In reference to the ArrangeOverride method the documentation says:

The rectangle occupied by the element. Usually finalSize.
Should you return different size, the Layout system will restart
measuring and rearraning the items. That could lead to infinite
recursion.

I am occasionally seeing this. I have a grid that contains a single hierarchical child grid.

Type A
Type B
related on A.Foo, B.Foo

I don't know how to troubleshoot the root cause, but I can see that ArrangeOverride is being called in an infinite loop.

WTF?

Thanks.

I'm trying to implement a property editor control for an application using the RadPropertyGrid. The user will select from a list of objects and the propertygrid editor needs to change based on the object type. That would be perfectly fine if we were giving access to ALL properties of each object, but we only want to display specific subset of each object to the end user, and that subset will vary based on each object type. For example, an object of type Circle we may want to display the center point coordinates and a radius, while a Rectangle we want to display lower-left coordinates and a width and height. These object classes are defined in a 3rd party library, and each of them have many other properties we don't want to expose.

Ideally it would be great if we could set AutoGeneratePropertyDefinitions to false and define a different set of RadPropertyGrid.PropertyDefinitions for each type, then switch that set of definitions based on the object type. I've used converters to change controls' style properties based on object types before, but since since the PropertyDefinitions isn't a property itself, I can't use that same technique.

Any suggestions?

Thanks!

Hi, 
   how to find the single span between HyperlinkRangeStart and HyperlinkRangeEnd?


Thanks!

Hi,

the Execute Save Method works fine. Now I save the diagram like this: owner.fileManager.SaveToFile();

But, is it possible to save the Diagram fix to a declared path? The best would be, that the user just click
on save and a box apperas after saving the diagram. I don't want to give the user the permission to save
the diagram with an ohter name or on an other direcotry!

Is this possible?

Thanks
Rene

Hi,

I have a Problem with the "CanExecutedSave" Event. If a drop a Shape on my diagram this Event will not fired. I have
to do something else before, for example Close an open the Toolbox with my shapes. Now the to "CanExecuteEvent"
will be fired and after it, I the "ExecuteSave" works fine.

Any Ideas?

Thanks
Best Regards
Rene

Here is my code:

this seems working as expected: the stream contains a diagram image and nothing is shown / added to the visual tree.
The problem is that the diagram is not "completely" drawn, see the attached screenshots (expected vs actual): the additional connection geometries comes from this code (basically a custom connection):


My guess is that Measure / Arrange calls don't triggers everything on the diagram's layout.
Any idea?

Greetings.  
 
   I have searched the forums and not found anything similar to the issue we are experience. 

We have a RadGridView with the ItemSource set to an observable collection of dynamic objects.

The grid works fine for autogenerating the columns for each of the "properties" on the dynamic object.

When we attach a CellEditTemplateSelector to the colums in the AutoGeneratingColumn event, the editing stops working.

What I mean is that when the TrySetMember method is called as part of the CommitEdit, the SetMemberBinder passed in is correct, but the value passed is null.  If we don't use the Edit Template Selector it works fine.

We need the template selector because there are over 200 possible properties on the dynamic object and the user has the ability to add additional ones.  These properties range from simple string fields to values that are selected from a specific list.  The edit templates apply the appropriate control based on the attributes of the property object.

Any help or direction you can provide would be greatly appreciated.

Hi,

i'm looking for a code-snipe which shows me how so create an appointment by c#. It is no problem to create a simple appointment for one day. But if i try to crearte an appointment in serie it doesn't work. The Problem could be the DateTime Property Start and End.

It get this Error:
ArgumentOutOfRangeException.

The added or subtracted value results in an unrepresentable DateTime.
Parameter name: value

NOTE:
Beginn with the Example "ScheduleView and TimeBar". This works fine so far. But if you create an Appointment with a frequency ex.:
Pattern.Frequency = RecurrenceFrequency.Monthly; you will get the error above. 
This part from xaml causes the error: CurrentDate="{Binding ElementName=TimeBar, Path=SelectionStart}"

Dear Telerik Team how can i solve this Problem ???????

Is there a way to customize the horizontal and vertical ruler to display units in inches or mm ?

I have a small test project to check the Drag/Drop feature of RadTreeListView. Markup:

<t:RadTreeListView ItemsSource="{Binding Items}" IsReadOnly="True" IsDragDropEnabled="True" x:Name="tree" AutoGenerateColumns="False">
<t:RadTreeListView.DragCueItemTemplate>
<DataTemplate>
<StackPanel>
<TextBlock Text="{Binding Name}"/>
<StackPanel Orientation="Horizontal">
<TextBlock Text="Children count : "/>
<TextBlock Text="{Binding Children.Count}"/>
</StackPanel>
</StackPanel>
</DataTemplate>
</t:RadTreeListView.DragCueItemTemplate>
<t:RadTreeListView.ChildTableDefinitions>
<t:TreeListViewTableDefinition ItemsSource="{Binding Children}" />
</t:RadTreeListView.ChildTableDefinitions>
<t:RadTreeListView.Columns>
<t:GridViewDataColumn DataMemberBinding="{Binding Name}" Header="Nume"/>
</t:RadTreeListView.Columns>
</t:RadTreeListView>

 

 

 

 

Nothing fancy here... I bind it to a simple hierarchy of Node's and if I drag an item I receive this event in 

 

Am I doing something wrong?
