GridView中

<asp:GridView ID="GridView1" Runat="server" DataSourceID="sdsDataSource">
   <Columns>
   <asp:BoundField DataField="Field1" HeaderText="Field1"></asp:BoundField>
   <asp:BoundField DataField="Field2" HeaderText="Field2"></asp:BoundField>
    .....
   <asp:TemplateField>
   <ItemTemplate>
   <asp:Button ID="Button1" Runat=Server OnClick="btnOk_click" />   <%--绑定点击事件--%>
   </ItemTemplate>
   </asp:TemplateField>
   </Columns>
   </asp:GridView>

在vb.net

Sub btnOk_click(ByVal sender As Object, ByVal e As System.EventArgs)
        Dim btnOk As Button = DirectCast(sender, Button)
        btn.Text = "已审批"
        btn.Enabled = "false"

        Dim grdRow As GridViewRow = DirectCast(btnOk.Parent.Parent, GridViewRow)
        Dim strField1 As String = grdRow.Cells(0).Text '获取值
        ..........
        End If

在C#中

void btnOk_Click(object sender , EventArgs e)
   {
   Button btnOk= (Button)sender ;
   GridViewRow grdRow = (GridViewRow)btnOk.Parent.Parent;
   string strField1 = grdRow.Cells[0].Text; //获取gridView值
   string strField2 = grdRow.Cells[0].Text;
   ...
    }
