Disable animations on RadComboBox and other controls

[Björn]

Hi,

I need to disable expand/collapse animations on RadComboBoxes, GridViewFiltering popups etc, because it disturbs the end user.

Using of telerik:AnimationManager.IsAnimationEnabled="False" (on a single control) or AnimationManager.IsGlobalAnimationEnabled = false (globally) have no effect.

The application uses implicit themes.

Thank you for any help.

Hello,

The animation of the ComboBox comes from the Microsoft's Popup control. So, in order to disable it, you need to find it and set its PopupAnimation property to None, for example:

this.myComboBox.Loaded += (s, e) =>
            {
                var popup = this.myComboBox.Template.FindName("PART_Popup", this.myComboBox) as System.Windows.Controls.Primitives.Popup;

                popup.PopupAnimation = System.Windows.Controls.Primitives.PopupAnimation.None;
            };
