Had migrated from .Net Framework to .Net8 and of course updated Telerik references, and I'm facing this problem rendering the chart.
using Telerik.Windows.Controls.ChartView;
using Telerik.Windows.Controls.Legend;
namespace Manager
{
public partial class CustomChartControl : UserControl, INotifyPropertyChanged
{
private const int YAXIS_STEP_NUMBER = 8;
private ChartSerieCollectionVM _viewModel;
private string _title;
public LinearAxis LeftAxis { get { return chart.Resources["leftAxis"] as LinearAxis; } }
public LinearAxis LeftCAxis { get { return chart.Resources["leftAxisC"] as LinearAxis; } }
public LinearAxis RightAxis { get { return chart.Resources["rightAxis"] as LinearAxis; } }
public LinearAxis RightCAxis { get { return chart.Resources["rightAxisC"] as LinearAxis; } }
public string Title
{
get { return _title; }
set
{
_title = value;
OnPropertyChanged("Title");
}
}
public DateTime ActualMaxDateTime { get; private set; }
public DateTime ActualMinDateTime { get; private set; }
public CustomChartControl()
{
InitializeComponent();
}
public void SetDataContext(ChartSerieCollectionVM series)
{
foreach (var serie in series.Series)
{
AsignSerieAxis(serie);
}
_viewModel = series;
DataContext = _viewModel;
}
private void AsignSerieAxis(ChartSerieVM serie)
{
if (serie.HorizontalAlignment == Telerik.Charting.AxisHorizontalLocation.Left)
{
if (serie.IsC)
{
serie.Axis = this.LeftCAxis;
}
else
{
serie.Axis = this.LeftAxis;
}
}

serie.Axis = this.RightCAxis;

This CustomChart is declared from other view as:
<TabItem x:Name="TabTotal" Header="Total">
<this:CustomChartControl x:Name="TelerikPowerChart" />
</TabItem>
TelerikPowerChart.Title = "Total Active Power";
TelerikPowerChart.SetDataContext(_viewModel.ActiveModel.PowerSerieCollection
If I had a static VerticalAxis
<telerik:RadCartesianChart.VerticalAxis>
<telerik:LinearAxis/>
</telerik:RadCartesianChart.VerticalAxis>
"No series added" message appears.
So it looks like the chart is rendered before the data is able to be binded. Is there any way to re-render the chart once the data is binded or to make the renderization waits for the data be binded?
