How do I show tooltips for the listview items?

You can do so by first defining a DataTemplate for the corresponding columns as follows. Sample code can be seen with better formatting in this thread (ListView Column ToolTip) [XAML] <Page xmlns=\'http://schemas.microsoft.com/winfx/2006/xaml/presentation\' xmlns:x=\'http://schemas.microsoft.com/winfx/2006/xaml\'> <StackPanel> <StackPanel.Resources> <DataTemplate x:Key=\'nameTemplate\'> <TextBlock Text=\'{Binding Name}\' Margin=\'-6,0\'> <TextBlock.ToolTip> <ToolTip> <TextBlock Foreground=\'Green\' Text=\'{Binding Name}\'/> </ToolTip> </TextBlock.ToolTip> </TextBlock> </DataTemplate> <DataTemplate x:Key=\'namespaceTemplate\'> <TextBlock Text=\'{Binding Namespace}\' Margin=\'-6,0\'> <TextBlock.ToolTip> <ToolTip> <TextBlock Foreground=\'Green\' Text=\'{Binding Namespace}\'/> </ToolTip> </TextBlock.ToolTip> </TextBlock> </DataTemplate> </StackPanel.Resources> <ListView> <ListView.ItemContainerStyle> <Style TargetType=\'ListViewItem\'> <Setter Property=\'HorizontalContentAlignment\' Value=\'Stretch\'/> <Setter Property=\'VerticalContentAlignment\' Value=\'Stretch\'/> </Style> </ListView.ItemContainerStyle> <ListView.View> <GridView> <GridViewColumn CellTemplate=\'{StaticResource nameTemplate}\' Width=\'300\' Header=\'Name\'/> <GridViewColumn CellTemplate=\'{StaticResource namespaceTemplate}\' Width=\'300\' Header=\'Namespace\'/> </GridView> </ListView.View> <x:Type TypeName=\'Visual\'/> <x:Type TypeName=\'FrameworkElement\'/> <x:Type TypeName=\'FrameworkContentElement\'/> </ListView> </StackPanel> </Page>

How do I move the focus to a ListViewItem that could also be out of view?

You can do so as follows: [C#] this.myList.SelectedItem = o; // In case the item is out of view. If so, the next line could cause an exception without bringing this item to view. myList.ScrollIntoView(this.myList.SelectedItem); ListViewItem lvi = (ListViewItem)myList.ItemContainerGenerator.ContainerFromIndex(myList.SelectedIndex); lvi.Focus();

How do I access the ui element at a row/cell in my GridView?

The following utility class (provided in this thread: Accessing and Mondifying DataTemplate Element Runtime for CellTemplate should help you achieve this: [C#] public static class ListViewHelper { public static FrameworkElement GetElementFromCellTemplate(ListView listView, Int32 column, Int32 row, String name) { if (row >= listView.Items.Count || row < 0) { throw new ArgumentOutOfRangeException(\'row\'); } GridView gridView = listView.View as GridView; if (gridView == null) { return null; } if (column >= gridView.Columns.Count || column < 0) { throw new ArgumentOutOfRangeException(\'column\'); } ListViewItem item = listView.ItemContainerGenerator.ContainerFromItem(listView.Items[row]) as ListViewItem; if (item != null) { GridViewRowPresenter rowPresenter = GetFrameworkElementByName(item); if (rowPresenter != null) { ContentPresenter templatedParent = VisualTreeHelper.GetChild(rowPresenter, column) as ContentPresenter; DataTemplate dataTemplate = gridView.Columns[column].CellTemplate; if (dataTemplate != null && templatedParent != null) { return dataTemplate.FindName(name, templatedParent) as FrameworkElement; } } } return null; } private static T GetFrameworkElementByName(FrameworkElement referenceElement) where T : FrameworkElement { FrameworkElement child = null; for (Int32 i = 0; i < VisualTreeHelper.GetChildrenCount(referenceElement); i++) { child = VisualTreeHelper.GetChild(referenceElement, i) as FrameworkElement; System.Diagnostics.Debug.WriteLine(child); if (child != null && child.GetType() == typeof(T)) { break; } else if (child != null) { child = GetFrameworkElementByName(child); if (child != null && child.GetType() == typeof(T)) { break; } } } return child as T; } }

How do I create a single template and resue it for multiple columns in a ListView?

Here is a solution: [XAML] <Page xmlns=\'http://schemas.microsoft.com/winfx/2006/xaml/presentation\' xmlns:x=\'http://schemas.microsoft.com/winfx/2006/xaml\' xmlns:sys=\'clr-namespace:System;assembly=mscorlib\'> <Page.Resources> <XmlDataProvider x:Key=\'CharacterData\'> <x:XData> <Data xmlns=\'\'> <Character First=\'Bart\' Last=\'Simpson\' Gender=\'M\'/> <Character First=\'Homer\' Last=\'Simpson\' Gender=\'M\'/> <Character First=\'Lisa\' Last=\'Simpson\' Gender=\'F\'/> <Character First=\'Maggie\' Last=\'Simpson\' Gender=\'F\'/> <Character First=\'Marge\' Last=\'Simpson\' Gender=\'F\'/> </Data> </x:XData> </XmlDataProvider> <DataTemplate x:Key=\'LVTSimpleText\'> <Border Width=\'Auto\' Height=\'Auto\' BorderBrush=\'#FF000000\' BorderThickness=\'0,0,2,2\'> <TextBox Width=\'Auto\' Height=\'Auto\' Text=\'{Binding Value}\' TextWrapping=\'Wrap\'/> </Border> </DataTemplate> </Page.Resources> <ListView ItemsSource=\'{Binding Source={StaticResource CharacterData}, XPath=Data/Character}\'> <ListView.View> <GridView> <GridViewColumn Header=\'First Name\'> <GridViewColumn.CellTemplate> <DataTemplate> <ContentControl Content=\'{Binding XPath=@First}\' ContentTemplate=\'{StaticResource LVTSimpleText}\' /> </DataTemplate> </GridViewColumn.CellTemplate> </GridViewColumn> <GridViewColumn Header=\'Last Name\'> <GridViewColumn.CellTemplate> <DataTemplate> <ContentControl Content=\'{Binding XPath=@Last}\' ContentTemplate=\'{StaticResource LVTSimpleText}\' /> </DataTemplate> </GridViewColumn.CellTemplate> </GridViewColumn> <GridViewColumn Header=\'Gender\'> <GridViewColumn.CellTemplate> <DataTemplate> <ContentControl Content=\'{Binding XPath=@Gender}\' ContentTemplate=\'{StaticResource LVTSimpleText}\' /> </DataTemplate> </GridViewColumn.CellTemplate> </GridViewColumn> </GridView> </ListView.View> </ListView> </Page>

How do I color the bg of my ListView in GridView mode based on a ‘search’ textbox where the user can enter search text?

This is kind of how Firefox lets you search texts – as you type in the search box the matching text all get highligted automatically. You can use this solution for other templatized controls as well. (For better formatting, take a look at this thread: How to color particular cell of the grid view?)
