Hi ,
We had a view where we are showing around 25 columns in the Silverlight RadGridView . On using the default template with just sample data , this seems to be taking minimum around ~3.5 seconds for showing the data (on a Asus UE31 laptop with 8Gb ram/i5 1.7Ghz Dual Core at 1920 x 1080 res). On Running Profiler most of the activity seems to be in GridViewVirtualisingPanel's Measure Override method even though I've set up default column width and Heights. This time varies with the client resolution and becomes better at lower resolutions but much worse for higher res/worse machines.
Are these type of performance numbers visible in your tests as well and could you suggest any ideas on improving this . Ideally we'd want to get it in the 1-1.5 sec range.
Also wanted to know from your tests ,does this number degrade ,when the data set size increases to a very big set(0.5 million rows) . From my Tests with mock data of 50000, it seems UI rendering is the step that results in perf degradation and not the data set size?. At huge row size though (>20000) the Bindings also seem to be factor.
I could share a sample project which reproduces this over email as the thread doesn't allow me upload anything other than images.
