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}"

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?

HI,

i create some custom Shapes on my diagram, with a cutom ContentTabTemplate, Now I want to open a RadWindo for some
Input and give the Data back to the Shape? Is this possible?

Thanks
Manfred

Our WPF application contains multiple RadRichTextBox instances. When right clicking in one of the instances I expected the ContextMenu_Showing event to get fired for only the RadRichTextBox control that I right clicked. This is not the case. 

The method gets fired for each instance of the RadRichTextBox.  As a result, instead of getting one "View Source" context menu item inserted into the context menu, I get one for each RadRichTextBox control.

I am trying to implement the modification of the RadRichTextBox's context menu as indicated at the following link:
http://www.telerik.com/help/wpf/radrichtextbox-features-context-menu.html

I also modified the example as indicated in the following blog to reference the correct ContextMenu:
http://blogs.telerik.com/xamlteam/posts/10-11-17/customizing-radrichtextbox-s-contextmenu-and-selectionminitoolbar.aspx

In the Telerik public constructor I have the following code:

            Telerik.Windows.Controls.RichTextBoxUI.ContextMenu contextMenu =
                (Telerik.Windows.Controls.RichTextBoxUI.ContextMenu)this.radRichTextBox.ContextMenu;
            contextMenu.Showing += this.ContextMenu_Showing;

I also have the following methods:

        private void ContextMenu_Showing(object sender, Telerik.Windows.Controls.RichTextBoxUI.Menus.ContextMenuEventArgs e)
        {
            RadMenuItem makeViewSourceMenuItem = new RadMenuItem()
            {
                Header = "View Source"
            };
            makeViewSourceMenuItem.Click += MakeViewSourceMenuItem_Click;
            ContextMenuGroup customContextMenuGroup = new ContextMenuGroup();
            customContextMenuGroup.Add(makeViewSourceMenuItem);
            e.ContextMenuGroupCollection.Add(customContextMenuGroup);
        }        private void MakeViewSourceMenuItem_Click(object sender, RadRoutedEventArgs e)
        {
            FrmHtmlSource dialog = new FrmHtmlSource(_originalText);
            dialog.ShowDialog();
        }

All the examples I have seen involve just one instance of the RadRichTextBox.  Is there anything special I need to do to support multiple instances or is this a limitation with the RadRichTextBox control.

This code takes the DataContext of the Diagram and Serializes it to XML and saves it to file.  However, I want to keep the shape's properties in my own object as XML.  So, I don't want it to save to file.  I want to the read the value into my own object then Serialize my object using XmlSerialization.  Is there any other option to get diagram to give up its XML?   Can this be done using your Persistance framework?

As always, a code example is appreciated.
