Hi,

The ClassDiagram example defines the class shape inside <style> definition. I need now dynamically access one TextBlock inside the definition as I need to set the text according to user input. I'm having hard time to do this as following does not work:

This is absolutely driving me crazy, so any help would be much appreciated.

The definition of ClassShape is something like:

This error occurs on RaisePropertyChanged or on this line of code

this.Spreadsheet.Workbook = workbook;

An unhandled exception of type 'System.AggregateException' occurred in mscorlib.dll

Additional information: One or more errors occurred.

here is the code which I use 

input is  stream form ms file dialog

Hello,

This was working in the previous version, but not in R3 2018, with the Office2013 theme.

The column is defined as:

I am finding:
1) Create a PAGE, and VIEW MODEL
2) ON the Page:
Add a Tab Control with TWO Tab Items, on each Tab Item add a RadMap and a ComboBox
3) In the VM Create an Observable Collection of Providers and assign to both Combo Boxes on each Tab Item.
4) In the VM create a property(INotifyPropertyChanged) for each SELECTED Provider from each ComboBox, and BIND the Provider to each Map's Provider Dependency Property. (One List / Two Selected Items /Two Maps)
5) Run the App, switch between the Tabs and switch between the ComboBox's Selected Provider and you get botched providers displaying mixed data.
I have determined that when tabbing from one TabItem to an other, the RadMap gets Unloaded and then Reloaded each time, and several resources gets messed up because you do not call the DISPOSE. But, in fact you cant or else you would not be able to tab back... so there are several additional week references that are not detached and memory will continue to leak leading to poorly managed provider tiles etc...  Either that, or there are static references in both Maps reference... That I am not sure yet, still investigating and leaning on the Provider itself.

Has anyone else seen bad behavior on the RadMap with multiple Providers Binding on several Tabs?

thanks,

The ChartView ToolTip should look like the on in the attached gif.

I figured out that I have to change the TooltipTemplate.

But how can I get the LineSeries X values and Y Values ? In my Source code instead of X and Y I should see in the ToolTip the X value (example: January) and Y Value (example: 2,00). Any ideas ?

Here is my unfinished Source Code: 

Hi,

Looks like, using the VirtualQueryableCollectionView, it is possible to lazy load the data if it is flat, but it is not possible if the data is displayed hierarchically. That is, using VirtualQueryableCollectionView, if GroupBy is done for single\multiple columns, the grouping is done only of the initial few records, obviously, as only few records are loaded initially by the VirtualQueryableCollectionView.

If there are multiple groupings then there is a hierarchy, and one can drill down subgroups step by step. I wanted to know if there is a way with GridView to lazily load the subgroup items.

Any suggestions will be helpful.

thanks
