Hi,

I have a RadGridView, what I need is to style the cell so that when data type is some series, it can be represented with Bar/line/Area or Pie chart.

For example, if the data type is basic types, int/string/bool etc, it just shows as is. And if the data type is series, then by default, uses Pie chart. On top of that, user can change the representation from Pie to Bar/line/Area with a drop down selection.

I hope my question is clear and this is the correct place you could help me with it.

Many thanks.

[Solved] How can I initiate (raise) BeginningEdit event without of using of RadPropertyGrid.BeginEdit method?

I write WPF MVVM Prism 6 application and try to use RadPropertyGrid. How can I initiate (raise) BeginningEdit event without of using of RadPropertyGrid.BeginEdit method? I cant call BeginEdit method because my application is pure MVVM one and I don't use codebehind. If I simply change the value of the property by typing the value of selected property then BeginningEdit event is not raised. Is there a way to initiate BeginningEdit event in MVVM application without call of BeginEdit method?

Assembly 'Telerik.Windows.Themes.Green' is not referenced by this project.

I am trying to follow the instructions from: http://docs.telerik.com/devtools/wpf/styling-and-appearance/styling-apperance-implicit-styles-overview.html#applying-theme-globally-in-your-application From the picture below you can see that it definitely is in my list of References. I apologize if this is a stupid question as I am fairly new to WPF (WinForms was my thing).

http://i.stack.imgur.com/fBtbQ.png

I included a Theme's Folder and put the XAML files into that. I am able to reference them with out error but it does not seem to want to apply the theme to my button type:

As you can see in the picture I have tried using the dll files as references but it doesn't they they are referenced.

Anyone able to tell me why it is not able to use the Theme Green dll Reference?

Multiple Axes in RadPolarChart

Hi,

I have a PolarChart with multiple series. The problem is that the scale of the two series is entirely different and when I plot them I am unable to see the one with smaller values.

Is there a way in RadPolarChart similar to RadCartesianChart where I can specify a different axis to plot the second series and also a different location for the secondary axis.

Thank You

Problem with header in Office2013 theme

Hello,
the Office2013 theme corrects the text of the header so that they are in uppercase.
This work correctly when we just set the header as a text, but not if we want to customize it, for example to add an image or something else. It seems that the theme takes the Text property of the header content, converts it to uppercase and use the result to display in the header. If the header content doesn't contain a Text property, nothing is displayed.

To see this in action, just create a WPF application, add the relevent assemblies and replace MainWindow.xaml with:

<Window

x:Class="Test_GridView_header_Office2013.MainWindow"

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

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

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

Title="MainWindow" Height="350" Width="525">

<tk:RadGridView Margin="10">

<tk:RadGridView.Columns>

<tk:GridViewDataColumn Header="Direct text" />

<tk:GridViewDataColumn>

<tk:GridViewDataColumn.Header>

<StackPanel>

<TextBlock Text="Header with a stack panel" />

</StackPanel>

</tk:GridViewDataColumn.Header>

</tk:GridViewDataColumn>

</tk:RadGridView.Columns>

</tk:RadGridView>

</Window>

If you run the application, you will see that the first header is displayed, but not the second one...
In all other themes I tested, including Windows8, both headers are displayed.

To correct the problem, I think that the best solution is to check whether the header has a Text proprty. If there is none, you should display the header as defined by the user, without changing it.

[Solved] Grouping in RadGridView - crash

Hello, I am getting the following exception when using grouping in RadGridView. The problem is that the exception seems to happen not inside my code,
but entirely inside Telerik RadGridView control, so I cannot catch the exception. Any tips how to catch this exception or better - avoid the exception from occuring? I using the Telerik version 2016.1.217.40. My twitter handle is @Tore_Aurstad. Nice if you got any tips, we are closing in on our release date for our client which is using the Telerik WPF library heavily.

Thanks,
