How to update excel through grid
Aug 16 2011 3:55 AM
Hi this is my coding
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
String strConn = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=F:\\Book1.xlsx;Extended Properties=Excel 8.0;";
DataTable ds = new DataTable();
OleDbDataAdapter da = new OleDbDataAdapter("Select * from[Sheet1$]", strConn);
da.Fill(ds);
grvPatient.DataSource = ds;
grvPatient.DataBind();
}
}
string PatientId = "";
protected void btn_save(object sender, EventArgs e)
{
for (int i = 0; i < grvPatient.Rows.Count; i++)
{
bool chk = ((CheckBox)grvPatient.Rows[i].FindControl("myCheckBox")).Checked;
if (chk == true)
{
PatientId = grvPatient.Rows[i].Cells[1].Text;
string Patient = grvPatient.Rows[i].Cells[2].Text;
string Amount = grvPatient.Rows[i].Cells[3].Text;
string Doctor = grvPatient.Rows[i].Cells[4].Text;
string status = grvPatient.Rows[i].Cells[5].Text;
dbquery.InsertChecked(Int32.Parse(PatientId), Patient, Int32.Parse(Amount), Doctor);
dbquery.deleteRecord(Int32.Parse(PatientId));
//update the status to MS Excel
String strConn = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=F:\\Book1.xlsx;Extended Properties=Excel 8.0;";
DataTable ds = new DataTable();
OleDbDataAdapter da = new OleDbDataAdapter("Select * from[Sheet1$]", strConn);
