Just started using this grid and still are quite overwhelmed with all the properties and stuff.. so bare with me if I just have missed something really simple

I have a grid that's connected to a DBQuery, and shows a few Columns from this.

I also added another column which I intend to fill with my own data depending on the data from the DB and also an image.

In short I want to get three values from the DB and analyze/format them and print the new value for each row I fill with data..
I think i found something in the Help to do this, using:
"/../
 for ARecordIndex := 0 to myView.DataController.RecordCount - 1 do
/../"

Is this the correct way to do it, or are there some event that triggers when each row get filled with it's data?

That was a bonus question and this is what I think will be more difficult for me:
I also wish to display an Image inside this cell just before the text that I manually put in..

Is there anyone that can help me?
