I need to render a graph in a datagrid. I was thinking of rendering one canvas element in each row’s first column/cell and then render a dot and a line there. Now the thing is that there will be thousands of rows in the datagrid. Before i begin implementing this i would prefer insight from anybody who already has experience on this. Is this aproach going to perform slowly? Am I choosing the best path?
If you don’t show all the data at once to the user, you could leverage data virtualization concepts.
This PDF helped me understand key concepts of data virtualization.
That said, using a DataGrid is not a good idea. The bigger the amount of data, the lower level component you should use. In your case, that would be ItemsControl.
I believe a quick look at both their definition is worth all the explanations.
I once saw a blogger on msdn who showed an example where he would load over a million of drawings and it would not lag one bit. It is totally possible, but I can’t find that link anymore.
