Answer 1

You'll need to handle the DrawItem event of the TabControl to manually draw the caption. Note: DrawMode of affected control should be set to TabDrawMode.OwnerDrawFixed.

Here is a sample:

private void tabControl1_DrawItem(object sender, DrawItemEventArgs e)
{

    Graphics g = e.Graphics;
    Brush _TextBrush;

    // Get the item from the collection.
    TabPage _TabPage = tabControl1.TabPages[e.Index];

    // Get the real bounds for the tab rectangle.
    Rectangle _TabBounds = tabControl1.GetTabRect(e.Index);

    if (e.State == DrawItemState.Selected)
    {
        // Draw a different background color, and don't paint a focus rectangle.
        _TextBrush = new SolidBrush(Color.Blue);
        g.FillRectangle(Brushes.Gray, e.Bounds);
    }
    else
    {
        _TextBrush = new System.Drawing.SolidBrush(e.ForeColor);
       // e.DrawBackground();
    }

    // Use our own font. Because we CAN.
    Font _TabFont = new Font(e.Font.FontFamily, (float)9, FontStyle.Bold, GraphicsUnit.Pixel);
    //Font fnt = new Font(e.Font.FontFamily, (float)7.5, FontStyle.Bold);

    // Draw string. Center the text.
    StringFormat _StringFlags = new StringFormat();
    _StringFlags.Alignment = StringAlignment.Center;
    _StringFlags.LineAlignment = StringAlignment.Center;
    g.DrawString(tabControl1.TabPages[e.Index].Text, _TabFont, _TextBrush,
                 _TabBounds, new StringFormat(_StringFlags));

}

In Winforms you can change the DrawMode and paint all the captions on yourself.

See the MSDN Example.

Another, less elegant option is to set the font->bold property of the parent form/control to true, which will make everything bold including the tab names and then set bold to false on all the controls you don't want bold.
