Web Forms :: Dropdownlist Selection Changes To First Item On Postback

Oct 19, 2010

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.

Web Forms :: List Box Jumps Back To Top On Selection Of Item (Postback)

May 5, 2010

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.

C# - Changing Dropdownlist Selection Causes Full Postback?

May 6, 2010

I have a search page with a TextBox that allows someone to type in a search term and press enter. (Which fires TextChanged). I have a DropDownList that specifies the kind of search that will be performed. It is defined in the markup as follows:

<asp:DropDownList ID="lstSearchType" runat="server" AutoPostBack="false">
<asp:ListItem Value="0">Last, First</asp:ListItem>
<asp:ListItem Value="1">Last</asp:ListItem>
<asp:ListItem Value="2">First</asp:ListItem>
<asp:ListItem Value="3">Liberty ID</asp:ListItem>
<asp:ListItem Value="4">E-mail</asp:ListItem>
<asp:ListItem Value="5">Telephone</asp:ListItem>
<asp:ListItem Value="6">Birthday (exact m/d/yyyy)</asp:ListItem>
<asp:ListItem Value="7">SSN (exact ###-##-####)</asp:ListItem>
<asp:ListItem Value="8">Address</asp:ListItem>
</asp:DropDownList>

As you can see, AutoPostBack is set to false, and there is no event hookup.

Pressing enter fires the OnTextChanged event for the TextBox, which performs a search and updates a GridView in an UpdatePanel. This UpdatePanel has its UpdateMode set to conditional and has one trigger: the TextChanged event of the search TextBox.

It's very simple.

And it works beautifully, almost.

Whenever I change the search type, the very next search does a full postback. All subsequent searches do partial postbacks (as desired) unless I change the search type again.

There is one exception to this rule: if I load the page and immediately change the search type, it doesn't do a full postback. So the first change of the DropDownList before any postback (full or partial) does not trigger a full postback.

Full Disclosure: I'm doing a lot of JavaScript to change the appearance of the gridview during async requests. I don't detail it here because it seems unrelated. This problem only occurs when a DropDownList with no JavaScript wired up is changed.

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:

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

[Code] ....

Here is some of my debugging info:

? view.Count
4
? view.Table.Rows.Count
20
? 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.

Forms Data Controls :: Dropdownlist Postback Always Select First Item?

Mar 24, 2010

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?

Jquery - Add Dropdownlist Item From JavaScript Causes Page Postback Error

Feb 17, 2011

all elements are in an updatepanel. click on a list of <tr> to fire a JavaScript function to add new <option> to the asp dropdownlist. But, when I click on other buttons to callback to the server, I get an error message:

Uncaught
Sys.WebForms.PageRequestManagerServerErrorException:
Sys.WebForms.PageRequestManagerServerErrorException:
Invalid postback or callback argument.
Event validation is enabled using

in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation. I understand the problem. I need to let server side know the change of the dropdownlist before any other postback. Set validation as false won't work in this case, the dropdown will lose the new item anyway. I did some researches, and the possible solutions:

1)Using ViewState? Request Form? could anyone give an example?

2)Add dropdownlist item in server side. But I want to make the whole tr row clickable to fire the event. Could I click on tr and fire eg. its first child linkbutton or a linkbutton in somewhere else.

3)I've tried Jquery.ajax and webmethod , it can fire server event but since all method are static (shared) , it doesn't allow me to edit the downdownlist instance.

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:

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

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:

Code:
protected void QuoteType_SelectedIndexChanged(object sender, EventArgs e)
{
try
{
}
catch (Exception err)
{
this.PublishError(err);
}
}

MVC :: DropDownList Can Either Select Item OR Save Selected Item Back To Controller?

Jul 7, 2010

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
