So to avoid postback , then
I have used Appenddatabounditems= true
then adding 'Select' and '-1' as default in the Collection property..
To display default value..

Value of Second dropdownlist - the data wil bind to the Third
Dropdownlist but at that time.. each data added twice...
how shall i resolve the issue...???
