ControlBuilder.ControlType Property

Gets the Type for the control to be created.

Namespace: System.Web.UI
Assembly: System.Web (in system.web.dll)

public Type ControlType { get; }
/** @property */
public Type get_ControlType ()

public function get ControlType () : Type

Not applicable.

Property Value

The Type for the control to be created.

This example overrides the OnAppendToParentBuilder method to check the ControlType property to determine what type of control this builder is applied to. If it is a CustomTextBox, the builder checks whether the value of the HasAspCode property is included in the control. If so, an exception is thrown, if not the HasBody method is called.

	public class AppendControlBuilder : ControlBuilder
	{
		// Override the OnAppendToParentBuilder method.
		public override void OnAppendToParentBuilder(ControlBuilder parentBuilder)
		{
            // Check whether the type of the control this builder
            // is applied to is CustomTextBox. If so, check whether
            // ASP code blocks exist in the control. If so, call
            // throw an Exception, if not, call the HasBody method.

					throw new Exception("This control cannot contain code blocks.");
				else
