我有一个这样创建的控件:
public partial class MYControl : MyControlBase
{
public string InnerText {
get { return textBox1.Text; }
set { textBox1.Text = value; }
}
public MYControl()
{
InitializeComponent();
}
}
partial class MYControl
{
/// <summary>
/// Required designer variable.
/// </summary>
private System.ComponentModel.IContainer components = null;
/// <summary>
/// Clean up any resources being used.
/// </summary>
/// <param name="disposing">true if managed resources should be disposed; otherwise, false.</param>
protected override void Dispose(bool disposing)
{
if (disposing && (components != null))
{
components.Dispose();
}
base.Dispose(disposing);
}
#region Component Designer generated code
/// <summary>
/// Required method for Designer support - do not modify
/// the contents of this method with the code editor.
/// </summary>
private void InitializeComponent()
{
this.textBox1 = new System.Windows.Forms.TextBox();
this.listBox1 = new System.Windows.Forms.ListBox();
this.label1 = new System.Windows.Forms.Label();
this.SuspendLayout();
//
// textBox1
//
this.textBox1.Location = new System.Drawing.Point(28, 61);
this.textBox1.Name = "textBox1";
this.textBox1.Size = new System.Drawing.Size(100, 20);
this.textBox1.TabIndex = 0;
//
// listBox1
//
this.listBox1.FormattingEnabled = true;
this.listBox1.Location = new System.Drawing.Point(7, 106);
this.listBox1.Name = "listBox1";
this.listBox1.Size = new System.Drawing.Size(120, 95);
this.listBox1.TabIndex = 1;
//
// label1
//
this.label1.AutoSize = true;
this.label1.Location = new System.Drawing.Point(91, 42);
this.label1.Name = "label1";
this.label1.Size = new System.Drawing.Size(35, 13);
this.label1.TabIndex = 2;
this.label1.Text = "label1";
//
// MYControl
//
this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 13F);
this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;
this.Controls.Add(this.label1);
this.Controls.Add(this.listBox1);
this.Controls.Add(this.textBox1);
this.Name = "MYControl";
this.Size = new System.Drawing.Size(135, 214);
this.ResumeLayout(false);
this.PerformLayout();
}
#endregion
private System.Windows.Forms.Label label1;
}
MyControlBase 包含 ListBox 和 TextBox 的定义。现在,当我尝试在表单设计器中查看此控件时,它给了我这些错误:
变量“listBox1”要么未声明,要么从未赋值。
变量“textBox1”要么未声明,要么从未赋值。
这显然是错误的,因为它们是在具有公共访问权限的 MyControlBase 中定义的。有什么方法可以让表单设计器让我直观地编辑我的控件?
