How to create a TextBox in WPF and C#

The TextBox element represents a WPF TextBox control in XAML.

<TextBox/>

The Width and Height attributes of the TextBox element represent the width and the height of a TextBox. The Text property of the TextBox element sets the content of a TextBox. The Name attribute represents the name of the control, which is a unique identifier of a control.

The code snippet in Listing 1 creates a TextBox control and sets the name, height, width, and content of a TextBox control.

 <TextBox Name="TextBox1" Height="30" Width="200" 
        Text="Hello! I am a TextBox.">           
</TextBox>

Listing 1

We can place a TextBox control where we want by using the Margin, VerticalAlignment and HorizontalAlignment attributes that sets the margin, vertical alignment, and horizontal alignment of a control.

The code snippet in Listing 2 sets the position of the TextBox control in the left top corner of the page.

<TextBox Name="TextBox1" Height="30" Width="200" 
        Text="Hello! I am a TextBox." 
        Margin="10,10,0,0" VerticalAlignment="Top" 
        HorizontalAlignment="Left">           
</TextBox>
