Put an onchange event on each textbox that calls a JS function. In the function, check if all 3 textboxes have numbers in them. If so, add them and put the result into the 4th textbox.

I have data in a SqlServer table and I want to Select the data into a gridview or something like that and perform a calculation on the data.
I want to have a button that will carry out a calulation on all the records displayed and save the total for each record after the calculation to a field in the DB table containing the records.
Anyone any ideas on best way to do this?

There is any reason NOT to do the calculations inside SQL? SQL is pretty good with calculations...

Alex: Fix it? How you gonna fix this?
Skipper: Grit, spit and a whole lotta duct tape.

In the button click, call a stored procedure that does the calculation and updates the data and then refresh your grid.

I have a system which has an asp.net front end and a SQL Server DB.
I get a file in the form of an excel spreadsheet every few weeks that contains a number of fields. I want to load it into the DB and the appropriate fields in the excel spreadsheet would go into the corresponding field in the DB tables.
Anyone know how to do this?

Try one of the following libraries:
Avoid "office interop" at all costs:
Microsoft does not currently recommend, and does not support, Automation of Microsoft Office applications from any unattended, non-interactive client application or component (including ASP, ASP.NET, DCOM, and NT Services), because Office may exhibit unstable behavior and/or deadlock when Office is run in this environment.

You could also use SSIS or even create a job to do the work and schedule it in SQL.

i have requirement of running my application over wan hence i used a fixed ip addres in browser i.e(fixed ipaddress//hostmachineip address//mk(virtual directory)/xyz.aspx(cs file))...and m getting follwing error while accessing my app over wan
Runtime Error
Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.
Details: To enable the details of this specific error message to be viewable on remote machines, please create a <customerrors> tag within a "web.config" configuration file located in the root directory of the current web application. This <customerrors> tag should then have its "mode" attribute set to "Off".
<configuration>
<system.web>
<customerrors mode="Off">
Notes: The current error page you are seeing can be replaced by a custom error page by modifying the "defaultRedirect" attribute of the application's <customerrors> configuration tag to point to a custom error page URL.
<configuration>
<system.web>
<customerrors mode="RemoteOnly" defaultredirect="mycustompage.htm">

Did you convert your site to application in your IIS?
|
|
|
|
|
That message is telling you the real message is being hidden. Do what it says and turn custom messages off to see the real error message.
|
|
|
|
|
yes i did custoerrors mode =Off in web.config file but not result
|
|
|
|
|
Then the web config you think your site is using isn't the one that it *is* using so your site\virtual directory is probably misconfigured.
|
|
|
|
|
but its working fine in LAN but not WAN....hence how should i resolve this issue now..if not configured then it wouldnt have worked over lan ?

Check the application event log on the server. The error should be logged there.
We can't see your code, and we can't access your server. Without the error, we can't even begin to tell you what's wrong.

Thanks for the response... but when i checked event log on server then found an event called wpn connection failure which is just new to me...what is all about this?
|
|
|
|

That error is unlikely to be related to the problem.
It sounds like the request isn't reaching your server. It's probably a router or firewall configuration issue.

Thanks

For your site to be accessible via just the IP the site has to be mapped accordingly so that all requests for the IP go to your site (or all requests in general by leaving the "hostname" empty in the bindings). At the end of the day your site is wrongly configured, we can't access your IIS settings, we don't know how you've set it up. I'd spend some time learning how you configure sites and how IIS works, as just repeatedly saying that your site doesn't work is like phoning a mechanic and saying "My car doesn't work, what's wrong?"

That is, I don't want to instantiate a second form (or third or forth..) when I click a new row. I want the form already there, say form2, to show the data row from form1.
form1 has the gridview. Click one line and the textboxes on form 2 populate with the new row selected.
Is this possible?
Thanks!

I am following this tutorial: http://www.w3schools.com/aspnet/mvc_models.asp, to get data from SQL CE using Entity Framework. There doesn't seem to be much code. The tutorial is for MVC3 but my project is MVC4, but I think major steps should be same.
I created a SQL CE database, and a table with needed columns.
Added data to the table.
On the C# side I have
namespace MvcDemoApp.Models
{
public class Employee
{
public int EmployeeID { get; set; }
public string Name { get; set; }
public string Gender { get; set; }
public string City { get; set; }
}
public class EmployeeContext : DbContext
{
public DbSet<Employee> employees { get; set; }
}
}
And code in respective controller
public ActionResult Index()
{
var c = db.employees.ToList();
return View(c);
}
That sample is for movies database, I changed all relevant info to employees.
I added the connection string as in that tutorial too.
But when I navigate to the Index page of above controller, the empty list is returned. What did I miss?
It seems I gave correct meaning to table columns too (e.g. similar to Employee class properties)
PS. This is how the DB looks after I stop running the app

protected void btn_dwn_Click(object sender, EventArgs e)
{
string File = ListBox1.SelectedValue;
Response.ContentType = ContentType;
Response.AppendHeader("Content-Disposition", "attachment; filename=" + Path.GetFileName(File));
Response.End();
}
Now the files are saving in local, downloads folder. I don't want it to happen. I want it to automatically save in c:\ with new folder.....
This is my code...Could anyone help me..

I believe for security reasons you cannot do this otherwise what's to stop someone pushing a file to a client silently to the client's system folders?
Ergo the client takes over handling where to save it to instead.
