Asp:DropDownList Submits Page On Selection Enter?

Nov 24, 2010

I have an page which has a panel with default button and update panel and dropdownlist inside the update panel. While I fill the form when I select an item with up/down keys and press enter to select it the form is being submitted. How can I fix this?


Some code:

<asp:SqlDataSource ID="sdsCountries" runat="server" ConnectionString="cs"
SelectCommand="SELECT CountryID, Title FROM Countries"/>
<asp:DropDownList ID="ddlCountries" runat="server" DataSourceID="sdsCountries"
DataValueField="CountryID" DataTextField="Title" AutoPostBack="True"

Html - Pressing ENTER In A Textbox And Form Submits?

Sep 4, 2010

it's a simple question and yet i couldn't figure how this works.I created an aspx page without any master page.Put one text box on the form.then use Internet Explorer 8 and visit that page.typed something and hit ENTER on the keyboard. The form submits (judging by that page being refreshed). I didn't even put any buttons on the form. Just the textbox. What triggers the postback?I further added one < asp:Button > next to the textbox and wired the button to see if it's been clicked.

i repeat the same thing, typed something in the textbox and hit ENTER on the keyboard. The form submitted but the button wasn't click. What's happening? How the postback is triggered if it's not from the button?
This is happening in Mozila Firefox too except that when i added a button on the page, the button will be hit when ENTER on the keyboard is pressed.Can anyone shed some light as to why the button i added didn't respond to the ENTER on the keyboard in IE8?

Web Forms :: Enter Key No Longer Submits After Adding LoginImageUrl To Asp:LoginStatus?

Jan 7, 2010

I have a login page inside of a master page. On the left-hand side of the master page in side a navigation menu, there is a search box with a button that is set to be the default submit button via code when text has been entered into the search text box.


ABOVE the search box is a ASP:LoginStatus control that when the user clicks "Login" it takes you to a login.aspx page which contains a ASP:Login control inside the same master page. Without setting the LoginImageUrl and LogoutImageUrl properties of the ASP:LoginStatus, the login/logout appears as text. And the enter button works when a user enters text into the search box (submits info to search service and takes user to search results) OR if the user enters their user name and password into the Login control and hits enter (logs in and redirects user based upon role). Everything works fine. Once I set the loginImageUrl and LogoutImageUrl properties of the ASP:LoginStatus though, the enter key no longer submits anything. It will just postback the page.

I'm guessing that adding an image to those properties cause the loginstatus to take the default behavior of a button. How do I prevent it from breaking the behavior of the enter key on everything else?

Dropdownlist Selection Changing - Whole Page Doesn't Postback

Aug 6, 2013

I have two dropdownlists on my page that are related to one another, and are built dynamically. I did not write the original code, but I believe it is using AJAX so the whole page doesn't postback when the ddl selection changes. The first ddl is Status and the second is ContractType. Here is the code for the event handler:

protected void Status_SelectedIndexChanged(object sender, EventArgs e)
DropDownList status = (DropDownList)sender;
string selectedStatusId = status.SelectedItem.Value;

[Code] ....

Here is some of my debugging info:

? view.Count
? view.Table.Rows.Count
? contractTypeDropDown.SelectedValue

[Code] .....

I commented out the event handler since this snapshot, just to see what would happen, but when I was hitting it you can see what ex.Message was. I don't understand why it says the SelectedValue is invalid when I see the selected value is "E " and that is one of the four items in the ddl.

Web Forms :: Redirect To Any Website Page On DropDownList Selection

Dec 6, 2013

Article located here: [URL] ... Code is simple, straightforward (especially with the stored procedure piece). I customized the code a bit to fit my requirement and it works great.

I would like to know if you can give me a hint on how to do the following:

My dropdownlist has 10 listitems. 7/10 works fine because they populate data from the db. However, there are 3 listitems that link to external sites and they have nothing to do with the db.

I have something in mind but I am not sure if it works or not. What I have in mind is I need to write some script:

In the web page, I need to use SelectedIndexChanged even

In the code-behind, I need to write something like this:

If listitem value = 'yahoo'  then ' else if listitem value = 'google'  then ' else URL

State Management :: Viewstate And Dropdownlist / Initial Selection Is Lost Each Time The Page Refreshes

Jan 13, 2011

I have a simple search page with a drop down list that I would like the value to persist on refresh..basically the user will select their location from the dropdownlist and this will be used to populate a gridview. After this the page is set to refresh at a set interval and use the same location data initially selected by the user. However the initial selection is lost each time the page refreshes.

p.s system is to old for ajax!

