AJAX :: Create An Autocompleterextender Only From Javascript
May 6, 2010
I have a complex webform with a dynamic number of controls. I need to create some of them dinamically. There is no problem with asp.net validators, texbox, dropdownlists... but I can't find the way to do it with the autocompleterextender.
I am wondering if it is possible to create AJAX Toolkit control using JavaScript/JQuery or not. I know that I can create controls at server (at design or code-behind) and interact with its properties using JavaScript but I would rather want to initalize and create controls at client side using JavaScript/JQuery.
I'm working on an MVC application and I ran into a little snag.
I've got a form with the usual textboxes and dropdowns. I decided to use jquery ajax (GET) to load the dropdowns on load (State Names & Salutations).
No matter what I try, for example:
Code: <AcceptVerbs(HttpVerbs.Get)> _ Public Function ReturnSalutationDropdown() As ActionResult Dim dropdown As New DropDownList With {.TabIndex = 1, .DataTextField = "Value", _ .DataValueField = "Key", .ID = "ddl_coSalutation"} dropdown.DataTextField = "Value" dropdown.DataValueField = "key" dropdown.DataSource = AppEnumerations.BindToEnum(GetType(AppEnumerations.Salutation)) dropdown.DataBind() Dim sb As New StringBuilder Dim tw As New IO.StringWriter(sb) Dim hw As New HtmlTextWriter(tw) dropdown.RenderControl(hw) Return Content(sb.ToString) End Function
The ID of the dropdown ends up like: ctl00$MainContent$ddl_coSalutation
It doesn't matter if I use a stringbuilder and a loop to create a <select> with <option>'s, the ID always ends up like above.
Do I have to create a javascript function to create it instead?
I am trying to create a toolbar on top of my website to be used on an iphone. However, iframe is giving me considerable trouble in that it refuses to allow the page to scroll. Here's my code:

I have a search page that is used in multiple places with multiple 'themes' throughout my site. I have a few divs that can have their background color changed based on a radio button selection (whether they are enabled or not). I can do this just fine by changing the css class of the div on the fly with javascript.
However, these themes could potentially change, and the background color is grabbed from a database when the page is created. Right now I do this in the C# codebehind:
In the Javascript I need to change this color to make it look disabled, and when the user clicks back to this div I need to re-enable it by changing it back to its original color. But since I only knew this color in the code-behind, I don't know what it was in the Javascript.
So my thought was to create a css class in the resulting HTML page when the page is loaded with the background color I need. Then I could simply switch from the divEnabled and divDisabled class in the javascript. But I'm not exactly sure how to do that.
Is such an architecture possible? What datatypes can we use? I only exemplified enums because this is what i use right now, but they must be declared in the same file as they are used.
But how can I read each one of them in JavaScript because I want to populate the text boxes next time the user come to the form? I have tried this but it does not work:
var cookieName = ReadCookie("Name"); document.getElementById('txtName').value = cookieName;
Edit with Answer:
I used this code.
<script type="text/javascript"> function getCookie(c_name) { if (document.cookie.length>0) { c_start=document.cookie.indexOf(c_name + "="); if (c_start!=-1) { c_start=c_start + c_name.length+1; c_end=document.cookie.indexOf(";",c_start); if (c_end==-1) c_end=document.cookie.length; return unescape(document.cookie.substring(c_start,c_end)); } } return ""; } function checkCookie() { Name = getCookie('Name'); Surname = getCookie('Surname'); Email = getCookie('Email'); Company = getCookie('Company'); Title = getCookie('Title'); if (Email!=null && Email!="") { //Populate the text boxes. document.FormName.txtName.value = Name; document.FormName.txtSurname.value = Surname; document.FormName.txtEmail.value = Email; document.FormName.txtCompany.value = Company; document.FormName.txtjob.value = Title; } } </script>
And called the checkCookie() function like so from the window.onload
I want to create custom control (let's name it DesignPanel) that will allow user to design his own webpage structure that would be stored in a sitemap file. This Design Panel will have child controls inside ( SiteElement). User will build page strcture by connect Site Elements, customize them ( like change name) and add new ones.
This last point is main issue for me. Should I add those Site Element controls dynamically like DesignPanel.Controls.Add(new SiteElement()) in UpdatePanel control or there is better approach ( adding them to DOM structure by javascript, something diffrent)?
Is there any way to create a RequiredFieldValidator directly from JavaScript and assing the validation to a new created textbox, also created from javascript? I know how to create a new textbox or input control, but the RequiredFieldValidator is giving me problems.
With in Value another array of objects. So here we know that Key A is found on index 0. To get A value I use if(list[i].Key=='A'){...} . I would like to directly navigate to Key with value A without using a loop first to find it, so I thought of a index mechanism for this.

I am using the following code to create calendar controls on textboxes that have been dynamically created using cloneNode. The problem is that in IE it seems to add the behavior twice to the textbox causing it not to work. Is there a way that I can remove this behavior before it is added in ie only to prevent it from being added again? This works perfectly in firefox
Im using asp.net c# (webforms) I want to add a back button to my page. (you land on this page if you incorrectly fill in a form). if javascript is enabled i want to go back via javascript, but if it is disabled i'll just do a response.redirect("~/home.aspx"). how can i implement this? is it 2 buttons? how can i hide the other in the 2 different states if so.
I need to create a table with just 1 column containing times (starting from 4hrs) which increase in increments of 10 seconds for each row. So it needs to look something like this:
This will obviously take a long long time to hard code so I'm looking to create it dynamically. Based on what i'm currently trying to learn I'd like to be able to do this using jquery or asp.net (vb) but anything will do as long as it works!
In your opinion, what's the best way to create the server side to a pure Javascript application with ASP.NET? WCF rendering JSON? IHttpHandler? Update Like GMail, that runs in the browser (with a lot of Javascript) and submit and receive data with Ajax, for example.
what regular expression should i use to validate cricket overs in textbox. like it can be 5.1, 5.2,5.3,5.4,5.5 but it should not contain fraction value greater than .5 ,also the values should be numeric only (float and int)
For enterprise intranet web application, is there any way to create a desktop shortcut of web application on user's desktop? I'm looking for functionality similar to Google Gears, but without installing Google Gears. I'm looking to give user's a link on web application that says "Click here to install desktop shortcut", when they click on it, a desktop shortcut is installed with the custom icon for our application. Is there a way to do it using javascript or any other client side technologies? I don't want to run any exe on user's machines. Even though it's intranet, I have to jump through lot of corporate hoops, compliance approvals, etc to run exe on their machine. We are trying to avoid that, due to time constraints. User machines are windows XP with IE6 installed. They may all upgrade within next year's time to Windows 7 with IE8. Intranet web application in question is developed using asp.net 3.5, c#.
