Hi,
In my current project, I have written a web page containing a Hierarchical RadGrid.
On each data row of the grid, there are 3 CheckBoxes set to edit mode.
The users are able to check or uncheck any of the CheckBoxes and click the Submit button to save the data on the back-end.
The data displayed on the grid are stored on a DataSet.
All operations on the web page are done on the server-side.
The development and testing stages have been completed, and the project is in the UAT stage right now.
However, there seems to be a performance problem with the web page when there are many data rows.
It is very slow to perform the following operations:
- to open up a tree level (by clicking the <)
- to check or uncheck the CheckBox
The screenshot of the web page can be found here.
The ASPX source code can be found here while the ASPX.CS source code can be found here.
When I did a View Source on the browser, the file is pretty huge and can be found here.
Can you please help me with the following:
- how to improve the performance for the operations above.
- how to reduce the size of code (in particular the ViewState).
- if there is any problem or weaknesses in my approach as shown in the source code.
Regards,
Herman

Hello Herman,
If you work in hierarchy mode to optimize the control's performance, you can use a combination of ServerOnDemand and Client hierarchy load modes based on the information from the resources below:
http://www.telerik.com/help/aspnet/grid/grdhierarchyloadmodes.html
http://demos.telerik.com/aspnet-ajax/grid/examples/hierarchy/hierarchyloadmodemixed/defaultcs.aspx
Other useful tips for performance optimizations can be found under the 'Performance tips and tricks' chapter in the RadGrid for ASP.NET AJAX online help and this page:
