WebExcelExporter works but Spreadsheet has no column headers?

I am having the same problem, its not the fontcolor.

This is the definition of my grid:

<ig:WebDataGrid runat="server" ID="PoolGrid" AutoGenerateColumns="false" Width

="100%"

OnInitializeRow

="PoolGrid_InitializeRow"

DataKeyFields="PoolId" style="margin: -2px 0 0 0"

<Columns

<ig:BoundDataField DataFieldName="Name" Key="Name" Width="130px"

<Header Text="Pool Name"

</ig:BoundDataField

<ig:BoundDataField DataFieldName="PoolType" Key="PoolType" Width="60px"

<Header Text="Pool Type"

</ig:BoundDataField

<ig:BoundDataField DataFieldName="DomainAssignment" Key="DomainAssignment" Width="140px"

<Header Text="Domain Assignment"

</ig:BoundDataField

<ig:BoundDataField DataFieldName="Description" Key="Description" Width="130px"

<Header Text="Description"

</ig:BoundDataField

<ig:BoundDataField DataFieldName="RolesAsString" Key="RolesAsString" Width="70px"

<Header Text="Roles"

</ig:BoundDataField

<ig:BoundDataField DataFieldName="AttributesSummary" Key="AttributesSummary"

<Header Text="Attributes"

</ig:BoundDataField

</Columns

<Behaviors

<ig:Activation Enabled="true"

<ig:Selection CellClickAction="Row" RowSelectType="Single" Enabled="true"

<ig:EditingCore AutoCRUD

="False">

</ig:EditingCore

</Behaviors

</ig:WebDataGrid

As you can see nothing special.

This is the code to export:

this

.eExporter.DownloadName = fileName;

this.eExporter.DataExportMode = DataExportMode

.AllDataInDataSource;

this.eExporter.WorkbookFormat = Infragistics.Excel.WorkbookFormat

.Excel2007;

this.eExporter.Export(false, this.PoolGrid, this

.SessionsGrid);

Any idear what direction to look for?
