I'm wanting to have a CheckBox as the Header in a GroupBox but all I'm getting in the Header is: System.Windows.Controls.CheckBox Content:My CheckBoxHeader IsChecked:False
<GroupBox>
<GroupBox.Header>
<CheckBox Content="My CheckBoxHeader" />
</GroupBox.Header>
</GroupBox>
Any ideas?
Edit:
This is in a simple UserControl.

As the title say, I need to know how can I set a specific header height for a GroupBox, suppose I've this:
<GroupBox Header="Test">
</GroupBox>
this will display an header height based on the content of the header, but is possible also set a specific header height? How?
Thanks.
Instead of using a string for setting the GroupBox Header property, use directly a TextBlock, something like that:
<GroupBox>
<GroupBox.Header>
<TextBlock Text="High Header" VerticalAlignment="Bottom" MinHeight="100" />
</GroupBox.Header>
<Button Content="Button1" />
</GroupBox>
I have tried the following below but it always ends up setting the cursor for all of the elements instead of just the TabControl header text.
<TabControl Cursor="Hand"></TabControl>
<TabItem Cursor="Hand"></TabItem>
Thinking I might have to override some template of some sort?
Thanks in advance.
Try defining the structure of the header and assigning the cursor pointer to that:
<TabItem>
<TabItem.Header>
<TextBlock Text="Header goes here..." Cursor="Hand" />
</TabItem.Header>
<Label Content="Content goes here..." />
</TabItem>
i want groupbox's header editable that means at runtime i want it to be open for edit like we do rename in microsoft excelsheet in bottom left.
i came to know we can do it by control template but don't know how to write template for it.
It's easy to create Editable Header:
<GroupBox>
<GroupBox.HeaderTemplate>
<DataTemplate>
<TextBox Text="Editable Header"/>
</DataTemplate>
</GroupBox.HeaderTemplate>
<TextBlock Text="Some Content" VerticalAlignment="Center" HorizontalAlignment="Center"/>
</GroupBox>
Or if you want to modify the template of all control?
Then you can find sample here: https://msdn.microsoft.com/en-us/library/vstudio/ms744748(v=vs.100).aspx
I've got a rather strange behavior on a TabControl, whose TabItems are all collapsed: The content of the first TabItem is still visible (but the header is not).
The TabControl and its TabItems are setup like this:
<TabControl>
<TabItem Header="Data 1"
Visibility="{Binding Path=DataTable1.HasRows,
Converter={StaticResource BoolToVisibility}}">
<UI:ShowData DataContext="{Binding Path=DataTable1}"/>
</TabItem>
<TabItem Header="Data 2"
Visibility="{Binding Path=DataTable2.HasRows,
Converter={StaticResource BoolToVisibility}}">
<UI:ShowData DataContext="{Binding Path=DataTable2}"/>
</TabItem>
</TabControl>
If none of the data tables contains any rows, none of the TabItems should be shown. (I known that I could hide the whole TabControl in that case, but that's not the point here.)
Actually the content of the tab item "Header 1" will be displayed despite the TabItem being collapsed! The TabItem's header itself is collapsed, the TabItems border which contains its content and the content itself are displayed.
Edit/Add:
This can easily be reproduced using this code (note using Collapsed or Hidden does not make any difference:
<TabControl>
<TabItem Header="Test 1" Visibility="Hidden">
<Label>Test1</Label>
</TabItem>
<TabItem Header="Test 2" Visibility="Hidden">
<Label>Test2</Label>
</TabItem>
</TabControl>
So what's wrong here? Any help/hints are appreciated!
Ok, so you've found a real problem here... I looked around online and found several posts that relate to this. Some say that this is a bug, while others say that it is the designed behaviour. don't know which, although it certainly seems to be more of a bug than a feature.
Either way, you want to know how to deal with the problem. .. there are several solutions. One is just to set the TabItem.Content to null whenever you want to hide the tab and another is another involves adding an empty TabItem and selecting that item before hiding (so that it's empty content is shown).
You can attach a handler to the TabItem.IsVisibleChanged Event to be notified when the Visibility property has been changed:
public void TabItemIsVisibleChanged(object sender, DependencyPropertyChangedEventArgs e)
{
// Hide TabItem.Content here
}
Here are some links to the relevant posts:
Bug in TabControl/TabItem`s content visibility?
WPF TabControl - Select different tab when TabItem Visibility changes
Is there a workaround for this tabcontrol/tabitem bug
Another solution that I prefer over the ones suggested: Bind the visibility of the TabItem and its content to the same property (using the BooleanToVisibilityConverter).
