What exactly you want to do? If you want to do some operation on onchange event od the dropdownlist then just see whether you have set the autopostback property of the control to true.

autopostback property is true..i try alot of time bt the first element that is comming from the database ,not generated the selectindexchange event.
|
|
|
|
|
Norammaly whaht happens is it fires for the change event and what would be happening in your case is it would be the default selected? In this what you can do is to add one more item to your list as the first item something like "--Select--" and then your problem will be solved.

You can do it like this, after binding the dropdownlist what you need to do is to put this line:
DropDownList1.Items.Insert(0, "select")
I think this will serve the purpose.

Yar Just Addd Autopostback = True in DropDown List.
|
|
|
|
|
i added default string in the drpdownlist.bt whn the data that is comming from the database fill the dropdownlist runtime it would not show the default string value.
tell me how can i overcome this problem?
|
|
|
|
|
Yes i got your problem make Autopostback = true
when you select you first item it will not go to selected index changed function for that you have add "Select one Item " as default string to the drop down list or you can make Autopostback=false and add one button and write the logic in Button_click function simple

if you have datset which contains the data from database then try this code
for (int index = 0; index < ds.Tables[0].Rows.Count; index++)
{
object[] array = ds.Tables[0].Rows[index].ItemArray;
string str = array.GetValue(0).ToString();
DropDownList1.Items.Add(str);
}

First let's clear up some confusion:
1. You can't use static variables to store user specific data, as a static variable is shared by all threads.
2. A hidden field is only useful if you want to send the value from one page to the next, as an alternative to relying on the session.
3. A session variable can not become null during the execution of a page. If it exists when the execution starts, it will exist when it finishes.
In your code you put the value in the variable userId, just use that variable. There is no reason to put it anywhere else during the execution of the page.
