Hi sriya,
i beleive that you need to create a DataRow to add a new ROW as shown below
VB Code:
Dim dtcmp As DataRow = m_dt_test.NewRow
dtcmp("CompanyName") = txtCompany.Text
'etc
'etc
m_dt_test.Rows.Add(dtcmp)
m_DataAdapter.Update(m_dt_test)
second this line "in ur code" has an error, there is . before m_dt_test
"m_dataAdapter_test.Update(.m_dt_test)" it shows the following error.
hope this helps...
Regards,
