Hi whanes,

What version are you running? Do you have the latest service release? Are you adding a summary in a parent or child? If you could attach a small sample that reproduces this issue, it would be awesome.

regards,

I am running v11.2, I downloaded from you guys about a week ago so I assume it is the latest release.

I am not sure what you mean about Parent or Child, but there is only a single band in the grid, however i do Group it pro grammatically first.

As far as a code sample

It goes like so

// Sample Start

grdResults.DataSource = GetDataSet();

grdResults.DataBind();

grdResults.GroupingSettings.GroupedColumns.Add("OrderNumber");

// Sample End

Then on the grid I click the summary button and select Sum, I get the error stated above.
