Hi
Why dont you use asp.net AjaxFileupload control instead of using asp.net file upload control in update panel.
and file upload is not possible with update panel.
So have a look of the link to upload file using ajax file upload control.
and even if you useAsyncPostBackTrigger for button control on that case post back take place.
Ajax FileUpload Control In Asp.Net or Multiple FileUpload With Progress Example in Asp.Net Using C#.Net

I tried it,
but it still not working:
html code:
<tr> <td>Image :</td> <td style="width: 235px">
 <asp:FileUpload ID="FileUpload1" runat="server" CssClass="form-control" Height="40px" Width="220px" />
<br />
</td>
<td>
<asp:RequiredFieldValidator ID="RequiredFieldValidator25" runat="server" ControlToValidate="FileUpload1" ErrorMessage="Select Image" ForeColor="#FF9900" SetFocusOnError="True" ValidationGroup="one">*</asp:RequiredFieldValidator>
</td>
</tr>
<tr> <td>
<asp:ValidationSummary ID="ValidationSummary1" runat="server" ShowMessageBox="True" ShowSummary="False" ValidationGroup="one" />
</td> <td style="width: 235px">
<asp:Button ID="Button1" runat="server" Text="Add Criminal Detail" ValidationGroup="one" Height="40px" Width="220px" OnClick="Button1_Click" CssClass="btn-warning" />
</td></tr>
</table>
</div>
</center>
<br />
</div>
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="Button1" />
</Triggers>
</asp:UpdatePanel>
</asp:Content>
Backend Code :
if (FileUpload1.HasFile)
{
obj.Image = FileUpload1.PostedFile.FileName;
string path = Server.MapPath(@"Images/"+ FileUpload1.FileName);
FileUpload1.SaveAs(path);}
