# Step 4 of 4: Sizing the C1SplitContainer Control

## Content



In this step, you will create a fixed size and absolute size panel and run the project to see the effect of the panels sizing.

Complete the following steps:

1.  Select c1SplitterPanel1 of C1SplitContainer1 and set its following properties:
    *   Set the **c1SplitterPanel1.Width** property to **80**.
    *   Set the **c1SplitterPanel1.KeepRelativeSize** property to **False**.
    *   Set the **c1SplitterPanel1.Resizable** property to **False**.
    *   Set the **c1SplitterPanel1.Text** property to **Fixed**.
2.  Select c1SplitterPanel4 of the C1SplitContainer1 and set its the **c1SplitterPanel4.MinWidth** property to **80**.
3.  Press **F5** to build the project. Observe the following behaviors:
    
    *   Hover over the expander button and notice that a tooltip appears with the default text, “minimize panel 1”.
    *   Click the expander button and notice panel1 collapses.
    *   Notice how you can’t resize the Fixed panel since you set the [Resizable](/componentone/docs/win/online-splitcontainer/) property to **False**.
    *   Click the splitter bar to activate it and then attempt to drag the splitter bar to the bottom of the control.

    As you've probably noticed by now – and as you can see in the image above – you can't expand the bar all the way over to the right of the control. This is because you set the [MinWidth](/componentone/docs/win/online-splitcontainer/) to **80** so that users wouldn't be able to minimize **Panel 3** to a width of less than 80 pixels. Thus, upon releasing your cursor, Panel 3 will appear no smaller than 80 pixels.
    

### What You've Accomplished

Congratulations! You have successfully completed the [C1SplitContainer](/componentone/docs/win/online-splitcontainer/) quick start. In this topic, you added a C1SplitContainer control to your window page, added panels, customized its behavior and appearance, and manipulated the control at run time.
