单击按钮处理事件

Question

I am making a button in C# 4.0. I want to click this button and I want to open a dialog box inside the adobe reader. So I am making use of itextsharp also. Please let me know what must I use to make this dialog box work?

PushbuttonField button1 = new PushbuttonField(
    stamper.Writer,
    new Rectangle(90, 660, 140, 690), "Add Context");
button1.Text = "Add Context";

Answer 1

Assuming that you have inherited from the base Button class , you can do:

this.button1.Click += new EventHandler(button1_Click);
//there you have an event:
private void button1_Click(object sender, EventArgs e)
{
   //open the dialog box here...
}

Answer 2

button1.Text = "Add Context";
button1.Click += new EventHandler(button_Click);

protected void button_Click (object sender, EventArgs e)
{ 
//  perform necessary actions
}

Answer 3

The previous answers don't match the question.

The question is about a button in a PDF file. When somebody clicks on this button a dialog box needs to open.

The answers are about buttons in a C# application. There's a huge difference between a button in such an application and a button in Adobe Reader.

The question can't be answered in its current phrasing because it's not clear what you want to do with the dialog box in Adobe Reader. If you want a simple alert message, that's easy to achieve. If you expect you can create a dialog box with the same level of functionality available in a C# application, please forget the idea: you may be asking something that is completely impossible.
