Hi,
I added a screen with RadSpreadsheet on it. When I open that screen from the parent screen, the DPI (scale) of the whole application changes.
Please find the source in the attachment.
Hi All.
Could you please add or let me know locators for "RadChat" window for Automation purpose. I am unable to find locators on the below area.
In.NET8 Microsoft has released databinding improvements: What's new in Windows Forms .NET 8 - Windows Forms .NET | Microsoft Learn. Add Command Binding and DataContext Support in .NET 8+
Documentation about High-DPI mechanisms available on the website is very outdated and mostly does not consider the changes and improvements that Microsoft made with .net 7.0 and 8.0.
What's needed is thorough documentation about Telerik's behavior in comparison with the different situations on .net Framework 4.9 and the major .net Versions 6.0, 7.0, and 8.0.
Kind regards
Erwin
Top Level Exception
Type: System.OverflowException
Message: Arithmetic operation resulted in an overflow.
Source: TelerikCommon
Stack Trace: at Telerik.WinControls.NativeMethods.GetMonitorDpi(Screen screen, DpiType dpiType)
at Telerik.WinControls.VisualElement.GetScaledFont(Single scale, Font fontToScale)
at Telerik.WinControls.UI.LightVisualElement.CreateTextParams()
Repro-steps:
- Create a RadGridView
- MultiSelect = true
- SelectionMode = CellSelect
- Fill it with lots of cells (in my case: 7 columns, 8544 rows)
- Press CTRL-A
- Press Delete
Expected behavior:
- All rows are gone
Observed behavior:
- 50/50 change that some rows remain.
I traced the problem back to the method GridViewSleectedCellsCollection.IsSelected / GetHashCodeString.
internal bool IsSelected(GridViewRowInfo row, GridViewColumn column) => row != null && column is GridViewDataColumn && this.hashtable.Contains((object) this.GetHashCodeString(row, column));When a cell is selected with GridViewCellInfo.IsSelected = true, it checks if it has already been selected. It does so by calling GridViewSleectedCellsCollection.IsSelected. which checks if a HasCodeString is already in a hashtable. But, when another selected cell has the same HasCodeString, the result is (incorrectly) true, which will result in not added it to the collection of selected cells.
I guess that is can be easily fixed by changing:
private string GetHashCodeString(GridViewRowInfo row, GridViewColumn column)
{
int hashCode = row.GetHashCode();
string str1 = hashCode.ToString();
hashCode = column.GetHashCode();
string str2 = hashCode.ToString();
return str1 + str2;
}to:
private string GetHashCodeString(GridViewRowInfo row, GridViewColumn column)
{
int hashCode = row.GetHashCode();
string str1 = hashCode.ToString();
hashCode = column.GetHashCode();
string str2 = hashCode.ToString();
return str1 + "_" + str2;
}Since hashcodes 1 + 23 will result in the same string as hashcodes 12 + 3.
Making this change will reduce the problem significantly, but not entirely since hashCodes will never be unique.
Apply the Office2010Silver theme to your application since it has a good border indication for the focus in RadSpinEditor.
Please run the attached project and click in the RadSpinEditor that is not in the RadPopupContainer. You will notice that when you move the mouse away that the border is highlighted in yellow showing that the control has complete focus. Now, click in the RadSpinEditor that is in the RadPopupContainer and move your mouse away. You will notice that the border is not highlighted in yellow indicating that it does not have focus. You can also see that it does not fire the GotFocus event. If you click closer to the border out of the "TextBox" area, the control border will stay yellow showing complete focus and fire off the GotFocus event. However, in this case, the caret is not displayed.
Workaround: handle the GotFocus/LostFocus events for the SpinElement.TextBoxItem and apply the desired border for indicating the focus.
UI for WinForms - Latest version.
RadRibbonBarBackstageView - Edit UI Elements
RootRadElement.BackstageViewElement.BackstageItemsPanelElement.BackgroundImage
Click the … button and select your image.
To REMOVE this image you SHOULD be able to do the following:
click on the property BackgroundImage which should highlight the image-string completely.
click delete.
done.
What you HAVE to do is this:
click on the property BackgroundImage.
click delete.
BEFORE YOU LEAVE THIS PROPERTY you have to click the … box
Once the box opens you have to click "Cancel"
Right below this property is BackgroundImageLayout - set to "Center"
There's a dropdown arrow presumably to allow you to change the layout but nothing happens when you click it.
*Missing Property?*
Whatever image you place in this control it gets stretched and there doesn't appear to be any way to avoid this:
place an image.
run the winforms ap.
set the main form in normal mode (not maximized) and resize the height.
Your image will stretch, shrink...this is not a UI property that should be presumed. We should be able to set None, Tile, Center, Stretch or Zoom.
Still *LOVE* your products :)
Kindest regards,

## Summary:
During security testing of the email change functionality on the Telerik website, it was discovered that the application can be vulnerable to an account takeover attack. The vulnerability allows an attacker to change the email address associated with an account to their own email address, effectively taking over the victim's account.
## Vulnerability Details:
- **Functionality Description:**
- The Telerik website provides a functionality for users to request a change in their email address.
- This functionality consists of two sections: current email and new email.
- The current email is not accessible from the user interface, while the new email can be inputted by the user.
- After inputting the new email and clicking the "Change Email" button, the user's request is processed.
- **Attack Scenario:**
1. **Attacker Inputs Their Email:** The attacker inputs their own email address in the new email section.
2. **Intercepting the Request:** Using interception tools, the attacker intercepts the request before it is sent to the server.
3. **Modifying the Request:** The attacker modifies the request to replace their own email address with the victim's email address in the current email section.
4. **Consent Form Manipulation:** Additionally, the attacker can manipulate the consent form associated with the email change request to gain access to the victim's account without their consent.
5. **Changing the Email Address:** The modified request is forwarded to the server, resulting in the victim's email address being changed to the attacker's email address.
## Impact:
- **Account Takeover:** The vulnerability allows an attacker to take over the victim's account by changing the email address associated with it.
- **Data Access:** Once the attacker gains access to the victim's account, they may have unauthorized access to sensitive data and functionalities associated with the account.
## Mitigation Recommendations:
- **Input Validation:** Implement strict input validation to ensure that only legitimate email addresses are accepted in the new email section.
- **Consent Verification:** Require additional verification steps, such as email confirmation or user authentication, before processing email change requests.
- **Session Management:** Implement session management mechanisms to detect and prevent unauthorized access to account settings and functionalities.
- **Security Awareness:** Educate users about the risks of phishing attacks and social engineering tactics used by attackers to gain unauthorized access to accounts.
## Affected URL:
- Email Change Functionality: [https://www.telerik.com/account/support-center/email-change](https://www.telerik.com/account/support-center/email-change)
## Conclusion:
The discovered vulnerability poses a significant security risk to Telerik website users by allowing attackers to take over accounts through manipulation of the email change functionality. It is imperative for the development team to address this vulnerability promptly by implementing appropriate security controls and mitigations to safeguard user accounts from unauthorized access.

Windows Forms on .net 6.0 / 7.0 / 8.0 diverges more and more from .net Framework 4.x.
Please release a version of the Demo Application that is based on the current Microsoft Release.
Hi
It would be cool if the SyntaxEditor automatically changed the default palette if the selected scheme was dark.

Hi,
Please, add a property or method to the RadWebCam control to set video bit rate or quality. Currently is fixed a 4 mbits and it results in very poor image quality at high resolutions.
Please find attached images to see the difference between snapshot and video recording. With fast moving pictures is even worse.
Thanks.
