My users want a UI that looks like the screen capture below. They want to be able to drag squares from the top frame to the bottom (mutually exclusive) and reorder them within the bottom frame and then save/restore between editing sessions. Do you have a control designed for this?

Thanks

I've been looking at the release notes and i can see that a selection checkbox has been added since we last updated which is great.  I can also see as per the release notes that there is a "New mode for selecting rows only via the selection checkboxes".  Does anyone know how to configure this?

Cheers!

I've just published all my .Net 9 apps using ClickOnce, all of them are now broken !

Using the following Nuget : UI.for.WinForms.AllControls.Net90 version 2025.1.211

They all crash on startup with the following error :

I want to set the selected date of the Calendar, like with the DateTimePicker.

The SelectedDate property, which allegedly has a getter and setter, does not seem to work.

radDateTimePicker1.Value = DateTime.Now.AddDays(-3);  // This works great. The picker displays the date from three days ago.

radCalendar1.SelectedDate = DateTime.Now.AddDays(-3); // This shows today's date.

What am I missing?

TIA!

Hello,  

I'd like the number of characters in the form title to be reduced when I reduce my form.

example with eclipse: (Width form: 1000)

projet_xxxxx - c:/mon_projet/srv/fichier/caracteristique/grid/form_caraterisque.cls - Progress Developper Studio

and after reduction of Form (width form 700)

projet_xxxxx - c:/mon_projet/srv/fichier/caracteristique/grid/form_caraterisque.cls - Progress ...

the title and ...

best regard.

After performing an ExportToImage using the RadBarCodeView, I'd like to delete the image from the harddrive.

But it always says that the file is in use and cannot be deleted.

I tried setting the RadBarCodeView1.value = Nothing (trying to make it release the image file) but that doesn't work either.

Any idea's on how to release that image file?

Hello everyone :)

I've got a new project that includes a RadListView that I have placed on a WinForm with ViewType = IconsView

I'd like to display a thumbnail along with some HTML text - but I'm struggling getting the data I need from the object being formatted.

Here's my VisualItemFormatting method:

myViewElement.Items(0).Tag holds a class that contains the text I'd like to display along with the correct icon size (these are documents of various sizes so I'd like the icons to have the same width/height ratio.

myViewElement.Items(0).Tag is clearly WRONG...it's there and not Nothing but it's the 0 index of all Items in the RadListView and it's in my code as a place holder so I could build the rest of the UI class.

Does anyone know how I can get the index of the ListViewItem that's being "formatted" by VisualItemFormatting?  Of not the index from the RadListView's Item collection, maybe the actual ListViewItem object itself?

Any help would be appreciated.

Thank
