RadScheduleView allow a drop event on given resource on the group header left side (not in a time slot)

Hello there,

We already manage drag and drop operations fine to a RadScheduleView target in an empty slot or on an existing Appointment. However we need to manage a drop event on a given resource on the left-hand side of the Schedule-View (resources displayed vertically here). I mean in this case, we do not drop on a time slot, but on a resource header.

Just to make it clear : if a drop occurs on a given slot, we can already create an appointment for that slot. Now we would like to provide an action "Create Appointment for that resource and find our the time slot automatically based on some business logic". You see?

So far, it seems the DragDropBehavior.CanDrop() method is not involved when we drag over the resource header on the left side of the ScheduleView.

Thanks

Changing window colour

Hi, I'm utilizing telerik's window 8 theme on the windows. But sometimes I would like to display the window as red to indicate it as an error. I would do the follow

Windows8Palette.Palette.AccentColor = Color.FromArgb(0xFF, 0xE0, 0x00, 0x00);

The issue with doing this is that I always have to change it back to the original colour after the window is shown. Any tips on a "better" way to do this.

Windows8Palette.Palette.AccentColor = Color.FromArgb(0xFF, 0xE0, 0x00, 0x00);

RadWindow.Alert(new DialogParameters

{

Content = new TextBlock { Text = message, MinWidth = 200, MaxWidth = 450, TextWrapping = TextWrapping.Wrap },

Header = header,

Theme = new Windows8Theme(),

Owner = Application.Current.MainWindow

});

Windows8Palette.Palette.AccentColor = AppConfiguration.DefaultBlue;

return header;

Custom Grid Header Filter

Hi,

At the moment, one of the columns has no filter. In my model, that column is a collection of strings. For the grid, I append them together separating by a comma.

Person.cs

Name
Collection<strings> Tags

John Doe, new List("Apples", "Oranges")

In my grid, it appears as "John Doe" in the first column and "Apples, Oranges" in the second column.

In my database, I do have a collection of all the tags, I was wondering if I can create a custom filter such that it'll check if it contains the tags I select to filter by.

Hierarchical Grouping and Filtering with TreeView WPF

Hierarchical Grouping and Filtering with TreeView WPF

Hello,

After long searches, I have finally found a way to (somehow) achieve my requirement to display my Resources in some sort of Hierarchical groups, through a TreeView.
This works quite well, as the TreeView can even be seen as a row header in some way.

However, I got some new Requirements.
I need to display my Treeview in another part of my View (or even hide it)
Therefore, I thought, that it might be possible to modify my CustomGroupHeaderContentTemplateSelector to Bind its Content (instead of an empty Content)

<telerik:GroupHeaderTemplateSelector x:Key="CustomGroupHeaderContentTemplateSelector">

<telerik:GroupHeaderTemplateSelector.HorizontalTemplate>

<DataTemplate>

<ContentPresenter Content="{Binding FormattedName}" Height="16" Margin="4"/>

</DataTemplate>

</telerik:GroupHeaderTemplateSelector.HorizontalTemplate>

<telerik:GroupHeaderTemplateSelector.VerticalTemplate>

<DataTemplate>

<ContentPresenter Content="" Height="16" VerticalAlignment="Top" />

</DataTemplate>

</telerik:GroupHeaderTemplateSelector.VerticalTemplate>

</telerik:GroupHeaderTemplateSelector>

to

<telerik:GroupHeaderTemplateSelector x:Key="CustomGroupHeaderContentTemplateSelector">

<telerik:GroupHeaderTemplateSelector.HorizontalTemplate>

<DataTemplate>

<ContentPresenter Content="{Binding FormattedName}" Height="16" Margin="4"/>

</DataTemplate>

</telerik:GroupHeaderTemplateSelector.HorizontalTemplate>

<telerik:GroupHeaderTemplateSelector.VerticalTemplate>

<DataTemplate>

<ContentPresenter Content="{Binding}" Height="16" VerticalAlignment="Top" />

</DataTemplate>

</telerik:GroupHeaderTemplateSelector.VerticalTemplate>

</telerik:GroupHeaderTemplateSelector>

On Start, the application works (and displays its data) as expected
BUT,
I came across a MAJOR PROBLEM that you can reproduce in attached sample
When you collapse both items of the TreeView - then expand one (look at header of each row) - then collapse it - then expand it again, you can see that the header text has changed in a way I cannot re-enact (take a look at attached pictures)

My questions now are:
What causes this kind of behaviour?
Is there a way I can avoid this Problem?
What do you recommend, to achieve my Requirements?

P.S.: - The sample is one of yours (Telerik), with only the slight change/add of a binding
        - Yes I even tried it with the latest telerik release 2017.1.117
       - As it is still not possible to add a .rar file to a post in your forum I hosted the sample project at onedrive: https://1drv.ms/u/s!AqROZw-XiIMygxUHdEcNdVy83H-y

Binding XML to RadPropertyGrid

Is it possible to generate a PropertyGrid on the fly by binding it to an XML string?
If not then what would be a good solution here?
I have a property that return an XML string with attributes and values, I need the attributes to be the property display names and values the property values. Maybe parsing the XML and creating PropertyDefinitions? I'd just like to avoid parsing an XML if PropertyGrid has some way doing it.

Thank you for the help!
