I am creating a simple shopping cart using a datatable that is passed into a session object. I have a small mini cart that displays the total number of items in the cart as well as the running total - this is displayed in a web control. When the web control starts up I run a try/catch to see if the session object exists, if it doesn't I create the datatable for the cart and store it in the session. I then have a datalist control that contains all the information for my products including an "add to cart" button. When the page loads everything looks fine. If I click on an "add to cart" button nothing happens to the session information. If I click on it again, the session information updates - displaying only one item is in the cart and then counts up correctly there after. Additionally, after adding an item, if I select a different item in the list, the same issue occurs. I am not sure why this is happeing, if anyone can give me an idea I would appreciate it.
iam insert record using datable in gridivew,iam using session to hold the record,

dtempty.Columns.Add("storeid"); dtempty.Columns.Add("ratetypeid"); dtempty.Columns.Add("ratedesc"); dtempty.Columns.Add("slabs"); dtempty.Columns.Add("days"); dtempty.Columns.Add("rate"); dtempty.Columns.Add("contid"); dtempty.Columns.Add("continertype"); DataRow row; row = dtempty.NewRow(); row["ratetypeid"] = ddlratetype.SelectedValue; row["ratedesc"] = ddlratetype.SelectedItem.Text; row["slabs"] = ddlslabs.SelectedValue; &n
Hi! I'm creating an application that's supposed to first add a record to table1, and then get the ID from that record to use when adding a record to table2, to be able to associate these two records with eachother.
The user gets to type in some values that goes to table1, and some values that goes to table2, but before the insert statement for table2 is executed i need the ID from the recently added record in table1. Some dude told me to use a trigger for the autopopulate purpose, but does that really work when i also need to save some values that's user input, and when those values doesn't get saved in table1?
Are there any other way to do this or can i send values to a trigger? I'm new to triggers and stored procedures, i don't have any particular knowledge of this, any help is appreciated!

I am trying to simply extract an excel data from an uploaded file an put it into a datatable. In this case the excel file has 3 rows but when I fill the datatable I only see row count of 2.
I tried changing HDR:NO; to HDR:YES and vice versa, but no luck.
What am I doing wrong? (Note: the excel file cannot have a headerrow)
string connstr = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + pFilePath + ";Extended Properties=\"Excel 12.0;IMEX=1;HDR:NO;\"";
OleDbConnection conn = new OleDbConnection(connstr);
DataTable dtTables = conn.GetOleDbSchemaTable(System.Data.OleDb.OleDbSchemaGuid.Tables, null);
string strTablename = dtTables.Rows["TABLE_NAME"].ToString();
string strSQL = "SELECT * FROM [" + strTablename + "]";
OleDbCommand cmd = new OleDbCommand(strSQL, conn);
DataTable dt = new DataTable();
OleDbDataAdapter da = new OleDbDataAdapter(cmd);
//At this point row count=2 which doesn't make sense
I'm creating my first server control, and have it working where I can set up an enum and the user can set a property's choices, based off of that enum. But I'd like it to pull records from a database and populate the list of choices for the property from a database. This would allow me to add a new "Host System" to the database, and the other designers wouldn't have to get a new copy of the dll.

I have been using the following tutorial and had to convert the code to C# for my project, now i cant get the code to work, im getting red line under the word "in" in the UpdateRolesFromList, i tried to add a datasource on page load for the checkboxlist like so RoleList.DataSource = PopulateRoleList(User.Identity.Name.ToString());
and gives me error saying cannot implictly convert type 'void' to 'object'
What am i missing, that when i load the page or even do a search it never displays the checkbox list as it shows in the tutorial?
protected void Page_Load(object sender, EventArgs e)
public void PopulateRoleList(string userName)
string roleNames = null;
string roleName = null;
roleNames = Roles.GetAllRoles();
foreach (string roleName_loopVariable in roleNames)
roleName = r
