I add a new RadButtonElement in RadRibbonBarGroup and Set the image of RadButtonElement . When the cursor over the button, the button's color(?) changes.

Like the attach images.

But I wrote following code， it do not have the same change when  the cursor over the button.

So I want ask which property can achieve that。

.

 

 

Sorry, The code:

 RadButtonElement btnChangePassword = new RadButtonElement();
                btnChangePassword.ButtonFillElement.BackColor = Color.Transparent;
                btnChangePassword.ButtonFillElement.GradientStyle = Telerik.WinControls.GradientStyles.Solid;
                btnChangePassword.Class = "RibbonBarButtonElement";
                btnChangePassword.Click += btnChangePassword_Click;
                btnChangePassword.Image = Properties.Resources.Config_Default;
                btnChangePassword.Margin = new Padding(0, 20, -20, 0);
                btnChangePassword.TextImageRelation = TextImageRelation.ImageAboveText;
                btnChangePassword.BorderElement.Visibility = ElementVisibility.Hidden;
                this.radRibbonBarMain.RibbonBarElement.ButtonsContainer.Children.Insert(0, btnChangePassword);​

Hello Baboi,

Thank you for writing.

The local value, applied to the BackColor property, overrides the applied styles coming from the theme. That is why the applied color for the hover state is lost. Since Q3 2015 we have introduced a new API for changing the style for a specific element state without losing the applied style for the rest of the states. Please refer to the Override Theme Settings at Run Time help article which demonstrates how to change the BackColor without losing the hover style.

I hope this information helps. Should you have further questions I would be glad to help.
Regards,
Dess
