Hello everyone, Here is simple code how to resize BitmapViewer web control on client side: Code:<%@ Page Language="vb" AutoEventWireup="false"%>
<%@ Register TagPrefix="aur" Namespace="Aurigma.GraphicsMill.WebControls" Assembly="Aurigma.GraphicsMill.WebControls" %>
<script runat="server">
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
If Not Page.IsPostBack Then
BitmapViewer1.Bitmap.Load(Server.MapPath("TestImages/building.jpg"))
Else
'Check whether control width and height were changed on client side
If Request.Form("newWidth")<>"" And Request.Form("newHeight")<>"" Then
BitmapViewer1.Width=Unit.op_Implicit(Int32.Parse(Request.Form("newWidth")))
BitmapViewer1.Height=Unit.op_Implicit(Int32.Parse(Request.Form("newHeight")))
End If
End If
End Sub
