SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings[“DefaultConnection”].ToString());
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
BindGrid();
}
}
private void BindGrid()
{
btnSubmit.Visible = true;
btnUpdate.Visible = false;
SqlCommand cmd = new SqlCommand(“Select_StudentDetails”, con);
cmd.CommandType = CommandType.StoredProcedure;
SqlDataAdapter ada = new SqlDataAdapter(cmd);
DataSet ds = new DataSet();
ada.Fill(ds);
grvStudentDetails.DataSource = ds.Tables[0];
grvStudentDetails.DataBind();
}
protected void btnSubmit_Click(object sender, EventArgs e)
{
con.Open();
SqlCommand cmd = new SqlCommand(“Ins_StudentDetails”, con);
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.Add(“@StudentName”, SqlDbType.VarChar).Value = txtStudentName.Text;
cmd.Parameters.Add(“@Age”, SqlDbType.Int).Value = txtAge.Text;
int result = cmd.ExecuteNonQuery();
if (result > 0)
{
Response.Write(“Inserted Successfully”);
}
con.Close();
BindGrid();
btnClear_Click(null, null);
}
protected void btnEdit_Click(object sender, EventArgs e)
{
Button btn = (Button)sender;
//Get the row that contains this button
GridViewRow gvr = (GridViewRow)btn.NamingContainer;
hfId.Value = gvr.Cells[0].Text;
txtStudentName.Text = gvr.Cells[1].Text;
txtAge.Text = gvr.Cells[2].Text;
btnSubmit.Visible = false;
btnUpdate.Visible = true;
}
protected void btnUpdate_Click(object sender, EventArgs e)
{
con.Open();
SqlCommand cmd = new SqlCommand(“Update_StudentDetails”, con);
