Hi All , I Have Create one Merge Pdf File, within that file i would like to add stamp to all pages, i have tried lots, but nver got the solution, please ... the form, and set its CausesValidation property set to false. However, this is only part of the solution. By setting CausesValidation to false, you allow the focus to change to the Cancel button, and you allow its Button.Click event to fire. However, when your code uses the Form.Close() method to close the form, the validation code still springs into action, preventing the form from closing. private void cmdClose_Click(object sender, EventArgs e) { // This triggers validation. this.Close(); } There are two solutions. The first choice is to change the Form.AutoValidate setting before you attempt to close the form. For example, this event handler will breeze past any validation routines: private void cmdClose_Click(object sender, EventArgs e) { this.AutoValidate = AutoValidate.Disable; this.Close(); } There s another option. When the validation code sets the cancel flag, it indicates that the form should not be allowed to close. However, you still have the chance to override this decision by handling FormClosing. At this point, you can clear the cancel flag if you want, allowing the form to close. Here s an example that lets the user decide: private void Form1_FormClosing(object sender, FormClosingEventArgs e) { // If e.Cancel is true, the cancel flag has been set by a validation routine. if (e.Cancel) { DialogResult result = MessageBox.Show( "There are still errors on the form. Do you wish to close the form ", "Errors found", MessageBoxButtons.YesNo); if (result == DialogResult.Yes) e.Cancel = false; } } This approach is quite a bit different than the first solution, because it ensures that your validation code runs. add watermark text to pdf using itextsharp c#: c# itextsharp PDF creation with watermark on each page - Stack ... add image watermark to pdf c# Using iTextSharp To Watermark /Write Text To Existing PDF's ...

The .NET Framework provides an elegant way to accomplish this: ErrorProvider control. The ErrorProvider has a simple role in life it can display an error icon (which looks like a red exclamation point) next to any control. Typically, you ll show the error icon next to a control that has invalid input. You ll also specify a detailed text message. The error message appears in a tooltip if the user hovers over the error icon with the mouse pointer (see Figure 18-3). This chapter summarized the main features of Java 3D, including its many strengths (the scene graph, performance, its unique features, integration with Java, and an extensive body of documentation and examples). I examined the criticisms of Java 3D (i.e., being too high-level, not being used for real games, and having a lack of support), and found them to be groundless. I finished by briefly listing some of the alternatives to Java 3D; the most popular, JOGL, is the subject of s 15 through 17. This chapter contains many URLs leading to more information on Java 3D, including games, model loaders, and games-related libraries. Figure 18-3. The ErrorProvider The ErrorProvider is a provider control a special type of user-interface ingredient introduced in 4. Like all other providers, you add a single instance of the ErrorProvider to the form you want to validate. You can then use that instance to display an error icon next to any control. To add the ErrorProvider, you can drag it from the Toolbox into the component tray, or you can create it manually in code. In the latter case, make sure you create a member variable to track it so you can access it later. add watermark image to pdf using itextsharp c# Add Text Watermark and Image Watermark to PDF in C# .NET ...
