1) create new project with a radScheduler
2) add a new appointment with a subject of: <>
3) program will crash with System.InvalidOperationException: 'Collection was modified after the enumerator was instantiated.'
The program will crash even if you have additional text before the "<>" but having text after it will allow the program to continue running however, none of the text after the "<>" will display.
Hello, Logan,
Following the provided information, I was able to replicate the error message:
I have approved this bug report.You can track its progress, subscribe for status changes and add your comments on the following link - feedback item.
I have also updated your Telerik points.
Currently, the possible solution that I can suggest is to disable the HTML text rendering:
public RadForm1()
{
InitializeComponent();
this.radScheduler1.AppointmentFormatting+=radScheduler1_AppointmentFormatting;
}
private void radScheduler1_AppointmentFormatting(object sender, SchedulerAppointmentEventArgs e)
{
e.AppointmentElement.UseHtml = false;
}I hope this information helps. If you need any further assistance please don't hesitate to contact me.
