I just wanted to see if anyone had suggestions for the best way to manage 24 charts on a single form that need to have their data refreshed every 30 seconds. I've done this as a web solution for the last couple of years, but recent development on the software we use to populate the database has made it so that they want all of the charting brought into the software itself and shutdown the website.
With the web solution we ran into fairly frequent issues of having things time out or error because of too many calls to the server, or whatever the problem of the month happened to be. So I wanted to post this to get suggestions from anyone else who has done something similar with WinForms.
The charts will have anywhere from 1 to 30 data points, averaging somewhere around 10-12, so I won't be sending a ton of information out there all the time, but I want to make sure that I can maintain the performance of the web version while hopefully avoiding some of the pitfalls that I might not be aware of since this is the first time I will be using the WinForm controls.

What is the difference between these 2 beasts?
I am having a truly miserable time trying to add a radLabelElement (autosized) followed by a radWaitingBarElement in a radStatusStrip.
I note that using the designer, I can add a radWaitingBarElement to the radStatusStrip, but not a radWaitingBar.
These controls are supposedly updated before and after a backgroundworker completes its job. However, they seem to step on each others' toes, so the radlabelElement's text does not get properly updated, even though the code updates it before starting the background worker. I've tried rolling my own by hosting both a radWaitingBar and a radWaitingBarElement in a radLabelElement and a radHostItem added to the radStatusStrips Items.
None of these things actually works.
Ideas?

Hi Telerik Team,
I use the Telerik release 2012 Q3 2012 (version 2012.3.1017).
I created a radLabel in the design-mode, set the autosize to false in the property window and resize it.
When I debug my application, I see the attribute autosize is true.
The autosite information is in the ressource-file, but i cannot edit it by the property window.
What I have to do to edit this attribute by the property window?
I look forward to your answer.
Best regards.
Frank

Is there a way to use a multicolumn combo box editor in the PropertyGrid?
I've tried creating my own custom editor inheriting from the RadMultiColumnComboBoxElement, but I can't seem to get it working correctly.
Thanks

Dear Telerik!
I have a problem with RadSplitButton in RadControls for WinForms.
I have one or more RadRibbonBarGroup within some buttons and for this reason my form isn’t narrow enough, the RadSplitButton (which is in the RadRibbonBarGroup) has an error.
So when I open down the RadRibbonBarGroup than click on an item (the item open a new form) on RadSplitButton, the RadSplitButton remains open.
I attach some screenshot to show you my problem.
Is there any solution for this?
Thanks in advice!

I would like to be able to use the expression editor as a stand-alone component. I've been playing with both the WinForms and WPF versions.
I do realize the WinForms version doesn't directly support standalone operation, so what I've done is created a RadGridView and made it invisible. I add some columns programmatically, and enable expression editing on the first one (only).
Then I have a button which launches the expression editor:
RadExpressionEditorForm.Show(grid1, grid1.Columns[0]);
Which does bring up the expression editor, and I see the other columns I've defined in the "Fields" list.
But the method RadExpressionEditor.Show() method is not modal -- it returns immediately, and I don't see an alternate ShowDialog() signature. Also, the method returns void, so I don't know whether the user pressed Cancel or OK.
I'm guessing that what I should do is handle some event on the grid view to know when the dialog has been dismissed ... but I've tried several, including CellValueChanged() and CellEndEdit(), and they don't ever seem to get called.
What am I doing wrong?!?
