Change color add button

Hello, Serg,

Note that the "Add" button that is displayed like a plus icon is indeed represented by text. In order to change its color, you should change the ForeColor property of the NewItem button. You can access it as shown below:

this.radTabbedFormControl1.TabbedFormControlTabsElement.NewItem.ForeColor = Color.Red;

I hope this helps. Should you have other questions I will be glad to help.

Hi, Serg,

NewItemClicked event is raised when the new tab button is clicked. It offers the standard EventArgs that represents the base class for classes that contain event data. The sender is LightVisualButtonElement that represents the button with the plus icon.

private void TabbedFormControlTabsElement_NewItemClicked(object sender, EventArgs e)
{
    LightVisualButtonElement newItemButton = sender as LightVisualButtonElement;
    newItemButton.ForeColor = Color.Red;
}

Note, RadTabbedForm offers TabAdding/TabAdded events. TabAdding event is raised when a new tab is about to be added to the control and allows it to be canceled. TabAdded is raised when a new tab has been successfully added to the control. Feel free to use them if they are suitable for your scenario. More information you can find here: https://docs.telerik.com/devtools/winforms/controls/forms-and-dialogs/tabbedform/properties-methods-events

If you are experiencing further difficulties it would be greatly appreciated if you can provide more information about which is the exact goal that you are trying to achieve. Thus, we would be able to think of an accurate solution to your problem.

Let me know if you need further assistance.
