Thank you for your help. I tried several things but no good result.
You can define an ItemContainerStyle that would set your tooltip template and content.
See an example below, here I define an UniformGrid to display multiple text lines in one column. You are free to setup your tooltip as you wish. You still need to tell the view which data properties need to be displayed in the tooltip.
<ListView ItemsSource="{Binding Articulos}">
<ListView.ItemContainerStyle>
<Style TargetType="{x:Type ListViewItem}">
<Setter Property="ToolTip">
<Setter.Value>
<UniformGrid Columns="1">
<TextBlock Text="{Binding CodigoDeBarras}"/>
<TextBlock Text="{Binding Descripcion}"/>
<TextBlock Text="{Binding AnyOtherProperty}"/>
</UniformGrid>
</Setter.Value>
</Setter>
</Style>
</ListView.ItemContainerStyle>
</ListView>

The problem I'm having is that if I generate my ICollectionView (the "View" in ItemsSource="{Binding View}") with a basic CollectionViewSource, everything works as expected. E.g.:
View = new CollectionViewSource { Source = Models }.View;
However, if I use something more complex, the Setter binding of the DataTrigger doesn't work. E.g.:
View =
new CollectionViewSource
{
Source =
Models
.Join(
Lookups
, model => model.ID
, lookup => lookup.Key
, (model, lookup) =>
new ComplexModel
{
ID = model.ID,
Name = model.Name,
Value = lookup.Value
}
)
}
.View;
I get the error:
System.Windows.Data Error: 40 : BindingExpression path error: 'Name' property not found on 'object' ''MainWindowViewModel' (HashCode=17911681)'.
MainWindowViewModel is the overall DataContext (outside of the UserControl), so it's as though the DataContext has not been set.
Why would this be the case?
I will start developing for WPF and I have a doubt.
I created a ListView with the Binding property to the next ExtComandaDTO the object. The property in "seleciona" has relationship with a checkbox, but I have following problem.
When I click the checkbox it calls the normal event, but when I change the value of "seleciona" at runtime checkbox in my listview is selected but does not call the event check.
There is missing from Listview to be called the event some attribute?

Checked and Unchecked are events fired by the UI (not a set).
Handle that stuff in the set if you want to catch changes from code.
I have a ListView box containing TextBoxes that allow users to add and change the content. How do I verify that the content that is changed is not the same as any exiting one in C# behind?
Xaml:
<ListView
x:Name="_regionQueryListBox"
Width="122"
HorizontalAlignment="Left"
VerticalAlignment="Stretch"
DataContext="{Binding}"
IsSynchronizedWithCurrentItem="True"
Style="{StaticResource ListViewRegionSelectorStyle}"
ItemsSource="{Binding Path=Model}"
ScrollViewer.HorizontalScrollBarVisibility="Disabled"
SelectionChanged="_regionQueryListBox_SelectionChanged">
<ListView.ItemContainerStyle>
<Style TargetType="ListViewItem">
<Setter Property="HorizontalContentAlignment" Value="Stretch" />
</Style>
</ListView.ItemContainerStyle>
<ListView.View>
<GridView>
<GridViewColumn Header="Region" Width="{Binding Path=ActualWidth, RelativeSource={RelativeSource Mode=FindAncestor, AncestorType=ListView}}">
<GridViewColumn.CellTemplate>
<DataTemplate>
<TextBox
HorizontalAlignment="Left"
VerticalAlignment="Stretch"
MaxLength="16"
Width="110"
Margin="-2,0,0,0"
Padding="-2,0,0,0"
Text="{Binding Path=RegionName}"/>
</DataTemplate>
</GridViewColumn.CellTemplate>
</GridViewColumn>
</GridView>
</ListView.View>

Yes, it is MVVM. I have a validation for adding same item and you can find the Model like below:
private void OnQueryCollectionChanged(object sender, NotifyCollectionChangedEventArgs args)
{
if (Model.Count == 0)
{
CurrentRegionViewModel = null;
}
if (args.Action == NotifyCollectionChangedAction.Add)
{
RegionQuery addedRegionQuery = args.NewItems.OfType<RegionQuery>().FirstOrDefault();
if (addedRegionQuery != null)
{
string name = addedRegionQuery.RegionName;
while (Model.Any(q => q.RegionName == name && q != addedRegionQuery))
{
name += "*";
}
addedRegionQuery.RegionName = name;
}
}
I need to add a tooltip for a column header of a DataGrid (Silverlight 4). I will generate the number of columns and column header text dynamically.
