In HTML your output would be like this:
<INPUT TYPE='CHECKBOX' VALUE='1' ID='Name1'><LABEL FOR='Name1'>bilal khatri yousuf</LABEL><br/>
<INPUT TYPE='CHECKBOX' VALUE='2' ID='Name2'><LABEL FOR='Name2'>faheem chania ali</LABEL>
But I am not sure if this is what you want to know.
I wish I could believe there is an after life.

Get the text into a string , split it by space and get the first name.

Hi,
A really well written article, which I recommend you look at if you haven't at is Journey through the Javascript MVC Jungle[^].
Here's my dilemma. I want all the goodness of controllers, I want strongly typed views and model binding - basically all the best bits of MVC. However, even a fairly simple page will usually require some client side script for showing\hiding elements, confirmation boxes & all that funky stuff that users expect for todays interactive web pages. You normally end up with 'page specific script' which will be a number of event handlers and bindings, with no real structure as such.
Backbone, Knockout and many of the other frameworks mentioned in the article I linked address this problem, they allow you to create client side models and bring structure and cohesion to your client script. However, the way they are designed almost relegates MVC to a simple 'web API' to handle RESTful requests and respond with some JSON. You seem to end up moving logic that I believe should be in the 'server side controller' into a 'script controller', which I'm not really happy with.
I want a structured script representation of my Model, that wires up all by event handlers for my View and keeps everything in a logical order. But I still want model binding, data annotations, validation and logic in my controller, everything that should be handled by MVC.Net. I want the best of both in other words
I've read quite a bit on this subject, so I know there are many different options available to me - that's the very point of the link. I'm just interested how others developing in MVC are addressing this problem?
Most of the applications I'm working on at the moment are Line Of Business, but they can still have some fairly complex client side functionality. I'm not using any framework at the moment, I'm just namespacing my script and wrapping up some jQuery (i.e. Javascript modular pattern) ... it works, just not sure if it's the best way to be doing things.
Any thoughts?
Cheers

I'm using revealing module pattern and knockout
js file contains viewmodel something like this
var viewmodel = function (){
model = ko.mapping.fromJS([]),
init = function(initialData) {
model = initialData;
},
save = function(data, event) {
$.ajax({
});
},
delete = function(data, event) {
$.ajax({
});
};
return{
Init : init,
Save : save,
Delete : delete
};
};
view contains script to initialize viewModel and bindings
$(document).ready(function () {
viewmodel.Init(Model.toJSON());
ko.applyBindings(viewmodel);
});
Not sure if it's the best way but it works.

that's exactly right. .NET Model is converted into JSON object and passed on to the Init function. In the Init when we do something like this we get the exact representation of the .NET Model in a javascript object with all items as knockout observables which is nice for a two-way binding.
model = ko.mapping.fromJS(initialData);
or
model = ko.wrap.fromJS(initialData);

Hi all, I am trying to create textboxes dynamically and I came across a method that does mostly what I want while searching for a solution on line. The method below is what I've found
for(int i = 0; i<boxes; i++)
{
TextBox tb = new TextBox();
tb.Location = new System.Drawing.Point(40, 120 + i * 20);
tb.Name = "TextBoxName" + i.ToString();
tb.Size = new System.Drawing.Size(184,20);
tb.TabIndex = i + 2;
tb.Text = String.Empty;
panel1.Controls.Add(tb);
}
The problem with the above code snippet is that sending values placed inside of the created textboxes to a database is difficult because the textboxes all have the same name. If each textbox can be given a different name when it is created, it will be great. Any suggestion is greatly appreciated, thanks in advance

Would you please explain how all textboxes have same name. The loop clearly says that every textbox created has index associated with its name. First textbox name reads "TextBoxName1", second reads "TextBoxName2" and so on. Where is the issue you are facing?
Thanks & Regards,

why dont u provide id of the texbox:
tb.ID="txtBox" + i;
u just pick id for your any operation.It will be unique.
I have replied as much i understand your problem.

The problem u have is how to access the dynamically created textboxes, isn't it
ok
look, the code u had written actually creates a number of objects of type TextBox, and give every one a name that is 'TextBoxName1', 'TextBoxName2',.. etc
the problem here is how to access the objects created.
so, you must declare a generic dictionary of string and TextBox on the class level, means
Dictionary<string,TextBox> AllTextBoxes = new
Dictionary<string,TextBox> ();
this code will be in the class level not inside any methods.
the second step is to add a line inside the loop to add items to this dictionary, each of them consists of a key and a value, the key is the name of textbox, while the value is the textbox object created in each loop, this line will be at the end of loop,
AllTextBoxes.Items.Add("TextBoxName" + i.ToString(), tb);
now, u can access any textboxe through the dictionary when giving the name of textbox like this
string aaa = AllTextBoxes["TextBoxName1"].Text;
I hope this is usefull

For starter I don't think that code you posted above is for asp.net. html TextBox control don't have size and location properties (this is controlled by css class and some css styles). Second, don't you think that placing in a loop with "i" index and appending this index name, give each text box unique name?

Take a look at the properties IsNamingContainer - then tweak how you're adding the text boxes, then FindControl will more than likely look attractive
C# has already designed away most of the tedium of C++.

Did you debug and see the execution flow?
Just a thought, may be the URL provides is not properly formed/resolved.
|
|

You have to build and return a json formated string back to the jquery in the client side, and in the jquery, you have to parse the json response(data.d); and populate the textbox.
So your sending to the web service, and perhaps the client is receiving, debug your web service, and test the return value in a json validator before fixing the client side.

I bet this service is returning xml.
Read about json enabled wcf service and use that for this.
