Hi,

I have created a WebHierarchialDataGrid with a child band. Both the AutoGenerateColumns and AutoGenerateBands are false.

The Markup code for the child band is as follows:

<

<ig:Band AutoGenerateColumns="false" Width="400px" DataKeyFields="intRowID,intEOL_ItemID"> 

<Columns>

<ig:BoundDataField DataFieldName="intEOL_ItemID" Key="intEOL_ItemID" Width="0%" Hidden="true">

<Header Text="EOL Item Id" />

</ig:BoundDataField>

<ig:BoundDataField DataFieldName="intRowID" Key="intRowID" Header-Text="Row ID" Width="0%" Hidden="true"></ig:BoundDataField>

<ig:BoundDataField DataFieldName="intProductID" Key="intProductID" Width="0%" Header-Text="Product ID" Hidden="true"></ig:BoundDataField>

<ig:BoundDataField DataFieldName="vchProductPartNumber" Key="vchProductPartNumber" Header-Text="Product"></ig:BoundDataField>

</Columns>

<Behaviors>

<ig:EditingCore EnableInheritance="true">

<Behaviors>

<ig:RowAdding Alignment="Bottom" EnableInheritance="true">

</ig:RowAdding>

</Behaviors>

</ig:EditingCore>

</Behaviors>

</ig:Band>

</Bands>

I am facing the following error while expanding the parent row:

Is there any other way to enable the 'RowAdding' feature for the child band ?
