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?

Hi,

We are using Radgridview with CheckBox and also we have added the CheckAll and UnCheckAll button. We have finished this CheckAll and UnCheckAll functionalities using looping with grid.rows.count, but when we are filter the row it shows the total rows count and also getting the exception like 'Index 145 is either negative or above rows count.'. Refer the below code and kindly let me know how we have to solve this issue.

CheckAll:

for

 

(int i = 0; i < radGrid.Rows.Count; i++)

 

 

 {

    radGrid.Rows[i].Cells[

"-"].Value = Boolean.TrueString;

 

 

     item = radGrid.Rows[i].DataBoundItem;

 

    if (!this.selectedRows.Contains(item))

 

 

 

        this.selectedRows.Add(item);

 

 

 }

 

UnCheckAll:

this

 

.selectedRows.Clear();

 

 

 

for (int i = 0; i < radGrid.Rows.Count; i++)

 

 

 {

         radGrid.Rows[i].Cells[

"-"].Value = Boolean.FalseString;

 

 

 }

Hello,

I need to slightly adjust the default theme and save it in a new theme.
working with the latest release 2009 q3 1203

Took the following steps:

downloaded the sourcode and created modified the RadControlsTheme.ControlDefault class library.
Made the modifications and they seem to work ( only 1 control is modified so far).
The problem is that the Control default theme looks different then before (older). 

Is the included theme in the download the latest version?
Where can i get the correct version of the class library officeblue 2007 theme.

Kind regards,

Tim
