Jquery Tab Selection On Postback?
Jun 25, 2010
I have an asp.net page with some JQuery tabs. Everything works ok.I added a dropdownlist in one of the tabs, that causes a postback. After the postback I want the same tab to be selected.I initialize the tabs as:
<script type="text/javascript">
$(document).ready(function() {
var $myTabs = $(".tabsDiv").tabs();
</script>
Then, on the PageLoad event, I inject a script to select the tab:
Page.ClientScript.RegisterClientScriptBlock(this.GetType(), "TabSelect", "$myTabs.tabs('select', 1);", true);
For some reason this doesn't work. The script is running but the tabs are not selected.Is it because the RegisterClientScriptBlock places the script in the bottom of the page and, for some reason, it runs too late?

Platform: ASP.Net 2.0 I have multiple checkboxlist controls on a webpage. Along with that i have the same number of buttons on that page. Initially all the checkboxlist controls are hidden. When user clicks on a button, corresponding checkboxlist controls gets visible making others hidden and allows user to select the options.
On postback, if user clicks on the same button again, the corresponding checkboxlist gets visible but the item selection is not retained. However, this happens only in IE. This works fine in FireFox. I am using JQuery to toggle the visibility of checkboxlist.I guess the problem is because i am toggling the visibility of checkboxlist which IE doesnt seem to like. What is the solution to this problem?

If I have a list of radiobuttons like this:

, when submitting the form and return the untyped View again, the selection is lost. What is the best practise to overcome this in MVC?
My submit-action looks like this as I am also passing an uploaded file...

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.

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 put a updateprogress into a webpage where selection from the dropdownlist causes postback. Works out well except that on the first postback, the gif image shows on the leftside rather than on the center. On succeeding postback, it will show on the centre where I intend it to be. Below is my code:

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.

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.

This is likely a n00b question, but I can't seem to find any info on how to solve it. Here's the scenario:
I have a Textbox and a RadioButtonList in an UpdatePanel, both with AutoPostBack turned on (they need to be, can't turn it off on the text box))
The user enters some text in to the textbox, then clicks one of the Items in the radio button list.
Because the textbox post back is executing, the radio button is losing the value that the user selected.
How can I workaround this?

JQuery supports a syntax of $("span[id$='Label1']") to allow selection of ASP.NET INamingContainer generated ID's that have been prefixed with "ct100$...".
We are using Selenium and are looking for a similar way to select elements, ignoring the prefixes that ASP.NET generates.

I have a page with a Search button, a gridview and a listview. When the Search button is clicked, the gridview fills up with a resultset and has a 'detail' linkbutton on each row. When the user clicks on the detail link, the listview below the gridview fills up with details related to the selected gridview row. My customers have asked if when they click on the gridview row, it becomes highlighted, and remains highlighted while they are working on the detail in the listview. So, I need to highlight the row when clicked, remove the highlight when a new row is clicked (as well as highlight the new row), and remove highlighting when the Search button is clicked. The highlight needs to remain over postback since there could be a full-page postback.
I'm thinking JQuery is the way to go but I am a JQuery novice and so would need a code sample.

Imagine you have this HTML layout:
<div id="msg"></div><br />
<div id="submitButton">
<input type="submit" value="OK" style="width:50px" onclick="$('div.subtleMsg').hide(); return false;" />
</div>
I know how to manipulate the contents of <div id="msg"> any way I wish but I'm wondering if it's possible, IN THE SAME LINE OF JQUERY CODE, to also manipulate <div id="submitButton">.
Everything has to be combined into one long jQuery string because I'm passing it from the server-side code as a script.

