private　Unit　unitTextBoxHeight　=　Unit.Empty;
[Category("LabelTextBox")]
[Description("文本框宽度")]
public　Unit　TextBoxHeight
{
　　 get
　　 {
　　　　 this.EnsureChildControls();
　　　　 return　this.tb.Height;
　　 }
　　 set
　　 {
　　　　 this.EnsureChildControls();
　　　　 this.tb.Height　=　value;
　　 }
}

The Validateexpression property is primarily used to set the validation expression for the validation child control, and the property value is a string type. This is to expose the validation child control interface directly to the field control, for example, if you want to validate a field that represents the input message, you can set the value to: "\w+" ([-+.] \w+) *@\w+ ([-.] \w+) * \.\w+ ([-.] \w+) * "(indicates the regular expression of an e-mail) to verify that the user input value is a legitimate e-mail format. Validation expression does not belong to the content of this book to introduce, General ASP. NET related books will be introduced.
