Re: Using ListViewItem in WPF ?

30-Dec-09 9:03

Hi.
I've written the following XAML code for my ListView :

<ListView x:Name="ListView1" Background="#FFEEF3FA" >
    <ListView.View>
        <GridView>
            <GridViewColumn x:Name="GridViewColumnName" Header="Name"  Width="200" />
            <GridViewColumn x:Name="GridViewColumnTags" Header="Tags" Width="100" />
            <GridViewColumn x:Name="GridViewColumnLocation" Header="Location" Width="238" />
        </GridView>
    </ListView.View>
    <ListViewItem>test1</ListViewItem>
    <ListViewItem>test2</ListViewItem>
    <ListViewItem>test3</ListViewItem>
    <ListViewItem>test4</ListViewItem>
    <ListViewItem>test5</ListViewItem>
    <ListViewItem>test6</ListViewItem>
    <ListViewItem>test7</ListViewItem>
    <ListViewItem>test8</ListViewItem>
    <ListViewItem>test9</ListViewItem>
    <ListViewItem>test10</ListViewItem>
</ListView>

You can see the result of above code in this image : http://xs.to/image-CB3E_4B3BAE1D.jpg[^]

I wanna create a ListView with ListViewItem in XAML code like this : http://xs.to/image-7BBC_4B3BB199.jpg[^]

I don't know how I should do it !
Would you please guide me ?
Thanks in advance.

First, create a class that holds 3 properties:

using System.Windows;
namespace WpfApplication1
{
	public partial class Window1 : Window
	{
		public Window1()
		{
			InitializeComponent();
		}
	}
<big><big><big>	public class MyClass
	{
		public string Prop1
		{
			get;
			set;
		}
		public string Prop2
		{
			get;
			set;
		}
		public string Prop3
		{
			get;
			set;
		}
	}</big></big></big>
}

Next, you can define an array in your XAML then set that as your ItemsSource on your ListView. Then you use the DisplayMemberBinding property of each GridViewColumn to decide what you want to display in each column:

XML

<Window x:Class="WpfApplication1.Window1"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
<big><big><big>    xmlns:local="clr-namespace:WpfApplication1"</big></big></big>>
<big><big><big>    <Window.Resources>
        <x:Array x:Key="SomeData" Type="{x:Type local:MyClass}">
            <local:MyClass Prop1="test1" Prop2="test2" Prop3="test3" />
            <local:MyClass Prop1="test4" Prop2="test5" Prop3="test6" />
            <local:MyClass Prop1="test7" Prop2="test8" Prop3="test9" />
            <local:MyClass Prop1="test10" />
        </x:Array>
    </Window.Resources></big></big></big>
    <Grid>
        <ListView <big><big><big>ItemsSource="{StaticResource SomeData}"</big></big></big>>
            <ListView.View>
                <GridView>
                    <GridViewColumn <big><big><big>DisplayMemberBinding="{Binding Prop1}"</big></big></big> Header="Name" Width="50" />
                    <GridViewColumn <big><big><big>DisplayMemberBinding="{Binding Prop2}"</big></big></big> Header="Tags" Width="50" />
                    <GridViewColumn <big><big><big>DisplayMemberBinding="{Binding Prop3}"</big></big></big> Header="Location" Width="50" />
                </GridView>
            </ListView.View>
        </ListView>
    </Grid>
</Window>

If you REALLY want to specify each ListViewItem rather than setting the ItemsSource, then you could use this XAML instead:

XML

<Window x:Class="WpfApplication1.Window1"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="clr-namespace:WpfApplication1">
    <Grid>
        <ListView>
            <ListView.View>
                <GridView>
                    <GridViewColumn <big><big><big>DisplayMemberBinding="{Binding Prop1}"</big></big></big> Header="Name" Width="50" />
                    <GridViewColumn <big><big><big>DisplayMemberBinding="{Binding Prop2}"</big></big></big> Header="Tags" Width="50" />
                    <GridViewColumn <big><big><big>DisplayMemberBinding="{Binding Prop3}"</big></big></big> Header="Location" Width="50" />
                </GridView>
            </ListView.View>
            <ListViewItem><big><big><big><local:MyClass Prop1="test1" Prop2="test2" Prop3="test3" /></big></big></big></ListViewItem>
            <ListViewItem><big><big><big><local:MyClass Prop1="test4" Prop2="test5" Prop3="test6" /></big></big></big></ListViewItem>
            <ListViewItem><big><big><big><local:MyClass Prop1="test7" Prop2="test8" Prop3="test9" /></big></big></big></ListViewItem>
            <ListViewItem><big><big><big><local:MyClass Prop1="test10" /></big></big></big></ListViewItem>
        </ListView>
    </Grid>
</Window>

