cmd.CommandText = "Select * From Acct_Sum"
Dim da As New SqlDataAdapter(cmd)
Dim dt As New DataTable()
da.Fill(dt)
DPList.DataSource = dt
DPList.DataTextField = "Bor_Name"
DPList.DataValueField = "Loan_code"
DPList.DataBind()
DPList.Items.Insert(0, "Select Loan code")

"I want to retrive values in multiple textboxes from columns of sqlDb table on selecteindexchange event of dropdownlist", okay so? What is the actual problem that you are having? So far, you have not asked any kind of a question or described any kind of a real problem.

cn.Open()
cmd.Connection = cn
cmd.CommandText = "Select * from Acct_Sum"
dr = cmd.ExecuteReader
If dr.HasRows Then
dr.Read()
t1.Text = DPList.SelectedItem.Value(dr.Item("Bor_Name"))
t2.Text = DPList.SelectedItem.Value(dr.Item("coBor_Name"))
t3.Text = DPList.SelectedItem.Value(dr.Item("Loan_type"))
t4.Text = DPList.SelectedItem.Value(dr.Item("Loan_Sanc"))
t5.Text = DPList.SelectedItem.Value(dr.Item("Sanc_Perd"))
t6.Text = DPList.SelectedItem.Value(dr.Item("TotalLoan_Disb"))
t7.Text = DPList.SelectedItem.Value(dr.Item("Curt_EMI"))
t8.Text = DPList.SelectedItem.Value(dr.Item("Curt_ROI"))
t9.Text = DPList.SelectedItem.Value(dr.Item("Prinp_Out"))
t10.Text = DPList.SelectedItem.Value(dr.Item("EMI_OVdue"))
End If
cn.Close()

showing error string cannot be converted to integer value
