Javascript - Fire Method To Fill Detailsview Control From Jquery Autocomplete Input?

Mar 8, 2011

I have an input box for searching employee info (attached to a jquery autocomplete), and a box for employee number. The employee info queries multiple values (Lastname Firstname, Title, Clocknum) and returns them all as a string via the autocomplete. This is only if they dont know the clock number. The additional box is so they can search via clocknum as well.

Is there a way, to fire a method which populates a data control after clicking on or tabbing on the selected jquery autocomplete value?

C# - Javascript Added Input Control On .net Postback?

Jun 23, 2010

What I'm trying to achieve/plan, is whereby a page loads with a set of inputs, e.g. TextBox, Radio List etc. Taking TextBox as an example, there is a button for the user to "Add" another textbox to the page (in the same group), e.g. Member1, Member2, Member3 etc etc.

Two questions:

I could add these with Javascript, however the resultant "save" on postback would not get these inputs? If so, how? The form needs to work without Javascript as well, so postback to dad another control is fine, however if I click the "add" button again, it will only ever add one control.

protected void btnAdd_OnClick(object sender, EventArgs e)
holder.Controls.Add(new TextBox { ID = "txtControl1" });

Web Forms :: Validating Input In A Custom User Control Using Jquery Validation Plugin?

Jun 18, 2010

I have a custom user control with some input fields and a submit button. I need to validate the fields using the jquery validation plugin when the submit button is clicked. (The function of the submit button is to create another custom control which displays the data entered in the above mentioned control)

Bt as far as I knw, validation plugin works only with form validation ryt? And my custom control does not contain a form tag as I am using master pages. The custom control is present in one of the content pages and the master page already contains a form tag with a runat=server attribute. And I guess one page can contain only a single form tag with runat=server attrib ryt?

So how do I get it to work?

Jquery - User Control PageLoad Function Not Fire On Some Of Pages?

Mar 10, 2011

I'm working on an application.I had a problem with a user control I'd designed called LocationSelector. It worked great, but I couldn't use it within an ASP:UpdatePanel. I learned, by browsing SO, that I needed to put my in-line javascript in an external file and register it with ScriptManager so that there are no Response.Write calls in the Javascript.Next, I discovered that the control worked at first, but when I enclosed it within the ASP:UpdatePanel, it would stop functioning after the first AJAX postback. I read that to fix that, I needed to replace my $(document).ready call with function pageLoad() which is automatically executed with each page load.

Several of my pages in my application work fine (and I was really impressed with how well the framework seemed to drive the application). However, to my dismay, I discovered that my LocationSelector control no longer works at all on three of my pages. The HTML renders, but the pageLoad (which uses jQuery to bind events on control elements) does not fire.I verified this but putting alert('pageLoad'); as the first line of my pageLoad function. On the pages that work, I see the alert. On the pages that don't work, I never see the alert, even on the initial page load.What kind of problem could be causing the pageLoad function on my user control LocationSelector to execute on some pages, but not others?

Server Control - Avoid Adding Multiple Javascript

Jan 26, 2010

I created an Server control that derives from a LinkButton, and renders a small javascript function to the page. I want to use this control many times on the page, but just want the javascript to be rendered once on the page. On the other hand, I rather not manually add it in a js file, because i don't want to have a chance of forgetting to add the js file in the future.

Javascript - Adding Click Events To User Control?

Aug 28, 2010

I have a user control in an web application. The control outputs an html list that is customized based on the currently logged in user. The list items are generated from a database look up and the user control is formatted to appear as a drop down list in the page.

The control itself is simple and looks like this:

<%@ Control Language="VB" AutoEventWireup="false" CodeFile="item-lector.ascx.vb" Inherits="includes_usercontrols_item_selector" %>
<!--Item Selector-->
<div id="item-selector">

The code behind file dynamically fills the control's "output" property so the final markup appears as follows:

<div id="item-selector">
<h1>Item 1 - Item 1</h1>
<a href="#" class="changeItem itemArrow">Change item</a>
<ul id="changeItemMenu" class="dropDownMenu">
<li><a href="#">Item 1</a></li>
<li><a href="#">Item 2</a></li>
<li><a href="#">Item 3</a></li>
<li><a href="#">Item 4</a></li>
<li><a href="#">Item 5</a></li>
<li><a href="#">Item 6</a></li>
<li><a href="#">Item 7</a></li>
<li><a href="#">Item 8</a></li>
<li><a href="#">Item 9</a></li>
<li><a href="#">Item 10</a></li>

The ID and class properties are all necessary for formatting and other scripting. The control is meant to be used as a selector and the rest of the page should react to which item the user selects.

What I am trying to do is add click events to the list items. When the user clicks on one of the items in the list, I want to capture which item the user selects in the list (does this require a postback?) and do something with it in the code behind (< this is key).

I am more of a middle tier and db tier developer and UI development is not my strength so please consider me a newbie in that regard. I am not sure how to proceed or what to inject into the output string to enable this.

JQuery :: JQuery And Custom Attributes/ Find All Input Elements That Will Require Validation?

Jul 14, 2010

to directly get all elements in a form who contains a non html attribute ?

