Why won't the following code color my col header cells. As the following Debug output indicates, the
.iGrid1.ColHeaderBackColor(i) = 15132391 and .iGrid1.ColHeaderBackColor(i) = 11389944
statements seem to set the right values, but when the grid is shown, the header cells aren't coloured.

However the
.iGrid1.ColHeaderText(i) = "AAAA"
statement does update the header text and this is shown on the grid

Sub expenseEntry()
    Dim colHeader As Object
    Dim gridWidth, i As Long
    
    
    With uExpEntryDlg
        .acTypeCB.AddItem ("Expense")
        .acTypeCB.AddItem ("Income")
        .acTypeCB.AddItem ("Cap Movt")
        .acTypeCB.AddItem ("ExtraOrdinary Expense")
        .acTypeCB.AddItem ("Miscx")
        .acTypeCB.AddItem ("XXXXX")
        .acTypeCB.ListIndex = 0
           
        fillCol
        Set colHeader = .iGrid1.AddCol(lWidth:=36, sHeader:="A/C#")
        fillCol
        Set colHeader = .iGrid1.AddCol(lWidth:=144, sHeader:="A/C Name")
        fillCol
        Set colHeader = .iGrid1.AddCol(lWidth:=360, sHeader:="Transaction Description")
        fillCol
        Set colHeader = .iGrid1.AddCol(lWidth:=72, sHeader:="Trans Date")
        fillCol
        Set colHeader = .iGrid1.AddCol(lWidth:=118, sHeader:="Amount")
        fillCol
        Set colHeader = .iGrid1.AddCol(lWidth:=18, sHeader:="Tax")
        fillCol

            End If
            Debug.Print i & "     " & .iGrid1.ColHeaderText(i) & "     " & .iGrid1.ColHeaderBackColor(i)
        Next i

By default, the OS visual styles are use to draw the iGrid column header. If so, the column header background comes from the OS and there is no chance to apply our custom color formatting.

To make it work, simply disable visual styles in the iGrid header using the following statement:

iGrid1.Header.UseXPStyles = False
