I am creating a RadCartesianChart which has a category of country name codes which I need to convert to a RegionInfo.DisplayName using a converter. I cannot figure out how to use a converter with CategoricalAxis?

 

                        <telerikChart:RadCartesianChart x:Name="Chart">
                            <telerikChart:RadCartesianChart.HorizontalAxis>
                                <telerikChart:NumericalAxis Location="Top"/>
                            </telerikChart:RadCartesianChart.HorizontalAxis>
                            <telerikChart:RadCartesianChart.VerticalAxis>
                                <telerikChart:CategoricalAxis PlotMode="OnTicks">
                                    <telerikChart:CategoricalAxis>
                                        <DataTemplate>
                                            <Label Text="{Binding Converter={StaticResource countryNameConverter}" />
                                        </DataTemplate>
                                    </telerikChart:CategoricalAxis>
                                </telerikChart:CategoricalAxis>
                            </telerikChart:RadCartesianChart.VerticalAxis>
                            <telerikChart:RadCartesianChart.Series>
                                <telerikChart:SplineAreaSeries ItemsSource="{Binding Data}">
                                    <telerikChart:SplineAreaSeries.ValueBinding>
                                        <telerikChart:PropertyNameDataPointBinding PropertyName="Value"/>
                                    </telerikChart:SplineAreaSeries.ValueBinding>
                                    <telerikChart:SplineAreaSeries.CategoryBinding>
                                        <telerikChart:PropertyNameDataPointBinding PropertyName="Category"/>
                                    </telerikChart:SplineAreaSeries.CategoryBinding>
                                </telerikChart:SplineAreaSeries>
                            </telerikChart:RadCartesianChart.Series>
                        </telerikChart:RadCartesianChart>

I have a long label which is returned from Category, but the LabelFitMode Multiline in the below chart on the VerticalAxis does not result in the label wrapping to another line.

 

Hi -

I have a list view that has "pull to refresh" enabled, and it works great -- refreshes and shows a spinner while it's refreshing.

 There are other situations that cause me to refresh the data, though, and in a ViewModel, and I'd like to have a property that I can update in the view model that could be bound to the "IsRefreshing" so that I can see the same refresh spinner when I am programmatically refreshing the data in the list view.

I can use an a Xamarin "ActivityIndicator" to show a spinner, but then when we "pull to refresh" we see BOTH spinners, and it looks bad.  This approach works fine for the programmatic-only refresh, but the pull becomes bad.  If I remove the activity indicator, then I don't see anything when the programmatic refresh happens.

 I see two options: Make it possible for me to set the "IsRefreshing" state for the ListView based on binding, or allow me to suppress the RadListView spinner in favor of the activity indicator - which would be seen then in both programmatic and pulls as the only indicator.

Let me know if I'm missing something or if this is possible.

I really appreciate the help and support.

Cheers -

Erik

Can I request a full working example of a couple of custom editors (perhaps the email and password Inputs idea from the documentation site would be a good candidate) but specific to Xamarin.Forms iOS?

 

The documentation is a bit thin and I can't seem to figure out how the custom editor exposes it's value for the validation logic to pick it up.

Also I couldn't find anything on how to properly position the content of the custom editor to match the location in the middle of the screen with the text left aligned like the other built-in editors would normally do.

 

Thanks

Hi,

I'm developing a Xamarin application targeting Android and iOS and I'm having some issues when trying to change chart's legend text color.

My hunch is that is something related to the palette, but I couldn't figure out where the problem might be.

Here is part of my code:

 

As you can see in the attached screenshot, legend text is grayed out. I'm expecting to see the text color black.

Am I missing something?

Many thanks in advance!

I have a RadListView with uneven row heights that I need to place inside a ScrollView in Xamarin Forms. Due to scrolling issues (on Android) I need to set the overall height of the RadListView to show all the rows.

How can I calculate the total height of all rows when they are dynamically sized according to their content?

Hi, Telerik Team.

I have a question regarding styling of the Calendar. Is it possible to make like that one? 
The biggest issue is that I need to have those 2 buttons beside Month name. 
How could I do that? Only renderers?

Best regards,
Maryan
