I'm creating a navigation menu. I've to render repeater control ul-li tags and menuitems can range upto N levels. I need to add a child repeater control dymnamically to parent control?
EDIT:
Example -
ul-li can goto n levels
<ul>
<li>
<ul>
<li>
<ul>
<li></li>
<li></li>

I found the article about Nested GridView Example in ASP.Net using C# and VB.Net
I tried it with a third level, but have problems of binding data. How it could work?
<asp:GridView ID="gvCustomers" runat="server" AutoGenerateColumns="false" CssClass="Grid"
DataKeyNames="t1000_customer_id" OnRowDataBound="OnRowDataBound">
<Columns>
<asp:TemplateField>
<ItemTemplate>
<img alt="" style="cursor: pointer" src="./images/plus.png" />
<asp:Panel ID="pnlOrders" runat="server" Style="display: none">
[CODE]...
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.

I am using a repeater control and i want to use one more repeater control inside the existing repeater control .
Like this:
<asp:Repeater ID="Repeater1" runat="server"> <HeaderTemplate> </HeaderTemplate>
<ItemTemplate>
<!-- start child repeater --> Here I want to use one repater control <!-- end child repeater -->
</ItemTemplate>
</asp:Repeater>
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
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?
I'm currently working with a repeater which has some number of drop down lists in it determined by how many items are databound to it. I wanted to add an event to each of these drop down lists in the scenario that a user changes the selected index.
Here is what I have for the repeater (Note that I am doing all of the databinding in the codebhind.):
[Code]....
I am setting the OnTextChanged event here, however I did some experimenting with using the different events. I found that my method will not run when I am using the OnTextChanged or OnSelectedIndexChanged events. However, if I use some other events like OnLoad or OnPreRender, the method I have it set to actually runs. So in short, why is it that when I put this drop down list in the repeater only SOME of the events seem to work?
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?
[Code]....
The Enabled='<%# isEnabled() %>' disables the button foe users that are not logged in...that seems to work OK
i'm new on this forum and my english is not the best, so i hope that i can explain my problemI have a gridview nested in a Repeater, this is the markup :
<ItemTemplate>
<asp:GridView ID="GridView1" EmptyDataText="<%#((mioDataTable)Container.DataItem).categoria %>" runat="server" AutoGenerateColumns="False" CellPadding="4" CssClass="grid" DataKeyNames="id"
[code]...
What I'm trying to do is find a control within a nested repeater when the OnItemDataBound event is fired on the 'main' repeater.

This has driven me mental! And I've done stacks of web searches and ended up confusing myself even further.
I am using ASP .NET 2.0 C#.
I have a Repeater that I created in my code behind. I want to create a nested repeater inside of that parent repeater. How do I go about doing that?
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:
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 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?
am using C# .net.. in my page am having nested repeater control.. in child repeater there is check box and a hidden ID. i want to store(here am get strucked) the ID of checked box in to my data base.. look at the below code..

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 am using nested repeaters and wanted to access a value from my parent repeater within the child...is this possible?
View 3 RepliesI am trying to find a way in whihc I CAN Move the columns of nested repeaters from one to another. Like I have three caegories of products say A,B,C and I will have X,Y,Z products within each categories and I am trying to find a way of I can find a way that on client side the user can drag items from one category to another like the drag functionality of Ajax control kit ReOrder List.

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">

Can anybody tell me how I can add ItemTemplate to a Template column in a GridView. What I am doing right now is that I am adding Columns to GridView from code. And now I need to add a Template column with a ItemTemplate.
And my ItemTemplate should contain a label.
I have to add row in gridview dynamically when a button is clicked on my page
Each Row which have to be added contains a dropdownlist(ddlQues) in which questions are binded
On selecting question from ddlQuestion I have to bind another dropdownlist(ddlAnswers)with respective
answers in that row of gridview
So autopostback property of ddlQuestion is set to be true
Everytime when button is clicked a new row is inserted in gridview and same process repeats............
I had tried following javascript:
<script type="text/javascript">
function AddNewRecord()
{
var grd = document.getElementById('<%= gvResponse.ClientID %>');
alert(grd);
var tbod=grd.rows[0].parentNode;
var newRow=grd.rows[grd.rows.length - 1].cloneNode(true);
tbod.appendChild(newRow);
return false;
}
</script>
and calling this function on button
<asp:Button ID="btnResponse" runat="server" Text=" New Response" CssClass="button3" OnClientClick="return AddNewRecord();" />
Also I tried to solve it by C#
By both ways(either by javascript or by C#)New Row is added in gridview
But when I select question from ddlquestion then page is loaded and and the inserted row in gridview disappears
I am using asp.net 2.0 with C#
