I am binding months to a list 0-13 items default selection is 0 months duration, and years 0-8 items and 0 years is the default selection.As I know there are always going to be 12 months in a year, I could use selectedvalue or selectedindex without any perceived problem. Is there a reason why I should not use either/or of the two properties to select a list item?

I am using SelectedIndexChanged in the DropDowList and it works fine and populates a GridView based upon a site selection.
Is there there a way I can reset the SelectedIndexChanged so if user wants to refresh the GridView they would open the drop down list and click on the same selection again?
I am populating a DropDownList from a text file (class requirement).
The file is read in the Page_Load method and the DropDownList is populated then.
When I press the Submit button, throughout the process of the code it is supposed to get the SelectedIndex and use it to grab a value out of a List(Of ).
The thing is, nothing is ever passed through. I even setup an alert box and it passes right over the alert box and never even triggers it, but gives me an Index out of range error when it moves to the line right after the Alert.

How to get the selected item from the listbox in the selected index changed event. I tried: Label1.Text = ListBox1.SelectedItem.Text; It is giving me object set to null reference.
foreach (ListItem item in ListBox1.Items)

{
//lblResults.Text += item.Text + "

Label1.Text = item.Text;

No use, no value coming in to label.

I have a problem in setting the selected index /value in a drop down list. The list is bound by a Linq query and I want to add an item at the top of the list and set it as the selected item.
THis is the code i am using
ListItem li = new ListItem("Select", "", true);
list.DataSource = (from ap in edc.Approvers
where ! ap.approverEmail.Equals("")
orderby ap.approverEmail
select new {ap.approverEmail}).Distinct();
list.DataTextField = "approverEmail";
list.DataValueField = "approverEmail";
list.DataBind();
list.Items.Add(li);
list.Items.FindByText("Select").Selected = true;
The listItem li is the item i want to be first in the list and also selected. Adding this before the databind just loses the item.
I have a user control that has some drop down lists. These DDLs are used by the user to filter their product search on my search page. A button is used to post the form and get the results of the product search. Those results are displayed on the results page, which also has the search filter user control on it. I'd like the results page to have the values of the DDLs be preserved from the search page. Example: user selected color of red and size of large on the search page. When the results page is displayed, I'd like the selected color to be red for the color DDL and the size to be large for the size DDL. How can I do this?

View 1 RepliesI have a simple query based on the index changed event of a dropdownlist in ASP.NET. The scenario is i have a dropdown list bearing a collection of items (say ONE, TWO, THREE, FOUR, FIVE) with the default value selected as 'ONE'. Now, when the client changes the index (say the client selects 'TWO'), a confirmation box is prompted asking 'Are you sure want to change the index?' with the buttons YES & NO. Now, the problem is, if YES button is clicked then its working fine as the index is changed. But when NO button is clicked in the confirmation box, I do not want the index to be changed to 'TWO' and it should be holding the previously selected value which was 'ONE'. How can I do this? For which event should I write the code, as I cant think of writing the code for the IndexChanged event because here the index change has already occured and since there is no 'IndexChanging' event in ASP.NET, where shall i write the code

I have a gridview that receives data based on selection from a primary dropdownlist object. Works.
Within the gridview, there is a dropdownlist whose selected index is based on the query from the primary dropdownlist. Works.
Problem.
How do I force the used to change whatever value that the dropdownlist contains after they make their initial selection from the primary dropdownlist; except the default value of "make a selection".
Gridview, contains a checkbox which drives whether a selected row is inserted into the data base. The databind in done using an ObjectDataSource on the presentation page, not in the code behind.

I thought this would be pretty simple, and in fact it's working on another dropdownlist on the same View, so I'm hoping I missed something very small that is easy to fix. Here's my code:

When I step through the code, the 'Active' option's 'Selected' property is being set to true. That's expected. But when the View renders, it's not selected and a look at the page source shows that the selected property isn't set. What is the problem here, and what's the solution?

I have a couple pages that are all pretty similar. Each of these pages consists of some number of views. Roughly speaking the first four views on each page are the same. The first page has a listbox and a textbox, then next several pages have listboxes. Because these views are the same between all the pages, and because the code behind them is the same, I built up the first page and got it working, then copied and pasted the information over for the other pages. The pages all differ in what the textbox does, but the listboxes are all identical in every way.
So, what I am seeing is that the original page works perfectly. When I go to any of the other pages, the behavior is bizarre. I was a bit surprised to find when the SelectedIndexChanged event was raised for the listbox, but it's fine. In the SelectedIndexChanged event, some minor stuff needs to happen as long as the selectedIndex is not -1. I am getting the SelectedIndexChanged event when it should happen. I see this by putting a breakpoint in the event handler. The SelectedIndex is ALWAYS -1. I can't get the SelectedIndex to be anything else, though it works in the original page from which the code was copied.
Naturally, I assumed that I had overlooked some change in the copying and pasting. That doesn't appear to be the case, but it still makes the most sense. The event is triggered by a change in the selectedIndex on the page that is currently loaded. However, the SelectedIndex hasn't changed because it was -1 and is still -1. The SelectedItem is still nothing, as it was before. There also isn't any problem that I can find with the copying and pasting. I even tried renaming two of the listboxes on one of the pages so that they would be truly distinct from the page that was working (different ID, which shouldn't matter since they are different fields). This had no impact. Nothing I can do will cause the SelectedIndex to be anything other than -1.
