I'm using RadControls for WinForms 2008.3 1204.

Assume the following: I have a DateTimePicker and set the MinDate and MaxDate properties.

1. Is it possible to show the "invalid dates", means all dates not between MinDate and MaxDate, in the calendar popup with a certain format, for example strike out or red?

2. Is it possible to prevent the closing of the calendar popup, if no valid date has been selected? Although I can listen to the DateTimePicker's Closing event I don't see how to determine which date has been selected in the calendar popup.

3. If I don't prevent closing the popup (like at the moment) and the user did select an invalid date which has not been applied to the DateTimePicker, the date even stays selected in the calendar popup if I re-open it. Let's say the DateTimePicker's MinDate is set to 2009/01/10. I open the calendar popup and select 2009/01/01. The value will not be applied when the popup closes. But when I re-open it, 2009/01/01 is still shown as selected.

Any helpful hints?

I dragged a new WinForms RadCalendar control onto a WinForms 2008 form.

Selecting the control and viewing its properties in the Visual Studio Properties pane, I set the control's NavigationNextImage and NavigationPrevImage properties to .bmp resources.

The images I assigned show in the designer.

When I run the application the images do not show.  All that shows is the < and > text.

Is setting the images all I need to do to have the images show in runtime or have I missed something?

Thank you,

Hi all

I am evaluating Telerik wincontrols and have this problem...

I have an embedded theme (MyTheme.xml) resource in my own Class Library (MyDll.dll),
The "MyTheme.xml" is set as an embedded resource and I refrence it in my main program.

I try to load the resource from my main VB program (MyProgram) but I cannot get the theme to load.

I am able to load a LOCAL theme resource from inside my main program (MyProgram) using the following

"ThemeResolutionService.RegisterThemeFromStorage(storageType.Resource,

"MyProgram.MyTheme.xml")"

 

 

But when I try to get the theme from my DLL this does NOT work ?
"ThemeResolutionService.RegisterThemeFromStorage(storageType.Resource, "MyDll.MyTheme.xml")"


I have exhausted all the examples on the help & support website and I ned help with this

If you know the answer please reply !.

I want to start off by apologizing for my many posts recently.  A project that was dead for about a year has become a top priority so I have to learn a lot and real fast.  Thank you for everyones help.

My current situation is kind of tricky.  I have a grid view that has many users with State and City columns.  I'm dynamically creating these columns on load of the form.  I'm pointing to all the right field names.  My problem is that I need to be able to populate my city combobox based on my state combobox.  So the user has Florida as State and Orlando as city when the user goes to change the city the drop down should have the rest of the florida cities.  If he changes the state the city combo should populate with all those cities.  I need just the combobox within the current rows datasource to change not every combobox in that column.  Is this possible?
I have a table with StateId, StateName and another table with CityId, CityName.

Anything to lead me in the right direction would be greatly appreciated.

Thanks in advance for any help

I have a RadCalendar which I dynamically change the SpecialDays whenever  the month view changes to add a series of custom controls to that month.  Each day in the month gets the custom control inserted whenever the month changes. The performance isn't great but it is acceptable except when I navigate to the month containing the FocusedDate when the adding of the custom controls takes close to 5 seconds to insert and draw the controls.  Is there anything I can do to speed up the rendering of the FocusedDate month?

Incidentally, if I change months by clicking the navigation button the specialday controls populate for the following month fairly quickly.  If I try to navigate to the next month by pressing the arrow key I get the same very slow update as navigating to the FocusedDate month...

Any solutions?

We build rather complicated applications that need to be deployed to remote users. We're not especially fond of (or experienced with) browser based app dev, and would prefer to use a technology that has a richer interface and good wysiwyg design tools. Long term I may pick up silverlight and ria services, but it's not obvious that they're ready for the kind of cut to the chase development that I prefer.

I know some developers use winforms deployed via clickonce which would be fine for us. But one aspect I've had a hard time getting a clear picture of is how the client winforms app would interact with the database on the remost server. Does anyone here have exposure to that? It's not an approach that really took off, but was promoted briefly by Microsoft in the .Net 2.0 period. Data access technologies have evolved a lot since then and I am not sure what would be regarded as the best current practices. I wish Microsoft had something like RIA Services for winforms. Basic crud functionality is what is needed; there are other aspects like local caching and retry routines that come into play. I don't want to write all of that and so I am hoping to fine a framework or something like that to work with.

Does anyone here have recommondations to make re basic technologies to use, or frameworks that may exist that expidite this approach? I don't think the Telerik OpenAccess ORM deals specifially with actual connectivity - it's just an ORM, right?

I hop it's ok that I'm going to post this query to both winforms and the OpenAccess ORM forms.

Hello,

Hello,

since we have major performance problems with WinForms (esp. RibbonBar takes more than 10 seconds to load),
we tried to improve performance by precompiling the control with ngen.
This failed with the following message (Windows 7 x64):

Any idea, that is causing this error ?

Dear everybody,

I have got a gridview in my winform applicaton. When I minimize my form or suppress it the value/status of the scrollbar gets lost. I then need to scroll back from the top.

Is there any solution for it or property I need to set?
