In my xaml I am trying to display errors in Tooltip in a datagrid. The Texblock gets its border red and the grid row shows red "!" to say there is an error but tooptip is not displayed (on hovering the mouse)
xaml is
<Window.Resources>
<!--Error Template to change the default behaviour-->
<ControlTemplate x:Key="ErrorTemplate">
<DockPanel LastChildFill="True">
<Border BorderBrush="Red" BorderThickness="1">
<AdornedElementPlaceholder />
</Border>
</DockPanel>
</ControlTemplate>
<!--To display tooltip with the error-->
<Style TargetType="TextBlock">
<Style.Triggers>
<Trigger Property="Validation.HasError" Value="true">
<Setter Property="ToolTip"
Value="{Binding RelativeSource={x:Static RelativeSource.Self}, Path=(Validation.Errors)[0].ErrorContent}"/>
</Trigger>
</Style.Triggers>
</Style>
</Window.Resources>
<DataGrid Name="grid" HorizontalAlignment="Stretch" ItemsSource="{Binding mMngModelList}" Margin="0,0,0,50" VerticalAlignment="Stretch" AutoGenerateColumns="False" CanUserAddRows="False">
<DataGrid.Columns>
<DataGridTemplateColumn Header="Name">
<DataGridTemplateColumn.CellTemplate>
<DataTemplate>
<TextBlock Text="{Binding Name}" />
</DataTemplate>
</DataGridTemplateColumn.CellTemplate>

<DataGridTemplateColumn.CellEditingTemplate>
<DataTemplate>
<TextBox Text="{Binding Type}" />
</DataTemplate>
</DataGridTemplateColumn.CellEditingTemplate>
</DataGridTemplateColumn>
<DataGridTemplateColumn Header="Range Left">
<DataGridTemplateColumn.CellTemplate>
<DataTemplate>
<TextBlock Text="{Binding RangeLeft,ValidatesOnDataErrors=True, NotifyOnValidationError=True, ValidatesOnExceptions=True}" Validation.ErrorTemplate="{StaticResource ErrorTemplate}" />
</DataTemplate>
</DataGridTemplateColumn.CellTemplate>
<DataGridTemplateColumn.CellEditingTemplate>
<DataTemplate>
<TextBox Text="{Binding RangeLeft, ValidatesOnDataErrors=True, NotifyOnValidationError=True, ValidatesOnExceptions=True}" Validation.ErrorTemplate="{StaticResource ErrorTemplate}"/>
</DataTemplate>
</DataGridTemplateColumn.CellEditingTemplate>
</DataGridTemplateColumn>
</DataGrid.Columns>
</DataGrid>
In Code my class implements IDataErrorInfo and the code behind is
public string this[string columnName]
{
get
{
var result = string.Empty;
switch (columnName)
{
case "RangeLeft":
if (RangeLeft == 0)
{
result = "RangeLeft should be greater than zero";
}
break;
}
return result;
}
}
public string Error
{
get
{
StringBuilder error = new StringBuilder();
// iterate over all of the properties
// of this object - aggregating any validation errors
PropertyDescriptorCollection props = TypeDescriptor.GetProperties(this);
foreach (PropertyDescriptor prop in props)
{
String propertyError = this[prop.Name];
if (propertyError != string.Empty)
{
error.Append((error.Length != 0 ? ", " : "") + propertyError);
}
}
return error.Length == 0 ? null : error.ToString();
}
}
Also is there a way that until all validations are satisfied, the ObservableCollection is not updated?
Try this Style :
<Style TargetType="TextBox">
<Style.Triggers>
<Trigger Property="Validation.HasError" Value="true">
<Setter Property="ToolTip"
Value="{Binding RelativeSource={RelativeSource Self},
Path=(Validation.Errors)[0].ErrorContent}"/>
</Trigger>
</Style.Triggers>
</Style>

I would to like to enable a Button for a specific row of a DataGrid and disable it for the other rows in code behind. The thing is the IsEnabled property impact all the buttons in all the rows which is not what I want. It cannot have two different values (visible for some rows and Collapsed for others in the same time)
Can you help me please ?
