我想在MFC对话框中显示.NET图表控件。我通过CWinFormsControl实例使用了托管控件。在.NET端,我创建了一个带有文本框,按钮和图表控件的UserControl。
不幸的是,我无法设置Chart控件的属性。尽管可以识别Chart控件本身,但不能识别/访问其任何属性或方法。
在Forms / .NET中:
namespace HostableUserControl
{
partial class UserControl1
{
/// <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()
{
System.Windows.Forms.DataVisualization.Charting.ChartArea chartArea1 = new System.Windows.Forms.DataVisualization.Charting.ChartArea();
System.Windows.Forms.DataVisualization.Charting.Series series1 = new System.Windows.Forms.DataVisualization.Charting.Series();
this.button1 = new System.Windows.Forms.Button();
this.textBox1 = new System.Windows.Forms.TextBox();
this.chart1 = new System.Windows.Forms.DataVisualization.Charting.Chart();
((System.ComponentModel.ISupportInitialize)(this.chart1)).BeginInit();
this.SuspendLayout();
//
// button1
//
this.button1.Location = new System.Drawing.Point(39, 25);
this.button1.Name = "button1";
this.button1.Size = new System.Drawing.Size(75, 23);
this.button1.TabIndex = 0;
this.button1.Text = "button1";
this.button1.UseVisualStyleBackColor = true;
//
// textBox1
//
this.textBox1.Location = new System.Drawing.Point(140, 163);
this.textBox1.Name = "textBox1";
this.textBox1.Size = new System.Drawing.Size(98, 20);
this.textBox1.TabIndex = 1;
this.textBox1.TextChanged += new System.EventHandler(this.textBox1_TextChanged);
//
// chart1
//
this.chart1.BorderSkin.SkinStyle = System.Windows.Forms.DataVisualization.Charting.BorderSkinStyle.FrameThin1;
chartArea1.Name = "ChartArea1";
this.chart1.ChartAreas.Add(chartArea1);
this.chart1.Location = new System.Drawing.Point(140, 23);
this.chart1.Name = "chart1";

this.Controls.Add(this.chart1);
this.Controls.Add(this.textBox1);
this.Controls.Add(this.button1);
this.Name = "UserControl1";
this.Size = new System.Drawing.Size(394, 200);
((System.ComponentModel.ISupportInitialize)(this.chart1)).EndInit();
this.ResumeLayout(false);
this.PerformLayout();
}
#endregion
public System.Windows.Forms.Button button1;
public System.Windows.Forms.TextBox textBox1;
public System.Windows.Forms.DataVisualization.Charting.Chart chart1;
}
}
//在MFC中(代码段):
CWinFormsControl<HostableUserControl::UserControl1> m_ctrl1;
{
m_ctrl1.GetControl()->textBox1->Text = "hello world"; // this works
m_ctrl1.GetControl()->chart1->Text = "hello world"; // this generates compiler error
}
编译器错误(VS2017):
错误C2039:“文本”:不是System :: Windows :: Forms :: DataVisualization :: Charting :: Chart'的成员
此错误是针对Chart的所有公共成员生成的。
有什么建议吗?
