DateTimePicker moving cursor automatically

In the DateTimePicker, if the user enters an 11 first, then I would like to assume that they mean November and automatically move them to the day section. Similarly if the user enters a 5 in the day section I'd like to move them to the year section since 5x is not a valid day choice. Additionally, I would like to have the text box section of the DateTimePicker set up with a mask. So that when the user starts typing they see 00/00/0000 and as they type they overwrite the zeros so that there are 8 numbers and two slashes in the DateTimePicker textbox at all times. Is this possible with the DateTimePicker?

Error after upgrading from Telerik Q32009 to Q2 2010

I have some aggregrate functions on my gridview like this
groupview = new QueryableCollectionView(MyListGrid.Items);
                    if (MyListGrid.GroupDescriptors.Count > 0)
                        MyListGrid.GroupDescriptors.Clear();
                    var descriptor = new GroupDescriptor() { Member = "Status" };
                    descriptor.AggregateFunctions.Add(new CountFunction());
                    this.MyListGrid.GroupDescriptors.Add(descriptor);

and I get the following exception at descriptor.AggregateFunctions.Add(new CountFunction());

{"Unable to cast object of type 'Telerik.Windows.Data.QueryableCollectionViewGroup' to type 'Telerik.Windows.Data.AggregateFunctionsGroup'."}

Lost Focus and Get Focus Event of RadWindow

Hello,

I have a radwindow as my parent window and a click on the status bar items opens another Radwindow. I need to close the child window when I click anywhere outside the child window.

To do so I have registered the window.GotFocus(..) event on the Parent Window. In this event I am closing the child window. Also I have registered the LostFocus event on tyhe child window But this event gets fired only when I hit a Tab. If I click anywhere outside the Radwindow neither of the event get fired.

Is there any way to resolve this issue?

Thank you for your help.

Treeview not updating list items

Hello Telerik!

I have created an example similar to your file explorer treeview example. I am having trouble getting the list to automatically update if a text file is added. I am not looking for a filewatcher solution, just something simple where a function is called once the file has been added.

Please check out my example here

To get it working add a c:\foo directory and at least 1 text file. The desired result would be to have the treeview automatically update once the add file button is pressed.

Thanks. You guys are the best!
Ryan

Themes don't apply to TabControl

Hi guys,

I'm currently evaluating RadControls and I can't get themes to work with RadTabControls and their RadTabItems.
I apply one of the built in themes to the application, eg

Telerik.Windows.Controls.StyleManager.ApplicationTheme = new Telerik.Windows.Controls.SummerTheme();

...and it works with the other controls but not tabcontrols/tabitems. Is there anything else I have to install/do?
