I'm hoping to dynamically change the number of columns in my ItemTemplate of my ListView:
<asp:ListView runat="server" ID="ReportListView" DataSourceID="ReportListViewSDS">
<LayoutTemplate>
<table>
<tr>
[code].....
I have the following code. It works as is, but... I am not always going to have an even number of items in the RSS feed So, at the end of the table, I might have only one table cell on the last row. So, is there a way to count the number of ItemTemplates and AlternatingItemTemplate, so if it is an odd number I would be able to add another cell <td> </td></tr> and close the table row?
[Code]...
How can I create alternating background colors for listview rows while only using ItemTemplate? I don't want to use AlternateTemplate because I would have to edit both of them everytime I want to change something when all I'm using it for is to create the alternating background colors. So what's a way I could do it using only the ItemTemplate?

I have a page of checkboxes, I select a few of them, click submit, and go to a second page. on this page, I have a listview that is built using the checkboxes selected on the previous page. Now I'm wondering how i can add sortability to this listview.
In the past I would add CommandName='sort' CommandArgument='column' to the link on the header in the LayoutTemplate. But since my listview has it's header row outside of the listview, this doesn't seem to work. This is what I have so far:
<!-- header row (outside of listview, when I try to put it as a LayoutTemplate in listview i get an error, see below) -->
<table>

I've tried to add a templatelayout in the listview, but that gives me an error on the line that binds the data (listview.databind() ), i'm assuming because this isn't possible.
get a sortable header row on this listview?
How do I set ListView data through the codebehind instead of using the Bind() function in the Text attribute?Right now I'm doing the following, but I'd like to have it retrieved and set in the codebehind. I'm using VB..
<asp:Label ID="Date" runat="server" Text='<%# Bind("Date") %>'></asp:Label>
Edit: I'm binding the data in the following way with a DataTable.
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If Not IsPostBack Then
ListView.DataSource = MyDataTable

In my application, I have been getting this error each time the treeView loads it's items. This error makes my application slow on load and takes at least two minutes to load.The error is: System.Windows.Data Error: 26 : ItemTemplate and ItemTemplateSelector are ignored for items already of the ItemsControl's container type; Type='TreeViewItem'
My xaml code for the treeview is: (I'm using VB.net on my ViewModel)
<TreeView ScrollViewer.VerticalScrollBarVisibility="Hidden"
ItemContainerStyle="{DynamicResource tviStyle}"
Background="#FFF0F0F0" BorderBrush="#FFE5E2DB"

The binding of the ItemsSource is an ObservableCollection(Of TreeViewItem) thats is filled from a database.

I have a gridview where each columns have two template fields. One is ItemTemplate and another is EditItemTemplate. Now in EditItemTemplate it will show some textboxes where i can perform necessary editing. I can easily fetch data from each cell by using the following code-
[code]...
But how can i fetch data when the grid view is not in editing mode that is in ItemTemplate. I have tried the following-
[code]...
But its getting the exception object reference is not set to an instance of object. This is probably happening because the above code should be used in a method like RowDataBound when a row is instantiated. But I have to fetch data from some other method.Again for clarification I want to fetch data when the gridview columns are in ItemTemplate Mode.
I use Visual Web Developer 2008 Express.I have Label1 in a DataList ItemTemplate. I wish to use a button to get the text from that label and add it to text in TextBox1 which is elsewhere on the page.
I know how to do this from a standard label on a ASP.NET web page but cannot work out how to get the text from a label inside a DataList ItemTemplate.
This is what I thought I should do Protected Sub submit_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles submit.Click
TextBox1.Text = TextBox1.Text & " " & DataList1.ItemTemplates.ItemTemplate.Label2.Text
End Sub
I thought that because DataList1.ItemTemplates.ItemTemplate.Label2 - System.Web.UI.WebControls.Label is what is written in the properties window header when I select the label in the DataList template.
When I try that, I get a Blue Squiggle under "DataList1.ItemTemplates" and if I hover over the squiggle the error box comes up saying " 'ItemTemplates' is not a member of 'System.Web.UI.WeControls.DataList'

I have a gridview as shown below. When the EmpType is contract the EmpID must be masked as "XXX"; for regular employees, actual EmpID should be shown. Also, when it is masked, I need to add a button control in the EmpID column.I need to do it using mark-up; not using code behind. How can we write the conditional logic for Gridview's ItemTemplate for this logic?Note: .Net 4.0

ListView allows the use of LayoutTemplate - but I didn't see any examples that insert this kind of code in LayoutTemplate. And inserting this code in LayoutTemplate would result in an error.DetailView allows to produce code automatically but I'd like to use a specific design (for ex. using "fieldset" that encompasses some fields).
Okay, so I wrote a few custom ItemTemplates for VS2010 that implement IWizard in VB.NET (4.0). Straight forward enough. They work during my testing, but when someone else deploys and attempts to use any of them, Visual Studio throws an incredibly generic Exception has been thrown by a target of invocation error.
Stranger still, after they open up the project properties and try again... they work. Without changing anything. Anyone have any clue what is going on? Or perhaps even just a way of getting VS to give me a more specific error? I already tried devenv.exe /log but nothing out of the ordinary was there.
