Thanks for clearing this up, Alex. I don't have row selection enabled on my datagrids so I do not need this constant redrawing of renderers - is there any easy way to override it or turn it off? In fact I've been doing a little more testing and this behaviour has an even bigger impact on performance than I thought - it looks like every column renderer in every row is redrawn when a single row updates - presumably for the same reason as above? So if I have a very modest datagrid with 25 visible rows each with 8 columns this means 200 cells (buttons, text, whatever) are redrawn whenever a single row is updated in the data provider? This is a big problem for me as my data represents real time prices and can change very frequently. It also explains why performance decreases when more rows are visible at once - even if the rate of row updates remains the same. Thanks for your input, Nick.
