.net 我想筛选我的datagrid视图

我想根据两个文本框（名字（

fname

）和第二个名字（

sname

）过滤我的DataGridView，但它只根据

fname

过滤

这是我的密码：

Try

Dim conn As New OleDbConnection
    conn.ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + IO.Directory.GetCurrentDirectory + "\Kyc.mdb"

    Dim cmdfilter As String = " select ID as الرقم_الوطني,fname as الاسم_الاول,sname as الاسم_الثاني,thname as الاسم_الثالث,finame as الاسم_الرابع from O_name where fname like '%" & fname.Text & "' OR sname like '%" & sname.Text & " ' "
    Dim cmdcommand As New OleDbCommand
    Dim dataadabtar As New OleDbDataAdapter
    Dim table As New DataTable

    With cmdcommand
        .CommandText = cmdfilter
        .Connection = conn
    End With

    With dataadabtar
        .SelectCommand = cmdcommand
        .Fill(table)
    End With


    DataGridView1.DataSource = table
    DataGridView1.DataSource = Nothing
    For i = 0 To table.Rows.Count - 1
        With DataGridView1
            .Rows.Add(table.Rows(i)("الرقم_الوطني"), table.Rows(i)("الاسم_الاول"), table.Rows(i)("الاسم_الثاني"), table.Rows(i)("الاسم_الثالث"), table.Rows(i)("الاسم_الرابع"))
        End With
    Next

Catch ex As Exception
    MsgBox(ex.Message.ToString)

End Try
End Sub

---

第一个首选项给定fname和第二个首选项给定sname

当我尝试此代码时，没有任何结果，我有两行具有相同的fname但不同的sname。当我尝试此操作时，结果中会显示两行，但当我键入sname时，我只需要一行

Dim cmdfilter As String = " select ID as الرقم_الوطني,fname as الاسم_الاول,sname as الاسم_الثاني,thname as الاسم_الثالث,finame as الاسم_الرابع from O_name where fname like '%" & fname.Text & "' OR sname like '%" & sname.Text & " ' Order by fname,Sname"
