I have a databound Gridview (with a LINQ datasource). The gridview displays questions from the SQL DB to the user. I've inserted a radio button list into the gridview with 3 horizontal radio buttons with fixed values of 1,2,3 for the user to select. I have a question ID, a tempuserID, and AnswerValue columns set up in the database. It all works nicely.
After the user selects radio buttons, I would like for them to push a button to submit the QuestionID, the associated Radio Button Value (AnswerValue) and their tempUserID into the DB. How do I do this? I'm not sure what to do next and what VB/LINQ code to put in the code behind file in the button click event handler. I'm also not sure on what to use for the tempUserID, can I use the sessionID? I'm using VB and here's my code:
I have three drop down lists that are all databound to a gridview. When the user selects 1. a school, 2. a house number, and 3. a street from seperate drop down lists, bus stops for that address are displayed in a gridview. Everything works fine. After the user selects a valid school/house number/street combination the gridview automatically displays. I would like to add a "Submit" button and not have the gridview display until this button is clicked.

I am trying to edit data using checkbox value. Firstly, I created popup window which using querystring some data from main page. In popup window, I want to change the checkbox value.

It will bring the above value(already displayed thing) { paramspare.Value = "1"; } else { paramspare.Value = "0"; } conn.Open(); cmd.ExecuteNonQuery(); cancelBtn.Value = "Close"; okBtn.Enabled = false; MessagePanel1.Type = MessageType.Information; MessagePanel1.Text = "This computer is spare from now."; } } catch (Exception ex) { MessagePanel1.Type = MessageType.Error; MessagePanel1.Text = MessagePanel1.Text = "This is an error." + ex.Message; } }
