Problem in loading Contents in Radcombobox

[Velkumar]

Hi,

   I have a Radcombobox in my page . More than 20 thousand records will be selected and loaded Adto this Radcombobox. While clicking this Radcombobox  it's very slow to display the contents and takes more time to respond. How can i avoid this situation.
Is there any way to load these contents in a fast manner?

Thanks,
Velkumar.

Hi,

The best approach to optimize the performance speed of RadComboBox when using huge amount of items is using the load-on-demand feature. The load-on-demand mechanism loads the items only when the user types or clicks in the field or the drop-arrow image.

When using the load-on-demand mechanism with ItemsRequested event you should:

1. Set the EnableLoadOnDemand property to true.

2. Subscribe to the ItemsRequested event and add the items there.
   
   Hope this helps.
   
   Thanks,
   Shinu.
