I have created rectangle using PdfContentByte. Now I want to adda text inside this rectangle. How can I do this. If anybody have idea please share with me.My rectangle code is

 Document doc = new Document(new Rectangle(570, 924f));
 PdfWriter writer = PdfWriter.GetInstance(doc,Response.OutputStream);
 PdfContentByte cb = writer.DirectContent;
 cb.Rectangle(doc.PageSize.Width -90f, 830f, 50f,50f);
 cb.Stroke();

You are drawing a rectangle like this:

 PdfContentByte cb = writer.DirectContent;
 cb.Rectangle(doc.PageSize.Width -90f, 830f, 50f,50f);
 cb.Stroke();

This corresponds with this Rectangle:

Rectangle rect = new Rectangle(
    doc.PageSize.Width - 90f, 830f,
    doc.PageSize.Width - 40f, 880f);

You can add text inside this rectangle like this:

 ColumnText ct = new ColumnText(cb);
 ct.SetSimpleColumn(rect);
 ct.AddElement(new Paragraph("This is the text added in the rectangle"));
 ct.Go();
