Hello,
I'm new in sorting and not sure how to write the sorting code in order to sort list view by clicking column headers.
I have list view with several columns in my WPF application.
I want to sort list view by clicking any column header.
The list view is populated with data from database using data binding in this way:
List<TestName> lstTestNames = client.GetAllTestNames().ToList();
lstvTestNames.ItemsSource = null;
lstvTestNames.ItemsSource = lstTestNames;
The columns are as usual, ID, string data, date/time date and so on.
The XAML code looks as follows:
<ListView Name="lstvTestNames" Height="360" HorizontalAlignment="Left" Margin="20,33,0,0" VerticalAlignment="Top" Width="465" SelectionChanged="lstvTestNames_SelectionChanged">
<ListView.View>
<GridView>
<GridViewColumn Width="50" DisplayMemberBinding="{Binding Path=test_name_id}">
<GridViewColumnHeader Name="Sort1" Click="GridViewColumnHeader_Click">ID</GridViewColumnHeader>
</GridViewColumn>
...
The sorting code should be in click handler:
private void GridViewColumnHeader_Click(object sender, RoutedEventArgs e)
{
GridViewColumnHeader column = sender as GridViewColumnHeader;
...
}
But, how does it look like?
One additional question. If I want to sort list view by ID column that contains IDs from database,
I suppose all those values are strings (maybe not?).
But, I need integer values. How to handle this?
Thank you in advance.

Take a look at the sort()[^] method of the class.
I must get a clever new signature for 2011.

As I can see Sort method for WPF list view doesn't exist.

Well there seem to be lots of suggestions here[^].

Thank you very much, but I've already checked them and nothing simple was there. So, it means, I haven't found what I'm looking for. I would be thankful if somebody can write some code here.
Thank you in advance.

Well I've just been reading the article in the first link on that page, and it seemed pretty simple to me, even though I am not a WPF expert.

I don't think that's going to happen.

Surprisingly, sorting ListView in WPF is not a simple problem. It requires you to write lots of code. And I mean lots of code[^]!
I suggest that if you are not restricted to older (i.e. pre-4.0) versions of WPF, try using DataGrid instead of ListView. It is a lot more powerful - for one, it gives you sorting for free, and it does not take too much effort to learn if you know ListView. In one of our projects, I replaced several ListView objects and added editing to one of them in about a day.

It's not really complicated,
using System.ComponentModel
ICollectionView view = CollectionViewSource.GetDefaultView(lstvTestNames.ItemsSource);
view.SortDescriptions.Add(new SortDescription("test_name_id", ListSortDirection.Ascending));
|
|
|
|
|
This solved my problem.
Thank you very much.

That would be a pretty cool form generating tool. Have fun with that

On binding large volume of data (say 1500 - 2000) row in Silverlight datagrid.. It throws error.
Does the datagrid has a maximum limit.

Throw us a bone here. What error gets thrown? When you post a question about an exception, it's generally useful to say what the exception is so that we can help, otherwise we are just going to be randomly guessing.

Hi Pete..
Thanks again..
But one other query : does the SL datagrid has any limit on its maximum record size..
Santhosh
|
|
|
|
|
No. The only limit you'll run into with the datagrid is memory.
|
|
|
|
|
No the SL Datagrid does not have a maximum limit.
The funniest thing about this particular signature is that by the time you realise it doesn't say anything it's too late to stop reading it.

Hey Guys,
I've written a few silverlight apps thus far primarily using RIA services and the entity framework. We're currently looking at marrying some of our ruby on rails applications possibly through exposed web services and comsuming those services with silverlight. I've found some examples mainly using iron ruby which seems to be shelved for the time being. My question is, has anyone tried this? Is it possible to consume ruby on rails services via silverlight possibly just through consuming a rest service? I really appreciate your thoughts and opinions as we're evaluating options.
Regards,
Ryan

Hi,
I'm not sure if this is a repost but since I could't find a reference to this video I found and replicated to see if it worked (it did) I want to post a link to this MVVM in WPF and Silverlight
sample (8 video sessions in total) that I think can be of great help for those who don't know this sample and are trying to get MVVM working.
When recreating this sample (source code is available for download) it's important to think about the using directives since it's not alway's clear that these are added while watching the video.

With friendly greetings,

It might be more helpful if you post this as a tip/trick rather than in the question answer forum.
It will get lost here.

Getting this Error in Visual Studio 2008 Silver Light Application
Attempted to read or write protected memory. This is often an indication that other memory is corrupt.
when Clicking on the Page of the Project any suggestion/help will be appreciated

This error appeared randomly back when I was using VS 2008, but now that we switched to VS 2010 the problem never re-appeared.
This is nearly certainly an internal exception of VS 2008, so it has nothing to do with what you are doing. Some people report this error[^] when there is mismatch in Silverlight versions (3 vs. 4). Some people report fixing a similar problem by resetting import/export settings[^], but I don't know if it is going to work for you.
