I am using this to display a value from database to text box. I am not using the dataset just for this text box but for other dropdown lists too (which are working alright), so the fact that I am using dataset for a textbox is not going to be very expensive in terms of performance.
Basically, I am doing something like this -
public partial class _Default : System.Web.UI.Page
{
private string varState;
protected void get_city(object sender, EventArgs e)
{... //code specific to this function which is working alright
varState = (ds.Tables(0).Rows(0).ItemArray(0)).ToString();
textbox1.text=varState;
}
}
On Build I am getting -
error CS0118: 'System.Data.DataSet.Tables' is a 'property' but is used like a 'method'

I have to create a simple application which scans, displays and stores the info from a barcode. I have been able to sort the scanning and display part of this application but I need to know how to store the infromation entered into a textbox to a database and then be able to display the stored data as a list at a later stage.E.G. Once the "STORE" button is clicked, the information/text within the textbox is stored to a database. Once the "VIEW STORED DATA" button is clicked, the stored information in the database is displayed as a list.I am a complete beginner when it comes to creating web applications using asp.net. Also, the type of database to use (i.e. sql, wamp.etc) and how to link it to my application is also puzzling.
