Hi Piotr, the main point in Datagrid for columns in "columns", but is an Array (maybe we could consider to change it to ArrayList?)
In the current implementation, you need to change all the array, and should throw away what you have and create a fresh instances of all new columns and add dataproviders with data to create rows. If we had an ArrayList, maybe making an "addItem()" or "addItemAt()" to the columns collection could handle just the addition of that column without the need to be so aggressive with the rest of data.
