Hello,

is there any possibility to limit the usable diagram area to the page size (specified using primitives:BackgroundPageGrid.PageSize)?
At the moment, I have only the unimpressive lines from the BackgroundPageGrid - the user can still move the shapes outside of this area (where they won't be visible when the diagram is used as dashboard in action).

RadTreeView jumps to top when resized

Hello @all,

our problem is the RadTreeView always jumping to the top when wrapped like in the xaml below. It took a long time to find out, but in this way I was able to reproduce it. We disabled the ScrollViewer of the RadPanelBar so we can scroll to certain items in the TreeView in the original context.

Expand the RadPanelBarItem, scroll down, select an item there. Move the GridSplitter or just resize the window and the RadTreeView's ScrollViewer jumps back to the top.
Change the RadTreeView and its items to the standard WPF TreeView and items and it stays scrolled where it is. Unfortunately we would be missing certain features of the RadTreeView we would like to use.

<Grid>

<Grid.ColumnDefinitions>

<ColumnDefinition Width="*" />

</Grid.ColumnDefinitions>

<Controls:RadPanelBar ScrollViewer.HorizontalScrollBarVisibility="Disabled"

ScrollViewer.VerticalScrollBarVisibility="Disabled">

<Controls:RadPanelBarItem>

<Controls:RadTreeView Grid.Column="0"

HorizontalAlignment="Stretch"

Animation:AnimationManager.IsAnimationEnabled="False">

<Controls:RadTreeViewItem Header="1">

<Controls:RadTreeViewItem Header="2" />

</Controls:RadTreeViewItem>

</Controls:RadTreeView>

</Controls:RadPanelBarItem>

</Controls:RadPanelBar>

<GridSplitter Grid.Column="0" Width="3" HorizontalAlignment="Right" />

<Button Grid.Column="1">Test</Button>

</Grid>

Any ideas how we could fix this?

Kind regards,
M. Lohmann.

22. </telerik:RadRichTextBoxRibbonUI>

23.</telerik:RadRibbonWindow>

I try get access to element with name "TARGET_BUTTON" with UI Automation API.

01.var app = AutomationElement.RootElement.FindFirst(TreeScope.Children, new PropertyCondition(AutomationElement.NameProperty, "My Application"));

02.var allChildren = TreeWalker.RawViewWalker.GetParent(app).FindAll(TreeScope.Descendants, Condition.TrueCondition);

03.

04.foreach (AutomationElement automationElement in allChildren)

05.{

06. try

07. {

08. if (automationElement.Current.AutomationId == "TARGET_BUTTON")

09. {

10. Console.WriteLine("{0} ({1})", automationElement.Current.ClassName, automationElement.Current.AutomationId);

11. }

12. }

13. catch { }

14.}

But this code don't find the button.
If I set in line 20 IsActive="true" then I can find the button.
I use last version of UI for WPF.

Problem where to attach keydown event

Where should i attach the event to make it work properly?

Now i attach it to a RadPane, but it only works aslong as some objeckt inside the RadPane is focused. If i have the "frame" of the RadPane focused, say after i reposition it, the KeyDown will not fire.

I have tried to attach the event to almost every object above the RadPane in the hierarchy but no luck so far...

Pseudu:

Grid
RadDocking
RadSplitContainer
RadPaneGroup <-- Inside here we dynamically add RadPanes
/RadSplitContainer
/RadDocking
/Grid

Strange issue with horizontal scrolling

Hi there,

I'm having some strange troubles with the RadGridView. I'm populating the grid dynamically in code behind in the Loaded event because the number of columns needed is not known at design time. So far so good and after the data is loaded the grid looks fine. Column and row virtualization are enabled by default, vertical scrolling works and performance is really good. BUT horizontal scrolling does look really strange. The column headers do not move at all and the visible cells just move out to the left side of the grid while something that looks like empty grid rows moves into view by scrolling further to the right. This happens out of the box before I even start fiddling around with the various properties of the RadGridView.

If I turn off column virtualization part of the issue goes away. Headers still don't move and performance of loading and scrolling becomes really bad because there can be hundreds of columns. I tried to change almost every setting on the grid but I can't seem to get rid of the problem...

Regards,
Marcel

How do I render an OSM file in RadMap 2014 Q2?

I'm building a prototype of an application that will utilize offline data from OpenStreetMap.org. So far, I spun up a new WPF project and threw together a quick RadMap using the OSM data provider. The application works but now I want implement a local data source. I downloaded a small dataset from the OSM website. The data is an OSM file and contains XML.

How do I use this file with the RadMap control? I'm new to the RadMap control but have worked with .NET / XML / GIS for years.

Thanks!

How to trigger the auto-ranging of axes

Hello,

I'm using your ChartView in combination with a TreeView and selectable series. I have bound the series visibility to a Checked-Property on my series elements. When I check some series they are drawn in the Chart and the axis scales accordingly. But there is one problem: It does only increase the displayed range and there is no change when I disable the series that caused the range-adaption. So I'm looking for a way to tell the Chart that it must auto-range the whole display area so I have the best view on it. I haven't found such a method and the frameworks UpdateLayout(), Arrange() don't work. Is there any way to accomplish that?

Thanks in advance!

Best regards,
Peter Schmidt
