Asynchronous assignment of Bing Provider

Hi,

I am using WCF data service to fetch spatial objects (polygon) from SQL Server database and render them on the information layer.Everything was working fine until I decided to have my calls Asynchronous, in which I have a callback method to assign my polygon list to a bind-enabled property on my ViewModel (PRISM).My view used to be slow and would hange due to both the synchronous WCF call and the bing provider assignment which seems to freeze the UI. Now my WCF call is Asynchronous and does not freeze the UI, but the bing provider assignment is still freezing the view for about 2 to 3 seconds.Is there any plan to change this provider effects on the UI ?

Thanks

[Solved] Changing the RadPane height

I've got a RadSplitContainer that contains three RadPaneGroup each with one RadPane. On a certain event, I want to "shrink" one of the RadPanes. Changing the RadPage height or maxheight didn't seen to make a difference but changing the parent RadPaneGroup does.

So in my code right now, on one click event when I want my RadPane to shrink, I change the RadPaneGroup's MaxHeight to 50. When I want it to expand again, I change the RadPaneGroup's MaxHeight back to PositiveInifinity. This works well but as soon as I change the height of the RadPaneGroup itself by grabbing the little separator between each RadPaneGroup with my mouse and dragging it; when my collapse event fires, the RadPaneGroup gets shrunk too much or not enough depending on whether I changed the height to be bigger or smaller than before.

It appears the value I set the MaxHeight to needs to change dynamically depending on the current ActualHeight of the RadPaneGroup but I can't seem to find at what factor this needs to change by or, more baffling, why it appears to be opposite depending on the way I changed the height of the RadPaneGroup (for example, if I make it bigger, I have to use a smaller number for the MaxHeight).

So first off, am I doing this wrong by playing with the MaxHeight? If not, how can I get this control whether it be the parent RadSplitContainer or the individual RadPaneGroups to change their height from/to a specific value and from/to infinity (fill)?

EDIT: I've also found that when I "shrink" the middle RadPaneGroup, it doesn't work the first time... then I expand it and shrink it again and, while it works, there is a large gap between it and the top RadPaneGroup.

Keyboard focus indicator

I've run into some somewhat strange behavior.

As I hover over items, the item gets highlighted in yellow. But if I then switch to navigating with the keyboard, the highlighted item is still shown, and now it's confusing as to which highlight is indicating the selection.

Is this expected behavior, and is there a way to control it?

[Solved] Horizontal Linear Gauge Resize Problem

I am using a linear gauge set to horizontal orientation inside a User Control class. Because of the number of different ways that a user needs to be able to configure this control class I am building the whole gauge in the code behind and none in the xaml. When I go to re-size the gauge by dragging it horizontally then the scale will re-size appropriately in the height and width dimensions, but when I attempt to re-size the control vertically the scales height and width will not decrease with the re-size of the control. This will happen until the scale is covered up by the bottom edge of the gauge. How can I get the scale to correctly size within the UserControl?

I have attached screenshots to see how the control looks when it is re-sized vertically and horizontally.

Thanks for any help.

The first code sample creates the gauge in the codebehind and the second code sample keeps the top of the scale in the correct spot when re-sizing.

private void SetupHorizontalSlider()

{

//clear the grid of any controls before setting up a control

layoutRoot.Children.RemoveAt(0);

//create the RadGauge

mGaugeControl = new RadGauge() { Name = "mGaugeControl" };

//create the LinearGauge

LinearGauge linearGauge = new LinearGauge();

//add the LinearGauge to the RadRauge container

mGaugeControl.Content = linearGauge;

//create the LinearScale

LinearScale linearScale = new LinearScale()

{

Name = "linearScale",

Min = 0,

Max = 10,

StartWidth = 0.1,

EndWidth = 0.1,

StrokeThickness = 1,

MajorTicks = 10,

MiddleTicks = 1,

MinorTicks = 5,

Orientation = Orientation.Horizontal,

Left = 0.15,

Top = 0.13,

RelativeHeight = 0.70

};

linearScale.MajorTick.Length = 0.01;

linearScale.MajorTick.TickWidth = 0.1;

linearScale.MajorTick.Location = ScaleObjectLocation.OverCenter;

linearScale.MiddleTick.Length = 0.025;

linearScale.MiddleTick.TickWidth = 0.5;

linearScale.MiddleTick.Location = ScaleObjectLocation.OverCenter;

linearScale.MinorTick.Length = 0.02;

linearScale.MinorTick.TickWidth = 0.3;

linearScale.MinorTick.Location = ScaleObjectLocation.OverCenter;

linearScale.SizeChanged += new System.Windows.SizeChangedEventHandler(linearScale_SizeChanged);

linearScale.Label.Location = ScaleObjectLocation.Inside;

