Hi, the new feauture Merge Cells is very nice but the alignment is only at the center.

Can I align the merged cells in the same mode of the column?

Thanks, Fabrizio

After more than 10 years this is STILL a Bug. 

https://feedback.telerik.com/winforms/1369181-fix-radgroupbox-with-collapsed-header-does-not-fill-the-entire-content-if-there-is-a-docked-child-control-inside-the-groupbox

The groupbox header does not collapse when I put a table layout panel inside of it.

Is this product (Telerik for winforms) still being supported? Or should I be looking elsewhere for a different controls toolkit solution for my company?

Any anchor setting works, except for right + left, then the controls start to behave weird. 

this.radMultiColumnComboBox4.Anchor = AnchorStyles.Left | AnchorStyles.Right;
this.radTextBoxControl2.Anchor = AnchorStyles.Left | AnchorStyles.Right;
this.radSpinEditor4.Anchor = AnchorStyles.Left | AnchorStyles.Right;
this.radDropDownList4.Anchor = AnchorStyles.Left | AnchorStyles.Right;

this.radMultiColumnComboBox3.Anchor = AnchorStyles.Left | AnchorStyles.Right;
this.radDropDownList3.Anchor = AnchorStyles.Left | AnchorStyles.Right;
this.radSpinEditor3.Anchor = AnchorStyles.Left | AnchorStyles.Right;
this.radTextBoxControl1.Anchor = AnchorStyles.Left | AnchorStyles.Right;

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.

The annotation line is supposed to be at 05 point but instead it is between 05 and 06.

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+

When a RadValidationRule has the "PropertyName" assigned to a non-existent property, the RadVAlidationProvider.ValidateCore throws a NullReference exception because the property cannot be found via reflection and throws no error handling.

From OpenEdge ABL class, this is the code written into the forms InitializeComponent method.  The "IsValid"  property doesn't actually exist.

        radValidationRule3:AddControl(THIS-OBJECT:myTextBox).         radValidationRule3:Operator = Telerik.WinControls.Data.FilterOperator:IsNotEqualTo.         radValidationRule3:PropertyName = "IsValid".         radValidationRule3:ToolTipText = "Test".         radValidationRule3:Value = TRUE.

While we don't expect the functionality to actually work because the property isn't actually available to .NET, but the NullReferenceException is poorly handled.

I've attached a screenshot of the bit of code from RadValidationProvider.ValidateCore where this occurs.  This is from version 2020.3.1020.20

Here is the thrown stack exception details from visual studio.

System.NullReferenceException
HResult=0x80004003
Message=Object reference not set to an instance of an object.
