I have problem when saving data from gridview into SQL database.
When i save the data, only certain data was saved. I want to save all the data. Data that was not saved is from the column where i display a drop down list while editing from the gridview.

Another problem is when there is no data in certain column in the grid view and when i click the SAVE button, " " is saved into the database. How to make sure that " " is not saved into the table when there is no data in the gridview?

Here is my coding to save data from grid view when user make selection and click SAVE button (Please help me to solve my problem):

                    SqlCommand cmd = new SqlCommand(insertString, SQLConn);

                        Response.Write("<script>alert('Data saved...')</script>");

I guess you need to do something like
DropDownList ddlTest = (DropDownList)GridView1.Rows[GridView1.SelectedIndex].FindContro("your Dropdown id")

then use ddlTest.Text or other property and assign it.
I hope it may solve your problem.
