C1SplitContainer has a WYSIWYG editor that allows you to view the end result without having to run the project. With the WYSIWYG designer interface C1SplitContainer supports, it makes it simple to arrange child controls in the containers of the panels because C1SplitContainer displays them as it would at run time. You can add as many child controls to each panel by dragging and dropping each control into the desired panel.

Panels can be selected on the Form by clicking anywhere inside the rectangular box.

The WYSIWYG designer interface makes it simple to add child controls to a specific splitter panel via drag and drop. You also can add child controls programmatically to a specific splitter panel through the C1SplitterPanel object since it is a control.

To add a C1SplitterPanel programmatically to a specified panel, use the following code:

Visual Basic

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 panel1 to the splitcontainer
       split.Panels.Add(panel1)
       split.Panels.Add(panel2)
       Controls.Add(split)
End Sub

To write code in C#

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);
             Controls.Add(split);
        }
