Hello,

Are you using CellStyle and the CssClass property to set the style?

I think this could be the correct and expected behaviour - the appearance set through styles has higher priority than Css.So I am not sure this classifies as a bug. You are still correct though that it works for some Css styles and not for others

The point is that some default Css styles are applied to the cell (<td> html element) and some of them involve font-size, font-name, etc. This is the default (or chosen) skin of the grid - this is what makes the grid look good by default. However, if you do need to override that, it is still possible using the reserved Css rule !important - this explicitly overrides any defaults you have for the grid.

Here is a sample:

 .redCell
    {
        color: red;
        font-size: 20px !important;
    }
   
    </style>
   
    <igtbl:UltraWebGrid ID="UltraWebGrid1" runat="server"
        DataSourceID="AccessDataSource1" Height="200px" Width="325px">
        <Bands>
            <igtbl:UltraGridBand>
                <Columns>
                    <igtbl:UltraGridColumn BaseColumnName="FirstName" IsBound="True"
                        Key="FirstName">
                        <Header Caption="FirstName">
                        </Header>
                    </igtbl:UltraGridColumn>
                    <igtbl:UltraGridColumn BaseColumnName="LastName" IsBound="True" Key="LastName">
                        <Header Caption="LastName">
                            <RowLayoutColumnInfo OriginX="1" />
                        </Header>
                        <Footer>
                            <RowLayoutColumnInfo OriginX="1" />
                        </Footer>
                        <CellStyle CssClass="redCell" />
                    </igtbl:UltraGridColumn>
                    <igtbl:UltraGridColumn BaseColumnName="EmployeeID" DataType="System.Int32"
                        IsBound="True" Key="EmployeeID">
                        <Header Caption="EmployeeID">
                            <RowLayoutColumnInfo OriginX="2" />
                        </Header>
                        <Footer>
                            <RowLayoutColumnInfo OriginX="2" />
                        </Footer>
                    </igtbl:UltraGridColumn>
                </Columns>
                <AddNewRow View="NotSet" Visible="NotSet">
                </AddNewRow>
            </igtbl:UltraGridBand>
        </Bands>
        <DisplayLayout BorderCollapseDefault="Separate" Name="UltraWebGrid1"
            RowHeightDefault="20px" Version="4.00">
            <FrameStyle BorderStyle="Solid" BorderWidth="1px" Font-Names="Verdana"
                Font-Size="8pt" Height="200px" Width="325px">
            </FrameStyle>
            <Pager>
                <PagerStyle BackColor="LightGray" BorderStyle="Solid" BorderWidth="1px">
                <BorderDetails ColorLeft="White" ColorTop="White" />
                </PagerStyle>
            </Pager>
            <EditCellStyleDefault BorderStyle="None" BorderWidth="0px">
            </EditCellStyleDefault>
            <HeaderStyleDefault BackColor="LightGray" BorderStyle="Solid">
                <BorderDetails ColorLeft="White" ColorTop="White" />
            </HeaderStyleDefault>
            <RowStyleDefault BackColor="White" BorderColor="Gray" BorderStyle="Solid"
                BorderWidth="1px" Font-Names="Verdana" Font-Size="8pt">
                <Padding Left="3px" />
                <BorderDetails ColorLeft="White" ColorTop="White" />
            </RowStyleDefault>
            <AddNewBox>
                <BoxStyle BackColor="LightGray" BorderStyle="Solid" BorderWidth="1px">
                    <BorderDetails ColorLeft="White" ColorTop="White" />
                </BoxStyle>
            </AddNewBox>
            <ActivationObject BorderColor="" BorderWidth="">
            </ActivationObject>
        </DisplayLayout>
    </igtbl:UltraWebGrid>
    <asp:AccessDataSource ID="AccessDataSource1" runat="server"
        DataFile="~/App_Data/Nwind.mdb"
        SelectCommand="SELECT [FirstName], [LastName], [EmployeeID] FROM [Employees]">
    </asp:AccessDataSource>

In this case, the font-size will be applied always for the cell in question even though there is a different default Css.

HTH,
