Add popup taking more time to close in cancel mode in radgrid

[Guru]

I am getting more time to close the add/edit popup, while cancel the popup in radgrid.For all grids getting same problem and getting timeout while binding more than 5000 records in radgrid from the database.Please some one give me the solution.I am using Telerik 2011.3 version.

make sure you are not refreshing the grid after a cancel
if you populate the grid through a NeedDataSource event on the server then the grid should not refresh when the popup closes

Thank you for your responce, included the NeedDataSource event for the grid.Whenever the popup closes,then it is taking more time to close.If in insert mode closing fast.

Please can you give me the solution.
