I have a page that holds two iframes sitting next to each other inside of two divs. There is a scrollbar on the second iframe that I want to remove so that the iframe scrolls with the browser scrollbar. The iframe with the unwanted scrollbar contains a gridview and when the data becomes longer than the browser height, the scrollbar appears.
<div data-dx-role="view" data-dx-name="Index" data-dx-title="Home" style="height: 100%">
<div data-dx-target-placeholder="content">
<div id="treeframe" class="ui-widget-content" style="position: absolute; overflow-x: scroll; width: 20%; overflow: hidden; bottom: 0px; top: 0px; left: 0px; z-index: 1">
<iframe class="iframeformat" height="1100" style="width: 100%; overflow: auto;" id="ifrmtree" src="./SiteTree.aspx"></iframe>
</div>
<div id="contentframe" class="mobform" style="position: relative; overflow: hidden; top: 0px; width: 100%%; height:100%" aria-haspopup="False">
<iframe id="ifrmlogin" class="embed-responsive-item" src="./DashboardHome.aspx" style="height: 1100px; overflow: hidden; width: 100%; border: none;"></iframe>
</div>

This Javascript solution was helpful to me a couple of years ago, but it will only work is the iframe contents resides on the same domain:
<script>
function resizeIframe(obj) {
obj.style.height = obj.contentWindow.document.body.scrollHeight + 'px';
}
</script>
<iframe src="..." frameborder="0" scrolling="no" onload="resizeIframe(this)" />

my aspx codes
<div style=" overflow-y:auto; height:368px; margin-top: -50px; border-top-style: groove; border-right-style: groove; border-left-style: groove; width: 602px; margin-left: 0px;" >
<asp:Repeater runat="server" ID="Repeater1" >
<ItemTemplate>
<div style="border-top: thin none #BBCEB3; border-bottom: thin none #BBCEB3; padding: 10px; width: 548px; margin-top: -10px; right: 10px; left: 10px; border-left-width: thin; margin-left: 15px; background-color: #fffff0; border-left-color: #BBCEB3; border-right-color: #BBCEB3; border-top-style: groove; border-bottom-style: groove;">
<br />
<div style="width: 58px; height: 40px">
<asp:Image ID="Image2" runat="server" Height="59px" ImageAlign="Top" ImageUrl='<%#Eval("SProfilePic") %> ' Width="55px" />
</div>
<div style="width: 307px; margin-left: 65px; margin-top: -60px">
<asp:Label ID="Label6" runat="server" Font-Bold="True" Font-Names="Arial" ForeColor="#000066"><%#Eval("SenderName") %> </asp:Label>
</div>
<div id="status" style=" width: 461px; margin-left: 78px; margin-top: 11px;"> <asp:Label ID="Label7" runat="server" Font-Italic="False" ForeColor="Black" Font-Size="Medium"><%#Eval("Messages") %> </asp:Label>
</div>
<div style="margin-left: 400px; background-color: #C0C0C0;">
<asp:Label ID="Label11" runat="server" Text="" Font-Size="Small"><%#Eval("Time") %> </asp:Label>
</div>
</div>
</ItemTemplate>

Put server controller there for example this:
<asp:Button ID="BtnOutside" runat="server" Text="Random" style="margin-left:-999px;" />
And then use
Page.SetFocus(Me.BtnOutside.ClientID);
To get focus to that button which is not visible to the client because of the negative margin. This should push the scroll bar to the bottom.

Put this in your code wherever you want to Focus on -- You can use this
multilple times in the same code set just change the "ID"
<asp:Button ID="FocusBottom" runat="server" Text="Random" style="margin-left:-999px;"
In the event(button click whatever) put in this.
Page.SetFocus(FocusBottom);
Change the (#######) to "ID" you want to call

