To the best of my memory, JQuery does not really do math. For math, it's just pure Javascript.
There are Jquery testers, where you can test Jquery on the web, but I've never seen a builder. JQuery is pretty simple to implement, and the expressions are pretty short in length.
To store and expressionin sql, I would imagine you just store it as a varchar.
you can use jquery AJAX to write a JSON call to a web service, that will write to the database.

I Want to make SQL database primary key in Format. Something like that:
Primary key
A00001
A00002
A00003
....and so on.
Currently my primary key increase like that..
1
2
3....and so on.
I already tested with GUID but it is too long, complicated number & characters.
I don't want it. i want primary key in specific format.
how I have to do it.
how I have to generate insert sql command query in C#.
how I have to increment correctly.

This is a little off topic, but what is the problem with GUIDs? Unique keys and their values are of little relevance to me, as I usually am writing a program that takes care of them. I only rarely have any need to know a specific value at all, usually while debugging or while the program is not yet complete. In any case, it's never so bad that using GUIDs or any other format would make any difference. If GUIDs are so problematic for you, this might be an indicator that you should perhaps give the way you go about developing your application another thought or two.
And from the clouds a mighty voice spoke:
"Smile and be happy, for it could come worse!"
And I smiled and was happy
And it came worse.

Perhaps you mean something like this?
int x = 0;
string myKey = "A" + (x++).ToString("D5");
However, I would recommend (strongly) against generating a primary key outside of the database itself (such as in C#).
What type of database are you using? Microsoft SQL Server? This can be accomplished with a before-insert trigger within the database.

To stop this you can use Iframe to open your page.
But it will effect on your application performance.

ASP.NET is serverside. You will have to use javascript.
JQuery validation is a good plave to start

yes you can use regular expression ie) [^0-9].
|
|
|
|
|
You can use a MaskedEdit textbox and set the mask to only accept numbers. No validation or event handling needed.

Use a javascript/jquery function to achieve this:
1. HTML Mockup
<input id="txtNumbersOnly" runat="server" onkeypress="Validate($(this));" />
Above, "onkeypress" is the client-side keypress event. For more accuracy, you could replace "onkeypress" with "onkeyup" which only fires when you let go of a "key" (on your keyboard).
2. Javascript/jQuery
function Validate( sender )
{
if( parseInt( sender.val() ) )
{
}
else
{
alert( 'Sorry, only whole numbers are allowed in this input field. Please try again.' );
}
}

I have a Web Form and wish to scroll to a specific row when the DataGridView is populated. This is especially relevant when the user has clicked the Edit button having scrolled down the screen and I want to present the row to be edited, not the first row of the grid.
I have seen many solutions on how to achieve this in a Windows form; principally by using the DataGridView.FirstDisplayedScrollingIndex property.
But I am working in a ASP.net Web form environment where this property is not (obviously) available.
Can someone point me in the right direction of the equivalent C# program code for achieving this in a Web Form. Maybe there's some other "System." assembly I have to include upfront that will enable the constructs that I need.

You can du this by adding an anchor on each row and then link to mygrid.aspx#anchorname to scroll to that row.
Add an <a name="<%#Eval("id")%>"></a> and link to mygrid.aspx#123

What does the following parameter syntax mean?
@Html.DisplayFor(modelItem => item.Title)
Particularly, the => symbol?
The difficult we do right away...
...the impossible takes slightly longer.

OK, I see that's the Lambda syntax. I have to learn about that now.

I am working on a C# web form 2010 new application and I have a question about how to setup a validation control. In a dropdown list control I would only like to list the dates values that are in a certain date column in the table called 'master'. I would like a validation control to make certain the only dates allowed are in the 'receive date' column of the 'master' table. How would you set this up?
|
|
|
|
|
If the only allowable dates are in one column in a database table then populate the dropdown with those values. No validation necessary since the only values are those that are valid. I'm I missing something?

The problem is the Month and Year values have to be in separate dropdown lists accoding to the user. Also the month and year values do not end in December. All values can start in any month/year combination.

I am using MVC 2 on VS2010 and IIS 7. I created a portable area with some images embedded into it. I tried to create routing rule two ways at the time of portable area registeration. Following are the two ways I tried.
Method 1
context.MapRoute("ResourceRoute", "login/resource/{resourceName}",
new { controller = "EmbeddedResource", action = "Index" },
new string[] { "MvcContrib.PortableAreas" });
context.MapRoute(
"login",
"login/{controller}/{action}",
new { controller = "login", action = "index" });
RegisterAreaEmbeddedResources();
In this case I tried to access the image using Url.Resource()
Method 2
context.MapRoute(
"login",
"login/{controller}/{action}",
new { controller = "login", action = "index" });
RegisterDefaultRoutes(context);
RegisterAreaEmbeddedResources();
In this case I tried to access the image using Url.Content()
Following are scenarios where things are working fine.
1. When I run the application on my local development server (Ctrl + F5).
2. When run application after publishing it on my localhost.
3. When I run the application on different development server (Ctrl + F5), say on my friend's box.
But it does not render image (right now I have only images as static resource. No CSS or JS) if I publish on someone else's system, say localhost on my friend's box. Everything else is working fine except for the image rendering.
I have tried all possible means to get it rendered in the situation it is failing but all in vain. I need some help here. Anyone please?
Thank you in advance!

Have you taken a look at the html in the browser source, to verify it's correct when it doesn't work?
