I've looked at a bunch of different controls(ListView, GridView, etc.) and can't decide which makes the most sense for me to use.
I want something that looks and functions just like a listBox with the ability to select a row with a single click, except it would contain data with multiple columns.
I'm just looking for suggestions on which control to use and how I would go about having it select a row(whether it's a selectionMode or an onClick function or what). Since I'm new to these controls I'd like some direction on which tag to place those selection options, I think I can figure out the rest however.
Thanks :)
I like using the ListView that contains a GridView as it's view. Here's how I defined it in XAML:
<ListView Name="lstCurrentInvoices" Grid.Row="4" Margin="0,0,0,0" SelectionMode="Extended" ToolTip="Invoices included in invoice file." IsTabStop="True" TabIndex="8">
<ListView.View>
<GridView>
<GridViewColumn Width="40" Header="ID" DisplayMemberBinding="{Binding ClientId}"/>
<GridViewColumn Width="170" Header="Name" DisplayMemberBinding="{Binding ClientName}"/>
<GridViewColumn Width="80" Header="Date" DisplayMemberBinding="{Binding InvoiceDate}"/>
<GridViewColumn Width="40" Header="Frequency" DisplayMemberBinding="{Binding Frequency}" />
</GridView>
</ListView.View>
</ListView>
This way you kind of get the best of both worlds. In this example, you can have multiple rows selected. You can detect which rows have been selected and grab the objects from you data source. It's really quite powerful. Hope this helps

Ì want to write a software where there is a grid layout inside a scrollview.
I already hardcoded it, but I think I need to find a solution to make this dynamic! How can I manage to do this! I am pretty new to C# and WPF. I post a screenshot and my code so you can see what I am trying to achieve.
DataGrid is probably the best thing to use here, although you can also do it with a ListView using a GridView as the view:
<ListView ItemsSource="{Binding Items}">
<ListView.View>
<GridView>
<GridViewColumn Header="Name" DisplayMemberBinding="{Binding Name}" />
<GridViewColumn Header="Age" DisplayMemberBinding="{Binding Age}" />
<GridViewColumn Header="Gender" DisplayMemberBinding="{Binding Gender}" />
</GridView>
</ListView.View>
</ListView>
I have an application which is check the incoming Mails on the Server and refresh a List with X-Values in it. Now I want to Plot the incoming Mail count in a Live Chart. I use http://lvcharts.net for this.
I have two classes a Mail Object with the Count and a TimeStamp in it and a List Class with all Mail Objects in it.
Here is my sample(pseudo) XAMl code:
<liveCharts:BarChart Name="MailChart" Grid.Row="1" Grid.Column="0">
<liveCharts:BarChart.Series>
<liveCharts:BarSeries Title="Mails" Values= "{Binding MailCountList.Count}"></liveCharts:BarSeries>
......
......
<liveCharts:BarChart.AxisY>
<liveCharts:Axis Title="Time" Labels="{Binding MailCountList.Timestamp}">
......
The Objects are in a normal List with automatically Refesh I use MVVM.
My Question is:
How can I bind a List to a XAML Value Series ?
I have used an ObservableCollection to view the Content and a normal list to fill sort etc. the Xaml Code Looks Like:
<ListView ItemsSource="{Binding TableList}" Grid.Row="0">
<ListView.View>
<GridView>
<GridViewColumn Width="50" Header="ID" DisplayMemberBinding="{Binding ID}"/>
<GridViewColumn Width="180" Header="Name" DisplayMemberBinding="{Binding Name}"/>
<GridViewColumn Width="100" Header="Group" DisplayMemberBinding="{Binding Group}"/>
<GridViewColumn Width="85" Header="Version" DisplayMemberBinding="{Binding Version}"/>
</GridView>
</ListView.View>
</ListView>
The Source of the ListView is in the ItemSource and to Display Multiple Rows I use GridViewColumn with Binding to the Object Values from the List in "DisplayMemberBinding"
I am experiencing very poor performance with a ListView in WPF, using around 30000 records. As far as I know Virtualisation should be turned on as this is the default (I even turned it on explicitly in the XAML).
The poor performance manifests in this way:
Very slow (a couple of minutes) to do the initial bind
Very slow (over a minute) scrolling
Very slow (again, well over a minute) when you select a row.
I was hoping someone would take a look at the XAML and let me have some thoughts.
