Hello Ray Wang,

Thank you for the questions.

You can set header row height by using TableHeaderHeight property:

this.radGridView1.GridElement.TableHeaderHeight = 100;

You can use custom images for the hierarchy expand/collapse cell element through SignImage property. Please consider the following code:

void radGridView1_ViewCellFormatting(object sender, CellFormattingEventArgs e)
{
    GridGroupExpanderCellElement element = e.CellElement as  GridGroupExpanderCellElement;
    if (element != null)
    {
        element.SignStyle = GridGroupExpanderCellElement.SignStyles.Image;
        if (element.RowInfo.IsExpanded)
            element.SignImage = _minusSign;
        else
            element.SignImage = _plusSign;
    }
}

Also you can achieve the same result by a custom theme. For additional information about using and applying custom themes please refer to our documentation. 

Do not hesitate to contact me again if you have any other questions.
