Related combox with filtering option

[gokul]

I am using related combo box with filtering option. The last drop down load only after press outside click. It does not load automatically after selecting the previous combo.

So I could not able to combine both the related combo box  and filtering feature . Please suggest.

Advance thanks

How are your RadComboBoxes related to each other? Are you DataSource controls for each one with the ControlParameter set to the related RadComboBox? If you show us what your page looks like, we could offer some better advice.
