I've added a resource file to my WPF application and in it I have:

<ResourceDictionary 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">

<Style TargetType="telerik:RadGridView" BasedOn="{StaticResource {telerik:ThemeResourceKey ThemeType=telerik:Office_BlueTheme, ElementType=telerik:RadGridView}}" />
</ResourceDictionary>

and in App.xaml I have:
<Application.Resources>
   <ResourceDictionary>
   <ResourceDictionary.MergedDictionaries>
   <ResourceDictionary Source="Dictionary1.xaml" />
   </ResourceDictionary.MergedDictionaries>
   </ResourceDictionary>
   </Application.Resources>

And in a usercontrol I've added a RadGridView; Now the group section and gridline borders are blue but the header remains black.
why the theme dosen't apply to column header?

How can I set ColumnGroup-Header programmatically?

Hello!

I have a grid with columns and columngroups, which I declare in XAML. According to the time periods of the data, which should be displayed, I have to change to header of the columngroups.

I tried something like ...

GridViewColumnGroup colGrp = rgvAbsaetze.FindName("xcolGrpMon" + i) as GridViewColumnGroup;

colGrp.Header = aktueller_Monat;

... but the colGrp stays null.

How can I achieve this?

Kind regards

Michael

P.S.: I'm new to WPF!

Chart runtime exceptions in your samples

When you run your samples for the Chart control to look at the 3d pie chart, these errors are thrown. Your code is a pretty simple bind to IEnumerable. What should I do to avoid this when plugging your charts into my app?

System.Windows.Data Error: 23 : Cannot convert '{DisconnectedItem}' from type 'NamedObject' to type 'System.Collections.IEnumerable' for 'en-US' culture with default conversions; consider using Converter property of Binding. NotSupportedException:'System.NotSupportedException: ReferenceConverter cannot convert from MS.Internal.NamedObject.

Problem with Negative Values on Masked Input

I am trying to resolve an issue with weird behavior on a RadMaskedCurrencyInput control when entering negative values. I believe you would experience similar issues with other masked input controls. I currently have this control:
<telerik:RadMaskedCurrencyInput />
If you run this and try to enter -500 for example, the textbox does not take in the negative. You have to type the 500, then the "-" for the textbox to recognize the negative value.

I have also noticed that if you load the control with a default value, then the negative is recognized when you type it in.
<telerik:RadMaskedCurrencyInput Value="51.64" />

Basically, try this control without a default value and you will see some pretty funky behavior when trying to enter a negative number.

Any feedback will be helpful.
Thanks.

Custom Theme Brushes

Hi,
I just read in your wpf documentation section to change theme brushes for Metro Custom theme. i.e.

MetroColors.PaletteInstance.MainColor = Colors.Black;
MetroColors.PaletteInstance.AccentColor = Colors.Orange;
MetroColors.PaletteInstance.BasicColor = Colors.DarkGray;
MetroColors.PaletteInstance.StrongColor = Colors.Gray;
MetroColors.PaletteInstance.MarkerColor = Colors.LightGray;
MetroColors.PaletteInstance.ValidationColor = Colors.Red;

Can i do the same for other telerik themes like Windows7Theme?

Grid, DataForm, Data Filter in code not xaml

Anyone know of C# code examples that show a RadDataFilter, RadGridView, and RadDataForm all using the same "Source"?
Something like this?

IEnumerable<MyClass> SomeResults;

SomeResults = GetResults();

MyDataForm.ItemsSource = SomeResults
MyDataFilter.Source = SomeResults;
MyGridView.ItemsSource = SomeResults;

I know in xaml you can do something like this for the grid
{Binding FilteredSource, ElementName=MyDataFilter}

but I have no idea how to pull this off in C# code.

When I scroll my grid, the Dataform does not move. When I select next in my dataform, the Grid selection does not move, and when I apply a filter, nothing gets filtered.

This setup (Filter, Grid, dataform) will be used to display items from multiple sources, therefore I have to do it all in code.

Thanks for any help.

Jeff
