RadMenu DropDown color?

[Sherlock]

Hi
I have four questions:
1. How can I make transparency drop down menu in RadMenu items?
2. How can I make transparency drop down menu header ?
3. how can I change the color of selection of buttons? I mean when mouse moves on buttons, it appears yellow. I need it to be appear green.
4. How to make disappear the drop down header line? I mean if you pay attention to the drop down menu, you can see a vertical band at the left or right side of the drop down menu, depends on right to left setting. I need this band to be disappear like a very simple drop down.
Thanks

Hello Sherlock,

Thank you for contacting Telerik Support.

Please have a look at the following code snippet, demonstrating how to achieve the desired style:

public Form1()
{
    InitializeComponent();

    //#3 change items hover color
    foreach (RadMenuItem item in radMenu1.Items)
    {
        item.MouseEnter += item_MouseEnter;
        item.MouseLeave += item_MouseLeave;
    }

    //#1 transparent RadMenu
    radMenu1.MenuElement.MenuFill.BackColor = Color.Transparent;

    RadDropDownMenuElement ddl = radMenuItem1.DropDown.PopupElement as RadDropDownMenuElement;

    if (ddl != null)
    {
        //#2 transparent drop down menu
        radMenuItem1.DropDown.BackColor = Color.Transparent;
        ddl.Fill.BackColor = Color.Transparent;

        //#4 disable drop down header line
        ddl.LeftColumnElement.Visibility = Telerik.WinControls.ElementVisibility.Collapsed;
    }
}

private void item_MouseLeave(object sender, EventArgs e)
{
    RadMenuItem item = sender as RadMenuItem;
    item.FillPrimitive.BackColor = Color.Transparent;
}

private void item_MouseEnter(object sender, EventArgs e)
{
    RadMenuItem item = sender as RadMenuItem;
    item.FillPrimitive.BackColor = Color.Green;
    item.FillPrimitive.GradientStyle = Telerik.WinControls.GradientStyles.Solid;
    item.BorderPrimitive.Visibility = Telerik.WinControls.ElementVisibility.Collapsed;
}

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

Great help!
Solved :)

But just one question.
As I see your kindfull example, you changed the selection color via handler.
Of course it works, but I need to know isn't there anyway to change this color without using handler of mouse hover?
For example some codes like this:

this.radMenu1.MenuElement.MenuFill.SelectionColor.BackColor = Color.Red;


I believe there is no field name which is "SelectionColor"
But I just curious that if there isn't any options in settings of radMenu? Or any settings in Hiararchy menu?
Thanks.
