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?

Hi,

I'm using PivotGrid and it's a amazing control.
Now, I need to localize PivotGrid and PivotFieldList to "pt-BR".
I've done this with GridView with LocalizationManager, but I didn't find a table with key-description pair in PivotGrid documentation as I found in GridView documentation.

Another point is that I don't know how to display a user friendly name to my columns.
In both, PivotGrid and PivotFieldList, they show only the original property name of my object.

Regards, JP.

Is there an easy way to control where the dialog window is displayed? Our client would like the window to display directly above the selected appointment much like a tool tip. Can this be done without doing a lot of casting of the mouse location?

Thanks!

Hi,

I have implemented a method that handles my ScheduleView's DialogClosing event. In this method I am determining if the appointment about to be created overlaps with any other appointment and I am prompting the user to confirm their action if an overlap was detected since merging will take place.

In the answer to this thread, Konstantina mentions that: "There in the event's arguments, the DialogResult shows whether the ok or cancel button has been clicked"; however, the CancelRoutedEventArgs does not have a DialogResult property and I cannot figure out how to retrieve the this information.

So, my question is: how to you retrieve the DialogResult within the ScheduleView's DialogClosing event?

I am looking forward to your advise.

Thank you,
