Visual Studio 2022 stopped responding for xx seconds.

I've had this nagging error for the last few months with Visual Studio 2022.

Visual Studio 2022 stopped responding for 88 seconds. Disabling the extension Progress Telerik UI for Winforms Extension 2202.3.921.3.

The seconds shown are grossly underreported and exceed 180 seconds. I disabled it through Extensions>Manage Extensions. The freezing has stopped.

VS2019 is not exhibiting this behavior.

Microsoft Visual Studio Enterprise 2022
Version 17.4.0 Preview 2.1
VisualStudio.17.Preview/17.4.0-pre.2.1+32916.344
Microsoft .NET Framework
Version 4.8.04084

Before I attempt to go down this road, can the RadListControl (or any other Telerik control) do the following:

We need text on the left and 2 images on the right both of which can be clicked to fire separate events.

Thanks

Using a Callout as a Tooltip with an Embedded Label TextBox

I have a textbox with an embedded label and use a callout like a tooltip. I saw your code from https://www.telerik.com/forums/using-callout-as-a-tooltip.

The process works fine when using a plain textbox but clicking in the eltextbox to select becomes an issue because the focused control keeps changing between the embedded label and the callout. Is there a way to implement these two controls together? Constant clicking in the ELTextbox will eventually get it selected.

Attached is a sample project.

Thanks,

_Dave

Keytips are not working for Radpageviewpage

Hi Team,

I have tried setting the keytips for radpageviewpage using the property,

radpageviewpage.item.keytip="C"

But while running the application, I don't see any keytips enabled after pressing on Alt key. Only tooltips (letters are underlined) are working to access the pages by holding the Alt key + Letter that has underline.

Here I am attaching my sample code, please find attachment.

Hi Team,

We are using RadTextBox the version is Telerik.WinControls.UI.dll -> 2023.1.314.40. And setting the backcolor is 'System.Drawing.SystemColors.Control' but its showing screen transparent color(gray- this is not correct).

Example code block: Its applied > 1000 places in our project.

this.txtTagNo.BackColor = System.Drawing.SystemColors.Control;

We are planning to migrate 2023.1.314.40 version with visual studio 2022.

Please refer the attached screenshot. Could you please help on this issue?

Note: Its working fine in Telerik.WinControls.UI.dll -> 2013.3.1127.40 with Visual Studio 2010

Thanks
