Nested repeaters - How to access item on 3rd level without runat server tag?

Hi i have a 3 tiered nested repeater and i need to access the values in the repeater condRptr below on postback, i tried everything but dont seem to be able to get anywhere. I had the table originally within the repeater with runat server in the header template but this threw an error.
Anyone got any ideas??
<asp:Repeater ID="deptRepeater" runat="server" OnItemDataBound="bindDepts">
<HeaderTemplate>
</HeaderTemplate>
<ItemTemplate>
<div id="itemContainer">
<h3 class="fdAccordionHeader"><%# Eval("desc") %><span class="fdAccordionHeaderIcon"></span></h3><asp:HiddenField ID="deptid" runat="server" Value='<%# Eval("dept_id") %>' />
<div class="fdAccordionContent" style="display:none">
<asp:Repeater ID="prodRepeater" runat="server" OnItemCommand="itemToCart">
<HeaderTemplate>
</HeaderTemplate>
<ItemTemplate>
<div>
<h4 class="fdProductHeader"><span class="fdProductHeaderTitle"><%# Eval("desc") %></span><span class="fdProductFeatured"></span><span class="fdProductHeaderPrice">€<%# Eval("price") %></span><span class="fdClearBoth"></span></h4>
<div class="fdProductContent" style="display:none">
<img class="fdProductImage" src="http://wingit.ie/script/app/web/img/frontend/noimg.png" alt="">
<div class="fdProductContentRight">
<div class="fdProductDesc">A helping of our delicious wings, served with fries and a drink of your choice. Perfect if you're particularly hungry!</div>
<input type="hidden" name="product_id" value="2">
<!---->
<asp:LinkButton ID="btnOrder" runat="server" CssClass="fdButton fdButtonOrder" CommandName="addToCart" CommandArgument='<%# Eval("product") %>' ></asp:LinkButton>
<table id="condimentsContainer" cellpadding="0" cellspacing="0" runat="server">
<asp:Repeater ID="condRptr" runat="server">
<ItemTemplate>
<tr><td>
<table id='condiments' cellpadding="0" cellspacing="0" class="fdProductExtraTbl" runat="server">
<tbody>
<tr>
<td><%# Eval("pDesc") %></td>
<td class="fdProductExtraTblPrice"><asp:Label ID="priceLvl" runat="server">€<%# Eval("pPrice") %> x</asp:Label>
<input id="modifier" class="modifier" type="text" name="extra_id[3]" value="0" runat="server"/>
<input id="hdProd" type="hidden" value='<%# Eval("pCode") %>' runat="server"/>
</td>
<td class="fdProductExtraTblIco"></td>
<td class="fdProductExtraTblIco"></td>
</tr>
</tbody>
</table>
</td></tr>
</ItemTemplate>
</asp:Repeater>
</table>
</div>
<span class="fdClearLeft"></span>
</div>
</div>
</ItemTemplate>
<FooterTemplate>
</FooterTemplate>
</asp:Repeater>
</div>
</div>
</ItemTemplate>
<FooterTemplate>
</FooterTemplate>
</asp:Repeater>

Ok so as no-one had any ideas ;) i eventually figured out a nifty work around for this, because i couldn't have the runat server in the header template, i basically put it in the
element like so
<tr ID="dataRow" runat="server"> rest of data </tr>
Then in the C# code on the server side i was able to use the RepeatEreventArgs and cast the as a HtmlTableRow so that i could iterate through the data - simples :)

ASP.NET Repeater Control Checkbox issue

Overview: Clicking on text of first CheckBox in a repeater control clicks the last one. I know why this is happening; association of label tag with element id chkMarkedForDeletion and when that label is clicked it selects the last CheckBox, as all the CheckBoxes have same ID.. damn you repeater control!! I am wondering if there is any way to avoid this? Easy way would be to create individual labels and associate correctly to each CheckBox but that defeats the supposed default behaviour of a CheckBox.
Repeater code:
<asp:Repeater ID="childNodesDataRepeater" runat="server">
<ItemTemplate>
<table style="width: 100%;" cellpadding="0" cellspacing="0" border="0">
<tr>
<td style="width: 200px;">
<asp:CheckBox ID="chkMarkedForDeletion" runat="server" EnableViewState="true" Text="Remove"
Checked='<%# DataBinder.Eval(Container.DataItem, "IsMarkedForDeletion") %>' />
</td>
<td>
</td>
<td style="width: 200px;">
<asp:CheckBox ID="chkHighImpactCause" runat="server" EnableViewState="true" Text="High Impact Cause"
Checked='<%# DataBinder.Eval(Container.DataItem, "IsHighPriority") %>' />
</td>
</tr>
<tr>
<td colspan="3">
<asp:Label ID="header002" runat="server" Text="What caused this problem?" />
</td>
</tr>
<tr>
<td colspan="3">
<asp:TextBox ID="txtProblemCausedBy" runat="server" EnableViewState="true" Width="100%"
Text='<%# DataBinder.Eval(Container.DataItem, "Description") %>' /><br />
</td>
</tr>
<tr>
<td colspan="3" style="height: 5px;">
<hr />
<asp:HiddenField ID="nodeIdentifier" runat="server" EnableViewState="true" Value='<%# DataBinder.Eval(Container.DataItem, "AnalysisID") %>' />
</td>
</tr>
</table>
</ItemTemplate>
</asp:Repeater>
Generated HTML Code for CheckBox:
<INPUT id=chkMarkedForDeletion type=checkbox name=TabContainer$tabProblemResolution$frmProblemResolution1$childNodesDataRepeater$ctl00$chkMarkedForDeletion>
<LABEL for=chkMarkedForDeletion>Remove</LABEL>
...
...
<INPUT id=chkMarkedForDeletion type=checkbox name=TabContainer$tabProblemResolution$frmProblemResolution1$childNodesDataRepeater$ctl02$chkMarkedForDeletion>
<LABEL for=chkMarkedForDeletion>Remove</LABEL>

Thanks,

Make sure the ClientIDMode on the repeater is not set to "Static".
This setting is inheritable from the parent, which goes all the way up to web.config. So if you have to set the ClientIDMode explicitly on the repeater, it means that some parent overrides the default (Predictable) to "Static".

