I want to programatically change the position of 'table76' in code behind. It throws an error stating 'The name table76 does not exist in the current context'. Is it because it is inside update progress? My code:

XML

<asp:UpdatePanel ID="UpdatePanel1" runat="server">
   <ContentTemplate>
   <asp:Label ID="Label99" runat="server" Width="145px"></asp:Label>
   </ContentTemplate>
   <Triggers>
   <asp:AsyncPostBackTrigger ControlID="Button4" EventName="Click"/>
   </Triggers>
   </asp:UpdatePanel>

<asp:UpdateProgress ID="UpdateProgress1"  AssociatedUpdatePanelID="UpdatePanel1" runat="server">
<ProgressTemplate>
<table cellspacing="1" class="style56w" runat="server" table id="table76">
<tr>
<td>
<asp:Image ID="Image21" runat="server" DescriptionUrl="~/images/updateprogress.gif"
Height="60px" ImageUrl="~/images/updateprogress.gif" Width="20px" BackColor="White"/>
</td>
</tr>
</table>
</ProgressTemplate>
</asp:UpdateProgress>

code bhind:

table76.Style.Add(HtmlTextWriterStyle.Top, "1140px");

What "code behind"? You cannot show just one line and ask for help. Apparently, table76 is not declared in your context.

'table id=table76' is declared already in the script

Please see my comment to the question. Probably you meant to use ID. Please see: http://msdn.microsoft.com/en-us/library/y81z8326%28v=vs.100%29.aspx[^].

Please try following code where I have modified table in update progress bar

ASP.NET

<asp:updatepanel id="UpdatePanel1" runat="server" xmlns:asp="#unknown">
   <contenttemplate>
   <asp:label id="Label99" runat="server" width="145px"></asp:label>
   </contenttemplate>
   <triggers>
   <asp:asyncpostbacktrigger controlid="Button4" eventname="Click" />
   </triggers>
   </asp:updatepanel>
 
<asp:updateprogress id="UpdateProgress1" associatedupdatepanelid="UpdatePanel1" runat="server" xmlns:asp="#unknown">
<progresstemplate>
<table cellspacing="1" class="style56w"  runat="server" id="table76">
<tr>
<td>
<asp:image id="Image21" runat="server" descriptionurl="~/images/updateprogress.gif" 
Height="60px" ImageUrl="~/images/updateprogress.gif" Width="20px" BackColor="White"/>
</asp:image></td>
</tr>
</table>
</progresstemplate>
</asp:updateprogress>

write using in code behind file

C#

using System.Web.UI.HtmlControls;

after that you can access your table in code behind file

C#

HtmlTable table = UpdateProgress1.Controls[0].FindControl("table76") as HtmlTable;
table.Style.Add(HtmlTextWriterStyle.Top, "1140px");
