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.
View 3 RepliesI'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?

View 4 RepliesI 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:
string bgStyle = "background-color:" +theme.searchTextHeaderColor +";";
OwnerSearchHeader.Attributes.Add("style", bgStyle);
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.
As a test, I wanted to have an ASP.NET page rendered without the auto-generated javascript. Is this possible?
View 2 RepliesIs there a way to create a file of constants in JavaScript, which I can reference and then use?
What I am looking for is something like this:
Constants.js:
var Phones =
{
Nokia: 1,
Samsung: 2
}
Then, in another JavaScript file JS2.js access those values:
JS2.js:
alert(Phones.Nokia);
And then, in an aspx file that uses them, reference both of them, like:
<asp:ScriptReference Path="../js/JS2.js" />
<asp:ScriptReference Path="../js/Constants.js" />
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.
I know how to write/create cookies in JavaScript.
//Create the cookies
document.cookie = "Name=" + Name + ";expires=Friday, 31-Dec-2011 12:00:00 GMT; path=/";
document.cookie = "Surname=" + Surname + ";expires=Friday, 31-Dec-2011 12:00:00 GMT; path=/";
document.cookie = "Number=" + Number + ";expires=Friday, 31-Dec-2011 12:00:00 GMT; path=/";
document.cookie = "Email=" + Email + ";expires=Friday, 31-Dec-2011 12:00:00 GMT; path=/";
document.cookie = "Country=" + Country + ";expires=Friday, 31-Dec-2011 12:00:00 GMT; path=/";
document.cookie = "Company=" + Company + ";expires=Friday, 31-Dec-2011 12:00:00 GMT; path=/";
document.cookie = "Title=" + Job + ";expires=Friday, 31-Dec-2011 12:00:00 GMT; path=/";
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
<SCRIPT TYPE='text/javascript' LANGUAGE='JavaScript'><!-- //
window.onload = initPage;
function initPage()
{
checkCookie();
}
//-->

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.
View 6 Replies would like to speed up the a search using a for loop with a predefined/created index. For this object defined as :

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.

var $tstCalendar = $("#" + rawDateControlID);
$create(AjaxControlToolkit.CalendarBehavior, { "id": $tstCalendar.attr("id") + "cld" }, null, null, $get($tstCalendar.attr("id")));
Just for an example, if I have three controls on a Master page, I would usually declare a variable for a control like this.
var elem = document.getElemntId('<%=control1.ClientID %>');
var elem2 = document.getElemntId('<%=control2.ClientID %>');
var elem3 = document.getElemntId('<%=control3.ClientID %>');

View 2 RepliesI 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:

04hrs 00mins 10secs - 04hrs 00mins 19secs
04hrs 00mins 20secs - 04hrs 00mins 29secs
