Question

I have a datagridview which i import an excel file.my excel columns are name,id,sex,grade,seat no .what i want is filter all the columns (multi column filter) in the datagridview except name and id via a textbox. i.e. when i type a single word in the text box i want it to filter the columns of sex,grade and seat no at the same time.
here is the excel importing code to the datagridview....
Private Sub OpenFileDialog1_FileOk(ByVal sender As Object, ByVal e As System.ComponentModel.CancelEventArgs) Handles OpenFileDialog1.FileOk
Dim filePath As String = OpenFileDialog1.FileName
Dim extension As String =
Path.GetExtension(filePath)
Dim header As String = If(rbHeaderYes.Checked, "YES", "NO")
Dim conStr As String, sheetName As String
conStr = String.Empty
Select Case extension
Case ".xls"
'Excel 97-03
conStr = String.Format(Excel03ConString, filePath, header)
Exit Select
Case ".xlsx"
'Excel 07
conStr = String.Format(Excel07ConString, filePath, header)
Exit Select
End Select
'Get the name of the First Sheet.
Using con As New OleDbConnection(conStr)
Using cmd As New OleDbCommand()
cmd.Connection = con
con.Open()
Dim dtExcelSchema As DataTable = con.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, Nothing)
sheetName = dtExcelSchema.Rows(0)("TABLE_NAME").ToString()
con.Close()
End Using
End Using
'Read Data from the First Sheet.
Using con As New OleDbConnection(conStr)
Using cmd As New OleDbCommand()
Using oda As New OleDbDataAdapter()
Dim dt As New DataTable()
cmd.CommandText = (Convert.ToString("SELECT * From [") & sheetName) + "]"
cmd.Connection = con
con.Open()
oda.SelectCommand = cmd
oda.Fill(dt)
con.Close()
'Populate DataGridView.
DataGridView1.DataSource = dt
End Using
End Using
End Using
End Sub

You should bind your DataTable to a BindingSource, which you would add in the designer, and then bind that to the grid. You can then filter the data by setting the Filter property of the BindingSource. It's basically a SQL WHERE clause so, just like in SQL, you can use AND and OR operators to combine multiple criteria, e.g.
myBindingSource.Filter = String.Format("Column1 LIKE '%{0}%' OR Column2 LIKE '%{0}%'", myTextBox.Text)
Just note that you can only use LIKE for text columns, not numbers or dates or anything else.
