ClientUI MVVM Data Application template (reusable code, Grouping, Copy/Paste)

Hello,

If you don't want to apply grouping, you can discard all grouping settings. You can also see our UXGridView sample or video in our support site.
Currently, UXGridView have not provided style for specific context menu. It can be done, but too much efforts. The good news, your scenario is still a simple case. So, there would be too much effort to discard option.
To discard "copy rows", you would need to use Microsoft Expression blend. Open xaml project in blend.
Right click UXGridView and choose Edit Template>>Edit Copy. After that, expand tree level until you found ContextMenu>>Edit Template>>Edit Copy. Next, in xaml code, find CopyRow command in UXGridViewContextMenu and remove this tag.

HAndy

Hi Handy

Thanks for reply!

1. Yes, I have seen that.

2. I want no grouping by default. How can I do this in xaml?

3. Can I customize the context menu, eg. without "copy rows"?

Best regards

Michael

Hello Michael,

Allow me to help you answer the question one by one.

1. Silverlight class library
Today I've worked with ClientUI MVVM Data Application template. The structure of the generic base classes is great! The only downer is that partly text messages (e.g. MessagePresenter) are hard coded!

Unfortunately it is not possible (I did not manage) to move the dictionaries ModelServices.Infrastructure andViewModels.Infrastructure in a Silverlight class library. In the Silverlight Class Library, I can not reference the assemblyIntersoft.Client.Data.ComponentModel. Is there another way to increase the reusability?

Is probably a mistake in MessagePresenter.cs:
public void AskYesOrNo(string question, Action yesAction, Action noAction) { MessageBoxServiceProvider.Show( "Are you sure you want to delete the selected contact?", "Confirmation", MessageBoxButton.YesNo, MessageBoxImage.Question, dialogResult => { if (dialogResult == DialogResult.Yes) { if (yesAction != null) yesAction(); } else { if (noAction != null) noAction(); } }); }

better is:

MessageBoxServiceProvider.Show(question,"Confirmation", MessageBoxButton.YesNo,MessageBoxImage.Question,

Thank you for the feedback. Of course, you can use that way. If you check our MessageBoxServiceProvider classes, we provided show() methods with several parameters option that you can choose.

The products page is grouped by CategoryID. If I delete the following code ...
<Intersoft:UXGridView.GroupDescriptors>
<Intersoft:UXGridViewGroupDescriptor PropertyName="CategoryID"/>
</Intersoft:UXGridView.GroupDescriptors>
... then I get the error message: The method 'OrderBy' must be called before the method 'Skip'. So I inserted the following code...
<Intersoft:UXGridView.SortDescriptions>
<ComponentModel:SortDescription PropertyName="RegionID" Direction="Ascending"/>
</Intersoft:UXGridView.SortDescriptions>
...I still get the same error message. Order by is still missing in URL:
http://localhost:20316/ClientBin/ClientUIDataAppWithPic-Web-NorthwindDomainService.svc/binary/GetRegions?$skip=0&$take=20&$includeTotalCount=True
It works, if I add the SortDescriptor in constructor. If this is the only way?
public RegionsViewModel() :
base()
{
this.QueryDescriptor.SortDescriptors.Add(new SortDescriptor() { PropertyName = "RegionID", Direction = ListSortDirection.Descending });
}

}

If I am not mistaken, grouping behavior should do grouping with sorting ascending as default. So, basically, it needs to run along with sorting. That's why you got error if you did not specify any sort descriptor in grouping.

3. Copy/Paste
Using the context menu, I can copy rows in UXGridView. How can I paste the copied row again?

We do have this property in our UXGridView. However, we do not provide paste option in context menu. UXGridView area is not designed to be pasted. The format can be different. For now, it can only be pasted into textbox.

Handy