GridColumnCreation(....)
{
IEnumerable allHeaderText = /* Linq query */;
}
How to use this collection to set a tooltip?
This can be done even more simply than in #Farukh's answer:
<data:DataGridTextColumn.HeaderStyle>
<Style TargetType="DataGridColumnHeader">
<Setter Property="ToolTipService.ToolTipProperty"
Value="Your tool tip here" />
</Style>
</data:DataGridTextColumn.HeaderStyle>
Or, if you need to do it in code:
var style = new Style(typeof(DataGridColumnHeader));
style.Setters.Add(new Setter(ToolTipService.ToolTipProperty,
"Your tool tip here"));
column.HeaderStyle = style;
In case it might help anyone. It works when using TooTip property.
<DataGridTextColumn.HeaderStyle>
<Style TargetType="DataGridColumnHeader">
<Setter Property="ToolTip" Value="{Binding}"/>
</Style>
</DataGridTextColumn.HeaderStyle>
If you do not want to create a new style for the Header, simply add a TextBlock for your column header and set the tooltip on it.
<DataGridTextColumn>
<DataGridTextColumn.Header>
<TextBlock Text="ColumnA" ToolTip="ColumnA Tooltip"/>
</DataGridTextColumn.Header>
</DataGridTextColumn>
This can be done by using DataGridTextColumn & DataGridTextColumn.HeaderStyle. In the headerstyle tag, use the ToolTipService and bind the content to the dynamic values generated. Here's a sample code for this...
<data:DataGrid.Columns>
<data:DataGridTextColumn Header="First Name" Binding="{Binding FName}" >
<data:DataGridTextColumn.HeaderStyle>
<Style TargetType="dataprimitives:DataGridColumnHeader">
<Setter Property="ContentTemplate">
<Setter.Value>
<DataTemplate>
<ContentControl Content="{Binding}">
<ToolTipService.ToolTip>
<ToolTip Content="Tooltip First" />
</ToolTipService.ToolTip>
</ContentControl>
</DataTemplate>
</Setter.Value>
</Setter>
</Style>
</data:DataGridTextColumn.HeaderStyle>
</data:DataGridTextColumn>
<data:DataGridTextColumn Header="Last Name" Binding="{Binding LName}">
<data:DataGridTextColumn.HeaderStyle>
<Style TargetType="dataprimitives:DataGridColumnHeader">
<Setter Property="ContentTemplate">
<Setter.Value>
<DataTemplate>
<ContentControl Content="{Binding}">
<ToolTipService.ToolTip>
<ToolTip Content="Tooltip Second"></ToolTip>
</ToolTipService.ToolTip>
</ContentControl>
</DataTemplate>
</Setter.Value>
</Setter>
</Style>
</data:DataGridTextColumn.HeaderStyle>
</data:DataGridTextColumn>
<data:DataGridTextColumn Header="City" Binding="{Binding City}">
<data:DataGridTextColumn.HeaderStyle>
<Style TargetType="dataprimitives:DataGridColumnHeader">
<Setter Property="ContentTemplate">
<Setter.Value>
<DataTemplate>
<ContentControl Content="{Binding}">
<ToolTipService.ToolTip>
<ToolTip Content="Tooltip Third"></ToolTip>
</ToolTipService.ToolTip>
</ContentControl>
</DataTemplate>
</Setter.Value>
</Setter>
</Style>
</data:DataGridTextColumn.HeaderStyle>
</data:DataGridTextColumn>
</data:DataGrid.Columns>
</data:DataGrid>
</Grid>
where Custdetails.. is something like this..
class Customer
{
public string LName { set; get; }
public string FName { set; get; }
public string City { set; get; }
}
DataBinding...
