Questions on UI for WPF Forum

As I know, in case of no data, the chart shows the text "No data to plot" by default.
ChartView provides 2 properties to customize the no data content and style, they are EmptyContent and EmptyContentTemplate.

The strange thing is - The chart still show the default text if its EmptyContent is bound to a view model property, but if the customized text is set to EmptyContent directly in xaml then it works well.

I made the same settings to VerticalAxis - bind Title and set TitleTemplate and didn't has this problem.

Any suggestion? Thank you.

Conditional Formatting

Hi,

i am currently evaluating some of the Telerik-Controls. So i created a sample project.
Now i have one question related to the Spreadsheet Control:

There was functionality included in the roadmap:
Conditional Formatting
Applying different visual settings to cells based on the data they contain allows you to identify variances in a range of values with a quick glance. The feature is very useful for comparing values, selecting rows dynamically and spotting duplicates easily.

Is Conditional Formatting included in the current WPF-Spreadsheet? I also tried out the demos but i was not able to find the fomatting.

I also wrote an email to the Trial-Support, but i do not receive an response :(.

Thank you very much!
Andy

We have multiselect set to true on the grid. Can anyone demystify the stack below as to why this is happening?

Thanks

<Setter Property="IsSelected" Value="{Binding Path=IsSelected, Mode=TwoWay}"/>

this.UseCase.Items.Clear();

this.UseCase.AddItems(this._products);

this.UseCase.FrameViewModel.ProductGridVM.Products = this.UseCase.Items;



We're restoring IsSelected after this.

ProportionalGradient on RadRadialGauge

Hi,
I'm working with RadRadialGauge and I want to color the BarIndicator with a ProportionalGradient similar to a linear gradient on more colors (Ex. green, yellow and red). I have seen that this option works on RadHorizontalLinearGauge, I would like to obtain the same thing with a RadRadialGauge.
Can someone help me?

I have attached an example of solution with the two kinds of RadGauges and an image with the desiderata.

Thanks a lot

RadCartesianChart LineSeries problem

Hello,
I am using RadCartesianChart for my project and I need to show the data I have with Line Series.
I am able to show it with BarSeries, but I cannot do the same with LineSeries.
This is my code for the data binding

<telerik:RadCartesianChart.Series>
<telerik:BarSeries CategoryBinding="date" ValueBinding="value" ItemsSource="{Binding}">
</telerik:BarSeries>
</telerik:RadCartesianChart.Series>

However, when I use the following code
<telerik:RadCartesianChart.Series>
<telerik:LineSeries CategoryBinding="date" ValueBinding="value" ItemsSource="{Binding}">
</telerik:LineSeries>
</telerik:RadCartesianChart.Series>

it gives me the error:
Error 1 Ambiguous type reference. A type named 'LineSeries' occurs in at least two namespaces, 'Telerik.Windows.Controls.ChartView' and 'Telerik.Windows.Controls.Charting'. Consider adjusting the assembly XmlnsDefinition attributes. C:\Users\.......

And in Window I only have this:
<Window ...
....
xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"
... />

How do I fix this?
