I have a .Net6 winform app and was trying to bind sqlite to radgridview.

Has anyone bound the radGridView to a SQLite db via entityframework?  If so what is the best way to go about it?  I have not yet been able to find anything on it.

thanks!

Hi,

I would like to know how to get the size of the cartesian area (red square above).

I tried with radspy to get the right element, but there is no size set, everything is "0,0", any idea?

Thanks in advance

Hi,

I installed the Telerik WinForms at the first time and developed something with the RadGridView and more. After this, I want to use the Export Function, to export the RadGridView to Excel. But it doesn't know "SpreadExportRenderer" and I search for the problem.

I looked at my references in my project and the .dll called "Trial Version". I looked for the correct assemblies/library and found some Infos that the Assemblies for .NET 4.7 is in the folder "Bin45". But in my Folder "C:\Program Files (x86)\Progress\Telerik UI for WinForms R3 2023" I only found "Bin40", "Bin48", "Bin60", "Bin70", "BinNetCore", "Examples", "LicenseAgreements" and "VSExtensions". But no Bin45, I needed.

In this case, I try to change the as Trial marked .dlls with the .dll from the "Bin48" folder, but I get errors.

I am a little bit confused. Maybe someone can help me :)

Hi, I'm using a RadPdfViewer to show a document, and a RadPdfViewerNavigator associated with him.

I have 2 questions:

1) I've noticed that even if the pdf document is not loaded in the RadPdfViewer control, all buttons in the RadPdfViewerNavigator are enbaled, then the user can click on some button and I tthink this is not correct (further, the application can crash if he clicks for example, on the rotate button). Is there a way to tells that to the RadPdfViewerNavigator to enable/disable buttons in base of loaded document, or I need to do it programmatically?
2) The print preview form is very well and powerful, but I've noticed that it is very slow to move from a page to another... It can be a problem on my own, or it is by design?

Thank you for any assistance.

Is it possible to mimic an <hr> tag in the Html markup functionality?  Trying to create dividers in the RadLabel control.  Has anyone implemented something similar?

Thanks!

I'm using RadSpreadsheet with the ribbon bar to display a generated Excel workbook.  Users want to save the workbook via the Save ribbon button, but they want a default filename in the save dialog (not "book1.xlsx").  I can't figure out how to get there from current documentation and other forum questions.  Please advise.  Hoping I can access it without overriding the whole framework that already does most of the work for me.

Hi,

When form loads scroll bar missing as well as summary also missing but when i resize the form it appear and work appropriately.
I believe this is some visual glitch. Please provide me some solution for this.

Hi,

I'm looking into the viability of using the WinForms RadSyntaxEditor for a small project.

I think I've come across a bug when it comes to DPI scaling.

The component itself seems to work fine with DPI scaling except for the search/find functionality. When you search for some text and click to go to the first instance it finds, the actual text is off screen, though it is highlighted correctly (when you scroll down you can see it highlighted).

If I set the CaretPosition manually to a line further in the document, it also displays correctly so it seems to be specifically limited to the  built-in Search/Find panel.

This is easy to replicate by changing Windows display scale to anything other than 100%.
