We are using the PropertyGrid to edit the contents of an object and it works fine. However we need to be notified when the user finishes editing an individual property. The EndEdit event comes pretty close (once we changed EditMode to single) but we can not figure out which property was actually edited.

Obviously one solution is to have the object we are editing implement INotifyPropertyChanged and handle the property changed event. Unfortunately we don't have access to this object and the property access methods are not virtual so we can't easily extend it.

Is there a way to tell which property was edited in the EndEdit event?

Thanks

I want to change the order of RadPanes in a RadPaneGroup. Obviously others already had the same problem:

http://www.telerik.com/forums/how-to-change-tab-order-in-radpanegroup

In it above post. There is a Link to your PITS given, that does not work. So how is the status, now that the issue occurred four years ago?


(BTW: PITS looks shitty when you visit it wit an Opera Browser)

I'm using the PdfFormatProvider to export RadDocuments to disk. Adobe Reader prompts me to save changes when these documents are closed. The saved document is slightly smaller than the original.

Is this a known issue?

I'm using RadDiagram for making a designer in our system.
I have three parts in my screen, (RadDiagram, RadDiagramToolBox and ToolBar).

What I have to display in my RadDiagramToolBox are icons (images for my custom shapes) For a reason, my custom shapes can not inherit from RadDiagramShape, That's Why the RadDiagram didn't accept my custom shapes and I made MyDesigner which is inhering from RadDiagram, and override the this.Drop += MyDesigner_Drop;

To do this I used this hierarchy http://www.telerik.com/forums/raddiagramtoolbox-xaml-example#IUr1zXo3zUq-9NytMbeamw '
as the following:
        <telerik:RadDiagramToolbox Grid.Column="0" Grid.RowSpan="3"
                                   Header="{Binding SelectedItem.Header, RelativeSource={RelativeSource Self}}"
                                   Visibility="{Binding IsChecked, ElementName=toolboxButton, Converter={StaticResource BooleanToVisibilityConverter}}">
            <telerik:RadDiagramToolboxGroup Header=" Charts ">
        
                <telerik:RadDiagramToolboxItem Name="TimeChartIcon" Background="Transparent">
                    <telerik:RadDiagramShape Name="TimeChartIcon1" Background="Transparent" BorderBrush="Transparent">
                        <Image Source="/Fathom.TestDiagram;component/Images/TimeChartIcon.png"                    
                               Stretch="UniformToFill"
                               Name="TimeChartIcon2"/>
                    </telerik:RadDiagramShape>
                </telerik:RadDiagramToolboxItem>

      <telerik:RadDiagramToolboxItem Background="Transparent">
                <telerik:RadDiagramShape Name="ValueChartIcon" Background="Transparent" BorderBrush="Transparent">
                        <Image Source="/Fathom.TestDiagram;component/Images/ValueChartIcon.png"                    
                               Stretch="Fill"/>
                    </telerik:RadDiagramShape>
                </telerik:RadDiagramToolboxItem>
   </telerik:RadDiagramToolboxGroup>
            
            <telerik:RadDiagramToolboxGroup Header=" Others "/>
        </telerik:RadDiagramToolbox>

and in MyDesigner_Drag I used this http://www.telerik.com/forums/raddiagramtoolbox-drag-drop#trdWTLlUNEKga8H6yFFsqQ
and I added these lines of code after Admin Tina's codes:
              


What I got is, I can drag the RadDiagramShape  which contains an image  from RadDiagrmToolBox and dropped it as a RadDiagramShape contains the same image inside a RadDiagramShape. (How I could have the image in the new dropped instance?)
But What I want is, I want to check inside the MyDesigner_Drag event any info leads me to know the custom shape that the user has dragged and dropped to create an instance from it. Like (Name or Content->Image source)
I could see that item.Content is an image but I couldn't access to Name or Image Source and I couldn't see the name or source of the image that I hard-coded in Xaml code in debug mode!!

I really need your help.
Thank You.

Hello

I want to find  is there any way to access to tesianChartGrid.grid.xLines property information runtime ?

regards

Hi,


I am incrementing my candlestick count during a live feed test. The ChartView is bounded to an ObservableCollection<Candlestick> which is constantly being  refreshed when an updated or brand new candlestick each period.

The first image (25_candlesticks) is a snapshot of the Chart View  for the first 25 candlesticks displayed.

The next image (100_candlesticks) shows the Chart View after 100 candlesticks are displayed.

As you can see, the chart does not auto right scroll to show a preselected number of candlesticks in the current view, but instead, crams all the candlesticks into the same viewing area.

I do not want this. What is necessary is that I have this instead:

1) To have my very first candlestick appear on the left of the screen

2) as more candlesticks are added, the screen remains un-scrolled until about 3 quarters down the view screen.

3) at about 3/4 from the edge of the view screen, the chart auto-scrolls as new candlesticks are added, while maintaining the current X and Y axis scaling that I initially chose.

Could you please instruct me on how this can be done?

I would very much appreciate a WPF C# sample on this as a reference.

Thanks for any help.

Hi,
    I found it was hard to drag scroll bar up/down when grouping data.  I tried to set CanContentScroll = "True" to fix performance issue. but it doesn't work. Could you give us some advice how to fix this issue. My demo has 50 columns and 10000 record. group ID by default pls see my screenshot
 

How to hide the design tab in Visual Studio and show only the XAML tab when editing a window containing a RichTextBox control or RadToolBar?

How to disable the interactivity of the editor so that normal keyboard navigation in the XAML source code does not move controls on the WPF window?

This slows down the editing considerably and introduces many small unwanted changes in the WPF window controls layout.

Hi!

Is there a possibility to find out the actual scroll position of the GridView? The matter is that I rebind the datasource und therefore the Grid looses the actual scroll position and jumps to the first item.

I experienced a bit with ScrollViewer and ScrollContentPresenter but couldnt find a solution!

Greetings
Philip
