# Creating a Full-Size Split

## Content

A full-size split is a horizontal or vertical split that stretches to fill the content area of a Windows Form. You can create a full-size split by setting one property: **C1SplitContainer.Dock** to Fill. In this topic, you'll learn how to set the **C1SplitContainer.Dock**property in design view and in code.

For more information on full-size splits, see [Full-Size Split](/componentone/docs/win/online-splitcontainer/splitcontainerlayout/splitcontainerlayout1/fullsizesplit1).

### In Design View:

Complete the following steps:

1. Add [C1SplitContainer](/componentone/docs/win/online-splitcontainer/) to the form.
2. Click on the C1SplitContainer’s smart tag to open its tasks menu.
3. Select **Add Panel** once to add one more [C1SplitterPanel](/componentone/docs/win/online-splitcontainer/) to the C1SplitContainer control.
4. Select C1SplitContainer1 from the Properties list dropdown box and set its **C1SplitContainer.Dock** property to **Fill**.
5. Run the program and observe that the control expands to the width and height of your Windows form.

### In Code View:

Complete the following steps:

1. Add the **C1.Win.C1SplitContainer.dll** reference to your project.
2. Declare the following **C1.Win.C1SplitContainer** namespace at the top of your code page:
<br>
    ```vbnet
    Imports C1.Win.C1SplitContainer
    ```

    ```csharp
    using C1.Win.C1SplitContainer;
    ```
3. Add the following code in the **Form\_Load** event:
<br>
    ```vbnet
    Private Sub Form1_Load(sender As Object, e As EventArgs)
       'create new splitcontainer
       Dim split As New C1SplitContainer()
        'create a new panel for the split container
       Dim panel1 As New C1SplitterPanel()
       Dim panel2 As New C1SplitterPanel()
         'add the panels to the splitcontainer
       split.Panels.Add(panel1)
       split.Panels.Add(panel2)
        panel1.Text = "Panel 1"
       panel2.Text = "Panel 2"
       split.Dock = DockStyle.Fill
       'add the splitcontainer
       Controls.Add(split)
    End Sub
    ```

    ```csharp
    private void Form1_Load(object sender, EventArgs e)
    {
       //create new splitcontainer
       C1SplitContainer split = new C1SplitContainer();
        //create a new panel for the split container
       C1SplitterPanel panel1 = new C1SplitterPanel();
       C1SplitterPanel panel2 = new C1SplitterPanel();
        //add panel1 to the splitcontainer
       split.Panels.Add(panel1);
       split.Panels.Add(panel2);
        panel1.Text = "Panel 1";
       panel2.Text = "Panel 2";
        //create a full size split
       split.Dock = DockStyle.Fill;
       //add the splitcontainer
       Controls.Add(split);
    }
    ```
4. Run the program and observe that the control expands to the width and height of your Window Form.
