Syncfusion Grid technical question

I have been using Syncfusion Grid(v8.4.0.10).
However, in a customer's PC was having problems.
In addition to the PC did not have this problem.
problem PC Model : Samsung DB-P60 (Windows XP Professional)
Graphics card : NVIDIA GeForce 7600GS
The problem is the increasing memory and slower speed.
1. Only the PC is slow. (Items (20 count) Loading takes more than 90 seconds.)
2. Was execute only. but the memory has increased.(Observed for 3 hours at the PC)

XCeed grid had used previously.
November 2010 was replaced by syncfusion grid.
Previous versions were running on the PC. That was normal.
(There is no change in the program.)

Questions
1. When the behavior Grid -> Is it have relate PC model and the graphics card?
2. When the behavior Grid -> Do you used DirectX or Windows graphical features?
3. When the behavior Grid -> Is it have history function?

What is the solution?
I will wait for answers.

Thank you.

Hi jungjin,

Syncfusion WPF Grid control loads the cells only by the drawing the visual content of the cells and not loading the UI Elements in the Grid control using Visual tree. Hence the performance of the grid WPF will be high and consume only less memory to load the grid control. WPF Grid control does not load it’s content based on the PC model and the graphics card in the machine.

WPF Grid only draw the rectangles and cell values using the drawing methods and it does not use any DirectX or Windows graphical features to load its content.

We do not maintain any history function in the grid control as it will draw the visual only for the visible part of the grid in the scroll viewer. This makes the grid control feel light weight and load the element with less memory and high performance.

If you are able reproduce the issue still please update us with a simple sample to reproduce the issue. Hence we could check with the issue and update you with the solution.

Please let us know if any queries.

Thanks
Kamal.