here is my xaml :
<DataGrid ItemsSource="{Binding TaskUsers}" Name="DgUser" AutoGenerateColumns="False" IsReadOnly="True" SelectionUnit="FullRow" SelectionMode="Single" CanUserAddRows="False" CanUserSortColumns="False" SelectedValuePath="TaskUserId" >
<DataGrid.Columns>
<DataGridTemplateColumn>
<DataGridTemplateColumn.HeaderTemplate>
<DataTemplate>
<Button BorderThickness="0" ToolTip="Subscribe" Click="AddTaskUser_OnClick">
<Image Source="/Sinergi;component/Images/add-icon16.png"/>
</Button>
</DataTemplate>
</DataGridTemplateColumn.HeaderTemplate>
<DataGridTemplateColumn.CellTemplate>
<DataTemplate>
<Button BorderThickness="0" ToolTip="Delete a User" Click="DeleteTaskUser_OnClick" Name="DeleteUserButton" Loaded="DeleteUserButton_OnLoaded">
<Image Source="/Sinergi;component/Images/Trash-can-icon16.png" />
</Button>
</DataTemplate>
</DataGridTemplateColumn.CellTemplate>
</DataGridTemplateColumn>
<DataGridTextColumn Header="UserName" Binding="{Binding User.Name}" />
</DataGrid.Columns>
here is my code behind code
private void DeleteUserButton_OnLoaded(object sender, RoutedEventArgs e)
{
var delete = sender as Button;
if (delete == null) return;
foreach (var item in DgUser.Items)
{
var o = (TaskUser) item;
if (o.UserId == Identity.This.OnBehalfOfUser.UserId) continue;
delete.IsEnabled = false;
delete.Visibility = Visibility.Collapsed;
}
}
You should bind the IsEnabled property of the Button to a property of your TaskUser object and get rid of the DeleteUserButton_OnLoaded event handler:
<DataTemplate>
<Button BorderThickness="0" ToolTip="Delete a User" Click="DeleteTaskUser_OnClick" Name="DeleteUserButton">
<Button.Style>
<Style TargetType="Button" BasedOn="{StaticResource {x:Type Button}}">
<Style.Triggers>
<DataTrigger Binding="{Binding UserId}" Value="{x:Static local:Identity.This.OnBehalfOfUser.UserId}">
<Setter Property="IsEnabled" Value="False" />
</DataTrigger>
</Style.Triggers>
</Style>
</Button.Style>
<Button.Content>
<Image Source="/Sinergi;component/Images/Trash-can-icon16.png" />
</Button.Content>
</Button>
</DataTemplate>
You need to set the Value of the DataTrigger to whatever Identity.This.OnBehalfOfUser.UserId is, or use a value converter:
<DataTemplate>
<DataTemplate.Resources>
<local:Converter x:Key="converter" />
</DataTemplate.Resources>
<Button BorderThickness="0" ToolTip="Delete a User" Click="DeleteTaskUser_OnClick" Name="DeleteUserButton">
<Button.Style>
<Style TargetType="Button" BasedOn="{StaticResource {x:Type Button}}">
<Style.Triggers>
<DataTrigger Binding="{Binding UserId, Converter={StaticResource converter}}" Value="False">
<Setter Property="IsEnabled" Value="False" />
</DataTrigger>
</Style.Triggers>
</Style>
</Button.Style>
<Button.Content>
<Image Source="/Sinergi;component/Images/Trash-can-icon16.png" />
</Button.Content>
</Button>
</DataTemplate>
Converter:
class Converter : IValueConverter
{
public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
{
return (int)value == Identity.This.OnBehalfOfUser.UserId;
}
public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
{
throw new NotSupportedException();
}
}
I have TreeView in my WPF window. The TreeViews DataContext is bound to a XDocument.
I am in search for setting the selectedItem from code behind. As the nodes returned by for example .ItemContainerGenerator.Items are of type System.Xml.Linq.XElement and not System.Windows.Controls.TreeViewItem I can not just set isSelected :-(
Does anybody have an idea how to solve this?

After sleeping a weekend about this I found an answer myself. There were some more problems as only the return type.
The solution is, to get the matching ItemContainer for the Item. This Container is of type TreeViewItem, where I can set isSelected an the like.
As an example is most of the time better for understanding, I give one. The following function will search for a XML- node in a TreeView- object and return a TreeViewItem, that contains the matching Node. If no Match is found null is returned.
The matching node is expanded.
The XML is handled in a System.Xml.linq.XDocument which is bound to the System.Windows.Controls.TreeView DataContext.
When calling the function The TreeView is set as ic.
public static TreeViewItem SearchNodeInTreeView(ItemsControl ic, XElement NodeDescription, string indent = "")
{
TreeViewItem ret = null;
foreach (object o in ic.Items)
{
if (o is XElement)
{
var x = ic.ItemContainerGenerator.ContainerFromItem(o);
if (XNode.DeepEquals((o as XElement), NodeDescription))
{
ret = x as TreeViewItem;
}
else if ((o as XElement).HasElements){
if (x != null)
{
bool expanded = (x as TreeViewItem).IsExpanded;
(x as TreeViewItem).IsExpanded = true;
(x as TreeViewItem).UpdateLayout();
ret = SearchNodeInTreeView (x as TreeViewItem, NodeDescription, indent + " ");
if (ret == null)
{
(x as TreeViewItem).IsExpanded = expanded;
(x as TreeViewItem).UpdateLayout();
}
}
}
}
if (ret != null)
{
break;
}
}
return ret;
}
I hope I can help anybody with this.
I am working in Visual Studio 2013 in WPF (C#) and I have the following code to create an expander from my xml. It is currently working perfectly right now but I want to include an expand all and collapse all buttons. I have looked all over and can't seem to find a solution.
Here is where the expander is created. I know I just have to iterate through a list of items and change the Property="IsExpanded" to Value="True" to create an expand all.
