Questions on UI for WPF Forum

I'd like to clarify the discussion towards the bottom of this page, http://www.telerik.com/help/silverlight/radchartview-series-databinding.html, specifically:

"If we needed to track the selling of our products in real-time, we can simply put the product types in an observable collection and whenever we update a product's sold quantity, the chart will be updated."

and

"The only requirement left for the code above to work is that our Product class needs to implement INotifyPropertyChanged and raise the PropertyChanged event when its QuantitySold property changes"

If we are using GenericDataPointBinding, how does the chart know that it's the QuantitySold property that it is interested in (because it binds to that property via a lambda)? (This become relevant, if for example, the Product class has other properties, not displayed in the chart, that cause PropertyChanged events). Does the chart listen for a PropertyChange on any property and then attempt to find the new value of the data point?

DataTemplateSelector, containing class of property?

When I use a DataTemplateSelector, the type passed into SelectTemplate via the item parameter is PropertyDefinition. I can get things like the name of the property and the type of the property, but how about the type that contains the property? If I have five classes with a string property called "Reference" and I need a data template for each of those, I need the name of the class that contains that property to select the proper template. How do I obtain that information?

[Solved] FilterDescriptors problem

Hi,

in my application I have a RadGridview. I have a RadButton to launch a call to my backend to get data. When the user want to apply filters on a column, he click on the column header icon, the color of the icon change and he can select values in the dialog (see: filters ok.png).

When the user click on my RadButton, I call the RadGridView.FilterDescriptors.Clear() method, the filter icon in the column header change but the values in he filter dialog remain checked (see: filters not ok.png). By the amount of data in my grid, I can see that the filters was removed but like I said, If I go back in the filters dialog, the values remain checked.

Thank's

[Solved] DataTemplate in new RadPaneGroup

Hello, I am using the RadDocking to manage a collection of panes. I have a DataTemple with a EditableContentControl to allow modification of header text. This works quite well with the exception of when a pane is moved to a new group. When a RadPane is removed from the initial RadPaneGroup and placed in a new location, and I add a new pane, all RadPanes in the new RadPaneGroup do not utilize the DataTemplate defined in the initial. Is there some resolution to this?
You can see from the XAML below that I am binding the ItemSource for the RadPaneGroup to a collection using an extension. The newly greated RadPaneGroup does correctly bind to the collection of panes so I had assumed that the DataTemplate too would be applied.

Thanks

Paul

Aggregates, display all groups

Hello,

I would like to know if there is any way to show empty groups in the gridview when aggregates functions are used ?

For exemple :
I have these datas :
groupA sample
groupA sample2
groupB sample3

Actually, I see this :
groupA Count : 2
groupB Count : 1

And now I want to see this :
groupA Count : 2
groupB Count : 1
groupC Count : 0

It is possible to have this ?
Can we defined groups for the aggregates and so see also empty groups ?

Thanks !

How is RadToolTip used?

Nothing in documentation or here in the forums on how RadToolTip is used...

Should be as simple as this:

xmlns:t="http://schemas.telerik.com/2008/xaml/presentation"

<t:RadToolTip>
   <TextBlock>
       Some text.
   </TextBlock>
</t:RadToolTip>

or this:

<t:RadToolTip>
   <t:RadToolTip.Content>
       <TextBlock>
           Some text.
       </TextBlock>
   </t:RadToolTip.Content>
</t:RadToolTip>

But all that is displayed in the UI is "System.Windows.Controls.Textbox".
