Hi, Mark,

I have tested with R3 2015 version as well and the functionality at design time is similar for RadCheckBox. Even though the Checked property is not explicitly available under ApplicationSettings in VS Properties section,  I would highly encourage you to use the previously suggested solution with adding the simple data binding programmatically while this feature is considered in the upcoming releases.

As to the question about the converter, please have in mind that the WinForms converter was introduced in R2 2016 (version 2016.2.503). This tool allows you to convert the standard .NET Windows Forms controls for all projects in a particular solution to their equivalent in Telerik UI for WinForms. It aims to speed up the conversion process and save time when such projects are modernized. After the conversion process is completed, you should check if all existing functionality is working as before.

I suppose that if initially the project contained the standard MS CheckBox and the binding was performed at design time, similar code was serialized in the Designer.cs file:

Me.CheckBox1.DataBindings.Add(New System.Windows.Forms.Binding("Checked", Global._1603312CheckBoxDataBinding.My.MySettings.Default, "IsFiltered", True, System.Windows.Forms.DataSourceUpdateMode.OnPropertyChanged))
       

After running the converter tool, the CheckBox is converted to RadCheckBox and the previously serialized data remained. That is why the functionality continued working. However, if a new RadCheckBox is added to the form, the design time experience wouldn't allow you to setup the binding this way.

Hi, Mark,

Thank you for the provided additional details. I have reversed to an older version back to 2010 but I was unable to observe the functionality that RadCheckBox used to have according to your previous reply. Could you please specify which is the old Telerik version in which it was possible to bind the IsChecked property to an application setting at design time? Thus, we would be able to revise in a deeper manner what changes have been introduced during the years.

Thank you in advance. I am looking forward to your reply.

Hello, Mark,

Thank you for reporting this.

I confirm that this is a reasonable request and we will try to improve the design time data binding options for RadCheckBox. Make sure that you follow the item in order to get notified once any status changes occur.
