populate multiple dropdownlist

[sweetpotatop]

Hi,

I am try to populate a number of dropdownlist with the same item,

for i = 1 to 5
dd = me.controls("dd" + Cstr(i))

itm = new listiem
itm.text ="abc"
itm.value ="aaa"

dd.add(itm)

next i
But I am getting the following error
"Conversion from string "dd1" to type 'Integer' is not valid"
when it hits this line.
dd = me.controls("dd" + Cstr(i))

Please help. I just wonder how I can refer to a control to a page
dynamically

Thanks in advance.

Hi there,

Use FindControl method of the containing control. For instance, if dynamic
controls are added into a panel try:

dd = CType(myPanelId.FindControl("dd" + CStr(i)), DropDownList)

Should help.

P.S. Remember dynamic controls have to be recreated on every postback.

Thanks for the advice, actually, all controls exit already, it is just
a matter that I need to make them visible. I tried to your suggested
syntax, but it doesn't work, it just retrun nothing.

Please advice and thanks in advance.
