I have an UltraGrid (v7.3) that I am trying to allow the adding of rows to.
This UltraGrid has a UltraDataSource as its datasource, where the columns are defined.

In the page load event I have the following code
UltraGrid1.DataSource = listOfEvents
UltraGrid1.DataBind();

The listOfEvents is a List<> (code is written in c# 2005)

I have set the UltraDataSource to AllowAdd, however everytime I try to add a new row when the application is running I get the following error in a popup box...

"Unable to add a row:

Unable to add a new row. Underlying DataSource does not support adding new rows."

Is it possible to add new rows in this particular setup? or do I need to have a different  underlying datasource?

Any help of this would be very much appreciated
Thanks in advance
