I have some .xml files that are packages of some classes. I want to show those classes in telerik wpf diagrams control as a class diagram.
What is the best way of displaying class diagrams in WPF from .xml files? It should also populate diagrams automatically, that there is a minimum number of intersections in connections.

Thanks,

Custom footer with aggregate function!

Hi,

I want to have a footer in one of my gridview columns that has two rows: one containing a textbox bound to a field in model view, and the second row displays the sum of items in that column.

---------------------------------

Total: {text box}

<sum>

---------------------------------

I have followed the suggestion from another thread to have a style for the footer to set the binding, and then reference that style on the column.

<Style x:Key="SalesTotalStyle" TargetType="telerik:GridViewFooterCell">

<Setter Property="ContentTemplate">

<Setter.Value>

<DataTemplate>

<Grid>

<Grid.RowDefinitions>

<RowDefinition />

</Grid.RowDefinitions>

<TextBlock Grid.Row="0" Width="75" TextAlignment="Right" FontWeight="Bold" Text="{Binding Path=DataContext.SalesSum,

RelativeSource={RelativeSource AncestorType=telerik:GridView}}" />

<TextBox Grid.Row="1" Text="{Binding Path=DataContext.ExpetedSalesTotal,

RelativeSource={RelativeSource AncestorType=telerik:GridView}}" Width="75" TextAlignment="Right"/>

</Grid>

</DataTemplate>

</Setter.Value>

</Setter>

</Style>

This works great and it does display y the data properly in the textbox. However, how can I add an aggregate function in the style section??
I undetstand aggregate functions will not show if the footer is set. I have also tried to create a sum property (SalesSum) that reruns the sum of underlying data, whoever it doesn’t get refreshed in the grid as the user enters items in the column. Any suggestion?

Cheers

[Solved] ManipulationAdorner offset

Hello,

for some reason, the manipulation adorner is offset relative to the shape after selecting a rotated shape (see attached image).
When selecting a shape with rotation angle = 0 and while rotating it, the adorner stays at the expected position.

What could be the cause for this behavior?

Strange behavior on the rows frozen

I have a spreadsheet control with data and the headers frozen by code.

Then any filter is applied on any column, that works. But when the filter is cleared by
the option “Clear Filter” some rows are frozen in addition to the previous
frozen header. In some cases, after clearing the filter, all the visible rows
are frozen and scroll does not move anything…

Any help?

MouseHover for RadDiagramShape

Hello,
I have some questions,

1- How can I control the MouseHover in RadDiagramShape from code behind not from xaml?

2- How can I keep only one connector for RadDiagramShape?
I tried
MyShape.Connectors.RemoveAt(1);
MyShape.Connectors.RemoveAt(0);
It worked
Is there no easier way or a way to remove them all? or I can keep the middle one(Center Connector)?

Thank you.

[Solved] Expand Nested Properties At Startup

I've searched for this for a while. Is there a way to expand/collapse nested properties via code-behind? It would be nice to have all properties expanded by default in my program.

character display

I need to create a custom text editor, which will be editing device specific files. The files are text files and supposed to contain a subset of the low ASCII characters. Some of the characters should display as strings rather than as their normal display value in the loaded windows character set. I need to display tab characters in their expanded representation as spaces. The files use Form Feeds (x0C) to mark pages. These need to be represented on their own line as a string of dashes. Can this type of character rendering control be accomplished with the RichTextBox control and it's txtformatproviders? If so what would be involved (or is there an example in the SDK's I should look at?
