Forms Data Controls :: Nested Repeater Control Does Not Work?
Sep 8, 2010
I have a presentation to the CFO in two hours. I can't get a nested repeater control to work right, something to do with teh placement of the <table> tags I think.The first repeater first section works fine, then the child repeater shows the first child section right, but the next section of the parent repeater loses all the formatting applied at the parent table. I've tried vaious permutations of where to place the closing table tag of the outer and the inner and get different results, but never the right results.
Here is my current code:
<tr
style="font-size:small">
<th
style="width:100px">[code]....
These are the results I get:

What I'm trying to do is find a control within a nested repeater when the OnItemDataBound event is fired on the 'main' repeater.
[Code]....
This has driven me mental! And I've done stacks of web searches and ended up confusing myself even further.

what changed do I need to make to my code for it to achieve what I'm after.
At the moment I am getting a "cannot cast to type" error message with the below code.
I have also tried calling the ItemDataBound method in with the parent repeater tags and had no errors but when I clicked on the button it would just move back to the top of the page and would not hide or show any data. Also I have made the div style to none but the first record still shows its child but the rest don't.

when i am trying to use a repeater to display data in a wizard control, everything seems worked as expected before i change the value of wizard's DisplaySideBar, here is my demo code:Test.aspx:
[Code]....
Test.aspx.cs:
[Code]....
guys who intrest on this you can copy this code and test it on your pc, when we click the link button in repeater's item will do nothing at the first time but it will work when we click it again.i have debug this and found that when the page is not in post back, the linkbutton's id will be "MainWizard_rpMain_ctl01 _lbEdit" in prerender method but after render it will change to "MainWizard_rpMain_ctl04 _lbEdit", but when page have been post back, the clientid will be correct as "MainWizard_rpMain_ctl01_lbEdit" and then event can be fired correctly.i thought this is a bug of .net framework, when i set the value of wizard's DisplaySideBar, it will ask to re-create controls but repeater haven't clean the item's count and then recreate item will use wrong item index, i hope this message can be post to .net framework team and they can find out what's the matter on it.

Edit: I have a working solution already - I would just like to know why my original attempt didn't work. My original attempt is the code below.
I'm using the approach I found here:[URL] 306154 to implement a nested Repeater. Each parent item has one or more children items (the point of having the nested Repeater) with a dropdown horizontally aligned to each child item. In an effort to re-use the nested part of the Repeater I wanted to develop that piece as a user control but couldn't get it to work. I am wondering if it is even possible and if so how?
Here is my user control apsx:
<asp:Repeater ID="NestedRepeater" runat="server">
....
<ItemTemplate>
<tr class="text" id="RepeaterItemRow" runat="server">
<td>
<%#DataBinder.Eval(Container.DataItem, "Name") %>
</td>
<td>
</td>
<td>
</td>
<td>
</td>
<td>
</td>
<td>
</td>
</tr>
</ItemTemplate>
And here is my code behind for the user control. I noticed when I debugged NestedDataSource was null even though in the parent page load the data is there:
public DataSet NestedDataSource
{
get;
set;
}
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
NestedRepeater.DataSource = NestedDataSource;
NestedRepeater.DataBind();
}
}
In the parent Repeater in the `<ItemTemplate> I have:
<asp:RepUC ID="NestRep" runat="server" NestedDataSource='<%#((DataRowView)Container.DataItem).Row.GetChildRows("nestedrel") %>'>
And finally the page code behind:
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
BuildWBS();
}
}
private void BuildPage()
{
DataSet ds = new DataSet();
ds = DataAccessLayer.GetData("System");
ds.Relations.Add("nestedrel", ds.Tables[0].Columns["Id"], ds.Tables[1].Columns["ParentId"]);
ParentRepeater.DataSource = ds;
ParentRepeater.DataBind();
}
The page loads but nothing relating to the repeater appears on the screen. So, can you see anything wrong with what I have? Is the way I tried doing this even possible?

Users can reply to a comment made in the parent repeater by clicking a link that opens a popup that inserts a row in the replies table. This is then displayed in the repeater as soon as the lists refresh. What I need to do is have a Delete comment link that only the user that inserted the reply can utilize. How do you get the command or onclick from a ImageBUtton that is in the child segment?

The Enabled='<%# isEnabled() %>' disables the button foe users that are not logged in...that seems to work OK

nested repeater like this:
<asp:Repeater ID="repeaterReportListByJob" runat="server" DataSource='<%# GetReportsByJobNID(Eval(Container.DataItem, "JobNID")) %>'>
It seems my Eval(Container.DataItem, "JobNID") is not working and I assume this is because the datasource of the outer (parent) repeater is an anonymous type. So how am I supposed to access a particular field of my anonymous type?

