Fiscal Quarters?

Is there a way to easily change the quarter numbering to align based on a fiscal calendar vs "calendar" year?

Thanks,

Validation with EF4.1 and DataAnnotations

Hi,
i have spent the last two days two find out how the validation works in the dataform. My DAL uses Entity Framework 4.1 with auto generated POCO Entities (in a seperate Assembly).
I'm working with MVVM and have UserControls for my views. One UserControl has a RadDataFrom with customized fields. The currentItem is bound to a an instance of my POCO Entities. Now i'd like to use DataAnnotations in the entities for my validatioin. But the error are not displayed in the dataform. I don't know what i'm doing wrong, can you please help me?
Here is the UserControl containing the dataform and the corresponding POCO:

<UserControl xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation" x:Class="MiexProto.Views.EmployeeFormView"

Show appointment with no time span

My project requires that the user should be able to create an appointment with a matching start and end time. The scheduleview does not complain about doing this but it will not display. Obviously because there is no time span to display. However, I do need these to show up. Outlook shows these 0 time appointments, so must I. I've tried setting min height/widths on appointments but it seems to get ignored. Any help?

Thanks,
Greg

Use IDataErrorInfo With RadGridView

Hi Support

We implement IDataErrorInfo for our Data, when we enter invalid data in edit mode it shows red box but when we update it to old data it doesn't change and still shows invalid data and error message and let us pass the cell.

We don't use cell validation and we use MVVM pattern.

thanks in advance,
Mehri

public partial class DataDictionary : IDataErrorInfo

{

#region IDataErrorInfo Members
public string Error

{

get

{

return null;

}

public string this[string columnName]

{

get

{

if (columnName == "Name")

{

if (Name == null || Name == string.Empty)

return "Name cannot be null or empty";

}

else if (columnName == "Code")

{

if (Code == 0)

return "Code Cannot be zero";

}

return "";

}

#endregion

}

ValueChanged event doesn't fire as they are typing

I have two updowns and a label. The label is updated with the sum of the values entered into the two updowns. I wired up the ValueChanged event to both updowns to call a method that does the calculation and then put the sum into the label.

It works, but it appears to behave like a text input in IE such that it only fires when the control loses focus. The client needs to be able to see the values calculate as they type.

I tried using KeyDown, but it doesn't work because the UpDown still has focus and the value isn't evulated as changed until the control loses focus.

Is there a way to work around this?

Gridview with Open Access DSW

Hi,
I have followed the Open Access dsw tutorial (http://www.telerik.com/help/openaccess-orm/getting-started-root-quickstart-wpf-overview.html) so that I have generated only a single .generated.cs from one view on my SQL server.

How do I link this to the RadGridView? I have tried following your tutorials, however, a severe lack of skills on my part, has proven this to be a difficult task to carry out. If would also be great if I could display the filters for each heading as well.

Cheers. Any help is appreciated.

Regards, Al.
