Yep... Its not allowing.
To overcome this, the only solution is inserting an item at the index 0 and set the SelectedIndex to 0.

If dropdown is having only one value, it won't post back on change. Why don't you add a (Choose any item) to index 0 and (Add new) to index 1, which solves the problem.

i am populating the dropdownist from database as well.if i add the string choose the item before updating the dropdownlist , it excludes this item from the list and fill the dropdownlist with items from the database.
now at last , after updating the control with the database , i am inserting two new static items at Runtime.
1.choose the item
2.add new.
now the problem is , i want to put the item choose the item at the top of the control and add new at the rear of the control.

Every control ,which has DataSource method,has starting index 0.
So how can you select index -1?
Sonia Gupta wrote: i should make the selected index = -1
You can not but you can give value -1 to ListItem of dropdownlist and check what you want.

if understood what u want my suggestion is:-
save the result comming form the database in DataTable (dt)
then make for loop to insert the values
but the first item let be
ListItem li1=new ListItem ("Select...","-1");
and add it into ur dropdownlist.then add the item u want to.
if u bond the List u cant add the item with the value "-1"

I think, you have enabled AutoPostback property. As you populated the DropDownList using AJAX, it difficult to maintain the ViewState after the Page postbacks.

Hi Guffa , Navaneeth,
I posted this query earlier.But not getting , how to overcome the problem .
i have a java script funciton and a button server control in aspx page, which i am invoking at the form closing.Now the problem is , the same function is executing on button click as well as on the form closing button.
i was told by Guffa in this link and in this link
by setting the variable in onclick of the button, and check the value of the variable in the abc function.
My question is how i should declare the global variable , and how i should check it's value in the funciton

Please don't address the question to specific member(s). This might prevent others replying to your pos. As Guffa said in his post, you can declare a variable inside a script and outside a function. This will be treated as public variable. See the example below
<script language='JavaScript'>
<!--
var Submitted = false;
function window_onbeforeunload(e) {
if (!Submitted) {
return(confirm("Are you sure to exit"));
}
}
</script> When any button is clicked, make this Submitted=true, which will avoid displaying the message.
Hope it helps

When you are writing make Submitted=true, which will stop the message from appearing. This value we are checking in the unload function, and message is displayed when this is false. So make it true, and message won't be displayed.
