Based on your description, the date time culture is more likely causing the problem. For your information, it needs to use EN-US date time culture for now. If you want to change it, you need to configure recurring in your format.

We will provide the project template that fix this problem in the upcoming SP1 of Intersoft WebUI Studio 2011 R2.

How do i reconfigure it?

Apologize for the delay in sending this.

I use CultureInfo.InvariantCulture to rectify the DateTime.Parse problem that persist when user create a project using UXRibbon project template (Intersoft ClientUI Ribbon Application) on a PC where the regional settings of the PC is EN-US. The list below shows the step-by-step to have the project run on your end.

1. Create a new project using the Intersoft ClientUI Ribbon Application project template.
2. After the project is created, open the MailMessage.cs model class.
3. Find following code
   

   this._date = x.Element("SendDate").Value != null ? DateTime.Parse(x.Element("SendDate").Value.Trim()) : DateTime.MaxValue;

   
   and modify the code into the following. (*System.Globalization namespace is required)
   

   this._date = x.Element("SendDate").Value != null ? DateTime.Parse(x.Element("SendDate").Value.Trim(), CultureInfo.InvariantCulture) : DateTime.MaxValue;

4. Open TrainingEvent.cs model class.
5. Find following code
   

   ...
   this._endDate = x.Attribute("EndDate") != null ? DateTime.Parse(x.Attribute("EndDate").Value.Trim()) : DateTime.MaxValue;
   ...
   if (x.Attribute("ExceptionDate") != null)
       this._exceptionDate = DateTime.Parse(x.Attribute("ExceptionDate").Value.Trim());
   ...
   this._startDate = x.Attribute("StartDate") != null ? DateTime.Parse(x.Attribute("StartDate").Value.Trim()) : DateTime.MaxValue;
   ...

   
   and modify the code into the following. (*System.Globalization namespace is required)
   

   ...
   this._endDate = x.Attribute("EndDate") != null ? DateTime.Parse(x.Attribute("EndDate").Value.Trim(), CultureInfo.InvariantCulture) : DateTime.MaxValue;
   ...
   if (x.Attribute("ExceptionDate") != null)
       this._exceptionDate = DateTime.Parse(x.Attribute("ExceptionDate").Value.Trim(), CultureInfo.InvariantCulture);
   ...
   this._startDate = x.Attribute("StartDate") != null ? DateTime.Parse(x.Attribute("StartDate").Value.Trim(), CultureInfo.InvariantCulture) : DateTime.MaxValue;
   ...

6. Save all the changes and run the project.

Another DateTime.Parse problem persists when the UXScheduleView is loaded. This problem comes from the internal code of UXScheduleView. But please don’t worry, since the development of UXScheduleView has managed to fix this problem.

The hotfix will be released within this week or two. Please download and apply the hotfix to fix the issue.
