I have attached two pictures to demonstrate the issue.

The grid lines represent 1 minute intervals.

The first image shows the appointment being sized or dragged and it displays the start time and end time (2 to 3 minutes)

The second image shows the result when the appointment appears on the timeline.
Notice it is not aligned with the grid lines (should be between tick marks 2 and 3), I am not sure how to solve this offset problem..

Any help would be appreciated.

Touch swipe to scroll very slow on win8.1

Hello,

I have a RadComboBox (from the Q3/2013 release) with say 10 items and I am using the Windows8TouchTheme. On my win8.1 tablet the scrolling of the dropdown list is very (very, very) slow, when I swipe over the items. First nothing happens, then it scrolls a few items down or up. When I swipe over the scrollbar the performance is normal as expected.

Any ideas?

TabControl Background dosen't change with theme

Hello, i have a problem with background color of RadTabControl.
My project is using WPF. I have used RadTabControl and have some Tabs. For example i have a tab with a Grid. In the Grid i have some RadTextBox, RadComboBox and RadExpander. When i change the theme to Expression_Black in runtime, the themes of RadTextBox and RadComboBox will be changed automatically. But the Background colors of RadExpander and TabItems will not be changed.
Do i need to do something special for TabItems and RadExpander?
Thanks!

[Solved] Turning off auto-size feature of RadDiagramContainerShape

I touched on this topic in my last thread, but I'd like to ask this question in a more clear manner.

Is there a way to turn off the auto-sizing feature of the diagram containers?

Essentially I'd like to be able to specify the dimensions of a container regardless of its children. This would dramatically ease the rotation issues I've been seeing as they are all tied to the container resizing itself during moving/rotation operations.

Thanks!

Setting ScaleObject properties on GaugeRange work in Xaml, not in code

In my scenario, I have an unknown number of ranges at run time. So, I have to create them in code, set their properties, and add them to a scale. I need to move the range well inside of the scale, so I use the ScaleObject.Location and ScaleObject.Offset properties to achieve that look. Below is a sample window's xaml showing a single gauge (windows 8 implicit style)

<Window

xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"

xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" mc:Ignorable="d" x:Class="NoXamlTest.MainWindow"

Title="MainWindow" Height="274" Width="426">

<Grid>

<Grid.RowDefinitions>

<RowDefinition Height="Auto"/>

<RowDefinition Height="*"/>

</Grid.RowDefinitions>

<Button Width="75" Height="23" Click="Button_Click" Content="Default"/>

<telerik:RadQuadrantNEGauge Grid.Row="1">

<telerik:QuadrantNEScale Min="1" Max="5" MajorTicks="4" MiddleTicks="1">

<telerik:QuadrantNEScale.Indicators>

<telerik:Needle Value="3.28" OffPosition="0"/>

<telerik:Pinpoint/>

</telerik:QuadrantNEScale.Indicators>

<telerik:GaugeRange x:Name="MyGaugeRange" Min="1" Max="5"

StartWidth=".05"

EndWidth=".05"

Stroke="Black"

StrokeThickness="1"

telerik:ScaleObject.Location="Inside"

telerik:ScaleObject.Offset="0.15*"

>

<telerik:GaugeRange.Background>

<LinearGradientBrush StartPoint="0,0" EndPoint="1,0">

<GradientStop Offset="0" Color="Green"/>

<GradientStop Offset="1" Color="Red"/>

</LinearGradientBrush>

</telerik:GaugeRange.Background>

</telerik:GaugeRange>

</telerik:QuadrantNEScale>

</telerik:RadQuadrantNEGauge>

</Grid>

</Window>

In case these things are important, there are some oddities in Expression Blend (2012) when changing the ScaleObject properties: Blend does not recognize the change until the project is built, using the ScaleObject properties causes Blend to not display the indicator. Here is the designer in Blend (after the project is built) where you can see that the range is in the expected location:

Here is the windows actually running (where the indicator is visible).

My real issue is that I have to set those ScaleObject properties in code. So, I remove the xaml above that sets the ScaleObject properties & instead set them in code when the button at the top of the window is clicked. That code is:

private void Button_Click(object sender, RoutedEventArgs e)

{

GaugeRange range = FindName("MyGaugeRange") as GaugeRange;

range.SetValue(ScaleObject.LocationProperty, ScaleObjectLocation.Inside);

range.SetValue(ScaleObject.OffsetProperty, new GaugeMeasure( 0.15, GridUnitType.Star));

}

The result is that nothing happens. Am I doing something wrong, or is there a different way to move the range the way I want via code?

Thanks - Mitch

Carousel crashing after last update

After the last update I did for my telerik products I started getting error reports from my user base. I didn't change anything to do with the carousel on my last release. I am attaching the error in a png file, let me know if anyone has any ideas. I have also had a long standing issue with the carousel where I change the selected item from code behind and if I have more than 5 items in the carousel, the third item will be brought to the top instead of the selected item. I do have code that I use to make sure that the items stay in view. But I can't see why the carousel is changing position, I had to set my selected item to null and then to the value I wanted it to be. So the carousel changes to the third item in the list then after setting it to null and back to my item it will select it properly.

Thank you
