Dock property of control in c#

You can set the control borders to docked to its parent control through Dock property. Dock property of any control determines how a control is resized with its parent control.means how a control automatically resized as its parent control is resized. for example if you set the dock property of a control to Left, then it automatically align with the left side of its parent and it will automatically resize as the parent control is resized.

Dock property
Dock Locations

There is one point to need consider here that Anchor and Dock properties are mutually exclusive. Only one can be set at a time and the last one set takes precedence.


The following c# example creates a Panel and sets some of its common properties and then set the Dock property of this to Top.
and then set the Dock property of this to Top.

private void CreatePanelAndSetDock()
	Panel Pnl = new Panel();
	Pnl.BackColor = Color.Gray;
	Pnl.Height = 50;
	Pnl.BorderStyle = BorderStyle.Fixed3D;
	Pnl.Dock = DockStyle.Top;

Character casing in Textbox control

You can use the CharacterCasing property of the TextBox control in .net to change the case of characters as required by your application. For example,
you could change the case of all characters entered in a TextBox control used for username and password. When user can enter some textbox in both textbox, these textbox automatically change the text into upper case.
This example requires two textbox (txtUsername, txtPassword) and one button(see in the picture).
we can set the CharacterCasing property of the TextBox control through designer window as well as code.




txtUsername.CharacterCasing = CharacterCasing.Upper
txtPassword.CharacterCasing = CharacterCasing.Upper


txtUsername.CharacterCasing = CharacterCasing.Upper;
txtPassword.CharacterCasing = CharacterCasing.Upper;
