    I have a requirement where I have to show multi column radcomboboxes in 4 columns of telerik Grid.Grid will have around 700 records with out pagination.I am using LoadOnDemand Combobox. But when I try to open a combobox , Items are not getting loaded to combobox.When grid records are around 30, Combobox loads the items normally.Please help me how to solve this issue.

    Hi Himagiri,

    I am not quite sure, that I had understood what you attempt to implement in your scenario - grid in combo or combo in grid, but in both cases you should use all techniques that you can to improve performance of the two controls. For the RadGrid use Paging or Virtual Scrolling. For the RadComboBox you could use Load On Demand with Web Services and enable the new lightweight render mode.

    All the best,
