I have a WPF Tab Control..
i am adding tabs in that TabControl dynamically
Now i want to give a Close Button in every Tab of Tab Control..
So please tell me hopw to add Close button in that Tab Control..
Code for adding tab
private void AddTab(ITabbedMDI mdiChild)
{
if (_mdiChildren.ContainsKey(mdiChild.UniqueTabName))
{
//user control is already opened in tab.
//So set focus to the tab item where the control hosted
foreach (object item in tcMdi.Items)
{
TabItem ti = (TabItem)item;
if (ti.Name == mdiChild.UniqueTabName)
{
ucChildLoc = (UserControl)mdiChild;
ti.Focus();
//tcMdi.Width = this.ucChildLoc.Width;
//tcMdi.Height = this.ucChildLoc.Height;
break;
}
}
}
}
Code for Closing tab
private void CloseTab(ITabbedMDI tab, EventArgs e)
{
TabItem ti = null;
foreach(TabItem item in tcMdi.Items)
{
if (tab.UniqueTabName == ((ITabbedMDI)item.Content).UniqueTabName)
{
ti = item;
break;
}
}
if (ti != null)
{
_mdiChildren.Remove(((ITabbedMDI)ti.Content).UniqueTabName);
tcMdi.Items.Remove(ti);
}
}

Thanks in Advance..
I have tried several solutions and struggled to find something that looked nice and also highlighted the "X" in the button when the mouse hovers. I finally ended with this one. It also does not require too much code. I hope it helps:
<TabControl>
<TabItem>
<TabItem.Header>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
<ColumnDefinition Width="Auto" />
</Grid.ColumnDefinitions>
<TextBlock Grid.Column="0">Output</TextBlock>
<Button Grid.Column="1" Name="button_close" Click="button_close_Click">
<Button.Template>
<ControlTemplate TargetType="Button">
<Path Data="M0,0 L8,8 M8,0 L0,8" StrokeThickness="3" VerticalAlignment="Center" Margin="5,4,0,2">
<Path.Style>
<Style TargetType="{x:Type Path}">
<Style.Triggers>
<Trigger Property="IsMouseOver" Value="False">
<Setter Property="Stroke" Value="LightGray" />
</Trigger>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="Stroke" Value="Black" />
</Trigger>
</Style.Triggers>
</Style>
</Path.Style>
</Path>
</ControlTemplate>
</Button.Template>
</Button>
</Grid>
</TabItem.Header>
<TabItem.Content>
</TabItem.Content>
if you make the tab control as a custom control and inherit the functionality from tab control and then add close button and handle its events then it can work
<UserControl x:Class="CloseableHeader"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
mc:Ignorable="d"
d:DesignHeight="23" d:DesignWidth="81" Margin="0">
<Grid>
<Button Content="X" Height="19" HorizontalAlignment="Right" Margin="0,3,4,0"
Name="button_close" VerticalAlignment="Top" Width="20" FontFamily="Courier"
FontWeight="Bold" Style="{StaticResource {x:Static ToolBar.ButtonStyleKey}}"
FontStretch="Normal" Visibility="Visible"
FontSize="14" Padding="0" ToolTip="Close"/>
<Label Content="TabItem" Height="23" HorizontalAlignment="Left"
Margin="4,1,0,0" Name="label_TabTitle" VerticalAlignment="Top"
FontFamily="Courier" FontSize="12" />
</Grid>
class ClosableTab : TabItem
{
// Constructor
public ClosableTab()
{
// Create an instance of the usercontrol
closableTabHeader = new CloseableHeader();
// Assign the usercontrol to the tab header
this.Header = closableTabHeader;
}
}
