Hi,

I'm new to the use of this control having previously used the standard UltraWebGrid so my apologies if I have missed something obvious.

I have a two level grid displaying projects and the jobs within the projects as a child level.  My Data Access Layer presents the Projects and Jobs as objects hiding the database layer from the control and as such I am using manual load on demand.

I have defined my grid as :-

<ig:WebHierarchicalDataGrid ID="whdgProjects" runat="server" AutoGenerateColumns="False" AutoGenerateBands="False" Height="650px" Width="98%" DataKeyFields="Id">

<Behaviors>

<ig:Paging PagerAppearance="top" PageSize="20" Enabled="true" />

</Behaviors>

<Columns>

<ig:BoundDataField DataFieldName="Id" Key="Project ID" Header-Text="ID" Width="50px" ><Header Text="ID" /></ig:BoundDataField>

<ig:BoundDataField DataFieldName="CreatedDateTime" Key="CreatedDateTime" Header-Text="Created" Width="130px" ><Header Text="Created" /></ig:BoundDataField>

<ig:BoundDataField DataFieldName="Location" Key="Location" Header-Text="Location" Width="250px" ><Header Text="Location" /></ig:BoundDataField>

<ig:BoundDataField DataFieldName="LocationPostcode" Key="PostCode" Header-Text="Post Code" Width="100px" ><Header Text="Post Code" /></ig:BoundDataField>

<ig:BoundDataField DataFieldName="Agent" Key="Agent" Header-Text="Agent" Width="150px" ><Header Text="Agent" /></ig:BoundDataField>

<ig:BoundDataField DataFieldName="ContactName" Key="ContactName" Header-Text="Contact Name" Width="150px" ><Header Text="Contact Name" /></ig:BoundDataField>

</Columns>

<Bands>

<ig:Band Key="JobsBand">

<Columns>

<ig:TemplateDataField Key="icon" Width="50px"><Header Text="TemplateField_0" /></ig:TemplateDataField>

<ig:BoundDataField DataFieldName="Id" Key="Id" Width="50px"><Header Text="ID" /></ig:BoundDataField>

<ig:BoundDataField DataFieldName="Type" Key="Type" Width="100px"><Header Text="Type" /></ig:BoundDataField>

<ig:BoundDataField DataFieldName="ContactName" Key="ContactName" Width="150px"><Header Text="Contact Name" /></ig:BoundDataField>

<ig:BoundDataField DataFieldName="ScheduledDateTime" Key="StartDate" Width="150px"><Header Text="Start Date" /></ig:BoundDataField>

<ig:BoundDataField DataFieldName="Price" Key="Price" Width="100px"><Header Text="Price" /></ig:BoundDataField>

<ig:BoundDataField DataFieldName="Complete" Key="Complete" Width="50px"><Header Text="Complete" /></ig:BoundDataField>

</Columns>

</ig:Band>

</Bands>

<ExpandCollapseAnimation SlideOpenDirection="Auto" SlideOpenDuration="300" SlideCloseDirection="Auto" SlideCloseDuration="300" />

</ig:WebHierarchicalDataGrid>

All so far so good.  My problem is that the objects have far more fields in them that I want displayed in the grid.  for the top level this is working as I expect - only the items defined in <columns> are displayed.

When I expand a project it calls the whdgProjects_RowIslandsPopulating function as I expect which creates a list of jobs for the project, creates a container grid and sets the list as the data source.  The problem is that when the child band is displayed I get columns for ALL of the fields in the object not just those which I have defined in the jobs band - indeed it seems as though this definition is being ignored.

I really need some quick assistance with this as I need to make the decision whether to just go back to the UltraWebGrid if what I am trying to do just can't be done.  

Thanks,
