Hi,

I try to build a layout defined in the sample image attached.
The principle is that each module has a fixed position, but the size can be changed by the user, in a min / max range.

Here is my code :

Is this the good way to achieve this?
How can I specify the min and max size (height or width) for the RadPaneGroup ? (the given example has unexpected behaviour, as in the second capture)

Regards

I have a RadSplitButton on my form.  The RadSplitButton's DropDownContent contains a RadContextMenu.  Here's a snippet of the xaml:

In the Window's constructor, after calling InitializeComponent, I create an ObservableCollection and assign it to RejectionReasons.  I then populate that ObservableCollection with ItemChoice objects:

 
But the RadContextMenu's Items collection remains empty, even after I populate the collection.  I use this same ItemChoice class with ComboBoxes and ListBoxes and it works fine.  What am I doing wrong?

Also, in my RadMenuItem.Click handler, how do I get a reference to the ItemChoice that generated the RadMenuItem?  It's not at all clear to me from the properties that are available in that class.

Hi we are having some performance problems with using a few instances of the scheduleView.
How can I send you a demo project which demonstrates the problem?

Hi,

We are on the design stage for a WPF Prism application, and we want to provide an editor functionality similar to MS Word in one of our modules. We have a toolbar region in the top of the page that should load the module containing the RadRichTextBoxRibbonUI, and a content region in the middle of the screen that should load the module containing the RadRichTextbox for editing. So the Rich Textbox and its Ribbon are in 2 separate module for loose coupling. In the WPF demo examples, the commands in Ribbon are bound the RichTextbox in XAML (i.e. DataContext and Commands). Is there any suggestion how can we implement our design? Can we pass a reference of the RichTextbox and do the necessary binding in the code at load time of the ribbon?

Any hints would be appreciated!

Dear all who has a knowlege of Heatmap control.

I want to create a heatmap onto a image file. Is it possible to create a heatmap which is having background image?

Here is the xaml:

Here is the code behind:
The problem is when I click the Test button in the example the series does not refresh. This is a simplified example of what we are trying to do but would like the ItemsSource property of the series to behave like it should and update if the binding changes. Any help on this issue is appreciated.

I have a scenario in which I have a ViewModel of a particular type that can hold a Model that can be one of a set of types.

The ViewModel inherits from DynamicObject to expose elements within the Model as properties for the PropertyGrid. In my DynamicObject implementation I am overriding GetDynamicMemberNames, TryGetMember, and TrySetMember. I am keeping my own dictionary of member names and accessors within my ViewModel.

The underlying Model may have different members so that each instance of the ViewModel should appear to have different properties.

I have a list of instances of the ViewModel and the PropertyGrid is bound to the list's selected item. When I switch items, WPF databinding makes calls to TryGetMember within the newly selected ViewModel. However, when that set of calls are made, they're based on the member names returned by the previous instance.

So let's say I have Model1 with properties A, B, C and Model 2 with properties D, E, F. Instances of either can be held in an instance of my dynamic ViewModel. I add an instance of each to the list. I select the item containing the instance of Model1, the PropertyGrid shows three properties A, B, C just fine. When I select the item containing Model2 however, I get an error within my TryGetMember saying that the key isn't found, I look at the binder.Name and it's reading "A" even though this new instance of ViewModel has a model of type Model2 with only the properties D, E, F.

When I switch between these two items, GetDynamicMemberNames() isn't called more than once. I suspect that somewhere along the way the member names are being cached by the name of the type they're associated with. So in this internal cache someplace it's associating my ViewModel class with properties A, B, C and uses that cache to query all instances of ViewModel.

My questions are:

1) Do you know where this caching is happening? Is this in PropertyGrid, in WPF databinding, or within the DynamicObject base class?

2) Is there any way to override the member name caching?

3) Is there any way to force a call to GetDynamicMemberNames() each time a new instance of my ViewModel is loaded into the PropertyGrid?

Thanks for your help.

I have a RadTreeView inside a ScrollViewer.

When the mouse wheel is scrolled over the RadTreeView the parent ScrollViewer does not scroll.

Is there an easy way to change this behavior that I'm missing (or a hard way for that matter)?

Hi,

I have been given the task of rewriting an old application, and I'd like to use the RadControls for some parts of it. In this application, the user has to be able to place items on a schematic view, like this.

I have a couple of questions though, because I wasn't able to figure out how to do the following things from the RadDiagram Help/Tutorials, as I am quite new to more advanced WPF stuff (have only written relatively simple apps before) and MVVM in general:

1. How can I create diagram objects (for starters, they can just be rectangles) that simply have an Image control with their respective Bitmap set as the source (so I can get objects like in the screenshot by using the bitmaps that I have and avoid having to write their Geometry in WPF), with multiple connectors on each side (like the ISDN block in the lower right corner), and a Dictionary for each instance of an object to store custom properties? I've been through the "How To Create Custom Shape" tutorial, but still don't really know how to tackle this problem.

2. How do I add these objects to the toolbox later on? Do I just create a Gallery (ObservableCollection) with those Shapes and add that to the item ObservableCollection of my ViewModel?

Thanks

private void diagram_ConnectionManipulationStarted(object sender, ManipulationRoutedEventArgs e)
{
    MyShape source = e.Connection.Source as MyShape;
    // source.MyData == null?
}

We're trying to add logic for connection manipulation. Why isn't our custom data set in this event when it is indeed set for our nodes in the graph?
