Hi,

I have 2 WebHierarchicalDataGrids on a page, each of them in an asp:UpdatePanel, they have both a custom pager like the one of the samples (WebDataGrid), the second grid has a summery row.

Now what happens if I change the page of the first grid:

Error message: The method or operation is not implemented.

Source: Infragistics35.Web.v10.3

Class: DataRecordCollection

Method: GetCount Parameters: · fieldName

It looks related to the summery row. So I changed Enabled True to False and the error does not appear and the requested page change occurs correctly.
