How to assign drop downlist datasource dynamically?

Hi,
I have 20 drop downlist in my page,
Named as :
DropdownList1
DropdownList2
DropdownList3
- - - - - - - - - - -
- - - - - - - - - - -
- - - - - - - - - - -
- - - - - - - - - - -
DropdownList20

and I have to assign the same array to all the dropdowns, so instead of assigning manually to all the drop downs I want to use for loop.

like

for(int i=1;i<=20;i++)

{
eval("DropdownList"+i).DataSource=options;
eval("DropdownList"+i).Databind();
}

But by using eval this not possible and I am unable to use the typecasting too. can any one please help regarding this.

Thanks and Regards,
Subhendu Swain

Hi,

You can create an array of dropdownlists or a List<DropDownList> that you populate with all your dropdownlists. Then you iterate through that list (thanks to "foreach") and do whatever you want to do.

you can use in Page Load
"dropdownlistid.datasource = datasourcecontrolid
dropdownlistid.databind()"
