ASP.NET 设置/获取/清空 用户的剪贴板（How to copy/get/clear value to clipboard）

We can Set/Get/Clear users’ clipboard by the JavaScript window.clipboardData object, which only works in Internet Explorer, by the following code:
 
window.clipboardData.setData("text",value)
window.clipboardData.getData("text")
window.clipboardData.clearData("text")
 
If you need set a code-behind value to user’s clipboard, please pass it to JavaScript variable first, and then, set the value to clipboard. Or you can call the JavaScript from code-behind, just like the following code:

 

protected void Button1_Click(object sender, EventArgs e)
{
    string values = "hello world";
    ClientScript.RegisterStartupScript(this.GetType(), "copy", "window.clipboardData.setData('text','"+values+"')", true);
}

Thanks.
