Hey,

I'm creating a proof of concept to test the telerik calendar control. We designed a design for this control but we're having a problem with styling the DayButtonStyle.
We like to change the looks of the buttonchrome in this control because it looks awfull with our design. It is no problem to change this style but when we change the style and we are going to the next month, the days are not refreshing. The days are in the same place as the month before what isn't correct in this new month.

Is there something I am missing? Or is there a solution for this issue? There is not much to find about styling these buttons or issues with it.

RadGridView and Errors in bound DataTable

Hi guys n gals,

I have noticed that if I use SetColumnError on a DataTable with a GridView bound to it (WPF, MVVM) then I don't see the error inidcator appear on the GridView.

Is this intentional? If so, I find the GridView to be missing some be pretty basic functionality...

Y-Axis IsLogarithmic Property and Pointmarks

I have a chart which implements a Logarithmic Scale for the Y-Axis as described here:
http://www.telerik.com/help/wpf/radchart-features-axes-logarithmic-scale.html

I some cases, when the IsLogarithmic Property is toggled for Line Series types, the Point Marks become skewed. The lines themselves seem to be plotted correctly, but the Point Marks will appear in their old positions. This behavior only occurs for only certain data sets.

Below is an example which demonstrates the problem.

XAML:

<Window x:Class="LogarithmicScale.MainWindow"

Saving layout does not work properly when the gridview contains a GridViewToggleRowDetailsColumn

Hi team,

I've got a problem with the PersistanceManager. I'm using the routines from the demo for saving and loading the layout of the gridview. The data is saved in the isolated storarge. My gridview contains a GridViewToggleRowDetailsColumn.

When I start the application, don't change the layout, save the layout, restart the application and load the layout from the isolated storage the displayindex is deferred. When I remove the GridViewToggleRowDetailsColumn, save and load works fine.

<telerik:GridViewToggleRowDetailsColumn Header="+" HeaderTextAlignment="Center" x:Name="MainToggleColumn"/>

Please take a look at the attached screenshots. The first one (hc_110.jpg) displays the layout before saving. The second one (hc_111.jpg) displays the layout after restarting the application and loading the layout.

Do you have an idea how to find a solution for this?

Best regards

RadWindow resizing to content

I would like a side panel to expand the window size like the behaviour in this code:

<Window x:Class="WpfApp.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" SizeToContent="WidthAndHeight">
<DockPanel Height="300">
<CheckBox x:Name="checkbox" Width="200" IsChecked="True" />
<Grid Width="200" Background="Blue">
<Grid.Style>
<Style TargetType="{x:Type Grid}">
<Style.Triggers>
<DataTrigger Binding="{Binding ElementName=checkbox, Path=IsChecked}" Value="True">
<Setter Property="Visibility" Value="Visible" />
</DataTrigger>
<DataTrigger Binding="{Binding ElementName=checkbox, Path=IsChecked}" Value="False">
<Setter Property="Visibility" Value="Collapsed" />
</DataTrigger>
</Style.Triggers>
</Style>
</Grid.Style>
</Grid>
</DockPanel>
</Window>

The RadWindow does not seem to resize itself, even when setting SizeToContent="True". Is it possible to do this with RadWindow?
