Hi,

I had installed the free trial of the demos for RadControls and started getting the "Enjoying your RadContolrs for WPF trial?" message when running the installed version of my app but not so when running the app from VS. I have now installed the purchased version of the WPF IU Controls, after uninstalling the free trial, and I’m still getting the message when running the installed version of my app.

(2013.1.220.40) DraggedSokutContainer is obsolete Warning

**** SORRY - the title should have read 'DraggedSplitContainer is obsolete' - TYPO ****

Hi,

I'm getting the following warning in VS2010 when using wpf libraries 2013.1.220.40.

'Telerik.Windows.Controls.Docking.PreviewShowCompassEventArgs.DraggedSplitContainer' is obsolete: 'This should not be used anymore. Use the DraggedElement property instead.

It's relating to the following code I have for conditional pane docking:

private void RadDocking_PreviewShowCompass(object sender, Telerik.Windows.Controls.Docking.PreviewShowCompassEventArgs e)

{

if (e.TargetGroup != null)

{

e.Compass.IsCenterIndicatorVisible = CanDockIn(e.DraggedSplitContainer, e.TargetGroup, DockPosition.Center);

e.Compass.IsLeftIndicatorVisible = CanDockIn(e.DraggedSplitContainer, e.TargetGroup, DockPosition.Left);

e.Compass.IsTopIndicatorVisible = CanDockIn(e.DraggedSplitContainer, e.TargetGroup, DockPosition.Top);

e.Compass.IsRightIndicatorVisible = CanDockIn(e.DraggedSplitContainer, e.TargetGroup, DockPosition.Right);

e.Compass.IsBottomIndicatorVisible = CanDockIn(e.DraggedSplitContainer, e.TargetGroup, DockPosition.Bottom);

}

else

{

e.Compass.IsLeftIndicatorVisible = CanDock(e.DraggedSplitContainer, DockPosition.Left);

e.Compass.IsTopIndicatorVisible = CanDock(e.DraggedSplitContainer, DockPosition.Top);

e.Compass.IsRightIndicatorVisible = CanDock(e.DraggedSplitContainer, DockPosition.Right);

e.Compass.IsBottomIndicatorVisible = CanDock(e.DraggedSplitContainer, DockPosition.Bottom);

}

e.Canceled = !(CompassNeedsToShow(e.Compass));

}

CanDockIn Method:

private bool CanDockIn(ISplitItem dragged, ISplitItem target, DockPosition position)

{

// If there is a pane that cannot be dropped in any of the targeted panes.

return !dragged.EnumeratePanes().Any((RadPane p) => target.EnumeratePanes().Any((RadPane p1) => !CanDockIn(p, p1, position)));

}

Can you offer any suggestions about how I can fix this?

Thank you for your time,

Rob

Change Row Background After Sort

Hi there,

I would like to change the row background of the first 5 rows after the data on the grid has been sorted but I am having a couple of issues.

I hook into the Sorted event and get the rows from the grid and I loop through the first five and set the background. This almost works but it only changes the backgrounds of every second row. I think that the AlternateRowBackground set on the grid is overwriting the value I set.

Another issue I am facing is that there are two ways in which I sort the grid. The above approach only works when the user sorts by clicking on a column. However the Sorted event doesn't seem to fire when I add a SortDescriptor in the code-behind and I'm not sure why.

Is there something obvious that I am missing? Or is there a better approach to achieve what I am looking for?

Thanks,

Steven

Right Choice of the MVVM Framework

Hello,

i saw online the telerik video over Telerik RadControls and using Prism. I found it great and checked any articles in the web. But now i am not sure what is actually the right choice for me?

I would like to develop a bigger business app with wpf and silverlight ui for win7/8 for a logistic company. Perhaps later an ui for tablets and smartphones.

Is the framework Prism still state of the art or does a framework like Caliburn.Micro or MVVM light better fit the needs of an actual windows app?

What is the experience of telerik and yours here in the forum?
The telerik sample demo app in my trial use prism as base right?
So is it still telerik's favorit?

Could you say that it is not wrong to start in 2012 still with prism to develop a business app for the ms plattform?

Thank you in advance.

Many Greetings Sascha

How to create a custom theme for RadScheduleVIew WPF Q1 2013?

Hello,
I want to create a custom theme for ScheduleVIew matching my application. I have tried this tutorial "http://www.telerik.com/help/silverlight/common-styling-apperance-themes-custom-theme-project.html", but it seems like outdated. Telerik.Windows.Controls.Theme class doesn't have a Source property. Do you have any latest links for creating custom theme ?

Radpane and usercontrol

Hi there

I've a radpane that contains a usercontrol with a gridview and some buttons.
The radpanegroup is set that it can't be dragged and the dragdropmode is deferred.

<t:RadPaneGroup AllowDrop="False" t:ProportionalStackPanel.RelativeSize="200,300"

<t:RadPane x:Name="Ticket" Header="Ticket" CanFloat="False" CanUserClose="False" CanDockInDocumentHost="False"

CanUserPin="False" t:RadDocking.SerializationTag="Ticket" ContextMenuTemplate="{StaticResource PaneContextMenuTemplate}">

<uc:TicketUserControl DataContext="{Binding TicketViewModel}" />

</t:RadPane>

</t:RadPaneGroup>

The problem is when I click in the usercontrol and start dragging, the radpane 'starts dragging'. On the attached picture, you can see that the name of the radpane appears at the bottom, but the radpane itself does not show that it is being dragged. That on itself is not a big problem. the big problem is when I do this on an item (a row) in the gridview. When I do this, sometimes the whole radpane disappears. And only restarting the program will reset the radpane.
So I guess that it is possible to drag the usercontrol (and with the usercontrol, also the radpane), even when the radpane is not.

Is this a bug or is there a property that I have to set on the usercontrol or radpane to eliminate this behavior?

Thanks in advance
Lowie

Localization of RibbonView QuickAccessToolbar menu

Hi,

I would like to show the RibbonView menu entries for customizing the Ribbon in a WPF application in German but found the documentation a little confusing.

>I copied Telerik.Windows.Controls.resources.dll into a de subdirectory of my referenced assemblies.

Do I still have to set the Current Culture? (I did but with no sucess).

The Silverlight documentation says something about a config file.

As I understand the entries should automatically in German (right now they are displayed in English).

Kind regards,
Peter

RadGridView perfomance issues as number of rows incresed

Hi,

In my wpf application i am using tab control. In first tab i am using list box to show the data and in second tab i am using rad Grid View to show data.

After loading both tabs when i switch the tab from grid view tab to list box then there is no delay in loading that view but when i switch back to the previous tab (Grid View) it takes some delay to load the data .

It seems like when number of rows increses in Rad grid view it creates some performance issues.

In tab switching it should not be a problem if we have loaded it already as it works perfect in listbox.

Is there any property to prevent this repopulation of rad grid view.

Looking forward for your reply .. It is really urgent.

Thanks
