone worked out an "Observable Dictionary" Type?)

RE: Creating Rich Data Forms in Silverlight 3 - Introduction

Jared Thaler — Fri, 24 Apr 2009 00:36:41 GMT

Very Nice.

While, unfortunately, this will be next to useless for my main program (the user interface is vastly more complex than this would appear to natively support.) It should cut dev time on the Admin Backend by at least a quarter.

RE: Creating Rich Data Forms in Silverlight 3 - Introduction

Cris — Thu, 23 Apr 2009 18:34:25 GMT

And how can we customize the labels? or even the error messages? any thought about it?

Thanks for the tutorial! I didn't know this existed in Silverlight 3.
