I experience a decent bit of visual lag when panning or zooming (on several computers) when I use the mouse (i.e. click and drag, mouse wheel, etc.) on any loaded maps - including the samples. It makes usability pretty clunky and I was wondering if anybody out there knows of any tricks to get it a little more responsive.
sometimes setting WindowAnimationMode="None" on the map helps a bit.
but the key to making a good optimization is knowing where the map is slowing down. how many layers are you using? are you using a shapefile datasources? if so, how large are the shapefiles?
Yea, I noticed the animationmode property after setting this. It definitely helped a little. I have two layers, using the standard world and US shapefiles. Essentially, the same exact setup as the multi-layer example in the help documentation.
hmm... i don't see how those two small shapefiles would lead to any performance problems. do the DV samples at samples.infragistics.com seem slow to you?
Did this issue resolved. I have the similar problem.
I use 3 layer:
First layer has the shape file with US. map background.
Second layer has about 600 symbols created during initialization.
Third layer has about 400 paths created during initialization.
The zooming or panding takes about 3 seconds to complete. Use WindowAnimationMode="None" helps a little bit but not much.
I would like to have it completed within 1 second. Is any tricks can help?
Thanks
Have you tried this scenario with the latest release of the product? Panning performance was increased manyfold recently.
Hope this helps!
