have a button called "Confirm" which updates the datas entered in the screen. But the procress takes 1-2 minutes to update. I want to add a progress bar which automatically appears when the "confirm " button is clicked and automatically closes once the update is done.
View 19 RepliesI have SQL Server database entry LastCheck of datatype DateTime.
By first save it is no value, so it is NULL. LastCheck is configured to allow nulls.
What should I insert in my statement? How to initialise LastCheck in code? Should I convert DateTime to null?? I can't do just LastCheck = null, because it is from DateTime value.
Job job = new Job();
job.LastCheck = null;
cmd.CommandText = "INSERT INTO Jobs (LastCheck)"
+ " VALUES (@LastCheck)";
cmd.Parameters.Add(new SqlParameter("@LastCheck", job.LastCheck));

View 1 RepliesWhen I am creating a new form, I am inserting "RequestId" of particular form in Textbox as well as uploading multiple file (that comes in Gridview)and on save button click, those gridview multiple files with "RequestId" are saved in Database as below:
Id Request Id File Name
1 12 Abc.jpg
2 12 Xyz.doc
3 12 Pqr.png
4 11 Abc.xls
5 11 aa.jpg
NOTE: Auto increment of "Id" is true.
Now, I want that If I delete any file from the Gridview(which has all uploaded files), I want that file to be deleted from database table also.Currently on Deleting file from Gridview, files from "Folder" are deleted not from Database.
I got a table in a formview where i placed lots of textboxes and dropdownlists inside the table because I need these textboxes and dropdownlists on a background image.
the data on textboxes and dropdownlists that are inside the table is unable to be saved into the database when i pressed the "submit" button. Other textboxes and dropdownlists that are not inside the table work fine. Here are the HTML code for the table:
<asp:Table ID="Table1" runat="server" BackImageUrl="~/images/DRAWING.jpg">
I am using a bound gridview in ASP.NET 2.0. The gridview has the ability to edit/update and insert rows. One of the columns holds a number which represents a percentage. What I cannot figure out is how to ensure that all the rows in the gridview total 100% before being able to send the updates or newly inserted data to the database.
For example say there are 5 rows in the gridview, each row has 20% stored in the column so it adds up to 100% which is fine, the data is updated/inserted in the database. But say each row only had 15% totalling 75%, the user should not be able to send the updated/inserted data to the database until either they add a new row with a percentage of 25 or they edit the other rows for a cumulative total of 100%

View 2 RepliesI have a text field into which I'm saving order details, using LINQ to SQL.
Each order may have a different number of columns, depending on the type of order, so I thought I'd just create a single structure to take care of everything, and display details in tab delimited columns.
The text is created properly prior to saving to database:

However, when stored in the database, the spacing is no longer maintained.

I have a weird thing happening. I have two identical databases installed on one virtual machine but under two different instances of SQLServer. For some reason, periodically when saving from one it will save to the other instead. Using debug, I have verified that the connection string is correct and when the item saves, it still saves to the wrong database.I use session variable, and am of the belief that it might have something to do with it...and t hat when I go from one to the other it is still getting the connection string form the other for some reason.To make sure that it isn't a problem, I make sure that I completely close out one database before opening the other in a new IE window.I assume that when I completely close out an internet explorer window that it abandons all session states. Is that true?
