Hi kailash r,

There are some tips that can help you get the best performance from your WinForms application using Telerik RadControls.

- Optimize assembly performance with NGen:
http://www.telerik.com/support/kb/winforms/general/ngen-telerik-assemblies.aspx

- Load the extra themes within different thread. When you have themes which are not initially set to RadControls, but are set at a later moment in the application lifecycle (for example on a button click), you can load these themes in separate thread. Please refer to this Knowledge Base for additional information:
http://www.telerik.com/support/kb/winforms/themes/load-theme-components-in-a-separate-thread.aspx

- Always surround blocks of loading data with Begin/EndUpdate for the applicable controls:
http://www.telerik.com/support/kb/winforms/combobox-and-listbox/optimizing-radcombobox-and-radlistbox-performance.aspx
This also applies to RadGridView, especially when working in unbound mode, and to RadTreeView when batch loading nodes.

- Specify the neutral resources language, to save time when loading applications's resources, if applicable, especially when you do not use satellite resource assemblies. This can be done, by setting the assembly attribute, for example:
[assembly: NeutralResourcesLanguage("en-US")]

- Using always the latest version of RadControls for WinForms.
We are constantly in a pursuit of a better performing, feature rich products. As a result in the most cases each new version of RadControls for WinForms can give you better performance along with many new features and enhancements. Also I have t mention we do really try to keep the breaking changes list very short. Please make sure you have upgraded your projects to use the latest version of RadControls for WinForms.
