Hello,
I just upgraded from Q1 2010 Sp2 to Q2 2010 SP2, and it seems that the Aggregates property from the DataGroup class is gone. I don't see anything on it in the release notes or on the forum. Am I missing something? Maybe I'm just wrong, I'm new to Telerik, I'm just upgrading a software made by someone who does not work here anymore...

Thank you!

Steve

Change RadTreeView BackColor

Hello,

I have applied the Office2010 theme to my WinForm application by adding the Office2010Theme to the form and setting

ThemeResolutionService.ApplicationThemeName = Properties.Settings.Default.ApplicationThemeName;

Everything works just fine and I am satisfied with the result, except for one small detail. I would like to change the background color of the RadTreeView to white instead of the default gray-ish. Setting the BackColor property of the RadTreeView control does not do the trick, so is there any other way I can do it (in code or otherwise)?

Best regards
Linus

Event on user entry validation

Hi,

I'm working in VB with 2010Q3 terik winform.

I have a RadDropDownList with some predefined items.
I wan't to give possibilty for users to enter their values if needed.

But I don't find how to trap when they have finished to enter the text.

The event IndexChanges fire only when they choose a predefined value
The event TextChange fire every time user press a key
The event SelectedValueChanged never fire !

I need to update my form when user choose a item from existing value or when user have finished to entered his own value.

Thanks for your help.

Customizing the Timeline View

I am looking to use the Timeline View with Resource Grouping to show a timeline of about three months, (from 2-weeks-ago to 2-months-from-now), all visible at once, and allow for scrolling beyond those visible limits.

It seems that, by default, the timeline shows only 7 days ahead of the StartDate which I have set to DateTime.Now.AddDays(-14) to set the first visible date back two weeks from today. I would like to be able to set the number of visible days to ±70, (and eventually use a radtrackBar to dynamically change the number of visible days).

Aside from that, how would I set the width of the day 'columns' in the TimeLine? Most of the appointments I will be adding to the scheduler will be several days, even weeks in duration and I will only require a month heading and a numerical day label.

Thanks,
Adam

CellBeginEdit e.rowindex is incorrect

I need to interrogate a cell on the row being edited to determine if editing is allowed. The cell I'm trying to retrieve is a hidden column, not the one the user is trying to edit. When I look at the value of e.rowindex it doesn't match the row being edited. The grid is a hierarchy view. The value of e.rowindex seems to be associated with the rows being displayed at that hierarchy level.

How can I get the row being edited?

I switched over to the latest release and this fixed the problem.
