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

Rajkannan

Hi, Raj,

I have tested the BackColor in the described versions and the screenshots below illustrate how was observed on my end:

2013.3.1127:

2023.2.606 (latest):

Ten years versions gap is a serious upgrade. That is why I would recommend you to have a look at the release history and pay attention to the breaking changes section and what is listed in it. Thus, you will get familiar with the potential changes that may come after upgrading from one version or another. 

In Q1 2016 SP1 (version 2016.1.216) we introduced some improvements of the Telerik Presentation Framework and now setting the RadTextBox.BackColor will apply the desired color without the necessity to specify the color for the inner elements:

I tested with the Desert theme since I suppose this is the applied theme according to the screenshots on your initial post. If there is a specific setup and custom settings applied to the form and its controls that may affect the back color, it would be greatly appreciated if you share them with us.
