re: Introduction to the Infragistics Undo / Redo Framework for XAML applications

Louis — Thu, 04 Apr 2013 23:01:03 GMT

OK. I have a very limited demo of the undo framework working on a XamPivotGrid. Lots of limitations but this is just a proof of concept. It seems promising but lots of issues to solve.

1) This will probably only work with a flat data source as mentioned above.

2) When editing a cell in XamPivotGrid, this may trigger changes to more than one item in the data source. In fact, it almost always does! Therefore, when making one change in the grid, you need to atomically undo/redo several operations on the data. I don't see any way to make these multiple operations on the data appear to be a single operation to the UndoManager.

3) When an undo takes place, I need a notification from the UndoManager that undo happened so I can tell the XamPivotGrid to refresh the view. For other controls, as long as the backing view model supports notification, the view will update itself. However, with XamPivotGrid, it appears that I need to call XamPivotGrid.DataSource.RefreshView() to get the changes to show in the view. So I need the undo manager to tell me when the data update completed.

I am trying to implement these three items myself for now. We'll see how it goes.

Interesting response Damyan. I recieved a separate email from Infragisitics support saying that XamPivotGrid wasn't supported for Undo but I had the same thought as you. The undo framework, works on the data not the UI control so I thought it SHOULD work. I am working through a sample right now and I can bind my XamPivotGrid just fine to the ObservableCollectionExtendedWithUndo enumeration but I am not getting Undo operations. Perhaps it is because my underlying data type isn't notifying the UndoManager properly when the data changes. I am just editing data in the cells, not removing/adding items in the collection.

Good question, Louis!

I guess I didn't quite make it clear enough - the framework works on data level (not control level) by providings an extended version of the observable collection(ObservableCollectionExtended) and optionally assigning an Undo manager to the model.You can check out this this help topic with detailed guide on doing just that.

Regarding the XamPivotGrid most surely the undo manager will work just fine when using a flat data source and anything else you can translate to such, but I'm not too sure about the XmlaDataSource - I'll see what I can learn about and and give you an update :)

Can this framework be used on xamPivotGrid as well as xamGrid? I would like to use it in the Pivot grid but seems like the samples indicate xamGrid as opposed to xamPivotGrid.

Thanks,

Louis

re: Touch Gesture Support for XAML NetAdvantage controls

[Infragistics] Damyan Petev — Thu, 13 Dec 2012 16:00:53 GMT

Hello Florian,

From what I remember Windows 7 is the first one to ship with touch support, so in regards to minimum requirements it might just be it. I guess other OS might be translating touch to mouse events at least. For your specific case - definitely, Win7 + touchscreen works just fine :)

Still a good catch I will do some digging to see if anything special is done under the hood to support older OS and suggest that it should be reflected in the documentation.

Thanks,

Damyan

Damyan,

impressive possibilities. What exactly are the minimum requirements for the IG controls to support this? Specifically, is this also possible with Win7 and a touchscreen?

Regards Florian

re: Using NetAdvantage JQuery Upload Control in ASP.NET MVC

[Infragistics] Damyan Petev — Mon, 05 Nov 2012 17:33:56 GMT

Hey jouin,

I'm not quite sure what your problem can be. Code behind is not entirely relevant to MVC and if you are using VB that list initialization is C# :) So, I've made a sample in VB setting the allowed types to an upload model in the controller and it all works great:

media.infragistics.com/community/jquery/codesamples/dpetev/Uploader-in-VB/VB_Upload.zip

The VB.NET equivalent of the inline list initialization would be something like this:

Dim upload As New UploadModel
upload.AllowedExtensions = New List(Of String) From {"jpg", "bmp", "png"}

OR if you are using chaining syntax in the view:

@Html.Infragistics().Upload().AllowedExtensions(New List(Of String) From {"jpg", "bmp", "png"})

jouin — Mon, 05 Nov 2012 00:46:30 GMT

I'm trying to set the allowedextentions in the codebehind in VB.net but the line:

.AllowedExtensions(new List<string> { "jpg", "bmp", "png" })

Dose not work, any help would be great!!!!

re: Live data - starring the jQuery Grid, WebSockets and KnockoutJS

James Schreuder — Mon, 22 Oct 2012 01:09:36 GMT

Thanks for the samples Damyan.

I have created a complete Visual Studio 2010 sample using your tutorial (see www.schreuder.com.au/.../InfragisticsWebSockets.zip). The sample combines:

* Infragistics jQuery igGrid

* Knockout.js

* SuperWebSockets

The "SuperWebSocketServer" project contains a simple GUI based server. You can connect to this server using the example index.html page in the InfragisticsKnockoutSuperWebSocketsGrid project. The web page shows an igGrid that receives live stock market price updates after you start the live data feed on the GUI server. You can also broadcast a message out to each connected browser.

I hope someone else finds this useful.

Cheers

James
