Hi Ajeet,
Thanks you for your sample.
I've added some code to display the time for Load and Save button click.
I've also found your sample is slow. I've run it in VS2005/c# IDE debug mode and syncfusion studio V4.4.0.51. My laptop is HP,WinXP, Intel(R) Core(TM) Duo CPU T7700@2.40GHZ,3.00GB of RAM.
I tested it for 4 cases. Please see my attached screen shots.
Case A: No wireless Internet connection and MSN,using Battery Power
Case B: No wireless Internet connection and MSN,using External-Plug Power
Case C: Having wireless Internet connection and MSN,using Battery Power
Case D: Having wireless Internet connection and MSN,using External-Plug Power
You can see using laptop battery and internet connection will greatly slow down the Diagram() and Open file.
I've repeated these 4 case a few times and the results are quite stable.
Why could internet MSN and Battrey Power affect the New Diaprogram() line so significantly?
Thanks,
Lan
