Loosing Selection in CollectionViewSource

I have an applicaion with 1 to many tabs that are in viewModel to view fashion with the ViewModels contained in a CollectionViewSource. This works great for other controls that I can start an edit, switch tabs an retrun with edits in place. The gridView is not maintaining selection, sorting or filtering (I believe because it is reinitializing) when the tab it is contained on looses and regains focus.
The grid looses filters, sorting and selection.

[Solved] FrozenColumnCount Problems.

Hi
I am having some problems with the TreeListView when using the FrozenColumnCount property.
The column header does not align with the cells, ie. the cells take up more space than the header.
Looks like this ascii :)

| Header |
| Cell |

Any idea what is causing this. I'm using the Official Q1 2011 Release.

Best regards
Kristján.

[Solved] Drag and Drop and SchedulerDialog

Hi there,

I have the following problem with ScheduleView and Drag and Drop. As recommended, I implemented a custom DragDropBehavior class that inherits from DefaultDragDropBehavior. In here everything works fine. After the "public override void Drop(DragDropState state)" method was called, the new created appointment is passed to the AppointmentCreating event of the ScheduleView. My Problem is that I want to show the scheduler dialog as it would happen if AppointmentCreating event was produced by a doubleclick. Instead of showing the dialog the AppointmentSaving event handler is called immediatly. How can I achieve it that the dialog will be shown? Since I have different IResourceType objects in my scheduler I need the dialog to give the user the possibility to set them correctly.

thanks in advance,

michael

Cell background color

Hi,

I have a RadGridView with GridViewDataColumn. I'm the column is using a binding with IsReadOnlyBinding (and it's working well the cell is read only as expected). I would like the cell to take on a special color a when it's ReadOnly based on a binding in XAML.

I tried to do a trigger on GridViewCell.IsReadOnly but it's not working since IsReadOnlyBinding doesn't seem to affect IsReadOnly (that's rather strange).

Am I missing something or am I doing something wrong ?

row expand/collapse

Our requirements are, On expanding or collapsing any node we should retain the summary1 & summary2 rows irrespective from the level (means, we have to retain the summary1 & summary2 rows for all levels).

column1 column2
parent summary1
summary2
-child
summary1
summary2
a1
a2
-grandchild1
summary1
summary2
a3

Is this possible on treelistview control?

Please consider this as priority.

Thanks,

Slots layering

Hello Telerik,

The special slots are really nice to visually represent the resource's availability.
Our resources have default schedules with free (green) and occupied (red) time (with some recurrence).
However on some occasions we need to display an exception on these default schedules (some holiday, maintenance of equipment, sick leave of some person, a general strike, whatever :-) )

In these occasions, I add a new special slot (and a style selector, and a Style - a reddish hatch or maze - in xaml) and add them to the special slots list. The styles I'm using are semi transparent and I can see all of them on the calendar as expected. However I was unable to control the Z-index, so sometimes I see the maze (exception slot) below and sometimes above the default slots. (I'd like them to stick on top)

I tried to control the layering the way I control the order of shown resources (by sorting them in the ResourceType), but that din't work.
I also tried to control the layering using the Z-index.

UPDATE: sorting the special slots does work. I sort them (in the viewmodel) based on the derived Slot classes. The last in the list is the one on top. Problem solved. (However it would be nice if the Panel.ZIndex would work on the HighlightItemStyle)

Greetz,
Nico

[Solved] Custom row layout not binding!

Hey I followed your example for customizing the row layout.
The custom row now shows but it's not showing the binding data and if I remove the RowStyle="{StaticResource rowStyle}" parameter and display the GridViewDataColumns with the bindings, the data then displays.

Can you help?
