Need advice - Designing ASP application

Boipelo3-Aug-13 5:14

3-Aug-13 5:14

I need an advice regarding the following: No codes

Requirement:
Design a website, with the whole content updatable. I have been given the design, and they want it to look exactly as is – no APS controls. It looks more static. Think Wikipedia without the edit links. – They also don’t want to see the login buttons or link on the website.
The only functionality will be the contact us form.

My Thinking
I will have two identical applications, one for administration and another for the public.
Why Two? Use friendliness: The administrators will have the same look as the public website so they know where to update the website. Think Wikipedia edit links.

Tools:
KnockoutJS- I will learn it in the next 5 days – I am clueless with it, and have 3 weeks to complete the website. I choose it because I will be able to bind the content to the HTML tags, remember, no ASP control on the public Website. I will only be using Knockout for displaying and nothing else.

MVVC – When going through lots of article, I noted that knowledge of MVVC is a required to work with KnockoutJS. I am also clueless in this field. Also to be learnt in the next 5 days.

Would you be so kindly to advise if you think I am taking a proper path and if possible advise on what you would have done without adding tools for me to learn. I do like to learn but not now , except for KnockoutJS and MVVC – I am also maintaining other applications, I will actually be learning during the night.

Current skill/knowledge: C#, ASP.Net, Ajax, SQL, XML, Oracle, HTML, CSS, DevEpress

Thanking you in advance.

I remain joe!

Am I talking to myself? I think I do.

Planning to study things without having full details about them is not wise.

My expectation about was to be achieved with knockoutjs was wrong, I thought it can connect to SQL and bind the data without additional tools. After going through the book (Knockoutjs_Succinctly), I leant that it’s mainly used for binding data. I know have to lean Json for data manipulation.

So, I ask; will Json be able to communicate with SQL Server?
I know nothing about, I will learn in the next few day. Basic knockout took me a day, so I don’t expect Json to go beyond 3 days.

Advice welcome the path I am talking is welcomed.

Thanking you in advance.

I remain joe!

JSON won't talk to SQL for you. JSON isn't a language it is just a serialized JavaScript object. If you're using Knockout you will need a webservice you can call (coded in something like .NET perhaps) that will return a JSON object.

Thanks for the explanation, it helped a lot. I researched a bit following your comment/explanation and now know what to do. I still have to study JSON to at least intermediate level, for now.

Thanks once more, much appreciated.

Panels or div elements are hard to align, until you understand CSS, and Float. Clear, Display, Block, Inline

If you position 3 div's in a row, then the total width of the 3 div's must not exceed the width of the parent container, or else it will block, block meaning the 3rd div will position down 1 row. Block is the term used in the CSS Display, in which block and inline are valid options.

If you want to stack 3 div's on top of each other, block, then you can use display: block and they will stack in a column.

If you want to create a row of 3 div's, you have to float the 2nd div, and 3rd div to get it to align to the first div.
float: left; display: inline;

It's probably easier to hand assign the CSS for each panel until you get it right, rather that using a class from a CSS File. Then you can get a better idea of how the CSS works for div's.

There use to be a really good tutorial on div alignment but I could not find it. It had picture examples of how to align div elements, or aka panel control in asp.net

Hello,
I need a tool that can be used to write mathematical, chemistry and physics symbols or fomular in my ASP.NET application. The scenario is that, my clients will be solving mathematical, chemistry or physics questions from the ASP.NET application and they will need to write the formular using a tool build in my ASP.NET application to solve any question(from algebra, trigonometry, set theory e.t.c...) in a way they think the answer to the question should be. I am stuck here as I do not know the kind of tool that can be used to accomplish this.

I will be glad to hear a favourable reply on this forum.

Issue with event keyword. Some browser are not support only "event" keyword. So try to use event called "onblur".

It's opposite of onfocus:

function getval() {

document.getElementById('<%=textbox2.ClientID %>').value = document.getElementById('<%=textbox1.ClientID %>').value;
}
