View 2 RepliesQuery 1 - Grid View: - I have an excel sheet which I import into gridview at runtime. For excel sheet import, I have a fileupload dialog box and an asp.net button control which when clicked imports the sheet contents into a gridview. The problem is I have my fileupload box and button control in a page called Default.aspx and I need the gridview get displayed maximized in a new page called Default2.aspx.
Also, I need to specify the row number of the field titles from the excel sheet dynamically at runtime so that the gridview appends any new field/column from that row on. The excel sheets I use contain complex formatting. Is there anyway to display the excelsheet contents as they have been defined and formatted?
Query 2 - Sessions: - I add nodes to my treeview dynamically at runtime. Since HTTP is a stateless protocol, the changes which I do remain only for that session. How do I append the changes I do to the treeview simultaneously in the code?
- I have appended 2 extra columns into the excel sheet generated gridview which take input through dropdownlistbox control at runtime. How do I update and retain those changes in the gridview?

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.

How to validate user entry to cell in GridView and replace the cell value on the other column?
Ex :
i have a gridview with 2 columns (A & B), on both columns i change it to TemplateField (TextBox).
Now on whatever row on column A, i want to validate the user entry when user leave the cell, how to achieve that ?
Based on user entry on column A, i will do some data lookup and get a value returned from the server, how to tell the gridview to replace the value on column B (on the same row) based on the value returned from the server.
I have Gridview that is populated from a data table, there are two additional template columns which are not bound (one checkbox and one textbox). I intend for the users to fill data in the unbound textbox and check the checkbox as needed. (there really is a good reason why the data is constructed in this way)
here is the problem, when the user enteres data into the textbox and hits enter, the gridview appears to postback, which wipes out the checkbox and the data in the textbox.
I tried setting the enable view state of the grid to false, that was supposed to stop postback but no luck. I have the enable view state of the textbox and checkbox set to true and autopostback set to false. but still no luck
so I need to either stop the postback or intercept the enter key in the text box and cancel the action, but that is a bit beyond me at this point
I am familiar with populating a gridview with data. I am able to bind the Data pulled from the database into the gridview

gridview.DataSource = null;
gridview.Databound.
