问题描述
开始之前,在.
您可以为控件创建一个新的设计器并覆盖该方法,并在调用基本方法后,将 Text
属性设置为空字符串.
The designer sets Text
property of control in InitializeNewComponent
of ControlDesigner
.
You can create a new designer for your control and override that method and after calling base method, set the Text
property to empty string.
通过这种方式,您的控件以空的 Text
属性开始,并且还可以在设计时使用属性网格更改 Text
的值.
This way your control starts with an empty Text
property and also you can change the value of Text
using property grid at design-time.
using System.ComponentModel;
using System.Windows.Forms;
using System.Windows.Forms.Design;
[Designer(typeof(MyControlDesigner))]
public partial class MyControl: Control
{
}
public class MyControlDesigner : ControlDesigner
{
public override void InitializeNewComponent(System.Collections.IDictionary defaultValues)
{
base.InitializeNewComponent(defaultValues);
PropertyDescriptor descriptor = TypeDescriptor.GetProperties(base.Component)["Text"];
if (((descriptor != null) && (descriptor.PropertyType == typeof(string))) && (!descriptor.IsReadOnly && descriptor.IsBrowsable))
{
descriptor.SetValue(base.Component, string.Empty);
}
}
}
