I've been playing with a bunch of different charting engines trying to find wich one is right for our project.

Doing a binding like this:

<telerik:AxisY
AutoRange="False"
MinValue="{Binding Path=AxisProp.YMin}"
MaxValue="{Binding Path=AxisProp.YMax}"
Step="{Binding Path=AxisProp.YTick}" />

Seems to work, but for some reason it doesn't seem to work.

Looking at the debug information in the output window I see entries like this:
System.Windows.Data Error: 2 : Cannot find governing FrameworkElement or FrameworkContentElement for target element. BindingExpression:Path=AxisProp.YMin; DataItem=null; target element is 'AxisY' (HashCode=65127578); target property is 'MinValue' (type 'Double')

Any idea why this is failing?

Filtering with custom template

Hi

In my application, I have created a custom template that can display ID - Name pairs in one cell. The problem is, that I cannot use filtering in this case.

I have specified DataMemberBinding for the column, but instead of binding directly to a property, I use a converter on the Binding to retrieve the value from the data object (converter gets the id and the name and puts them in a string). The converter works well in Excel export, however filtering options is still missing in the GUI.

Binding bnd0 = new Binding(".");
   bnd0.Converter = new IDValueColumnToStringConverter();
   bnd0.Mode = BindingMode.OneWay;
...
return new GridViewDataColumn() {... DataMemberBinding=bnd0 };

Filtering icon is not displayed at all. Is there any workaround on this issue? Can I write custom filtering methods, but use the design of Telerik filtering dialogs?

Thanks for the help in advance,
   G. M.

[Solved] Documentation for Localization appears to be wrong

Hi,
We need a French version of the ScheduleView, so we translated what was not yet translated in the Strings.fr.resx file. Then, we implemented what's suggested in http://www.telerik.com/help/wpf/radscheduleview-localization.html using the resource manager technique. The documentation says to do the following:

LocalizationManager.Manager = new LocalizationManager()

{

ResourceManager = ScheduleViewResources.ResourceManager

};

but the ScheduleView was still showing in English. When I did the following:

LocalizationManager.DefaultResourceManager = ScheduleViewResources.ResourceManager;

it all started to work perfectly. That was tested in the most simple sample application.

Is it a bug in the documentation, is there something we're missing?
Thanks,

Francis
p.s. It would be nice if a fully French version of the Telerik's controls would be available as part of the package.

The type 'DataRowView' does not contain a public property named 'UnitColumn'

Hello,
I am running into the error: "The type 'DataRowView' does not contain a public property named 'UnitColumn'" error when trying to edit a cell in the radGridView cell. I am dynamically creating a DataTable to bind to. I have copied the xaml, along with the codebehind for a small sample that illustrates the issue.
Thanks for your help!