<ListView Name="grdComms" Grid.Row="0" Grid.Column="0" SelectedItem="{Binding SelectedHeader}"
VirtualizingStackPanel.IsVirtualizing="True" VirtualizingStackPanel.VirtualizationMode="Recycling"
ScrollViewer.IsDeferredScrollingEnabled="True">
<ListView.View>
<GridView >
<GridViewColumn Header="Account Name" DisplayMemberBinding="{Binding Path=AccountName}" Width="150" />
<GridViewColumn Header="Account Number" DisplayMemberBinding="{Binding Path=AccountNumber}" Width="120" />
<GridViewColumn Header="Type" DisplayMemberBinding="{Binding Path=Type}" Width="80" />
<GridViewColumn Header="Delivery" DisplayMemberBinding="{Binding Path=Delivery}" Width="80" />
<GridViewColumn Header="Count" DisplayMemberBinding="{Binding Path=RequestCount}" Width="80" />
<GridViewColumn Width="80" Header="DeDupe">
<GridViewColumn.CellTemplate>
<DataTemplate>
<StackPanel Width="80">
<CheckBox HorizontalAlignment="Center" IsChecked="{Binding Path=SelectedForProcessing, Mode=TwoWay}"/>
</StackPanel>
</DataTemplate>
</GridViewColumn.CellTemplate>
</GridViewColumn>
</GridView>
</ListView.View>
</ListView>
Note: the ItemsSource is set in code, to an ObservableCollection. This is a collection of pretty plain properties (couple of strings, a bool), which is a ViewModel onto the Model, which is (again) strings and bools.
I'm reading where people are using large record sets with no problems, but the various things I have tried don't seem to work.
Any more information required please let me know.
Please ignore me. The problem entirely disappears as soon as I set the MaxHeight of the ListView to something bigger than it needs. I would swear blind I tried this, obviously not.
Move along, there is nothing to see here ...

I'm trying to create a Table inside a FlowDocument inside a FlowDocumentPageViewer, as seen in this tutorial. I've never created a table in WPF before, and I was expecting there to be an ItemsSourceproperty to which I could bind, like with a ListBox. I want to customize the template for each row, and I want each row's source to be an item in a collection that I pass to the entire table. So I'll have a List<MyClass> instance that would be passed to the table, and each row would show a single MyClass. How can I do that? Do I not want to use a Table within a FlowDocument? The reason I wanted to use some kind of tabular format is so that I can have a single row of column names that applies to all the rows.
I think what I wanted was to use ListView, thanks to this tutorial:
<ListView Grid.Row="0" ItemsSource="{Binding Path=MyList}" MinWidth="400"
MinHeight="200">
<ListView.View>
<GridView>
<GridView.Columns>
<GridViewColumn
DisplayMemberBinding="{Binding Path=MyFirstField}"
Header="First Field"/>
<GridViewColumn
DisplayMemberBinding="{Binding Path=MySecondField}"
Header="Second Field"/>
</GridView.Columns>
</GridView>
</ListView.View>
</ListView>
How can I make a ListView imitate the ListView in Windows Explorer on the right side. Like how can I get icons in the ListView and get the arrows?
You can find the icons by using Google Image search. To create the ListView, you could do something like this is XAML:
<Grid>
<ListView ItemsSource="{Binding ListViewSource}">
<ListView.View>
<GridView>
<GridViewColumn Width="25">
<GridViewColumn.CellTemplate>
<DataTemplate>
<Image Source="{Binding Icon}"/>
</DataTemplate>
</GridViewColumn.CellTemplate>
</GridViewColumn>
<GridViewColumn Header="Name" DisplayMemberBinding="{Binding FileName}" Width="250"/>
<GridViewColumn Header="Date Modified" DisplayMemberBinding="{Binding DateModified}" Width="100"/>
<GridViewColumn Header="Type" DisplayMemberBinding="{Binding FileType}" Width="100"/>
<GridViewColumn Header="Size" DisplayMemberBinding="{Binding FileSize}" Width="100"/>
</GridView>
</ListView.View>
</ListView>
</Grid>
The next step is to create an ObservableCollection to hold all of the items in your list and call it ListViewSource. You can populate this collection with actual FileDirectory information, or your own kind of list. You'll then want to create your logic as to what happens when you doubleclick on an item. Since your question didn't specify to what detail you want the ListView to work, I'm going to stop there. Let us know if you want it to behave just like Windows Explorer, and we'll try to help you out.
