MainWindow "frozen"

Hi,

we had UI.for.Wpf version 2016.3.1024 before and we updated to 2018.1.122. We started to have problem after update.

Scenario: We have background worker which starts long running operation. When it finishes, we do some actions in WorkerCompleted event handler. We show RadWindow. When its closed, we do some data refresh there and then we programatically change tab in Ribbon to show user final list with results.

Then app seems to be frozen. Better to say, it is shown on screen, but I can click on items behind window. fe if there is desktop behind, I can manipulate items on desktop.

Steps to unfreeze: Click on application incon in task bar. App gets minimized. Then click on that icon again and app gets maximized. App is then working fine again.

Unfortunately, its so rare that we cant debug it or at least create some demo for you. So, we dont know what is suddently causing this. Our observation is that it happens on Win 10.

Question is now, what can we do to prevent this strange behavior? sure, we can downgrade previous version we used. Any other suggestions? Can you help us please?

No Visual State Changes with GridViewGroupPanel

Greetings,

I need to slightly change the GridViewGroupPanel of the WPF GridView to include a close button. After creating a copy of the GridViewGroupPanel Style via Visual Studio, it seems that the visual state changes are no longer firing. I've made no changes to the style after the copy was created, and I can see that the copy contains the visual states for changing the panel text after groups are added, but it doesn't change after dragging a column to the group bar.

Was wondering if perhaps I was missing something? I wouldn't think creating a copy of the control style (no modifications) would disable the visual states..

inherit RadTreeViewItem

hello,

i am new to the telerik controls and i have a question to the radtreeview.

I have two normal classes and a hierarichal template. Everything works fine and the data is shown in tree.

Instead of the normal class i want to use the radtreeviewitem. I try to inherit wich works for the nodes but

not for the childs. Can you please give me a advice how to do this. Here is my code and my problem is

the Children property in the class recursiveObject. Thank you and greetings ....

public static ObservableCollection<RecursiveObject> FillRecursive(List<FlatObject> flatObjects, int parentId)

{

ObservableCollection<RecursiveObject> recursiveObjects = new ObservableCollection<RecursiveObject>();

foreach (var item in flatObjects.Where(x => x.ParentId.Equals(parentId)))

{

recursiveObjects.Add(new RecursiveObject

{

Data = item.Data,

NodeId = item.Id,

Menge = item.Menge,

Selected = false,

ParentKey = item.ParentId,

Children = FillRecursive(flatObjects, item.Id)

});

}

return recursiveObjects;

}

public class FlatObject

{

public int Id { get; set; }

public int ParentId { get; set; }

public string Data { get; set; }

public int Menge { get; set; }

public FlatObject(string name, int id, int parentId, int menge)

{

Data = name;

Id = id;

ParentId = parentId;

Menge = menge;

}

public class RecursiveObject : RadTreeViewItem

{

public bool Selected { get; set; }

public int NodeId { get; set; }

public int ParentKey { get; set; }

public string Data { get; set; }

public int Menge { get; set; }

public ObservableCollection<RecursiveObject> Children { get; set; }

}

Datapager not displaying

Hi,

I have a relatively simple RadGridView with a datapager. On one machine everything works fine. However, when I check out the sources to another machine everything works, but the datapager does not display, and there is no indication of an error. Any ideas how I could track this down?

Thanks ... Ed
