How to bind DataContext to drag visual with dynamic templates

[Maurice]

When creating the drag visual in codebeind, I am not seeing the data being bound to theTileViewItem, although the styles and templates are being applied, how can I get the data to bind?

01.private void OnDragInitialize(object sender, DragInitializeEventArgs args)

02.    {

03.      var data = ((RadRadioButton)args.OriginalSource).DataContext as ITile;

04. 

05.      var payload = DragDropPayloadManager.GeneratePayload(null);

06.      payload.SetData("DragData", data);

07. 

08.      args.Data = payload;

09.      args.AllowedEffects = DragDropEffects.All;

10.      args.DragVisual = new RadTileViewItem

11.      {

12.        DataContext = data,

13.        ContentTemplate = Application.Current.FindResource("DashboardTileView_ContentTemplate") as DataTemplate,

14.        HeaderTemplate = Application.Current.FindResource("DashboardTileView_ItemTemplate") as DataTemplate,

15.        Style = Application.Current.FindResource("DashboardTileView_ItemStyle") as Style

16.      };

17.    }

 

Thank you,

Hello Maurice,

Rather than set the DataContext of the RadTileViewItem to the data object could you please try setting the Content property instead similarly to how this has been done in the following article and let me know if this works for you?

If that is not the case, would it be possible for you to provide more details on your exact setup, or ideally open a new support ticket and send over a sample project so that I can better assist you with this?

I'm looking forward to your reply.

Hi Dilyan,

I did try that first after using that article as a reference (before my original post) with the opposite effect, i.e. data was showing but the template/s was not being applied. I have tried to re-apply the logic and have come up against some other issues. I will re-try once I get back to that area and let you know the outcome.

 

Thank you,
Maurice

Apologies for the delay, I have re-tried the approach (which I am sure I tried previously) and it has worked successfully this time.

Thanks again,
Maurice