//add the RadialScale to the RadialGauge Items collection

linearGauge.Items.Add(linearScale);

//use the marker styled in the resource section of this page

mMarkerTemplate = this.Resources["HorizontalTopMarkerTemplate"] as ControlTemplate;

//create the LinearBar indicator and add it to the indicators collection

mLinearBar = new LinearBar()

{

Name = "bar",

Location = ScaleObjectLocation.OverCenter,

EmptyFill = System.Windows.Media.Brushes.Transparent,

Background = System.Windows.Media.Brushes.Green,

IsAnimated = true,

Duration = new Duration(TimeSpan.FromSeconds(2)),

Value = 2

};

linearScale.Indicators.Add(mLinearBar);

//create marker indicator to add to the indicators collection

mNeedle = new Marker()

{

Name = "needle",

Template = mMarkerTemplate,

IsAnimated = true,

Duration = new Duration(TimeSpan.FromSeconds(2)),

Location = ScaleObjectLocation.OverCenter,

RelativeHeight = 0.1,

RelativeWidth = 0.09,

Value = 2

};

linearScale.Indicators.Add(mNeedle);

//register the needle with the page so that the animation will work correctly

RegisterControl(mNeedle.Name, mNeedle);

RegisterControl(mLinearBar.Name, mLinearBar);

//create NumericIndicator to add to the RadialScale Indicators collection

//mValueIndicator = new NumericIndicator();

mGaugeScale = linearScale;

mGauge = linearGauge;

layoutRoot.Children.Add(mGaugeControl);

}

void linearScale_SizeChanged(object sender, System.Windows.SizeChangedEventArgs e)

{

((Telerik.Windows.Controls.Gauges.LinearScale)(sender)).Top = (e.NewSize.Height / e.NewSize.Width) / 2;

}

Do not favor quantity over quality!

Hi there,

a lot of guys are right: it seems to be neccessary to wait for the first service pack of a new Telerik version. :-(

This was the same procedure with ANY new version in the past... this is not a very good recommendation for the QA at Telerik, I guess.

You should not favor QUANTITY over QUALITY. It is very, very frustrating to find several new bugs in *existing controls* in every new release of the controls and to wait for the service pack for several weeks.

We tested the new 2012.1.0215 version in our current project (it uses several WPF controls from Telerik). And after some minutes of testing, we found 4 really severe bugs. Basic stuff, which worked totaly fine the 2011.3.1220 version...

So we had to switch back again (as allways).

Look at DevExpress (I worked with their controls for years in the past): they seem to have a much better QA than Telerik. I never had such problems with new bugs in new versions of WPF/WinForm controls at DevExpress.

Come back to QUALITY and good QA, guys! Your customers want to have stable and bugfree controls. Invest more in QA of existing functionality instead to produce more and more fancy controls for the kids in the block!

A very frustrated customer.

RadCarousel autosize to fit image

Hi,

in my WPF project, I fill dynamically images to a RadCarousel. I bind the ItemsCource to a List<Image> variable. I would like to know how I can specify to the carousel to strech all images to take maximum space available space keeping their aspec ratio.

Actually, I have a small carousel with thumbnails, when a user the click on an image, I take all related images and then, transfert it into another window with a bigger carousel. The problem is, most of the images are bigger than the height of the screen resolution. I would like thoses images to shrink into the display area to prevent loosing details on the image. I need the smaller images to grow to maximum size,

Thank's

Custom Tick Bar

Hi,

Is there a control for just displaying the tick marks (with labels) that you would normally see attached to a slider control? I was hoping RadTickBar would do it, but the documentation doesn't seem to elaborate on whether it's possible to use it on its own or not.
