Web Forms :: Updation Not Happening Correctly - Stores Value As 0 In Database
Jan 15, 2012
I have a gridview with a select command.. When user selects a row.. I need to populate 4 dropdownlists with the values in gridview, dropdownlist which are also populated at page load event...
Though there is value in the dropdownlist when i try to update it selects 0th value.. Since while updating i use drptask.selectedvalue.tostring() since i am saving int values in database
It stores value as 0 in database..

Lets take an example of online ticket booking system. Many users could be booking the tickets at any point of time. a GridView displays the list of Allotted and Free seats If a seat gets booked, this information must get updated in all the opened pages in user's browser. User need not require to refresh the page to see if a seat is booked or not Should i put GridView in update panel and keep looking into the databse constantly ??? This could turn out to be a heavy work if databse is too large any other alternative?? or should i stick with the above approach....?

I am writing an application that collects Customer Complaints and stores them into a database. I want to keep it simple so that the Managers without much web knowledge can use it. This is how my Entry Form works. The Manager selects the name and id of the staff by choosing a location. This loads ids and names of the Staff in that location from the database. Then the Manager rates the complaint based on the severity and enters the comments. I was able to use Session objects to get all these values from the Entry page to the Confirmation page so the Managers can check again. This is where it gets tricky. If there is a correction they have to make by trying to go back to the Entry page, the values are lost (esp. Drop-down ones).

I need a basic system that uploads a file to the server and stores the details in a database, with the ability to add/ edit/ delete whats there.
Most of the solutions I've seen have been far to indepth. I'd like something very simple so I can pick it apart and modify it.

I have an ASP.NET web form application that on the server side I need to know the user's identity. I do not need to impersonate the user. I just need their username so I can update some records in a database correctly.When the request is processed I have the following line of code:
string userName = Request.LogonUserIdentity.Name;
if(true == string.IsNullOrEmpty(userName))
{
logger.logwarning("missing username");
}
else
{
logger.loginfo("update by {0}", userName);
}
In my development & QA environment this works perfectly - I see the userName in the log file and all of the database records have the lastModifiedBy field filled in correctly. However, when we go to production - userName is an empty string.

I have a login in my admin page. Now I want to log every login-try in my database. Normaly I have a Log-table with the adminID in a foreign key of the adminuser-table. Now, of course, when someone try to login with a username that doesn't exist, I haven't a ID and the foraign-key uses a crash in the write-attamp. Now whats the correct way to log a login-try when the username isn't correct and you haven't the correct id?
1) Add a second log-table for such things
or
2) Remove the foraign Key in the first log-table

I have two Listboxes side by side. First Listbox lists all employee. I have a button to move selected employee from Listbox 1 to Listbox 2. If i select multiple employee from ListBox 1 and click on a button to move to selected employee to ListBox 2, then only alternate selection is moved.
For example.
If ListBox 1 have employee listed as :
1. John
2. Micheal
3. Bryan
After moving to ListBox 2. It shows:
1. John
2. Bryan
My Code is:
protected void btnAdd_Click(object sender, EventArgs e)
{
for (int LItem = 0; LItem < this.ListBox1.Items.Count; LItem++)
{
if (this.ListBox1.Items[LItem].Selected)
{
this.ListBox1.Items[LItem].Selected = false;
this.ListBox2.Items.Add(this.ListBox1.Items[LItem]);
this.ListBox1.Items.Remove(this.ListBox1.Items[LItem]);
}
}
}
}

I have just used the Import and Export Wizard to copy my production SQL Server database, which uses Membership and Roles. I used the option to copy all the data from existing tables and views and did not modify the mapping in any way. Things do not seem to have gone well.....
My source database has a bunch of views with names like vw_aspnet_Applications,vw_aspnet_MembershipUsers, etc. The copy database has these listed as tables!I wondered if running aspnet_regsql.exe might fix things. I needed to run this anyway to create all the missing stored procedures for Membership, etc. However, it failed with the error:Setup failed.Exception:An error occurred during the execution of the SQL file 'InstallCommon.sql'. The SQL error number is 2714 and the SqlException message is: There is already an object named 'vw_aspnet_Applications' in the database.Creating the vw_aspnet_Applications view...I am a bit lost. All I want to do is to create a total clone of my production database for test purposes. Where do I go from here?

Trying to check if an insert of a new record into an SQL table is happening successfully. I can see that the insert is occuring OK but am not getting the verification to happen.
I'm a little new to C#, I'm thinking it may be in the syntax I'm using in my method in the .cs file line 45. Can't seem to fix it right though.

I have a C# DotNet application and an SP of SQL Server 2005. I had made changes to the SP. I found that the connection string of database in the web.config also is correct and it is pointing to the same database in the same server but after changing the SP and checking form front end I am not able to get the updated SP results. After changing the SP do we need to build dll of middle tier again? What all changes I need to make. When I run the SP individually it is giving correct updated results. i had done IISRESET also after chnaging the SP.

I am writing an ASP.NET application that suppose to connect to many different data stores and query them for data. Each data store contains different data: it can be an SQL DB, an XML file, or anything that can store data. The result is always an XML.
The remote data stores expose a WCF service (which I will also implement) that will allow me to query the data store and return the results.
My question is: how exactly should I implement the querying mechanism? Should I define my own query language?
