Hi Eric,
Thank you for your interest in Syncfusion Products.
It is not possible to remove the "Customize Quick Access Tool Bar" button in a RibbonControlAdv. But
we can disable the Customize option in the dropdown. This can be done by the below given coding.
private void ribbonControlAdv1_BeforeCustomizeDropDownPopup(object sender,
DropDownEventArgs e)
{
e.DropDown.Items[0].Enabled = false;
}
[Note : However, Customize dialog can be opened by right clicking the RibbonControlAdv.]
Please refer to the attached smaple for more details.
