Tree View in Windows APP is very slow 5 Years, 9 Months ago Karma: 0
I've had this issue on 3x and now on 4x. Our application has a tree view which look like a set of folders with the plus symbol to expand the tree.

When we click on the plus symbol to expand the tree, it expands very slow.

I wonder if there is a windows performance setting that can be tweaked to make it faster. Any ideas? Other than that performance is good. Thanks

We have the same issue on some client machines (both Windows XP and Windows 7).
We do not see this issue on MacOS clients.

We have found a temporary workaround on Windows 7: when using the native client, right-click on the properties for the GO-Global client (or shortcut), go to the Compatibility tab and disable desktop composition.

This disables the Aero interface, but fixes the "slow rendering" problem.

We would like to see a permanent fix for this. Is there a setting we can change on the server to disable desktop composition or other fancy animations?

Wow, that makes a huge difference. I never even thought about adjusting client side settings as I thought it would of been a performance setting on the server.

I think your suggested will work for now but it would be nice if GraphOn released a fix.

Try the following:

In the Registry Editor, create a key called SmoothScrollThrottle and set the value to 0.

To modify the SmoothScrollThrottle value

1. Install GO-Global Host for Windows 3.1.x or later.
2. Restart the GO-Global Server.
3. From the Registry Editor, expand the HKEY_LOCAL_MACHINE key.
4. Expand \SOFTWARE\GraphOn\Bridges\1.0.0\AppServer. Create a DWORD value and name it SmoothScrollThrottle.
5. Double-click the SmoothScrollThrottle value and type 0 in the Value data box.
6. Close the Registry Editor.

Note: If the SmoothScrollThrottle key is set to 1 or does not exist in the Registry, Windows’smooth scrolling feature will work, but the application performance issue will not be resolved.