I had a simple working (ASP.NET) Scenario here: 3 asp:RadioButtons that each have OnCheckedChanged event that will update an asp:gridview. But now, I want to put some description for each radiobutton selection,and I thought it would be a good idea to embed them in JQuery UI Tabs like the following :
<div id="tabs">
<ul>
<li><a href="#tabs-1">
<asp:RadioButton ID="RadioButton1" runat="server" Text="option1" Checked="True"
AutoPostBack="True" OnCheckedChanged="RadioButton_CheckedChanged" /> </a></li>
<li><a href="#tabs-2">
<asp:RadioButton ID="RadioButton2" runat="server" Text="option2"
AutoPostBack="True" OnCheckedChanged="RadioButton_CheckedChanged" /></a></li>
<li><a href="#tabs-3">
<asp:RadioButton ID="RadioButton3" runat="server" Text="option3"
AutoPostBack="True" OnCheckedChanged="RadioButton_CheckedChanged" /></a></li>
</ul>
<div id="tabs-1"> <p> content1</p> </div>
<div id="tabs-2"> <p> content2</p> </div>
<div id="tabs-3"> <p> content3</p> </div>
</div>
and the jquery is
<script type="text/javascript">
$(function() {
$("#tabs").tabs();
});
</script>
I want the corresponding radiobuttons for each tabs be selected after switching to that tab (by clicking anywhere inside that tab) I don't know how to that probably by JQuery or JavaScript
Generated HTML source :
<div id="tabs" class="ui-tabs ui-widget ui-widget-content ui-corner-all">
<ul class="ui-tabs-nav ui-helper-reset ui-helper-clearfix ui-widget-header ui-corner-all">
<li class="ui-state-default ui-corner-top ui-tabs-selected ui-state-active"><a href="#tabs-1">
<input type="radio" checked="checked" value="RadioButtonCart" name="ctl00$ContentPlaceHolder1$g2" id="ctl00_ContentPlaceHolder1_RadioButtonCart"/><label for="ctl00_ContentPlaceHolder1_RadioButtonCart">option1</label></a></li>
<li class="ui-state-default ui-corner-top"><a href="#tabs-2">
<span style="color: Green;"><input type="radio" onclick="javascript:setTimeout('__doPostBack('ctl00$ContentPlaceHolder1$RadioButtonShetab','')', 0)" value="RadioButtonShetab" name="ctl00$ContentPlaceHolder1$g2" id="ctl00_ContentPlaceHolder1_RadioButtonShetab"/><label for="ctl00_ContentPlaceHolder1_RadioButtonShetab">option2</label></span></a></li>
<li class="ui-state-default ui-corner-top"><a href="#tabs-3">
<input type="radio" onclick="javascript:setTimeout('__doPostBack('ctl00$ContentPlaceHolder1$RadioButtonFish','')', 0)" value="RadioButtonFish" name="ctl00$ContentPlaceHolder1$g2" id="ctl00_ContentPlaceHolder1_RadioButtonFish"/><label for="ctl00_ContentPlaceHolder1_RadioButtonFish">option3</label></a></li>
</ul>
<div id="tabs-1" class="ui-tabs-panel ui-widget-content ui-corner-bottom">
<p> content1</p>
</div>
<div id="tabs-2" class="ui-tabs-panel ui-widget-content ui-corner-bottom ui-tabs-hide">
<p> content2 </p>
</div>
<div id="tabs-3" class="ui-tabs-panel ui-widget-content ui-corner-bottom ui-tabs-hide">
<p> content3 </p>
</div>
</div>
I solved 2 problems with adding ids to anchors like id="tabsA-1" and simulating the postback for
OnCheckedChanged="RadioButton_CheckedChanged" with $("#aspnetForm").submit();
<script type="text/javascript">
$(document).ready(function() {
$("#tabsA-1").click(function() {
$("#<%=RadioButtonCart.ClientID %>").attr("checked", "checked");
$("#aspnetForm").submit();
});
});
</script>
I just have to find a way to select the right tab after postback and my problem is solved.
<script type="text/javascript">
$(function() {
var $tabs = $("#tabs").tabs();
$tabs.tabs('select', '<%= selectedTabIndex %>');
});
</script>
which selectedTabIndex is a public string var in code_behind and i update its value in page_load. one funny problem was that the .tabs( 'select' , index ) in JQuery is not zero-based index of the tab as the official site said and it start from 1.

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;
