I'm trying out the scheduler component, and I will need to default to having appointments as multiples of 30 minutes.

The way I think I should be doing this is

    
            SchedulerDayView view = radScheduler1.GetDayView(); 
        
            view.RangeFactor = ScaleRange.HalfHour;

But when I do that, and then try to create appointments, the start and finish time boxes are greyed out and the appointments always end up being all day appointments.

I am using a custom Appointment type and custom EditAppointmentDialog, but everything is working fine for me until I set the RangeFactor.

I'm using 2009 Q2 SP1.

Can anyone give me any hints as to why this would not work?

Thanks,

Marcus.

RadForm NOT a drop-in replacement for a Widows Form ?

excuse the typo in the topic title ...

2009 Q2
When I simply change a Form to inherit from RadForm instead of standard WinForm Form, a lot of things don't work as expected anymore. For example Saving and Restoring Windows Position etc. does not work identically.

Also I have a problems with RadForms that were created with earlier Versions of the Controls. Here, anchored Buttons suddenly do not appear at the right place at runtime. I guess it has something to do with the non-client area drawing / sizing as the child controls seem so be moved upwards about the height of the window title bar.
These issues I cannot reproduce with sample code as it would mean setting up a development machine with older versions.

IDataErrorInfo and INotifyPropertyChanged

Hello Telerik team,

I'd like to know if the grid view (and all RadControls for Winforms in general) supports the abovementioned interfaces for automaticallty notifying validation errors to the end user.
I have a business classes hierarchy implementing these interfaces. I have developed some projects using another control suite. I'm considering migrating one of them using the RadGridView, and automatic support for IDataErrorInfo and INotifyPropertyChanged would be critical requirements to proceed.

Best regards,

Gonzalo

ToolTipTextNeeded bug on Label

I have discovered what I believe to be a bug on the RadLabel control. When you react to the ToolTipTextNeeded event the sender is the Label element and not the label control, this is contrary to the other events, such as the mouse click event which the sender is the Label.

[Solved] Close Button query

I've recently tested the new raddock and the code for pretty much all operations is so much simpler that it really is a complete pleasure to use. However there is one thing that I got an example from off these forums some months ago that for some reason (I assume some simple oversight of mine) I cannot duplicate.

That is to add a close button(or any button) to a tab on the right side of said tab.
I can add the button no problem (with alot less code than before \o/)
- correct size etc but for some reason it always aligns the button left.

I'm quite certain I'm missing something simple but for some reason can't figure it out.

Thanks in advance

new install

I downloaded and installed the new version of all the Telerik controls. I am in a project that I've been working on for awhile and some of my design pages will not load or when I run/test the program, it doesn't work because now some "object references are not set to an instance of an object." When I open a design page, I get errors like this (and I can't see teh design page at all): "No such property registered: IsPressed, Telerik.WinControls.UI.RadButtonItem" or "No such property registered: NumberOfColors, Telerik.WinControls.UI.LightVisualElement" or just "Object reference not set to an instance of an object" Is there something else I need to do besides just installing the new version of the Telerik controls?

Charts databound to Datatable

Hi,
How can I do the following.

I have a radchart set to be a pie chart and I have a datatable with many columns in it. When I set the datasource of the chart to the datatable I get results for every column. What I want to do is get it to create a pie chart on just one column. How do I achieve this?

radChart1.DataSource = Myds; //Is the datatable with many columns

What do I set on radchart to just use one column from that table.

Thanks.

Issue with top caption

I'm running into a problem with the caption of the group has odd alignment when the form loads. I am using the OutlookNavPane style.

I am programmatically expanding and selecting the first group panel group with code like this:

    
            RadPanelBarGroupElement group = pnlMainNav.Items[0] as RadPanelBarGroupElement; 
        
            if (group != null) { 
        
              group.Expanded = true; 
        
              group.Selected = true; 
        
              group.ContentPanel.Controls.Add(new PersonMenuPanel()); 
        
            }

Everything looks fine at first as the caption at the top of the PanelBar is correctly named but it is not centered. Manually clicking the panel group button the text centers. I'm not sure what is causing this, but I'd like it display properly when the form loads.

Has anyone experienced this or have a workaround/fix for this?
