C#实现运行期控件设计

最近看到很多人对C#运行期控件设计的问题于是写了这个Memo希望对大家有用

实现了控件自由拖动

实现了控件的拖动创建右键删除等类似IDE的控件创建当然更多功能靠大家自己完善

实现属性框与控件的绑定可以在运行期修改控件的Text

以下是部分代码

privatevoidbutton_Click(objectsenderEventArgse)

{

//控件框的显示与隐藏

if(panelVisible==true)

{

buttonText=+控件框;

panelVisible=false;

}

else

{

buttonText=控件框;

panelVisible=true;

}

}

private void button<fp class='fp-mca3f'></fp>_Click(object sender<fp class='fp-3wklu'></fp> EventArgs e){//控件框的显示与隐藏if (panel<fp class='fp-1kngi'></fp><fp class='fp-ht9y8'></fp>Visible == true){button<fp class='fp-zdrlb'></fp><fp class='fp-08zgu'></fp>Text = <fp class='fp-qodbl'></fp>+ 控件框<fp class='fp-qodbl'></fp>;panel<fp class='fp-oo78r'></fp><fp class='fp-ht9y8'></fp>Visible = false;}else{button<fp class='fp-5r0l1'></fp><fp class='fp-6fhn7'></fp>Text = <fp class='fp-rjk64'></fp><fp class='fp-l5b6e'></fp> 控件框<fp class='fp-w2mbb'></fp>;panel<fp class='fp-oo78r'></fp><fp class='fp-6fhn7'></fp>Visible = true;}}