System.OutOfMemoryException with asp:FileUpload

I have an ASP.NET page that has a FileUpload control inside.
When I try to upload a third file I am getting:
System.OutOfMemoryException
at System.Convert.FromBase64String(String s)
at System.Web.UI.ObjectStateFormatter.Deserialize(String inputString)
at System.Web.UI.ObjectStateFormatter.System.Web.UI.IStateFormatter.Deserialize(String serializedState)
at System.Web.UI.Util.DeserializeWithAssert(IStateFormatter formatter, String serializedState)
at System.Web.UI.HiddenFieldPageStatePersister.Load()
here's my code:
<td style="width: 60%; height: 67px; vertical-align: top">
<div class="fileinputs" id="div2" style="left: 0px; top: 0px; width: 100%; vertical-align: middle">
<div id="div3" class="fakefile" style="left: 0px; top: 0px; vertical-align: middle">
<asp:TextBox ID="txtFileUpload" runat="server" Width="265px" CssClass="borde-form"
Height="15px" ValidationGroup="docs" />
<img name="imgExaminar" alt="Examinar" src="../../Images/botExaminar.gif" style="cursor: hand;
width: 81px; height: 20px; vertical-align: middle" />
</div>
<asp:FileUpload EnableViewState="true" ID="fileUpload" runat="server" Width="368px"
Height="19px" CssClass="hidden" />
</div>
<asp:CustomValidator ID="cvattachment" runat="server" OnServerValidate="cvattachment_ServerValidate"
ControlToValidate="fileUpload" ErrorMessage="Existe un archivo con el mismo nombre"
Font-Bold="False" Font-Names="Arial" Font-Size="X-Small" ValidationGroup="docs"></asp:CustomValidator>
</td>
<td style="width: 30%; height: 67px; vertical-align: top">
<asp:ImageButton ID="imgAdjuntar" runat="server" ImageUrl="~/Images/botAdjuntar.GIF"
OnClick="imgAdjuntar_Click" ValidationGroup="docs" Height="20px" Width="66px"></asp:ImageButton>
</td>
When I click on my imgAdjuntar, I am getting the error, but the imgAdjuntar_Click method is never called, but the Application_Error on the Global.asax is fired instead.
Plus, none of my breakpoints are being stepped into, the error occurs before reaching the application code.
Maybe the control is the one that's failing?
What can I do?
Thank you!

Make sure that you are not storing files within the ViewState.
In addition, try to disable the ViewState for the entire page.

Image not displayed in chrome and firefox using "progid:DXImageTransform.Microsoft.AlphaImageLoader"

i am using "progid:DXImageTransform.Microsoft.AlphaImageLoader" to display iamge in div
My code is:
<body class="style_page" style="margin: 0px; background: white;" onload="onLoad()"
onunload="onUnload()" onresize="onResize()">
<div id="mediaPlayer" style="position: absolute; visibility: hidden;">

font-size: 10pt; background: white;">
<div class="placeholder" style="left: 0%; top: 0%; width: 100%; height: 166%;">
<div class="outline" style="filter: progid:DXImageTransform.Microsoft.AlphaImageLoader(enabled=true, sizingMethod=scale, src='output6.jpg');">
</div>
</div>
</div>
It works fine in IE8 but doesn't work in Mozilla and google chrome
Plz help
Thanks

Mozilla, Opera, G.Chrome and other browsers doesn't support Microsoft filters for transform text and images(controls). I think that every brower producer use diferent method.
Try to find help on their sites, and you must write javascript functions to recognize browser whos load page you developed.

ASP.NET Display "Loading..." message while update panel is updating

Hello I am creating an ASP.NET/C# application
I have an update panel that takes time to update.
Is there a way to display a "Loading... Please Wait" Message during the time of the calculations?
Currently I am using AJAX panel animation fade in/fade out, to make the panel disappear while calculating and then reappear when done. But that is not very practical.
I need to display a message if possible.
Thank you for any help.
this is the code of my panel:
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<Triggers>
<asp:AsyncPostBackTrigger ControlID="Button1" EventName="Click"/>
</Triggers>
<ContentTemplate>
//Contents goes here
</ContentTemplate>
</asp:UpdatePanel>
And the Ajax Panel animation extender
<ajaxToolkit:UpdatePanelAnimationExtender ID="UpdatePanelAnimationExtender1" runat="server" TargetControlID="UpdatePanel1">
<Animations>
<OnUpdating>
<FadeOut Duration="1" Fps="20" />
</OnUpdating>
<OnUpdated>
<FadeIn Duration="2" Fps="20" />
</OnUpdated>
</Animations>
</ajaxToolkit:UpdatePanelAnimationExtender>

You can use code as below when
using Image as Loading
<asp:UpdateProgress id="updateProgress" runat="server">
<ProgressTemplate>
<div style="position: fixed; text-align: center; height: 100%; width: 100%; top: 0; right: 0; left: 0; z-index: 9999999; background-color: #000000; opacity: 0.7;">
<asp:Image ID="imgUpdateProgress" runat="server" ImageUrl="~/images/ajax-loader.gif" AlternateText="Loading ..." ToolTip="Loading ..." style="padding: 10px;position:fixed;top:45%;left:50%;" />
</div>
</ProgressTemplate>
</asp:UpdateProgress>
using Text as Loading
<asp:UpdateProgress id="updateProgress" runat="server">
<ProgressTemplate>
<div style="position: fixed; text-align: center; height: 100%; width: 100%; top: 0; right: 0; left: 0; z-index: 9999999; background-color: #000000; opacity: 0.7;">
<span style="border-width: 0px; position: fixed; padding: 50px; background-color: #FFFFFF; font-size: 36px; left: 40%; top: 40%;">Loading ...</span>
</div>
</ProgressTemplate>
</asp:UpdateProgress>
