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.

InvalidOperationException when group/sort one of the two grids binded on one ListCollectionView

Hi,
I've got an error when i try to group my data by using the drag an drop of one of the columnheader. The only thing noticeable is there is two grids binded over one ListCollectionView because the same data are displayed in several place in my application.
I've made a little sample to reproduce the problem, just drag the Name colum header to the group panel or click on it to sort the datas.

I don't understand what's happen :(
