ListView.ItemContainerGenerator and grouping




I'have the same problem that RoboMoose, last week...

I'm trying to use the ItemContainerGenerator.ContainerFromItem() function to get the container associated with a value in my ListView.

This works fine when binding the Source of the list view with a CollectionViewSource.

I can sort and group, it still work ...

But when I try to set a style on my group, ContainerFromItem() returns null.


Can you help me ?


I'have a small project that I can send you

Thanks a lot

How to check CheckBox.IsChecked property if CheckBox is in header of ListView/GridView with grouping


Sorry for this difficult title :P

So what exactly I need? I will try to explain it step by step as easy as possible.
My question is on the end of this post, but to understand my issue is better to read all steps.

First have a look on this post http://msdn.microsoft.com/en-us/library/ms754027(v=VS.90).aspx

1) I am implementing allmost the same code. 
But I changed one TextBlock (in Expander.Header) for a CheckBox:

<ListView x:Name="ExampleListView"
 ItemsSource="{Binding Source={StaticResource Src}}"

 <GridViewColumn DisplayMemberBinding="{Binding Path=PropertyOne}" Header="One" />
 <GridViewColumn DisplayMemberBinding="{Binding Path=PropertyTwo}" Header="Two" />


Outlook style listview grouping



   I'm new to WPF and need some helps.

   Basically, I want to create a outlook style grouping which the group header can be select/multi-select. For example:

+/- Today   <- Group By Date header


   On Outlook, I can highlight the Group By header and delete all messages inside the group.

   I tried to use Listview with expander control, it looks very similar but I couldn't get the Expander to be selected (Hightlight)?

   Does anyone have sample I can look at?



Playing with Linq grouping: GroupByMany?

One of its features is grouping. Many people understand grouping like it is defined in Sql. Linq is implementing grouping quite the same way. Let's discover this syntax and how to make consecutive groups easier.

Grouping Gridview with jquery

The requirement of the project is to show a table of data with the riskdetails(just for assumption) which have the corresponing values for every month and people used to compare the values for last months.

Building a grouping Grid with GridView and ASP.NET AJAX toolkit CollapsiblePanel

I've posted an update to this post to apply on demand loading of Details data using ASP.NET AJAX PageMethods. I'm demonstrating the usage if CollapsiblePanelExtender client events on the new post. Check it out.

I admit, Matt Berseth is really inspiring me! Few days ago I pass through 2 of his great posts:

.Surrounding your Data Table and Dialog Controls with ComponentArt Styled Panels
.Building a Grouping Grid with the ASP.NET 3.5 LinqDataSource and ListView Controls
The first one is pure design tips one which I used for making good presentation of my demo here. The 2nd post is actually the idea.

Using ASP.NET 3.5's ListView and DataPager Controls: Displaying Data with the ListView

Prior to ASP.NET 3.5, developers who needed to display a set of records could choose between the GridView, DataList, and Repeater controls. The GridView provides rich data features, but has a very boxy layout; the DataList and Repeater allow for a more flexible layout, but lack the "point and click" data features found in the GridView, DetailsView, and FormView controls. The ListView bridges the gap between layout flexibility and built-in data features.

This article, the first in a series of articles on the ListView and DataPager controls, looks at the ListView's many available templates and illustrates how to display data. Read on to learn more!

WPF Tutorial - Using The ListView, Part 1

Many of the controls in WPF have a downright dizzying array of capabilities and features, due in large part to the composibility of all the components. The ListView control is a great example of this - the possibilities are almost endless. This series of tutorials on the ListView will hopefully make the space of possible options seem not quite as daunting

How to listen to events within a listview



I've got a listview and I've put a button control in one of the columns, I'm trying to figure out how I have listen to the button click within a certain row, but can't see the button in the dropdown for the IDs I can generate events for.

I'd like to get the primary key of the row that's been clicked on and then run a sql statement against it.

Any help would be appreciated.

ListView DataPager with SQL-Statements that already return only paged data.



As far as I understand the ListView-Control and the DataPager-Control, they work like this: The ListView gets its datarows from its data source, then the DataPager causes the ListView to display only a subset of those rows.

So what, when I want to use custom databinding for the ListView, that *already* gets the certain subset from SQL-Server (for better performance). Can I and how can I use the DataPager then?

Thanx, S.

Programmatically Simulating the ListView's ItemCommand Event


I have a User Control that contains a ListView.  In the user control's code is this event handler:

    protected void listView1_ItemCommand(object source, ListViewCommandEventArgs e)
      Button_ClickHandler(source, e);

What's occurring is that I'm explicitly firing an event so that the parent web page can monitor this and take appropriate actions.  Thus when the user clicks on a different ListViewItem it triggers the population of associated data elsewhere on the web page.

This all works fine except for one thing: When I first load the control I'm pre-setting the first ListViewItem.  Unfortunately, just setting the ListView's SelectedIndex = 0 doesn't fire the aforementioned event handler.

So I started investigating how to call "listView1_ItemCommand" but couldn't figure out how to instantiate the "e" parameter.

Any ideas of how to resolve this?


Dropdownlist in ListView


I have a transaction table with a field called product. There is a limited number of choices for product so I also have a product table. I am showing the transactions in a ListView with a dropdownlist for Product. The field Product can be blank (all works well then). The user can leave the field blank or they can choose from the dropdownlist. I am running into a problem with the dropdownlist in the Edit Template. No matter what the product is in the transaction file, I get a page error of "ddlEditProduct has a SelectedValue which is invalid because it does not exist in the list of items". I have verified the product does exist in the product table.

My markup is:

<asp:DropDownList ID="ddlEditProduct" runat="server"
SelectedValue='<%# Bind("Product") %>' >
<asp:ListItem Selected="True"></asp:ListItem>

Manually coding controls such as gridview, listview, repeater, etc.


using vs2010 and .net 4

In my project I have a separate DAL built from class files that I'd like to use to store my code for CRUD operations against my database.

I'm having a hard time finding examples of how to code server controls like the gridview, listview, repeater etc., for CRUD operations manually, i.e., without a datasource control of some flavor.

I don't have any problem manually coding the referenced controls to get my data, but I do have problems when it comes to coding them to perform CRUD operations unless I use a datasource control. When I use the datasource controls CRUD operations seem to automagically appear out of nowhere after they're configured.

Can someone point me to some samples somewhere? Have I missed a section at MSDN?

listview 3.5 bind dropdownlists edit item template VB.NET


I am trying to do this with many issues of data binding doubling the amount and not setting selectedValue on dropdownlist. I have read some posts and they help but I am missing a crucial piece. My problem is that my dropdownlist is doubling the amount of records for the dropdownlist. Instead of "YES;NO;SELECT A VALUE", I am getting "YES;NO;SELECT A VALUE;YES;NO;YES;NO". My database is correct with the UPDATE part but the rebind after update is failing horribly.

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        If IsPostBack Then
            If Session("ACTIVETAB").ToString() = Session("SUBCONTRACTSATABNO").ToString() Then
            End If
        End If
    End Sub

    Public Function loadlookups(ByVal id As String, ByVal e As System.Web.UI.WebControls.ListViewItemEventArgs) As DataTable
        Select Case id
            Case "ddlCertReceived"
                dt = GetLookupTable("SubcontractsA", "Sub 1 Cert Received")
                Dim ddlCertReceived As DropDownList = _
                CType(e.Item.FindControl("ddlCertReceived"), DropDownList)
                ddlCertReceived.DataSource = dt
                ddlCertReceived.DataTextField = "lup_text"
