Hello,

We are looking into some performance issues in our applications using the Infragistics components.

This includes the UltraWinGrid and UltraWinExplorerBar, so I'm not sure in which subforum to post.

In attachment you will find a sample application, it has a form with a UltraWinExplorerBar with a UltraWinGrid in the group container. And a second UltraWinGrid outside of the explorer bar. Both grids have about 1000 records.

While this sample application does not take long to load, there is still a noticeable delay between the first display of the form, the moment the ultraexplorerbar becomes active and then the grid becomes active. Our real applications contain many other controls and more records which make the total loading time longer then this example.

Question 1:

Do you have any suggestions about the general performance ? This application is rather simple, our real life examples are a lot more complicated and the loading time of infragistics controls seems rather slow. We've measured in a real life application and the initializecomponent code of 1 ultrawingrid was about 0.6 seconds, which seems very long. This is before any data is loaded !

We've already read the general ultrawingrid performance guide which helped a lot to speed up grids, but this seems to has no effect on the initializecomponent code.

Question 2:

Do you have any suggestions or tips about rendering performance ? The controls seem to load in "chunks" instead of all at once. Especially the UltraWinExplorerBar seem to be affected by this.

Kind regards,

Michael
