I have an application (for displaying financial information) that has for example 20 dynamic unbound datagridview controls, each has 18 columns and about 5 rows
I have routines that can update any cell by its grid name row index and cell index,this routine is on a constant cycle every 800ms applying changes to the cells and changing their colours accordingly. At any one pass I am changing on average about 40 cells
I need to reflect changes in 'realtime' and I have all my scavaging code as well as cell coordinate and change code down to about 400ms using threading on quad core CPU's
1) The paint/refresh time in the grids are poor, I know my routines end well before the actual paint happens
2) All the grids are in a TablePanel and when scrolling the panel, the paint is even worse, just turns into white lines until a full refresh is done
3) I can't flash cells, i.e. change their colours for 5 seconds and revert to white without freezing the application (cant work out how to access a control from one thread to another)
I need an alternative, I come from an ASP.NET background, and using AJAX on an html page to display this much info, and flash cells etc is very simple, and a browser seems to have no problems with painting during scroll, or replacing cell contents without having to struggle. I am thinking about embedding a web control and creating HTML on the fly and sending JS commands to change cells etc. This is alot of work for me and I would like to know anyones thoughts on alternates??
