public Style TextBoxStyle { get; }

Property Value

Type: System.Web.UI.WebControls.Style

A reference to the Style that contains properties that define the appearance of text boxes.

The TextBoxStyle property defines the appearance of the User name and Password TextBox controls in the Login control. This property is read-only; however, you can set the properties of the Style object it returns. You can set these properties declaratively in the form Property-Subproperty, where Subproperty represents a property of the Style class (for example, TextBoxStyle-ForeColor). You can set the property programmatically in the form Property.Subproperty (for example, TextBoxStyle.ForeColor).

Common settings include custom background color, text color, and font properties. The TextBoxStyle property defines the appearance of the user name and password text boxes.

The style settings for the TextBoxStyle property are merged with the style settings for the Login control. Any settings made in the TextBoxStyle property override the corresponding settings in properties of the Login control.

The following Login style properties are overridden by TextBoxStyle settings:

When you use templates to define the appearance of the Login control, the TextBoxStyle property has no effect.

The following code example sets the background and text colors of the User name and Password TextBox controls by setting properties on the Style object referenced by the TextBoxStyle property.

System_CAPS_security Security Note

This example contains a text box that accepts user input, which is a potential security threat. By default, ASP.NET Web pages validate that user input does not include script or HTML elements. For more information, see Script Exploits Overview.
