How to bold only icon of checkBox

Hi,

There is a Checkbox in one cell and it works well with the code below.

    For i As Integer = 1 To dataList.ColumnCount - 1
      dataList.Cell(dataList.LastIndex, i) = rs.IdxField(i).StringValue
      dataList.CellType(dataList.LastIndex, 1) = dataList.TypeCheckbox
      //dataList.CellBold(dataList.LastIndex, 1) = True
    Next

Here, I want to only make the icon of ‘checked’ bold and keep the text the normal font.
Is it possible?

Not using the built in listbox
You would have to draw your own check box with a bolder check icon