<meta http-equiv="Refresh" content="300" />
<script runat="server">
Dim connectionString As String = ConfigurationManager.ConnectionStrings("****").ConnectionString
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs)
If Not IsPostBack Then
Dim conn As SqlConnection
conn = New SqlConnection(connectionString)
Dim Locationcommandtext As String
Locationcommandtext = "SELECT * FROM [Location] ORDER BY [Location]"
Dim loccomm As SqlCommand
loccomm = New SqlCommand(Locationcommandtext, conn)
Dim reader As SqlDataReader
reader = loccomm.ExecuteReader()
Locations.DataSource = reader
Locations.DataValueField = "LocationID"
Locations.DataTextField = "Location"
Catch ex As SqlException
Response.Write("SQL Error:
" & ex.ToString())
End Try
'"Viewstate should kick in here"
End If
End Sub

Using Master Page Submits Null Fields To Database

Apr 6, 2010

Have created a Webform based on a master page.The code executes OK and sends data to the database, but inserts null values for all entries except the GetDate.

If I use exactly the same code in a new webform which isn't based on the master page, it inserts everything correctly.Here is a snippet from the form which uses the master page: -

<%@ Page Title="" Language="C#" MasterPageFile="~/SpeedDateMasterPage.master" %>

VS 2008 Dropdownlist Selection Disables / Enables Another Dropdownlist

Aug 1, 2013

I have a dropdownlist on my page with dates such as 1/1/2013, 2/1/2013, etc.

Then there is a second ddl.

If the date in ddl #1 is before 1/10/2013 I want to enable ddl #2.
If the date in ddl #1 is on or after 1/10/2013 I want to either disable ddl #2 or hide it (whichever's easier).

Disabling ddl #2 based on the selected date is a new requirement so I am enhancing the existing code. Obviously I want to do this without a postback, but I don't know what is the best way. I am trying to understand what an AsyncPostBackTrigger is because this is the existing code:

<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<asp:dropdownlist id="EffectiveDateDropDown" runat="server"></asp:dropdownlist>
<asp:AsyncPostBackTrigger ControlID="QuoteType"
EventName="SelectedIndexChanged" />

It wants to do something when the selected index is changed? This exists in the code-behind, but I set a breakpoint and never hit it:

protected void QuoteType_SelectedIndexChanged(object sender, EventArgs e)
catch (Exception err)

Security :: Asp:LoginStatus Logout Link Submits Form On The Page

May 5, 2010

I am using the SQL Membership provider to handle authentication. On one particular page the main function is the registration of an asset. You have to log in first. No problem. I also have required field validators on this registration form that work nicely. The problem is, if you log in, go to that page, then click the 'logout' button, it seems to submit the form (bypassing all my validation in the process)! I know I can't be the first person to come across this, so I'm guessing I've set something up wrong somewhere.

How To Call UserControl Javascript When Parent Page Submits To Server

Sep 8, 2010

I have an usercontrol located on on my aspx page. In the usercontrol there is a javascript function that I would like to fire everytime the page that contains the usercontrol submits to the server. (directly before this happens) Ideally I prefer to not have to write any code in the parent to make this happen, but I am not sure what the usercontrol may be capable of at this time. Can the usercontrol know that the page is submitting to the server and fire the function before this happens? Is there some sort of event that takes place here?

How To Redirect Based On Selection Of DropDownList

Jul 26, 2010

I have a TextBox1 and a Search button in my application with this following code:
protected void Button1_Click(object sender, EventArgs e) {
Response.Redirect("~\searchpage.aspx?PatientNRIC=" + TextBox1.Text); }

Which means, if the user type ONLY IC NO:S1234567D, then when click it will show the patient detailview. So I now I'm doing almost the same thing but now I have a TextBox2 and a DropDownList1. Inside DropDownList1, I have "Name", "IC No", "Test_Date". So for an example, I type "S1234567D" in the textbox1, and I choose "IC No" in DropDownList1 it should redirect me to a page of the S1234567D's patient detailview. How could I do my code?

Web Forms :: Get A Dropdownlist Selection Cached And Used Later In An App?

Jan 11, 2011

I have a page that searches and displays records. Users enter a record number and then select the type of record to display from a dropdownlist control. They then edit some data on the page, and the app does some calculations based on the type of record that is selected from the drop down. How do i get to successfully pass the value from the dropdownlist to the method that does the calculation to ensure that the right formula is used? Here is the code that I currently have.


then the code behind to do the calculation looks like this...


After stepping through the code, i noticed that when it gets to the "foreach" block, the value selected by the ddlRecordType dropdownlist is always the default which is "select one" and not any of the other selections that might have been selected.How do I get this to work, so that it can maintain the value selected from the dropdown and used in the code behind?
