Are the RowCursor which are accessible by creating QueryDef and Join in ArcGIS Pro SDK are read only? Updating the Row iterating through RowCursor is not possible.
using (Table joinedTable = join.GetJoinedTable())
using(RowCursor rowCursor = joinedTable.Search(null,false))
{
while (rowCursor.MoveNext())
{
using (Row row = rowCursor.Current)
{
}
}
}
