Here's what I want to accomplish: I have two .aspx pages, the first page with a ddl to select a vendor (SelectVendor.aspx), and one to add a vendor (NewVendor.aspx), if it's not in the first one. If a user adds a new vendor on the NewVendor.aspx page I want the page to automatically redirect back to SelectVendor.aspx and have the ddl automatically select the new vendor that was just added. Here's where I'm at so far: If a vendor is not listed in the ddl on SelectVendor.aspx, a user can click a button to navigate to a page to add a new vendor (NewVendor.aspx). On NewVendor.aspx the user types the name of the new vendor in a textbox and clicks an insert button to add the new vendor, then the page is automatically redirected back to SelectVendor.aspx with the new vendor name added to the QueryString. For example, let's say a user adds a vendor name "Best Vendor": The page is redirected back to SelectVendor.aspx as "SelectVendor.aspx ?vendor=Best Vendor"Now all I need from here is to have the ddl programmatically select the new vendor by the text value in the QueryString.
Here is the code that I'm having trouble with from my Page_Load routine for SelectVendor.aspx:

I am trying to get a drop down and a form view to work together. I've never used form views before. I also am using the entity framework to do everything. This is also my first time with it.
I want to be able to have a drop down, that is populate from the same data source as the form view. So far that works fine.
I then want to be able to change the drop down item, and it change the form view item that is displayed. I cannot figure out how to make this work.

I have a project that queries a set of times from a database and uses these entries to populate a dropdownlist. Once the page is loaded, the user can select one of the items in the DropDownList. When the "Save" button is clicked, the Selected item value is returned to the [HttpPost] version of the controller action. This item is then stored into session. If the system returns to the page containing the dropdown, I want the saved Value to be selected in the DropDownList. What actually happens is that the DropDownList is always set to be the first item in the list.
Database Table: This data has been imported using Link to SQL

I have a small vb.net-based page, displaying a booking form with a large dropdown of movies.
now this page can be opened on two ways, one is directly (no preselection=no problem)
the second way is with a link like "page1.aspx?movieid=400" which should open the booking table and preselect the movie with ID 400.
How can I do this in VB.Net?

I have 2 dropdownlist controls (ddl1 and ddl2). When I pick an item from ddl1, it will update ddl2. The problem is when I pick an item in ddl2, it always selects the first item in the list. Is it that the ddl2 autopostback causes the first ddl1 to reload and results the ddl2 to be refreshed also? Or I didn't set something correctly?

I need to bind my dropdownlist to my dataset that is returning application specific text values. But for purposes on that page, i need to assign the value to each one starting at 0 to the number of items returned from my dataset..
Example, if my dataset only returns 1 item, the value of that item needs to be 0
[Code]....
If my dataset returns 4 items, the value of those items needs to be 0 thru 3
[Code]....
Is it possible to assign values like that to a dropdownlist from the code behind?

I have been trying for a while to populate a formview when I select an item from the dropdownlist. The dropdownlist is outside of the formview. For some reason, when I select a different item it does not change in the formview. Only the first item of the list shows up. I don't know where I'm doing wrong. I tried many things and suggested informatioin and I still could not get it to work. When I do try to switch I get this error message:
Exception Details: System.NullReferenceException: Object reference not set to an instance of an object.
Source Error:

I'm using a DropDownList with a data source which successfully populates the list. However, I want one of the items to be selected, namely the one where the value matches the path and query of the current request.
ddlTopics.DataSource = pdc;
ddlTopics.DataBind();
foreach (ListItem item in ddlTopics.Items)
{
item.Selected = item.Value.Equals(this.Page.Request.Url.PathAndQuery);
}
Using the debugger in Visual Studio 2008 reveals that item.Selected becomes true exactly once in the loop, but the rendered select has no option that is selected.

After trying many solutions listed on the internet I am very confused now. I have a C#/SQL web application for which I am simply trying to bind an ExecuteReader command to a Dropdownlist so the user can select a value. This is a VS2008 project on an XP OS.
How it works is after the user selects a table, I use this selection as an input parameter to a method from my Datamatch.aspx.cs file. Then this Datamatch.aspx.cs file calls a method from my ADONET.cs class file. Finally this method executes a SQL procedure to return the list of columns from that table. (These are all tables in Adventureworks DB). I know that this method returns successfully the list of columns if I execute this SP in SSMS. However, I'm not sure how to tell if it works in VS or not.This should be simple. How can I do this? Here is some of my code. The T-sQL stored proc:
CREATE PROCEDURE [dbo].[getColumnNames]
@TableName VarChar(50) AS
BEGIN
SET NOCOUNT ON;
[code]...
The CreateLabels method above correctly shows me the labels. But the CreateDropDownLists method just shows me one dropdownlist with nothing in it. In other words, it is not selectable. So how can I verify that the datareader is returning all 4 columns and inspect their values? I was able to find from datareader "COLUMN_NAME" but I don't know what properties to search to verify the column names.

I have a databound dropdown list (ASP.net). I want the page to load with a certain item as the selected item.
I am not adding a blank first row (thats not what i need)I find that I can get this to work with "AppendDataBoundItems" to true, but the side-effect is that I have all the items listed twice.
