Move variables from one form to another form

Quote:

There are many way to pass the value from one page to another.
You can pass value through Querystring or you can use Session for the same.
You only need to Manage as your logical need and after use Dispose all as Security Purpose.

<input type="hidden" id="hiddenPersonalDetails" runat="server" />
<input type="hidden" id="hiddenEducationalDetails" runat="server" />
<asp:textbox id="txtName" runat="server" xmlns:asp="#unknown"></asp:textbox>
<asp:textbox id="txtEducation" runat="server" xmlns:asp="#unknown"></asp:textbox>

protected void btnSubmit_Click(object sender, EventArgs e)
{
hiddenPersonalDetails.Value=txtName.Text;
hiddenEducationalDetails.Value=txtEducation.Text;
}

string personalDetails=hiddenPersonalDetails.Value;
string educationalDetails=hiddenEducationalDetails.Value;

string connectionString = "Your connection string";
using (SqlConnection connection = new SqlConnection(connectionString))
using (SqlCommand command = connection.CreateCommand())
{
command.CommandText = "INSERT INTO dbo.table(PersonalDetails, EducationalDetails) VALUES (@personalDetails, @educationalDetails)";

command.Parameters.AddWithValue("@personalDetails", personalDetails);
command.Parameters.AddWithValue("@educationalDetails",educationalDetails);
            
connection.Open();
command.ExecuteNonQuery();
connection.Close();
}
