Hi all check this code....I am getting the following error (at the bottom)
Sub BindGrid()
Dim strConn As String = "Provider=Microsoft.Jet.OLEDB.4.0;" & _
"Data Source= '" & txtDSName1 & "';" & _
"Extended Properties=""Excel 8.0;"""
Dim myData As New OleDbDataAdapter("SELECT * FROM [Sheet1$]", strConn)
myData.TableMappings.Add("Table", "ExcelTest")
myData.Fill(myDataset)
DataGrid1.DataSource = myDataset.Tables(0).DefaultView
DataGrid1.DataBind()
End Sub
Sub MyDataGrid_Update(ByVal sender As Object, ByVal e As DataGridCommandEventArgs)
Dim Cols As String() = {"Year", "Month", "DomListCos", "ForListCos", "TotalListCos",
"DomStocks", "ForStocks", "TotalStocks", "SharesOut", "DomMktCapLocal",

"DomValSharesLocal", "TotalValSharesLocal", "TradValConc", "PriceEarnings",
"PriceBookValue", "DivYield"}
Dim I As Integer
For I = 0 To 20
Dim CurrentTextBox As System.Web.UI.WebControls.TextBox
CurrentTextBox = e.Item.FindControl("edit_" & Cols(I))
Dim ColValue As String = CurrentTextBox.Text
If ColValue <> "" Then
myDataset.Tables("0").Rows(0).Item(I) = CDbl(ColValue)
Else
myDataset.Tables(0).Rows(0).Item(I) = "0.0"
End If
Next
DataGrid1.EditItemIndex = -1
BindGrid()
End Sub
ERROR : Object reference not set to an instance of an object.
