问题
I can retrieve the data from excel to GridView.
Below is the code :
If Extension = "xls" Then
connString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & FileUploadPath & sender.text & ";Extended Properties=""Excel 8.0;HDR=Yes;IMEX=2"""
ElseIf Extension = "xlsx" Then
connString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" & FileUploadPath & sender.text & ";Extended Properties=""Excel 12.0;HDR=Yes;IMEX=2"""
End If
Dim query As String = "SELECT * FROM [Sheet1$]"
Dim conn As New OleDbConnection(connString)
If conn.State = ConnectionState.Closed Then
conn.Open()
End If
Dim cmd As New OleDbCommand(query, conn)
Dim da As New OleDbDataAdapter(cmd)
Dim ds As New DataSet
da.Fill(ds)
gvReadFiles.DataSource = ds.Tables(0)
gvReadFiles.DataBind()
da.Dispose()
conn.Close()
conn.Dispose()
But the first row text in excel becomes the header's text in GridView.
That is also not a big problem but the main problem is when any cell is empty in first row in excel I don't get the same header cell empty in GridView. Instead of that I get some text like F2.
Does anyone know the solution?

If the first row of your Excel file contains data and not the header of your columns then your connection string should be changed to
connString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & FileUploadPath & _
sender.text & ";Extended Properties=""Excel 8.0;HDR=NO;IMEX=2"""
Here at http://www.connectionstrings.com/excel#microsoft-jet-ole-db-4-0 in the paragraph related to Excel 2003 you can read
"HDR=Yes;" indicates that the first row contains columnnames, not data. "HDR=No;" indicates the opposite.
