You would expect them to maintain the same distance from the right and bottom edges of the form. If you resize the form at runtime, you will find that the buttons assume a fixed location. AnchoringĪssume that you are developing a resizable dialog box that has two buttons, OK and Cancel (see below). This time, as the form is resized, the Label is also resized and always remains attached to the bottom of the form. To see this property in action, set the Dock property of the Label control to Bottom and run the form again. You can also make the control fill the available area of the form.

Windows Forms controls have a property called Dock that can dock that control to left, right, top, or bottom edge of the form. This is where the docking feature comes into picture. The expected behavior would be that the Label always remains attached with the bottom edge on the form. This is certainly undesirable (see below). You will find that, as the form is resized, the Label doesn’t change its position and size. The form has a Label control at the bottom that displays some status message to the user. Suppose that you want to develop a form as shown below: This can be easily corrected by setting Form’s AutoSize property to true. As a result, buttons expand beyond the form boundaries. You will find that the buttons adjust themselves as per the text but the form remains the same. Now, enter a very long string and check the behavior. It expands as well as shrinks according to the length of the text value. Notice the behavior of the second button. This time, you will observe that the buttons adjust their width as per the text entered. The value of GrowAndShrink indicates that the control can expand or shrink to fit its content.
The value of GrowOnly indicates that the control can only expand to accommodate its content. The AutoSizeMode property governs how a control should behave to adjust its contents. Also, set the AutoSizeMode property of the first button to GrowOnly and that of the second button to GrowAndShrink. The AutoSize property governs whether a control should automatically adjust its width to accommodate its contents. Now, set the AutoSize property of both buttons to true. The following figure shows a sample run of the form.Ĭan you see the problem? The button controls do not display the complete text. Enter some big string value in the textbox and click the “Change Text” button.

The code simply sets the Text property of button1 and button2 to a string entered in textBox1. Private void button3_Click(object sender, EventArgs e) Write the following code in the Click event handler of “Change Text” button. Clicking on the “Change Text” button changes Text property of the remaining two buttons to a value entered in the textbox. The form consists of a textbox and three buttons. Before going any further, let me illustrate why such auto sizing is necessary.Ĭreate a new Windows Application using Visual Studio and C# as the programming language. In this example, you will learn to resize Windows Forms controls and forms automatically so that they fit their content. In this article, I am going to cover the following options: NET Framework 2.0 comes with several options to solve the problem of dynamic layout. In all such cases, being able to change the layout of your form dynamically becomes essential. Your application adds controls dynamically on the forms.You are developing a multilingual application and don’t know the width of controls under different language settings.You are setting the text of controls such as Label and Button via code and don’t know the length of the text at design time.You developed your application under one screen resolution and want to run it on machines having different (and possibly unknown) screen resolutions.There are many scenarios wherein you need dynamic layouts.
In this article, I am going to illustrate some of these techniques with examples. NET Framework 2.0 provides some handy techniques that allow you to provide dynamic layout to your forms. However, the task was certainly not an easy one. In the past, developers used various techniques to avoid such problems, including resizing controls at runtime by handling certain event handlers. If you are a long-time Windows developer, at some point in time you must have faced the difficulty in adjusting your forms and dialogs for multiple screen resolutions.
