Just wondering if the DateTimePicker can resolve xml date time ie: yyyy-mm-ddThh:mm:sszzzzzz.

I am trying to get/set the value to and from XML but cannot see how I can achieve this with this control. For example, provided it is possible, will it remember when it is UTC or Local.

Custom- and BasicFiltering

Hi!

How can i use custom- and basic filtering combinded ?

There is a customFilterRow example, but it does not contains the basic filter row either.

I have a textBox, and on the textChanged-event i refresh the masterTemplate and the customFiltering-event is fired.
Then i do my filterSearch. Everything works fine, like in the customFiltering-example.

But after that, i want to use the basicGridFilter, but it doesn't work. if i clear the textBox i set the enableCustomFiltering to false,
and then the grid is empty. i only get basic or customFiltering to work, not both.

Thx !

The textBox (customFilter) is used for a search on the whole grid.
The FilterRow should be used to filter each row.

[Solved] Panel Rounded Corners Issue

Hi! I am creating a panel with rounded corners, I followed the documentation here and was able to get that. The problem comes when I wanna change the color of the panel. For instance, I have a gray background on my app, and the panel has a white background. Instead of only seeing the rounded corners on the panel... I am seeing the square corners in white and then a rounded border around the panel. See screenshot. Suggestions on how to hide the square corners?

Thanks!

Disable Key Tips for some controls in Ribbon Bar

Hi there,

is it possible to disable the Key Tips for some specified controls in the RadRibbonBar?

I have placed a RadImageButtonElement and a RadDropDownListElement in the same RadRibbonBarGroup.

I would like to disable the Key Tip feature only for this both controls. All the other controls should be accessible by the Key Tip.

I have set the Property -> radRibbonBar1.EnableKeyMap = true; and for the other controls in the RibbionBar I assigned the KeyTip too.

At the moment the RadImageButtonElement and RadDropDownListElement get a numeric automatic key tip.

I use RadControls for WinForms Q3 2011 SP1.

If anyone has any ideas I would appreciate

Thanks in advance

Unsubscribing to static events on forms where DocumentWindowis parent

I have a few global static events that some of my forms subscribe to. The subscription happens in the Form.Load event of each form. Those forms are added to a DocumentWindow then to the DockManager. The subscription is great, everybody's listening fine. Now when I close a DocumentWindow, the forms OnClosing events doesn't happen thus not unsubscribing to the static event I had wired. So now when another form (document window) fires the static event I get an exception from the closed form where the static handler is trying to work but the form doesn't exists anymore.

Any ideas on how to unsubscribe to static events on forms that are children to DocumentWindows once closed?

Thanks,
Byrd

cross-thread exception in page view

my application uses BackgroundWorker to initialize user controls and load data models for the control to keep the user interface responsive. i have a custom control which uses page view to show different custom user controls. i load data for the control and instantiate the control in a background thread. after initializations the data model and the control is added to a global list of controls. the main ui then shows the control in a tab document. now when i try to add it to the tab the page view page object throws an exception mentioning cross thread access. i have checked for cross thread access before adding the control to the tab strip. it only happens if i use a page view control inside the my custom user control. instead if i use a tab strip than page view in my custom control it works fine.

how can i avoid this exception?
