Jquery - Populating A Select List From An Autocomplete?
Sep 27, 2010
selecting a few items from a list of thousands. I have an autocomplete field that searches the db, and returns a name/id pair. This is working fine.
The next step is to preserve the selected IDs, and allow the user to remove some if needed. For this, I've been looking at using a select, and was hoping a UI something like that provided by this, but it doesn't work: it allows you to select items that already exist in the select, but doesn't work with a dynamically created select.
The final step is a traditional postback (using a submit button, this is in asp.net webforms) where I'll need to have access to the final list of IDs.

I am developing an MVC application. As part of the functionality I am using jQuery to invoke a server side Action method. This method returns an array of strings. I would like to display the list of strings in a select list using jQuery. e.g. I would like to see the following html:
<select name="CompleteAddress" onchange="Run()" id="CompleteAddress">
<option>22, Random Address</option>
<option>24, Random Address</option>
<option>26, Random Address</option>
</select>
The values "22 Random Address" etc... come from the Action method.
Currently, I am invoking the action method as follows:

I'm using jQuery AutoComplete Plugin in ASP.Net as outlined in the article below, so that as a user types in a .Net textbox they get a list of options to choose them. This works fine, but what I need to do now is call a server side function when the user has finished typing or has choosen a value, rather than the user having to submit the value by pressing a button.

I'm trying to progam a strongly typed "Create" view using MVC 3 and razor. I want the user to be able to select a customer from a dropdown list (I populated this from my database using ViewBag in the controller). When the user has selected a customer I want a separate dropdown list to generate a list of dogs belonging to that customer related by the customerID in the database. The create button on the form will then take both of these values along with the the other fields and save it to the database.

On my page I have textbox in which user enters value. When 3 values are entered the autocomplete panel shows.In the panel the names and surnames of all available people are shown bassed on the value user enters. Bellow each name and surname is picture of each "candidate". However images are stored on another server (using https "protection") and some people don't have picture.

I have this menu which has z-index of 600.I also use autocomplete, and I set the zIndex option to 700, I also tried setting the z-index in the css file, but no matter what i do, the ul list the autocomplete script generats always has z-index of 1.
this is what i see when i "inspect element" using chrome(the results ul):
[Code]....
no css alteration will help there, since its written into the style attribute of the ul element, and the zIndex option of autocomplete seems to do nothing also.for now, i can handle it by simply setting the z-index of the menu to 0, but thats a realy dirty workaround since i do want to control the z index of the autocomplete results ul.

I built a modal dialog using the ModalPopupExtender from the AjaxControlToolkit. In that dialog, I'm trying to use the jQuery Autocomplete feature on a textbox. The values for the autocompletion are fetched from a webservice.I can see that the webservice is returning a result set, and I can see that being picked up in the Autocomplete code. However, the list is not displayed to the user to pick from.I thought this might be a z-Index issue, so I specified 'z-index: 9999 !important;' in my stylesheet. But that doesn't make a difference.

I have 3 drop down boxes, created using the HTML select tag. On page load, the first box has a few names. Now, when I click on one of the names in the first box, some more names should appear in the second and when I click on a name in the second box, some more names should appear in the third box. How can I achieve this using AJAX? I have to use ASP.Net and MS SQL Server only. I'm a complete noob to AJAX and I've been educating myself about it, but nothing's working out. I've been looking for the code for close to a week. I looked up w3schools.com, but when I tried that code, it didn't work. Please help me out and please tell me step by step, the things required in order to make it work, and what goes where. I have a deadline that is fast approaching and am at my wit's end trying to make it work.

I am running into some additional difficulties with dropdown lists, and I'm hoping you can correct my thinking.
I have a table populated with items; ITEM_ID, ITEM_NAME, ITEM_COST.
Here is my code:
[Code]....
With this code I get this error: DataBinding: 'ITEM' does not contain a property with the name '2'.
If I remove the assignment of DataSource to c1, the dropdown generates this error: 'DropDownList3' has a SelectedValue which is invalid because it does not exist in the list of items.
Parameter name: value
How should I code this so that the user is presented with a list of ITEM_NAMES, and that the ITEM_ID is stored in the value field so I can use it when the selection event is fired? I know I could databind the source directly to the dropdown list, but I am trying to understand the behind the scenes working of a dropdown list object.

I have a Drop Down List that has some items in it, I have a switch set up that will clear and repopulate the drop down list from a sql server db depending on which item is chosen. When the list is repopulated from a database table I want to use an if statement to do something based on which item is chosen. I've tried to use an if statement but no matter what I try, the code checks the if statement for the original items in the drop down list, not the items that repopulated the drop down list.

I am trying to assign values I've gathered from a JSON feed to my own type, a class in which I have defined certain fields (properties) to put the JSON elements into, plus elements that are derived from a RegEx pattern matching process. This will then allow me to access the object using LINQ, as I am using a List to hold my objects. There is a foreach loop in my code that loops for each match that my RegEx method finds. I am only interested in the parts of the JSON feed where there is a match. So my own defined class is as such:
//simple field definition class
public class TwitterCollection
{
public string origURL { get; set; }
public string txtDesc { get; set; }
public string imgURL { get; set; }
public string userName { get; set; }
public string createdAt { get; set; }
}
And then I want to populate List in the RegEx Matches loop:
foreach (Match match in matches)
{
GroupCollection groups = match.Groups;
var tc = new List<TwitterCollection>()
{
origURL = groups[0].Value.ToString(),
txtDesc = res.text,
imgUrl = res.profile_image_url,
userName = res.from_user_id,
createdAt = res.created_at,
};
}
The code will then go on to extract and sort the results via Linq to Objects. But compiler won't actually let me create my var tc = new List<TwitterCollection>() because: 'System.Collections.Generic.List' does not contain a definition for 'origURL' ... even though I have defined it. It does not flag an error if I simply write new TwitterCollection but then how do I refer to this in my Linq expression later on??

I am populating a page with controls reading properties of a class using reflection. If the property type is 'String' I will add a text-box. If the property type is enum I am adding a dropdownlist. Now I have to populate the dropdown options with enums. How can this be done?
Both the enum definition class(Assignment) and the class(classOne) using which I am populating the page with controls are in the same Namespace(MySolution.Data). While looping through classOne properties when the property name is 'SkillLevel' I will have to go to assignment class get the members of enum SkillLevelEnum and populate the dropdown.
Same needs to be done for other dropdowns also.
My Code:
namespace MySolution.Data
{
public class classOne : MyAdapter
{
private string _Model;

I have a upload section on a user control
<div class="AttachQuote"><fieldset>
<legend>Quote(s)</legend>
<asp:Button ID="btnAttachQuote" UseSubmitBehavior="false" Text="Attach Quote" runat="server" />
<ol id="olUploadedFiles" style="list-style-type: decimal; padding-left: 30px;">
</ol></fieldset></div>
the btnAttachQuote is defined as
protected global::System.Web.UI.WebControls.Button btnAttachQuote;
can i do something simular to olUploadedFiles? there are alot of list options in webcontrols and i'm unsure how to use them. I would like to use a for loop to populate olUploadedFiles from a string array in my .cs. something like ...
int i = 0;
while (files[i].Length !=0)
{
olUploadedFiles.add (files[i]);//i'll substring the file names out
i++;
}
I'm using the same control for both the form submit and the status page(label only mode). I can load the rest of the info i just can't populate the dropdown from the codebehind.
