Forms Data Controls :: Multiline Grid Cell Displays Correctly In IE But Not FireFox Or Safari

Using C# in the ASPX file, I define a grid:

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False"
OnRowDataBound="OnRowDataBound"
BorderStyle="Double" Caption="Club's Dashboard"
CaptionAlign="Top" Width="292px" EnableTheming="False"
HorizontalAlign="Left" CellPadding="5">
<HeaderStyle BackColor="Fuchsia" Wrap="False" />
<RowStyle HorizontalAlign="Center" Wrap="False" />
<columns>
<asp:boundfield datafield="B2" headertext="." htmlencode="false"/>
<asp:boundfield datafield="PRPT" headertext="TestA<br/>TestB" htmlencode="false"/> ........ Notice the .<.b.r././.> TAG between "TestA" and "TestB"
</columns>
</asp:GridView>

In the ASPX.CS file I define a datasouce and manually populate it.

DataColumn MDC = new DataColumn();
MDC.AllowDBNull = false;
MDC.AutoIncrement = true;
MDC.AutoIncrementSeed = 1;
MDC.AutoIncrementStep = 1;
MDC.ColumnName = "B2";
MDC.DataType = System.Type.GetType("System.String");
MDC.Unique = false;
MDT.Columns.Add(MDC);
MDC = new DataColumn();
MDC.ColumnName = "PRPT";
MDC.DataType = System.Type.GetType("System.String");
MDT.Columns.Add(MDC);
I then manually fill each row:
DR = MDT.NewRow();
DR["B2"] = "Test1<br/>Test2";
DR["PRPT"] ="Test3<br/>Test4";
MDT.Rows.Add(DR);

When the Grid is viewed using IE - both the Header and the data rows properly display the cells with multiple lines. When displayed using Firefox or Safari - only the Header utilizes multiple lines - the data rows are on a single line ---- "Test1Test2" what needs to be done to display multiple lines in all three browsers.
