How to change font size dynamically?

[NEPProgrammer]

I see this question has been brought up before but the thread was closed. I inherited a website where clients can submit transactions and on the same site we can approve them internally. To make the process easier I've been asked to highlight the Label fields where changes were made. I've also been asked to make the text Bold. The Labels are contained in a Form so the font is ReadOnly. The previous post said you could get around that by creating a new Font. I am still frustrated by Property 'Font' is 'ReadOnly'. Any advice would be appreciated.

Dim boldFont As New Font("Calibri", FontStyle.Bold)
Dim lLabelFirstName As Label = _
FormViewReviewEnrollment.FindControl("LabelFirstName")
lLabelFirstName.BackColor = Color.Yellow
lLabelFirstName.Font = boldFont

I believe you can set the individual properties. .font.bold=true. .font.size=13

Not when it is containted in a <asp:FormView>. I keep getting errors saying that Font is readonly if I try to add code to update it in the VB

        Dim lLabelFirstName As Label = DirectCast(FormView1.FindControl("ClubNameLbl"), Label)
        lLabelFirstName.BackColor = Drawing.Color.Yellow
        lLabelFirstName.Font.Bold = True
 

I had absolutely no problems running this code from a button on an item in the formview.

I don't know what I was doing wrong but I must not have been doing something correctly because it is working now. Thank you so much.
