I have the generation of HTML in 1 or 2 seconds (in server side).
But it takes the creation of the grid more than 3 minutes. (in client side). Using dhtmlXGridFromTable.
For instance: 1000 lines for 3 columns. (3000 cells).
Some idea how to improve the speed in the client?
Initialization from HTML not purposed to load big grids , there is no way to improve performance of such operation significantly.
You may try to output data as XML on page and init grid from XML island in SmartRendering mode.
