C#
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
DataTable dt = new DataTable();
dt.Columns.AddRange(new DataColumn[2] { new DataColumn("Id"), new DataColumn("Name") });
dt.Rows.Add(1, "John Hammond");
dt.Rows.Add(2, "Mudassar Khan");
dt.Rows.Add(3, "Suzanne Mathews");
dt.Rows.Add(4, "Robert Schidner");
gvAttendance.DataSource = dt;
gvAttendance.DataBind();
}
}
protected void LoggedIn(object sender, EventArgs e)
{
CheckBox checkedCheckBox = (sender as CheckBox);
if (checkedCheckBox.Checked)
{
GridViewRow checkedRow = (checkedCheckBox.NamingContainer as GridViewRow);
Label lblLoggedInDateTime = checkedRow.FindControl("lblLoggedInDateTime") as Label;
lblLoggedInDateTime.Text = DateTime.Now.ToString();
}
}
protected void btnSave_Click(object sender, EventArgs e)
{
foreach (GridViewRow row in gvAttendance.Rows)
{
string id = row.Cells[0].Text;
string name = row.Cells[1].Text;
string loggedInTime = (row.FindControl("lblLoggedInDateTime") as Label).Text;
InsertData(id, name, loggedInTime);
}
lblMessage.Text = "All Records Saved Successfully!!";
}
public void InsertData(string id, string name, string loggedInTime)
{
//Your saving code.
}
