By default, the color of the C1SplitContainer border is determined by its visual style; however, you can change the color of that border using the BorderColor property. In this topic, you will learn how to set the BorderColor property in design view and in code.

In Design View:

Complete the following steps:

1. Add the C1SplitContainer to the form.
2. In the C1SplitContainer Properties window set the BorderColor property to “Black”.
   The border color is updated on the C1SplitContainer control.

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:

   Visual Basic

   Visual Basic	Copy Code
   Imports C1.Win.C1SplitContainer

   To write code in C#

   C#	Copy Code
   using C1.Win.C1SplitContainer;

3. Add the following code in the Form_Load event:

   Visual Basic

   Visual Basic	Copy Code
   Private Sub Form1_Load(sender As Object, e As EventArgs) 'create new splitcontainer Dim split As New C1SplitContainer() 'set splitcontainer border color to black split.BorderColor = Color.Black 'add the splitcontainer Controls.Add(split) End Sub

   To write code in C#

   C#	Copy Code
   private void Form1_Load(object sender, EventArgs e) { //create new splitcontainer C1SplitContainer split = new C1SplitContainer(); //set splitcontainer border color to black split.BorderColor = Color.Black; //add the splitcontainer Controls.Add(split); }

4. Run the program.

The image below shows the C1SplitContainer with a black border.