I have a nested repeater which displays a food menu - e.g.
Sub Heading
- Food 1
- Food 2
- Button 1
Another Heading
- Food 1
- Food 2
- Button 2
etc. etc.
What I have is a series of buttons inside the itemtemplate of the parent repeater (button 1 and button 2) which, when clicked, i need to somehow add a new blank textbox to below food 2 in whichever section it is clicked
I am having trouble doing this. See my code snippet below:
[Code]....
When I run this though, I receive an error of "object reference not set to an instance of object..."
Do I need to actually find a control within the footertemplate itself?

I'm having a problem trying to retrieve a dropdownlist value that is located within a nested repeater. Basically I'm trying to create a shopping cart that allows the user to select a shipping method and the shipping method is contained in the repeater. So my page structure looks something like this.
Gridview
[Code]....
To me this should work, but the problem I'm facing is that there are no repeater items. The Items.Count property in the repeater is 0. I am not calling DataBind on the Gridview nor the Repeater before this code is reached (this code is the first thing that happens in my button click event) and my binding is done inside a !IsPostBack statement in my page load. I've made sure databinding is not occurring by setting breakpoints on the code that databinds both the gridview and repeater.
It seems to me like the nested repeater is losing it's viewstate or something on a postback. If that's the case, how can I get the selected value of that dropdown control inside a nested repeater?

I have two repeaters (one nested in the other) with checkboxes for each. AutoPostback is set to true. ViewState is enabled. for the repeaters. The layout is similar to a treeview control.
I am having trouble retaining state for the child repeater's checkboxes when I check the parent repeater's checkboxes. How can I retain these child checkboxes as I click on the parent's.

Nested Repeater Issue: Each category list gets populated with the same set of date values rather then being populated with the data associated with that category. Trying to Do: Trying to group FAQ's by category and then list them using the repeaters.
The data is queryed though a business logic layer object that makes a call to the data access layer object. The data access layer object uses linq to sql to return data. There are 3 parameters that are passed into the innerDataSource's ObjectDataSource control to populate the nested repeater control (propID, CatID, isVisible).
With the debugger, the correct data is being returned and written to the nested repeater firing from the nested repeater's ItemDataBound event. Once this event is finished, another event fires and runs the FAQRule object again on the business logic layer which re-populates the nested repeater with the same data for each category. I have 2 repeaters, outerRepater (parent) and innerRepeater(child) with 2 ObjectDataSource controls innerDataSource and outerDataSource. See code below : ASP Page:
<asp:Repeater DataSourceID="outterDataSource" EnableViewState="false" runat="server">
<ItemTemplate>
<%# Eval("Description") + " " + this.Property.PropertyName %>
<asp:Repeater EnableViewState="false" runat="server" DataSourceID="innerDataSource">
<HeaderTemplate>
<ul style="width: 500px">
</HeaderTemplate>
<ItemTemplate>
<div><%# Eval("Question") %></div>
<div><p><%# Eval("Answer") %></p></div>
</ItemTemplate>
<FooterTemplate>
</ul>
</FooterTemplate>
</asp:Repeater>
<asp:ObjectDataSource ID="innerDataSource"
runat="server"
SelectMethod="FetchFAQSByPrpAndCatID"
TypeName="PropertySite.BusinessRules.FAQRules">

I am using a repeater to build a custom table. However, I can't figure out how to make the table show subtotal if the next rows tour does not match the previous rows.
Something similar to that.
row1 tour1
row2 tour 1
tour1 subtotal
row3 tour2
row4 tour2
subtotal
total
[code].....
but this shows all the data in the nested repeater not the ones that match the parentrepeater fields for example tour,theme,dep7 should match in the child repeater

I have a repeater, and within it I have a button that shows up for each data entry. I would like it so that when I click the button, a certain action takes place, however this does not work. When I click the button nothing happens at all (the page just refreshes), however as soon as I move the button outside of the repeater, it then works.I used to get this error when when I pressed the button:
Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration"
But I then disabled event validation...when I disabled it I didn't get the error anymore, but the button remained useless.

I have the following code in an aspx form for an asp:Repeater
<ItemTemplate>
<tr class='<%#Container.ItemIndex % 2 == 0 ? "normalRow" : "alternateRow" %>' >
<tr>
<td>
<asp:LinkButton ID="LinkButton1" runat="server">blabla
<%#DataBinder.Eval(Container.DataItem, "ListName")%>
</asp:LinkButton>
</td>
</tr>
</ItemTemplate>
Which produces a syntax error (and a sqiggle blue underline) on
<%#Databinder.Eval(Container.DataItem, "ListName")%>
the build tells me I have an invalid character in the position before the opening <%
above
This only happens after I add the conditional class for the <tr> tag
"<tr class='<%#Container.ItemIndex..."
before I add the above line (to replace the <AlternatingItemTemplate>) everythings ok.