<input .... customAttribute="validateMe">

So I could find all input elements that will require validation.And use this in a loop to add validation to the input's found :

$('input').attr("customAttribute").val() == "validateMe"

I could also write every validation for each object separately, I have only a few elements who uses a required validation but it would be nice that I could do this in one shot instead of repeating the $("input").rules("add .....

I have added a jquey menu in my master page its working fine for those pages which are at the same level as master page.

But this menu isn't working at all for all of those page which aur in Editor's and Admin's folder. In these pages menu is displaying as simple html menu and unfortunately no jquery effect is shown on it.

MVC :: Html Helpers With Javascript... Include Javascript In Helper But Avoid Adding Javascript Twice?

Jun 22, 2009

So I love MVC and I love Html Extensions and now I want to push it a little further... If I wanted to create something like an Html Helper that creates a javascripty style Calendar (for the sake of example as I don't want a calendar :-) how could I wrapper the javascript into the helper so that the consumer of the helper does not have to include the javascript on the page. MOST IMPORTANTLY though I want to have many instances of my calendar on the same page, if I put the Javascript in the Html Helper it will get written out 3 times to the page which is no good, so I am wondering how to get around this.

Essentially I want to know whether I can access the page's DOM whilst the Html Helper is being run so that:1) I can add javascript script/src tags (did I mention I don't want to have inline javascript :-)2) I can query the DOM to check whether the required script has already been included by a previous call the same Html Helper.This may be a no-brainer for some mvc/asp guru out there, it may also be the case that you can't access the DOM at runtime via c#

Jquery - Access A Dynamically Created Control Through Javascript?

Sep 25, 2010

I've a JavaScript function in my page through which i make some elements in the page as 'JQuery UI droppable'.

function setDroppableTargets()

But the elements with the class cssDockZone is created dynamically upon user interaction. So in the code behind i create the control first and finally at the end i register a scriptblock which calls setDroppableTargets().

//set droppable targets ClientScript.RegisterClientScriptBlock(this.GetType(), "setDroppableTargets", "setDroppableTargets()", true);

But the javascript function is invoked before the controls are created eventhough i register the script at the end (after creating the controls) and i cross checked it by getting the elements with class name '.cssDockZone' and i getting it as 0.

Jquery - Javascript Not Firing When User Control Loads?

The Web site allows users to add user controls to a page (similar to adding a widget etc to a page like google widgets). But when the control is added the javascript does not fire, only if the page is refreshed will it fire the javascript. IF the next time the website is accessd and the controlis still there the javascript fires too.Do I need to use the RegisterClientScript method to register the call (setAutoTimer()) on the control load or OnPreRender event.In the User control I have this at the start of the ascx file:

Jquery - Creating A Custom Control In Javascript Properties And Methods?

Feb 23, 2011

As a starting point for creating custom controls, I would like to make a control that simply displays a number. If we imagine the .ascx file contains nothing except for a literal control, and the code behind sets that value to 1.

I then want to be able to do myControl.increment();
This will run some javascript that increases the value of the literal control.

I could inject a javascript into the page, such as pseudocode:

scriptything.register("function increment(x) { $('#myLiteral').increment(); });

or something, but that wouldn't be myControl.increment, that would just be increment(). More than one control on the page would screw it up.

C# - Calling WebMethod Via JQuery From JavaScript On ASCX, Needing Value Of Control?

Mar 3, 2011

I understand how to use jQuery to make an AJAX call to a WebMethod from a normal page, but I'm running into problems doing it from a UserControl (ASCX). Right now the biggest Issue I'm having is that the JavaScript for getting access to the groupDropDown control is not working. It seems that since this is a UserControl hosted within DotNetNuke, the ususal method of getting the CLientID is not working since it is nested down x number of levels. Here is what I have:


function validateEnrolledDate(src, args) {
var isValid;

I'm now just referencing a TextBox:<asp:TextBox ID="dealerId" runat="server" CssClass="theDealer" />

The Text in the Textbox is being set in Server Side code, and it is visible on screen.The alert message is "undefined", so something is still happening so that it is not getting the value of that textbox...

JQuery Undefined In Content Page When Using Master Pages Which Has JQuery Reference?

Jul 19, 2010

I have a nested master page. A parent master page, a child master page and a content page whose master page is the child master page. I have a reference to jQuery in the parent master page in the head section.<script type="text/javascript" src='<%#ResolveUrl("~/includes/jquery-1.4.2.min.js") %>' ></script> & Page.Header.DataBind(); in the OnLoad event.

I am using jQuery in all the pages including the master pages. However I am getting "Error: $().ready is not a function" in the content page. If I include jQuery reference in the content page it works. Question: If the reference to jQuery is in the master page head section, why aren't the content pages able to use jQuery? When I do view source, the script tag with jQuery is there and it works. The master pages and content page are merged during rendering and sent to the browser as a single html page so I am not sure when master pages are used, jQuery references break.


When I changed '$.ready(function()' to 'jQuery(document).ready(function($)' it worked! I am not loading any other javascript libraries and I am not using MS Ajax.
