I've spotted a few omissions in the documentation, mainly in the 'What's New' areas, so I just thought I'd point them out. Overall, the documentation is much improved - many thanks for that.

• Overall 'What's New' is still for Q2.
• RadGauge 'changes and backwards compatibility' still for Q2
• RadScheduler ditto
• RadGauge ditto
• RadTreeView 'changes' section is empty
• RadTabControl 'changes' section is empty
• Some controls don't have a 'what's new' or 'changes' section
• Some controls are missing from the 'Controls' section altogether - e.g. RadButton,RadMenu,RadDatePicker

Getting fatal error when I attempt to run the WPF Examples executable. Here is the message:
"Telerik.Windows.Examples has encountered a problem and needs to close...."

Dialog appears to send error report to Microsoft.

Any ideas about how I can correct the problem?

HI,
I'm getting an application error whenever I'm doing a mouse wheel scrolling on an empty grid.
Some details:

Hi,

I tried to show mm/yyyy on gridview with the code

CultureInfo

 

cultureInfo = new CultureInfo("en-US");

 

 

DateTimeFormatInfo dateInfo = new DateTimeFormatInfo();

 

dateInfo.ShortDatePattern =

"MM/yyyy";

 

cultureInfo.DateTimeFormat = dateInfo;

 

Style datePickerStyle = new Style(typeof(RadDatePicker));

 

datePickerStyle.Setters.Add(

new Setter(RadDatePicker.CultureProperty, cultureInfo));

 

datePickerEditorSettings.CellEditStyle = datePickerStyle;

 

 

 

((

GridViewDataColumn)this.radGridViewData.Columns[1]).EditorSettings = datePickerEditorSettings;

It crashes, but if I change MM/yyyy to MM/dd/yyyy, the cells shows MM/dd/yyyy 12:00 AM.

Thanks so much for any help.

 

Ok… I want to play with the Q3 beta because it has fixes for significant bugs in Q2 and support suggested I do so. So, I uninstall Q2 and put in Q3. Immediately, my project breaks because the namespaces and references have been altered. I have some comments and maybe you guys can supply some help.

• Is there a simple, clear document discussing how to upgrade a project from Q2 to Q3? Actually, I had really hoped given the price there would be a tool - alas, it is not to be :)
• The beta documentation lacks any discussion of how to install the controls to the toolbox. While it looks like the installer mad a valiant attempt to do so the toolbox is still littered with icons we don't need there and it is really cluttered. As a bonus point, the controls were added to the 2010 toolbox, but with similar problems.
• While we can drag / drop many controls from the toolbox onto the design surface but the RadGrid isn't one of them. For some reason what I am sure is one of the most used controls of the bunch is the one thats broken :)
• Trying to fill in the holes from the demo source code isn't much help as it looks like the DLL names and namespaces have changed.
• The demo source code included does not build, at least not in VS2008 under Win7 x64

So here are my hopes...

• That someone has a clear, concise guide on what references and so on need to change for goign Q2 -> Q3
• Some source code using the CURRENTLY shipping beta that actually builds and has a grid on it
• Word that the documentation and toolbox issues will be resovled before this ships

 

Thanks! I really love these controls and I just keep asking for more, I know :)

Hi,

For ListView, I can display an image (check mark) inside a checkbox control. For Telerik Grid, how to do this?

Thanks,
