Did you check the link I've posted? There is a full source code
available...
hello
yes but in that they are using dll file that i can't use in my
application as my company is not allowing me to use dll file so i
prefer only code and javascript and i've one javascript but problem is
that it uses static array and i want to fetch data from db and then
want to assign to the array..with static array it works fine...here's
my code
actb.js file code ::

this all code works fine...but i want to to fetch data and want to
assign to javascript array so i can display them when user type in
textbox...do you know how to pass array from code behind to javascript
and assign it to javascript array.
I AM USING VB.NET2003 OR FRAMEWORK 1.1...
I think it's not possible to pass array to javascript so i tried to
fetch value from db and assign it to string like
dim str as string
dim i as integer
for i=0 to ds.tables("txt").rows.count-1 step 1
str += " ' " & ds.tables("txt").rows(i).item("vname")
& " ' "
next 1
but how can i split this thing in javascript and assign it to
array....
