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 :

Application: MyApp.exe

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

I need to add a RadioButton column to my grid and I adapted the code in this demo to do it:

https://docs.telerik.com/devtools/winforms/knowledge-base/creating-a-radradiobuttoncellelement

The difference is I need a single radio button on each row and they need to be mutually exclusive of one another. This part is now working.

Using some sample credit card data, I have 3 challenges that I can't figure out:

1. How can I start the attached project and set the button for the credit card need selected when the form loads?

2. How can I retrieve the selected credit card id value (if any)?

3. I also seem to have a visual bug whereby when I scroll the grid up and down sometimes the button deselects and sometimes it seems to select a second option.

Could you please examine the attached project and let me know what I'm missing?

Thanks

Carl

Hi All,

I have a requirement to convert the mouse position in thepicture box control to the actual pixel position within the image. This must work when image layout is set to zoom, and handle when the image is zoomed in / out and panned within the control. If the mouse is moved outside of teh image but is still within the picture box then the X/Y coordinates would be set to -1, -1.

Is there any helper functions or sample code I can use to achieve this?I have a simple solution but this does not handle when the image is zoomed / panned.

Many thanks
Toby