<DataTemplate x:Key="dtListTemplate" >
<StackPanel>
<Expander LostFocus="CollapseExpander" ExpandDirection="Down" Width="Auto">
<Expander.Style>
<Style TargetType="Expander">
<Setter Property="IsExpanded" Value="False" />
<Setter Property="Header" Value="{Binding XPath=#Name}" />
<Setter Property="FontWeight" Value="Bold"/>
<Style.Triggers>
<DataTrigger Binding="{Binding IsExpanded,RelativeSource={RelativeSource Self}}" Value="True">
</DataTrigger>
</Style.Triggers>
</Style>
</Expander.Style>
<ListBox Name="itemsList"
ItemsSource="{Binding XPath=UpgradeAction}"
ItemTemplate="{StaticResource dtListItemTemplate}"
SelectionChanged="listItems_SelectionChanged"
Style="{StaticResource styleListBoxUpgradeAction}"
ItemContainerStyle="{StaticResource styleListBoxItemUpgradeAction}">
</ListBox>
</Expander>
</StackPanel>
</DataTemplate>
Here's the code that calls the DataTemplate which has information from an Xml.
<StackPanel>
<StackPanel Orientation="Horizontal" HorizontalAlignment="Right">
<Border Grid.Column="0" Grid.Row="0" Width="790" Height="40" Padding="5" Background="#4E87D4">
<Label VerticalAlignment="Center" FontSize="16" FontWeight="Bold" Foreground="White">Test</Label>
</Border>
<Button Name="ExpandBttn" Width="100" Height="40" FontSize="16" FontWeight="Bold" Content="Expand All" DataContext="{Binding}" Click="Expand_Button_Click"/>
<Button Name="ColapseBttn" Width="100" Height="40" FontSize="16" FontWeight="Bold" Content="Colapse All" DataContext="{Binding}" Click="Collapse_Button_Click"/>
</StackPanel>
<ListView Name="listItems" Grid.Column="0" Grid.Row="1" Background="Wheat"
ItemsSource="{Binding Source={StaticResource xmldpUpgradeActions}, XPath=ActionGroup}"
ItemTemplate="{StaticResource dtListTemplateRichards}"
SelectionChanged="listItems_SelectionChanged">
</ListView>
</StackPanel>
Here's what I tried in the .cs file for the expand all portion.
private void Expand_Button_Click(object sender, RoutedEventArgs e)
{
foreach(var item in listItems.Items)
{
var listBoxItem = listItems.ItemContainerGenerator.ContainerFromItem(item) as ListBoxItem;
var itemExpander = (Expander)GetExpander(listBoxItem);
if (itemExpander != null)
itemExpander.IsExpanded = true;
}
}
private static DependencyObject GetExpander(DependencyObject container)
{
if (container is Expander) return container;
for (var i = 0; i < VisualTreeHelper.GetChildrenCount(container); i++)
{
var child = VisualTreeHelper.GetChild(container, i);
var result = GetExpander(child);
if (result != null)
{
return result;
}
}
return null;
}
Any help is greatly appreciated!
Is xmldpUpgradeActions a CollectionViewSource?
Whatever class is in the collection, it should implement INotifyPropertyChanged.
Give it an IsExpanded property that raises PropertyChanged in its setter when its value changes, and bind that to Expander.IsExpanded in the template:
<Expander
IsExpanded="{Binding IsExpanded}"
LostFocus="CollapseExpander"
ExpandDirection="Down"
Width="Auto">
Write a command that loops through all the items in the collection and sets item.IsExpanded = false; on each one.
I want make a footer to my DataGrid using this method:
How do I add a footer row in a WPF datagrid?
But, i need to make this by code behind, and that's don't working.
I think it's because the binding of the grid can't find the column.
private DataGridColumn dgInsertCol(ref int idx, DataGridColumn dgc, tblEtatRecapColonne pCol, string pBinding = "") {
var dhHeadName = $"dgHead{pCol.Id}";
dgc.SetValue(NameProperty, dhHeadName);
dgc.HeaderTemplate = GetDtHeader(pCol, pBinding);
dgc.Width = new DataGridLength(1.0, (ckbSize.IsChecked.Value) ? DataGridLengthUnitType.Star : DataGridLengthUnitType.SizeToCells);
dgMain.Columns.Insert(idx++, dgc);
// Faire le footer associé
var t = new TextBlock() { Margin = new Thickness(5, 0, 0, 0), Text = pBinding, Background = new SolidColorBrush(Color.FromRgb(50, 100, 150)) };
var g = new Grid() { MinWidth = 10 };
g.SetBinding(Grid.WidthProperty, new Binding("ActualWidth") { ElementName = dhHeadName, Path=new PropertyPath("ActualWidth", null) }); // DataGridColumn
g.Children.Add(t);
pnlDgFooter.Children.Add(g);
return dgc;
}

Why use ElementName at all? Set the Source of the Binding directly. Also, don't set Path twice, so either write
g.SetBinding(Grid.WidthProperty,
new Binding
{
Source = dgc,
Path = new PropertyPath("ActualWidth")
});
or
g.SetBinding(Grid.WidthProperty, new Binding("ActualWidth") { Source = dgc });
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.
