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!

ListView Not Displaying Any Items

Hi All,   I have a ListView that has 2 columns (Key | Value). The ListView is bound to a DataContext, and each column is bound to a property off the DataContext. Here's the code:   <UserControl.Resources> <CollectionViewSource x:Key="WorkflowViewSource" Source="{Binding Arguments}"/> </UserControl.Resources>     <ListView DataContext="{StaticResource ResourceKey=WorkflowViewSource}" ItemsSource="{Binding}"> <ListView.View> <GridView AllowsColumnReorder="True"> <GridViewColumn Header="Name" DisplayMemberBinding="{Binding Key}"/> <GridViewColumn Header="Value" DisplayMemberBinding="{Binding Value}"/> </GridView> </ListView.View> </ListView>   The Arguments property is a public ObservableCollection<MyType>, and I've verified that it is indeed populated with items (11 of them in-fact). The properties are set on each item. The problem is my ListView is empty. I've switched to a ListBox as well and nothing. I've never had a problem like this before and I'm at a loss as to what could be causing it.   Let me know if you need any info.   Edit: I've verified the output window of Visual Studio and the binding to Arguments is correct. I know i

Displaying a count of records in a Data View Web Part outside the web part itself?

I have a DVWP with 400 rows. I have these inside a Div tag, which makes it scrollable. I also have several URL filters set up to show certain records. I would like to add the count to the page to display the number of records when the filters are activated. I have added the View Footer to the DVWP but this just gets placed at the bottom (still inside the Div tag). It would also be cool to be able to do counts with criteria so I could do comparisons (ie, 50 records overdue/400 total etc). Thanks

ListView Not Inserting Records


Hi all,

Here's the next instalment of my asp.net data access nightmare!

I've got a listview on my page, and when I run the page it correctly displays the data that it should.  However, when I add data into the empty new record and hit the 'Insert' button the page posts back but the record isn't inserted.  Annoyingly, I don't get any error!

The listview's datasource has an INSERT command and insert parameters specified.  The button seems to be triggering the listview's insert method because the ItemInserting event fires.

With no error message to go on I'm struggling to figure out what the problem is.  I have a feeling it's something to do with the makeup of the page.  The listview in question is nested within an Accordion control and the listview's data source isn't set until runtime, when it's done in the ItemDataBound event of the Accordion control.  As I say, though, it does RETRIEVE data correctly, it's just the inserting that's a problem.

I created a new, blank page with just this listview on it using the same code but not nesting it within any other control and hardcoding the datasource instead of setting it at runtime and that works perfectly, so I'm confident that my INSERT command, insert parameters and so forth are correct.

displaying 2 alternating db records with each new page load event


I have a webpage which displays content drawn from a single record in a database table. I've been asked to change this so that the content displayed alternates between 2 records each time the page is requested by a browser (I guess this would equate to each PageLoad event).

The records to be displayed are chosen on the basis of two dates, a beginning date and and ending date, that define a time period in which the record is to be active. The table containing these records has 2 columns containing these dates (begin date is contained in "dtDisplay" and end date is "lastDisplay."

I'm not sure how to amend the existing code behind to make this happen. Here is the c# that I inherited from a developer who is no longer available. Thanks for any help:

private void getfeatured_properties()
           string today = DateTime.Now.Date.ToString();

           SqlCommand cmd = common.openDatabase();
           if (cmd.Connection.State == ConnectionState.Open)
                 string sql = "select propID from featured_properties where " +
                    "dtDisplay <= '" + today + "' and " +
                    "lastDisplay >= '" + today + "'";

Displaying SharePoint lists in Web Parts

When you create a built-in or custom list in Microsoft Windows SharePoint Services, Windows SharePoint Services creates a Web Part, a basic building block of a SharePoint site, to display that list. These Web Parts are called List View Web Parts. Windows SharePoint Services stores List View Web Parts in the site collection Web Part gallery. (The site collection Web Part gallery is the most central gallery of Web Parts for a work group. By default, the gallery name is the name of the site, such as "Our Team Site Web Part Gallery." )

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.

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.
