C# – How to add user control in tab control in WPF

ctabitemwpf

The below article shows how to create dynamic tabs in WPF, that in each tab it will add just one text box.

private TabItem AddTabItem()
{
    int count = _tabItems.Count;

    // create new tab item
    TabItem tab = new TabItem();

    tab.Header = string.Format("Tab {0}", count);
    tab.Name = string.Format("tab{0}", count);
    tab.HeaderTemplate = tabDynamic.FindResource("TabHeader") as DataTemplate;

    tab.MouseDoubleClick += new MouseButtonEventHandler(tab_MouseDoubleClick);

    // add controls to tab item, this case I added just a textbox
    TextBox txt = new TextBox();

    txt.Name = "txt";
    tab.Content = txt;
    // insert tab item right before the last (+) tab item
    _tabItems.Insert(count - 1, tab);

    return tab;
}

what can I do for adding some complex controls that their positions are fixed instead of just 1 text box? can I create a user control for this purpose? so how can I add the user control to tab control?

Try the next steps:

  1. Add a user control (Lets say in ComplexControl.xaml)

    <UserControl ... >
   <Grid>
       <Rectangle Width="100" Height="100" Fill="Red"/>
    </Grid>
 </UserControl>

  2. Create a class

    Public myComplexContolClass
{
     //....
}

  3. Map them together so when you have a myComplexContolClass in your app visually it will be the UserControl from 1. The map can be done with DataTemplate:

    <ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
                    ...
                    xmlns:models="clr-namespace: ... .Model"
                    xmlns:views="clr-namespace: ... .View"
                    >

    <DataTemplate DataType="{x:Type models:myComplexContolClass}">
        <views:ComplexControl/>
    </DataTemplate>

</ResourceDictionary>

Or

    <Window ...
            xmlns:models="clr-namespace: ... .Model"
            xmlns:views="clr-namespace: ... .View"
            >

        <Window.Resources>

            <DataTemplate DataType="{x:Type models:myComplexContolClass}">
                <views:ComplexControl/>
            </DataTemplate>

        </Window.Resources>

        // ...

    </Window>

  1. Add it to your code:

    private TabItem AddTabItem()
{
    // ...

    myComplexContolClass control = new myComplexContolClass();
    tab.Content = control;

    // ...
}