List<Customer> customers = new List<Customer>
{
new Customer { LName="Alan", FName="Ameen", City="New York" },
new Customer { LName="Forgeard", FName="Steven", City="Mumbai" },
new Customer { LName="Angur", FName="Paul", City="São Paulo" }
};
dgCustDetails.ItemsSource = customers;
This would display the header tooltips... To make it dynamic.. Replace the ToolTip Content with Binding & the desired value...
<ListView ItemsSource="{Binding MyData}">
<ListView.View>
<GridView>
<GridViewColumn Header="col1" DisplayMemberBinding="{Binding Path=value1}">
<GridViewColumn.CellTemplate>
<DataTemplate>
<TextBlock TextAlignment="Right" Text="{Binding Path=value1}"/>
</DataTemplate>
</GridViewColumn.CellTemplate>
</GridViewColumn>
<GridViewColumn Header="col2">
<GridViewColumn.CellTemplate>
<DataTemplate>
<TextBlock TextAlignment="Center" Text="{Binding Path=value2}"/>
</DataTemplate>
</GridViewColumn.CellTemplate>
</GridViewColumn>
<GridViewColumn Header="col3" DisplayMemberBinding="{Binding Path=value3}"/>
</GridView>
</ListView.View>
<ListView ItemsSource="{Binding MyData}">
col1 is supposed to be right-aligned. (Not working)
col2 is supposed to be center-aligned. (Working)
col3 is supposed to be left-aligned. (Working)
Is there a reason DisplayMemberBinding is overriding CellTemplate? If so, is there a fix for this (while still using DisplayMemberBinding)?
Edit: I ended up implementing it like this:
<Window xmlns:util="clr-namespace:TestProject.Util">
<Window.Resources>
<Style TargetType="ListViewItem">
<Setter Property="HorizontalContentAlignment" Value="Stretch"/>
</Style>
<Style TargetType="GridViewColumnHeader">
<Setter Property="HorizontalContentAlignment" Value="Left"/>
</Style>
<DataTemplate x:Key="value1Template">
<TextBlock TextAlignment="Right" Text="{Binding Path=value1}"/>
</DataTemplate>
<DataTemplate x:Key="value2Template">
<TextBlock TextAlignment="Right" Text="{Binding Path=value2}"/>
</DataTemplate>
</Window.Resources>
<Grid>
<ListView ItemsSource="{Binding MyData}" IsSynchronizedWithCurrentItem="True" util:GridViewSort.Command="{Binding SortCommand}">
<ListView.View>
<GridView>
<GridViewColumn Header="col1" CellTemplate="{StaticResource value1Template}" util:GridViewSort.PropertyName="value1"/>
<GridViewColumn Header="col2" CellTemplate="{StaticResource value2Template}" util:GridViewSort.PropertyName="value2"/>
</GridView>
</ListView.View>
</ListView>
</Grid>
</Window>
In the code behind:
private RelayCommand sortCommand;
public ICommand SortCommand { get { return sortCommand ?? (sortCommand = new RelayCommand(Sort)); } }
private void Sort(object param)
{
var propertyName = param as string;
var view = CollectionViewSource.GetDefaultView(MyData);
var direction = ListSortDirection.Ascending;
if (view.SortDescriptions.Count > 0)
{
var currentSort = view.SortDescriptions[0];
if (currentSort.PropertyName == propertyName)
direction = currentSort.Direction == ListSortDirection.Ascending ? ListSortDirection.Descending : ListSortDirection.Ascending;
view.SortDescriptions.Clear();
}
if (!string.IsNullOrEmpty(propertyName))
view.SortDescriptions.Add(new SortDescription(propertyName, direction));
}
DisplayMemberBinding has the highest priority. You can not use it combined with CellTemplate. See here in the remarks section.
If you want to right-or center-align the content, you must declare the CellTemplate with the binding (as you did) and remove the DisplayMemberBinding-attribute. If you also want to change the column header alignment, you must also set the GridViewColumn.Header-property.
Just add the following after your Window tag:
<Window.Resources>
<Style TargetType="ListViewItem">
<Setter Property="HorizontalContentAlignment" Value="Right" />
</Style>
</Window.Resources>
