    <p><strong>My Program:</strong> Contains a form with few textboxes and one button. 'Default Printer' is set as <em>Adobe PDF</em> on my computer.</p> <p><strong>My Goal:</strong> Want to take a screenshot of a form/usercontrol when the user clicks 'Print' button. The screenshot is then saved on the desktop in .pdf format.</p> <p><strong>My Problem:</strong> I have following two problems with the code:</p> <ol> <li><strong>Size of Screenshot:</strong> The size of the screenshot is too big and it does not fit the size of the page (default page size) when printed/converted to <em>.pdf</em>. Please refer the two images below. I want the entire screenshot to fit inside the page.</li> <li><strong>Asks twice where to convert and save:</strong> When I click on 'Print Form' button, programs asks me TWICE where to print/convert and save the file. I want the program to ask me only Once, where to print and save the file.</li> </ol> <p>Problem 1: The screenshot captured by the program does not fit the page when printed. <img src="https://i.stack.imgur.com/auGBB.png" alt="Problem 1: The screenshot captured by the program does not fit the page when printed."></p> <p>I want the screenshot image to fit like this on one page of <em>.pdf</em>: <img src="https://i.stack.imgur.com/7FP3j.png" alt="enter image description here"></p> <p><strong>Code:</strong></p> <pre><code>public partial class Form1 : Form { public Form1() { InitializeComponent(); button1.Text = "Print Form"; button1.Click += new EventHandler(button1_Click); printDocument1.PrintPage += new PrintPageEventHandler(printDocument1_PrintPage); this.Controls.Add(button1); } private void button1_Click(object sender, EventArgs e) { CaptureScreen(); printDocument1.Print(); } Bitmap memoryImage; private void CaptureScreen() { Graphics myGraphics = this.CreateGraphics(); Size s = this.Size; memoryImage = new Bitmap(s.Width, s.Height, myGraphics); Graphics memoryGraphics = Graphics.FromImage(memoryImage); memoryGraphics.CopyFromScreen(this.Location.X, this.Location.Y, 0, 0, s); } private void printDocument1_PrintPage(System.Object sender, System.Drawing.Printing.PrintPageEventArgs e) { e.Graphics.DrawImage(memoryImage, 0, 0); } } </code></pre> <p>Thanks for your help in advance. I am a newbie, learning c# language and your help will be much appreciated. :)</p>

    2. COFor the 2nd issue (double dialog), this is just a guess but try removing this line `printDocument1.PrintPage += ...` from your constructor. I'm guessing that this already happens inside of `InitializeComponent()` which means that you are explicitly handling the event twice. Open your Form1.Designer.cs file to see if there are other things you're duplicating. (Except for your Init call everything else in the constructor may be redundant.)

    3. CO@PaulSasik: Nope. For problem 2, removing that line gives me a white PDF and cannot save it. ._.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