How to put a label over an image

I was trying to look out for a possible solution and am yet to find one. Could you help me out how to add a text over an image.
Below is my code and I want lblWelcome and lblUsername to come over the image.
<img alt="Logo" src="../Resources/Images/Header.gif" style="height: 70px; width: 1000px;"/>
<asp:Label ID="lblWelcome" runat="server" Text="Welcome " CssClass="HeaderMenuText"></asp:Label>
<asp:Label ID="lblUsername" runat="server" CssClass="HeaderMenuText" Text=""></asp:Label>
Would be glad if someone can help me with this.
TIA,
Su

Another way can be by setting your image as the background image of an element and have your text as the child element
e.g.
<div style="background-image: url(../Resources/Images/Header.gif);height:70px;width:1000px;" >
<asp:Label ID="lblWelcome" runat="server" Text="Welcome " CssClass="HeaderMenuText"></asp:Label>
<asp:Label ID="lblUsername" runat="server" CssClass="HeaderMenuText" Text=""></asp:Label>
</div>

Use Css like Given Below:
<style type="text/css">
.lblposition {
position:absolute;
left:789px;
top:30px;
height: 21px;
width: 65px;
}
</style>
Use this css in label like below:
<asp:Label ID ="lbl" runat="server" Text="Search" BackColor="Red" ForeColor="Blue" CssClass ="lblposition"></asp:Label>

<table>
<tr>
<td style="background-image:url("Images/image1.jpg"); height:20px; width:20px;">
<asp:label ID="Lbl1" runat="server" Text="" Fore-color="Red" />
</td>
</tr>
</table>

UpdateProgress and FileUpload problem

I have a fileupload control with an updatePprogress in an updatePanel like this:
UpdatePanel is: updExtraSmall
<Triggers>
<asp:PostBackTrigger ControlID="lnkExtraSmall" />
</Triggers>
<ContentTemplate>
<table>
<tr>
<td style="border: 1px">
<asp:FileUpload ID="fupldExtraSmall" runat="server" />
</td>
<td>
<asp:LinkButton ID="lnkExtraSmall" OnClientClick="javascript:showWait();" OnClick="lnkExtraSmall_click" CausesValidation="false"
runat="server" Text="Upload" />
<asp:Label ID="lblMessage" runat="server" />
</td>
<td>
<asp:Label ID="lblExtraSmallMessage" runat="server" />
</td>
<td>
<asp:UpdateProgress ID="UpdateProgress1" runat="server" AssociatedUpdatePanelID="updExtraSmall">
<ProgressTemplate>
<DIV id="IMGDIV" align="center" valign="middle" runat="server" style="position: absolute;left: 35%;top: 25%;visibility:visible;vertical-align:middle;border-style:inset;border-color:black;background-color:White">
<img src="loading/loading.gif" /><br />
</DIV>
</ProgressTemplate>
</asp:UpdateProgress>
</td>
</tr>
</table>
</ContentTemplate>
and:
function showWait()
{
if ($get('fupldExtraSmall').value.length > 0)
{
$get('UpdateProgress1').style.display = 'block';
}
}
The problem is that the updateProgrss doesn't show.
Can anyone help me please?
Thank you,
Alina

Just Use the asyncfileupload control which come with ajaxcontroltoolkit 3.0 and then upload the file.

Put the UpdateProgress outside the ContentTemplate.

Button not firing onClick below Panel controls in IE

I have a button which is not working when placed below two panels. If I move it above the panels, it works.
It works either way in Firefox. It does not work in IE 8
The button runs this code
protected void Button2_Click(object sender, EventArgs e)
{
panelForm.Enabled = true; //input panel
panelOutput.Visible = false; //output panel
Button1.Visible = true; //input panel button
}
I have some workarounds, but was hoping to find the cause of the issue.
edit: here is the markup of the second panel and button. I've tried moving the button outside of the panel and get the same result.
<asp:Content ID="MainContent" Runat="Server" ContentPlaceHolderID="MainContentPlaceHolder">
<asp:ScriptManager ID="ScriptManager1" runat="server">

<p>

</p>

The problem is that you are using a <form> tag within your content page. The master page already includes a <form> tag and IE appears to be balking at the form within a form. When I removed the <form> tag from your aspx, the button handler ran under IE8.

The sample code is Button2_Click, but your button markup outside of the panels has test_button_Click as the event handler? There are three buttons, so which one are you asking about, I assume the last?

I noticed that you have a tag inside your first panel (panelForm). Also, I don't see a a tag with a runat="server" attribute (although, it could be in a master page). And it doesn't look like your button is inside a form (unless the master page has a form).
The problem is that you can only have one form on a page in Asp.NET WebForms. If you don't have any <form runat="server"> tags on your page, then you buttons will not fire any events on the code-behind.
