我的尝试：
代码我为过滤器DataGridView列写的。
Private Sub Connect2Excel（ByVal chemin As String，ByVal lasource As String）
constr =Provider = Microsoft.ACE.OLEDB.12.0;数据源=& chemin& ;扩展属性='Excel 12.0; HDR =是; IMEX = 1;'
con =新OleDbConnection（constr）
sda =新OleDbDataAdapter（选择*来自[& lasource&$]，con）
dt =新数据表
sda.Fill（dt）
DtGrdVwListePAs .DataSource = dt
End Sub
Private Sub CmbBxPorteurSelect_SelectedIndexChanged（sender as Object，e As EventArgs）处理CmbBxPorteurSelect.SelectedIndexChanged
Dim DV As DataView = New DataView（dt）
DV.RowFilter = String.Format（[Porteur] LIKE'％{0}％'，CmbBxPorteurSelect.Items）
如果CmbBxPorteurSelect.SelectedIndex<> -1然后
DtGrdVwListePAs.DataSource = DV
结束如果

I use Visual Studio 2012. I put the contain of an excel file in a DataGridView . I have 2 comboboxes in the form (CmbBxPorteurSelect and CmbBxTypePASelect). I want to filter the DataGridView columns with the item selected in each combobox (the values of the 2 combobox are in different column: column "Porteur" for CmbBxPorteurSelect and column "Statut" for CmbBxTypePASelect). The filtring dos not run correctly. Can some one help? Find down my code in VB.
Thank you for help.

What I have tried:
The code which I wrote for filter DataGridView columns.
Private Sub Connect2Excel(ByVal chemin As String, ByVal lasource As String)
constr = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" & chemin & ";Extended Properties='Excel 12.0;HDR=Yes;IMEX=1;'"
con = New OleDbConnection(constr)
sda = New OleDbDataAdapter("Select * From [" & lasource & "$]", con)
dt = New DataTable
sda.Fill(dt)
DtGrdVwListePAs.DataSource = dt
End Sub
Private Sub CmbBxPorteurSelect_SelectedIndexChanged(sender As Object, e As EventArgs) Handles CmbBxPorteurSelect.SelectedIndexChanged
Dim DV As DataView = New DataView(dt)
DV.RowFilter = String.Format("[Porteur] LIKE '%{0}%'", CmbBxPorteurSelect.Items)
If CmbBxPorteurSelect.SelectedIndex <> -1 Then
DtGrdVwListePAs.DataSource = DV
End If
End Sub
Private Sub CmbBxTypePASelect_SelectedIndexChanged(sender As Object, e As EventArgs) Handles CmbBxTypePASelect.SelectedIndexChanged
Dim DV As DataView = New DataView(dt)
DV.RowFilter = String.Format("[Statut] LIKE '%{0}%'", CmbBxTypePASelect.Items)
If CmbBxPorteurSelect.SelectedIndex <> -1 Then
DtGrdVwListePAs.DataSource = DV
End If
End Sub