Excellent, Thanks aspdotnetdev.
I'm gonna to put an Object into the Property instead of string !
e.g : I want to put a StackPanel that contains an Image and a Label in Prop1.
What should I have done ?

Thanks in advance.

Use CellTemplate rather than DisplayMemberBinding.

Also, I highly recommend downloading the WPF Toolkit to use the DataGrid rather than the ListView. The DataGrid makes customizing visuals much easier. I believe it also has some additional options for sizing columns (percent, auto, etc.). You might also look at this quick stack overflow discussion of the advantages of using DataGrid.

Getting click location

Jeroen De Dauw30-Dec-09 5:44

Hey,

I want to have some surface on which the user can click, after which I get the coordinates so I can store them somewhere, and draw something on that location.

I've found ways to let a user draw on something, but not how to effectively get the coordinates. This is vital for the application I want to create though.

This is a C# application working with .Net 4.0 beta 2 and a WPF interface.

Any pointers or suggestions in the good direction are welcome - I really want to start with the real work on that app Smile | :)

Cheers!

When handling mouse events, you can use the GetPosition() method
on the MouseEventArgs/MouseButtonEventArgs object to get the
coordinates relative to an element.

You can also use System.Windows.Input.Mouse.GetPosition() to
get the current coordinates relative to an element.

Hey guys,

I did search for such a method, and didn't find one. Guess why...

Somehow I managed to click the KeyDown event instead of the MouseDown one OMG | :OMG:

Anyway, thanks for the helping Smile | :)

Cheers!

I'm probably doing something stupid wrong here, but my event handler for the MouseDown event is not getting called when I click on my canvas. Anyone an idea what I'm messing up?

Curious if I'm failing at C# or at WPF here Smile | :)

Hi all,

I am making use of a DataForm to display my data. I have made use of the DataForm edit template to customize the layout of the form. Data is returned and is being displayed within the DataForm. The problem is that, as soon as I start navigating (2 navigation clicks) with the DataFrom, only the ComboBox 'looses' it's binding on the SelectedItem (although it's selected item was data bound and then it just goes blank Confused | :confused:

).

The back end code consists of a generic list List<string> and a string variable that has the value of each data item that is returned.

..
public List<string> Category { get; set; }
public string CategoryName { get; set; }
..

The XAML code:

...
<dataFormToolkit:DataField DescriptionViewerPosition="Auto" LabelPosition="Left" LabelVisibility="Visible" Label="Category">
    <ComboBox ItemsSource="{Binding Category}"  SelectedItem="{Binding CategoryName, Mode=TwoWay}" />
</dataFormToolkit:DataField>
...

Any reason why this is happening and how I can fix it?
Many thanks in advance.
Kind regards

Hey. This problem has been bugging me a lot lately - Something really odd is happening in the framework. What's happening is the data field control is modifying the bindings on the control and re-setting them. Setting the SelectedItem works fine, but when it comes to re-set the ItemsSource property the binding for the *SelectedItem* property *vanishes* without a trace.

The only workaround I have at the moment is to make the ItemsSource binding TwoWay, and ensuring that the property it's bound to is read-only. This stops the code from modifying the ItemsSource binding.

However, I'm now finding that the bindings are disappearing under other circumstances as well (it looks like it's happening occasionally when there is more than 1 combo box in the form) - I haven't solved that one yet.

Cheers,
Mike

WndProc equivalent in WPF?

Is there a single method in WPF that can handle all types of input at once, like WndProc in Windows Forms? Or do I have to capture and forward each event separately?

Thanks for your reply.

Of course, it should do the job. Anyway, it seems to be a pretty strange work-around. You're provided with dozens of overridable methods for handling input, but you have to use native hooks...

That's the way the ScrollViewer is designed to work.
The ScrollViewer uses a fixed-size viewport to view a
portion of the scrollable content.
