    I am using Rad Controls version: Telerik.Web.UI 2008.01.0619.35.
    I have nested splitters and Rad panes, in which I am trying to align Image vertical middle and horizontal center.  I am using asp:Panel inside RadPane, and setting the HorizontalAlign property of panel to align center.  Horizontal Align is working fine in IE but not on firefox.  I have to use Div tag as Image container because I want to resize the image.

    Also I need to vertical-align: middle for the content in RadPane. Below is the code:

    <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="TestResize.aspx.cs" Inherits="VX2Casting.TestResize" %>
    <%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>
    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "">
    <html xmlns="">
    <head id="Head1" runat="server">
        <style type="text/css">
        html, body, form
            height: 100%;
            margin: 0px;
            padding: 0px;
            overflow: hidden;
    <telerik:RadCodeBlock ID="radCodeBlockMain" runat="server">
        <script type="text/javascript">
            function OnLvLargeViewResizeHandler() {
                var imgLvLargeView = document.getElementById("imgLvLargeView");

                //Resize Image large view
                var nWidthL, nHeightL, nImgWidthL, nImgHeightL, nOrgWidthL, nOrgHeightL;
                var RadSplitterLvRight = $find("<%=RadSplitterLvRight.ClientID%>");

                if (RadSplitterLvRight != null) { var RadPaneLvRightTop = RadSplitterLvRight.getPaneById("RadPaneLvRightTop"); nWidthL = RadPaneLvRightTop.get_width() - 10; nHeightL = RadPaneLvRightTop.get_height() - 10; }
                var imgLvLargeViewTmp = new Image(); imgLvLargeViewTmp.src = imgLvLargeView.src; nOrgWidthL = imgLvLargeViewTmp.width; nOrgHeightL = imgLvLargeViewTmp.height;

                if (nWidthL > 0 && nHeightL > 0) {
                    var p = 0; var pH = nOrgHeightL / nHeightL; var pW = nOrgWidthL / nWidthL;
                    if (pH > pW) { p = pH; } else { p = pW; }
                    nImgWidthL = nOrgWidthL / p; nImgHeightL = nOrgHeightL / p;

                if (imgLvLargeView != null) {
                    var divImageObj = imgLvLargeView.parentNode;
                    if (nImgWidthL > 0 && nImgHeightL > 0) {
                        if (divImageObj != null) { = (nOrgWidthL > nImgWidthL ? nImgWidthL : nOrgWidthL) + 'px'; = (nOrgHeightL > nImgHeightL ? nImgHeightL : nOrgHeightL) + 'px'; }
                    if (divImageObj != null) { = "visible"; }

                                                LV Navigation
                <telerik:RadSplitter ID="RadSplitter1" Runat="server">

    Could you please suggest me how to align content in Radpane Horizontal center and Vertical middle on Internet explorer and Firefox browsers.

    Hello Babak ,

    Your question is not directly related to the RadControls and radSplitter but to general ASP.NET and CSS knowledge. If you succeed to center the image in a standard DIV element, all you should do after that is to put this DIV element in the RadPane and everything should work as expected. You can find different tips and techniques of centering elements in their wrappers on the web, e.g in the article below:
