How do i do this in drop down.
I have an ASP.NET GridView that has four columns. The first three are typical BoundField elements bound to a DataTable. The forth is a TemplateField element that I create a DropDownList in on the OnRowCreated event for the GridView.
What I'm attempting to do is walk down the data source for the GridView when a button is pressed. I really just need to get the values for columns one and four of each row. The first three columns have data as expected but the forth is displaying as empty. Is this because it wasn't a part of the DataTable originally? Is there any way to get the value for each drop down as I've described it, or will I need to rework this so each drop down list is a part of the DataTable?
This is the Grid am using ....

Every thing is working fine ....

I have a list with 2 sorts of items. Items that have actual values (1,2,3,4 etc) and items that are like group headings so all their values are set to 0. If someone decides to select a group heading - which has a value of 0, is it possible to redirect them to my 'Select an item' item which has a value of ""?
If worse comes to worse, I can just reconstruct the entire list, although if possible I'd like to avoid it.
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 2 dropdownlists, the second (department) cascades from the first (division). I use a jquery script to update the second drop down list. When the user clicks submit, the underlying model is updated, apart from the new value for department. 2 ideas I have for fixing this are; a) Generate a postback. Prefer not to do this because of bad user experience. b) With a JQuery change event, make a call to server side and set a ViewData variable that I can use to update the field in the model later.
However there must be a better way. This is the view;
<%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/AdminAccounts.master"
i have a dropdown list
<asp:DropDownList ID="DDName" runat="server" AutoPostBack="True"
DataSourceID="sdsName" DataTextField="Name" DataValueField="name_ID"
Width="179px">
</asp:DropDownList>
the problem that it is not causing post back on the first selection but on the second, I mean if i select from drop down list first selection no post back on the server,but when i select another item from the list (the second click on a different list item )
I have the following scenarion. I have a range of drop down menus where a clietn can select. The code below is wrapped in an update panel but without this, the button click fires a method to retrieve the number of products. So for example, an item is selected from ddlCategory, the btnValidate is clicked and the label returns the number of products within that category.I have the following code for an update panel - I'm just not sure how to implement if effectively.
<asp:UpdatePanel ID="UpdatePanel1" runat="Server">
<ContentTemplate>
<asp:Label ID="lblSearchResultsStatus" runat="server" Text="Number of results found: "></asp:Label>
<asp:Label ID="lblSearchResults1" runat="server" Text=""></asp:Label>
<br />
<br />
<asp:Button ID="btnValidate" runat="server" Text="Validate Search"
OnClick="btnValidate_Click" Width="120px" />
</ContentTemplate>
</asp:UpdatePanel>
How do I go about wiring the update panel so that when a drop down list item is selected, the buttong is effectively clicked?
This is my first post as a newbie to asp.net.
I am in the process of creating a "news system", you can add, edit and delete news. The news items can be entered into the SQL database and you select a category where you want the news item to go into.
What I want is when someone comes to the "Edit" screen, they have a drop down list and what that does is allows you to select a category for you to edit news items from, so rather than at present having the "Edit" page display all the news items, I want people to be able to choose a category that they can edit news items in.
So far my edit page has a datagrid with the following code:

I am currently building a web site and I utilize cascading drop down lists. I am having difficulty clearing two of my drop downs. The application is utilizing Visual Basis. Here is what I found through my research but they are not resetting my drop downs after a post back:
cascadingDropDown1.SelectedValue = Nothing
cascadingDropDown1.SelectedValue = ""
I am stumped on this on and have spent several hours researching this. If anyone has a possible solution I would be greatful.
I have been having some trouble with dropdown lists reverting back to selecting the initial item in the list after a postback once a selection has been made from the dropdown list. I have read up on this and found out that a "if not ispostback then" is required.This works fine when I add in all the items in the dropdown list manually like:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If Not IsPostBack Then
ddl1.Items.Add("Select...") [code]....
However, I have over 250 items and so it is far more efficient for me to load then in by using part of a multidimensional array which is created from a text file - Definitive database.txt. I have been using the following code to do so:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If Not IsPostBack Then
'loads the definitive database array[code]...
This loads all the items into the dropdown list perfectly, but now every time a selection is made, it reverts back to the inital item on postback even though i have included the "if not ispostback then" part.
I'm trying to make the selected item the value of an asp:Label if this is possibleI am putting my drop down list in like this
For ddlAdults As Integer = 1 To strNumberSlept
CType(e.Item.FindControl("ddlEditAdults"), dropdownlist).Items.Add(new ListItem(ddlAdults.ToString(), ddlAdults.ToString()))
Next ddlAdults
And I need to add a selected item in to be the value of strSelectedItem
Dim strSelectedItem = CType(e.Item.FindControl("lblAdults"), label).Text
Not sure how to add this in dynamically

I have an asp:ListBox which contains a list of countries. Users select one or more countries and then assign them to another list box on the page.
<asp:ListBox id="countrylist" runat="server" SelectionMode="Multiple" AutoPostBack="True" CssClass="inputC" OnSelectedIndexChanged="countrylist_SelectedIndexChanged"></asp:ListBox>
In Internet Explorer, if I scroll down (say to United States) and then click it, the list scrolls back to the top. United States is still selected, if I press the "Assign" button it will appear within the second list box, and if I scroll down I can see that United States is still selected.
However, users are complaining about this, especially since it happens so quickly that they can't select multiple countries.
I tried using smartnavigation and MaintainScrollPosition, but this has had no effect.
<%@ Page Language="C#" smartNavigation="true" MaintainScrollPositionOnPostback="true" AutoEventWireup="true" EnableEventValidation="false" MasterPageFile="MasterPage.master" CodeFile="form.aspx.cs" Inherits="forms_template" %>
This behaviour is not exhibited in Firefox.

I am trying to set the item that is selected from a drop down list based on what it in the database for that particular record.
