Javscript-Error while Grouping

[Roxane]

Hello,

we have a mix from auto generated columns and custom columns.

GridBoundColumn boundColumn = new GridBoundColumn();
grid.MasterTableView.Columns.Add(boundColumn);
boundColumn.HeaderText = page.GetMessage(name);
boundColumn.UniqueName = name;
boundColumn.SortExpression = name;
boundColumn.Display = false;

 

When we try to Group any column in the Grid, we get the following Javascript-Exception:

Sys.WebForms.PageRequestManagerServerErrorException: An item with the same key has already been added

 

What are we doing wrong?

Thank you in advance!
Roxane
