I have a form, with a single control - ComboListBox. I bind that control to a datasource using datasource, displaymember, and valuemember. I display that form. In either the load event or instance of the form, I can have code to SetSelected to true for any two items. If that form is part of an application where the mainform is an MDI form, that SetSelected does not work. If that form is part of an app where the main is NOT an mdi form, it works fine. Exact code both projects. Weeeeeeird. Tim

Hi Tim, Which version of Essential Tools are you currently using? Also, we do not have a ComboListBox control so are you using the ComboBoxExt control along with the Windows Forms ListBox? Can you update us with details so that we can try to set up a sample and take a look at this issue? Regards Arun

Your project references a CombBoxBase which i do not have. What is the namespace for this object? Syncfusion.Windows.Forms.Tools.ComboBoxBase does not exist in my environment.

Hi Tim, Please replace all instances of ComboBoxBase with ComboBoxExt and that should take care of this error. ComboBoxExt control was renamed as ComboBoxBase according to the Essential Suite 2.0 naming conventions. Please let me know if you need any othe information. Regards, Guru Patwal Syncfusion, Inc.
