dear sirs
i have DropDownList bounded to a datasource , when i read its SelectedValue , the displayed item is changed in the dropdownlist

whatever i select , the dropdownlist changed to item2
thx
dear sir
i discovered the problem became more complicated than i thought
some more background is needed
the dropdownlist is binded to datasoure ( username , password , user rank), i display the username and i return the password in selected value and the dropdownlist sorted by rank
indeed the dropdownlist working so fine and the selected item remains even after reading selected value but IN ONLY ONE COND. that such username has a unique password
for example:
user pass
aaa 1234
bbb 1234
ccc 34343
dddd 67657
if i choose ccc it will return 34343 selected index 2
if i choose dddd it will return 67657 selected index 3
if i choose aaa it will return 1234 if aaa is higher rank than bbb
if i choose bbb it will return 1234 selected index 1
please kindly help me
thx alot
bye

set AutoPostBack to false.
|
|
|
|
|
DropDownList.SelectedValue is already false
|
|
|
|
|
whether in its Page_Load event has been added
like this:
(! Page.IsPostBack)
{
}
to be this
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
}
}