Here's a simple example:
<UserControl.Resources >
<BooleanToVisibilityConverter x:Key="boolToVis"/>
</UserControl.Resources>
<Grid>
<TabControl>
<TabItem Header="TabItem 1" Visibility="{Binding Item1Visibility, Converter={StaticResource boolToVis}}">
<Label Content="Content 1" Visibility="{Binding Item1Visibility, Converter={StaticResource boolToVis}}"/>
</TabItem>
<TabItem Header="TabItem 2" Visibility="{Binding Item1Visibility, Converter={StaticResource boolToVis}}">
<Label Content="Content 2" Visibility="{Binding Item1Visibility, Converter={StaticResource boolToVis}}"/>
</TabItem>
</TabControl>
</Grid>
Could be a WPF bug, anyway bypass by binding the content visibility to the tab item visibility.
<TabControl>
<TabItem x:Name="_test1Tab" Header="Test 1" Visibility="Hidden">
<Label Visibility="{Binding ElementName=_test1Tab, Path=Visibility}">Test1</Label>
</TabItem>
<TabItem x:Name="_test2Tab" Header="Test 2" Visibility="Hidden">
<Label Visibility="{Binding ElementName=_test1Tab, Path=Visibility}">Test2</Label>
</TabItem>
</TabControl>
My solution to this was to put the TabItem I wanted to hide in another position. The problem happens only if you want to collapse only the first TabItem.
Tooltips on a TabControl's TabItems are not only spawn on the TabItem's header, but also on any TabItem content which doesn't explicitly set its own ToolTip.
Here is an example, which reproduces the problem:
<Window x:Class="TestToolTipsOnTabControl.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow">
<Grid>
<TabControl>
<TabItem Header="Tab1"
ToolTip="Tooltip of tab1">
<StackPanel>
<TextBlock Text="Content of tab1 with its own tooltip"
ToolTip="Tooltip on content of tab1"/>
<TextBlock Text="more content of tab1" />
</StackPanel>
</TabItem>
<TabItem Header="Tab2"
ToolTipService.ToolTip="Tooltip of tab2">
<StackPanel>
<TextBlock Text="Content of tab2 with its own tooltip"
ToolTipService.ToolTip="Tooltip on content of tab2"/>
<TextBlock Text="more content of tab2" />
</StackPanel>
</TabItem>
<TabItem Header="Tab3">
<StackPanel>
<TextBlock Text="Content of tab3" />
<TextBlock Text="more content of tab3" />
</StackPanel>
</TabItem>
</TabControl>
</Grid>
</Window>
Moving the mouse pointer over the "more content of tab1" text will display the ToolTip which I'd like to only show up on the TabItem header.
Is there any way to for the ToolTip to show up only on the TabItem header, but nowhere else?

You should only apply Tooltip to the Header not the whole TabItem so change it to:
<TabItem>
<TabItem.Header>
<TextBlock Text="Tab1"
ToolTip="Tooltip of tab1"/>
</TabItem.Header>
<StackPanel>
<TextBlock Text="Content of tab1 with its own tooltip"
ToolTip="Tooltip on content of tab1"/>
<TextBlock Text="more content of tab1" />
</StackPanel>
</TabItem>
Add the below piece of code to the textblocks
ToolTip="", ToolTipSevice.ShowDuration="0"
This works for me when adding tabItems dynamically:
TabItem nt = new TabItem
string _newTabItemText = "xxxx" // Dynamic header text
string _newTabItemTooltip = "xxxx Tooltip" // Dynamic tooltip text
string _newTabItemName = "xxxx" // tabItem name to reference the tab item in code ie XAML x:name = "xxxx"
{
Header = new TextBlock() { Text = _newTabItemText, ToolTip = _newTabItemTooltip },
Name = _newTabItemName,
Width = 108
};
As an alternative, I can offer is this: created a Style for ToolTip with zero Width and Height:
<Style x:Key="NullToolTip" TargetType="{x:Type ToolTip}">
<Setter Property="Width" Value="0" />
<Setter Property="Height" Value="0" />
<Setter Property="Content" Value="{x:Null}" />
</Style>
When created ToolTip with this Style and placed in Resources:
<ToolTip x:Key="NoToolTip" Style="{StaticResource NullToolTip}" />
And assign to control that want to turn off the ToolTip:
<TabItem Header="Tab1" ToolTip="Tooltip of tab1">
<StackPanel>
<TextBlock Text="Content of tab1 with its own tooltip" ToolTip="Tooltip on content of tab1"/>
<TextBlock Text="more content of tab1" ToolTipService.ToolTip="{StaticResource NoToolTip}" />
</StackPanel>
</TabItem>
Note: Similar problem appears when you use the ToolTip for TreeViewItem. His children inherit parent ToolTip.
Just in case someone is running into this issue when creating the tabs dynamically, the following code did the magic:
TabItem tabItem = new TabItem();
var stackPanel = new StackPanel();
var stackPanelToolTip = new System.Windows.Controls.ToolTip();
stackPanelToolTip.Content = "ToolTip content";
stackPanel.ToolTip = (stackPanelToolTip);
tabItem.Header = stackPanel;
So the key here was to add the tooltip to the tab header, but not to the tab element (adding it to the header means that you will have the tooltip visible only when mouse is hover the tab).
