FIX. RadChartView - corrupts legend when set Series IsVisibleInLegend = False in Properties at design time

RadChartView Control: corrupts legend when set Series IsVisibleInLegend = False in Properties at design time

Simply added a few extra series , and then tried to turn them off in the legend 

screen shot shows too many legent items for the series in the properties window

Thank you for the detailed explanation. I managed to replicate the issue and I am going to change its status to approved. We will work in its resolution in future.

Meanwhile, you can setup your chart at design time, but set the IsVisibleLegend property in code, at runtime.

new prj
add radchartview as rcv
select series 
add 2 x scatterseries  RC1, RC2
add 2 x scatterLineseries  RCL1, RCL2
nb. (we only use scatterseries and scatterlineseries)
As add each set legendtext
rcv.showlegend = true
save all
go back into rcv.series properties
select series and make RC1.IsLegend = false (see legend text disappear from rcv)
select series and make RLC2.IsLegend = false (see legend text disappear from rcv)
close series propeties
(ERROR: now see all 4 series in the legend not 2 as expected)
save all
go back and add an extra couple of series RC3, RCL3

now I have series 0,4,5 all with IsVisibleInLegend= false yet have 5 legend text items not 3
on closing series properties form I have all 6 series in the legend on the form
save all
and then close form
reopen form
Get Exception as reported in another bug report


Machine generated alternative text (appears 3 times (one for each series thats set to false):
Error setting property "15VisibIeInLegend" in class 
"Telerik.WinControIs.UI.CatesianSeries" to value "False". 
The error was: 
System.NuIIReferenceException: Object reference not set to an instance of an 
object.

Hi Ian,

I am still unable to get a clear picture of the scenario. Would you be able to describe it in a step by step matter. Once I am able to replicate the issue, I will be able to approve it.

apologies added the wrong attachment

When I close my custom control and reopen it - they are again synchronized
