    <p>I am using iTextSharp to read text contents from PDF. I am able to read that also. But I am loosing text formatting like the font, color etc. Is there any way to get that formatting as well.</p> <p>Below is the code segment i am using to exact text - </p> <pre><code>PdfReader reader = new PdfReader("F:\\EBooks\\AspectsOfAjax.pdf"); textBox1.Text = ExtractTextFromPDFBytes(reader.GetPageContent(1)); private string ExtractTextFromPDFBytes(byte[] input) { if (input == null || input.Length == 0) return ""; try { string resultString = ""; // Flag showing if we are we currently inside a text object bool inTextObject = false; // Flag showing if the next character is literal e.g. '\\' to get a '\' character or '\(' to get '(' bool nextLiteral = false; // () Bracket nesting level. Text appears inside () int bracketDepth = 0; // Keep previous chars to get extract numbers etc.: char[] previousCharacters = new char[_numberOfCharsToKeep]; for (int j = 0; j &lt; _numberOfCharsToKeep; j++) previousCharacters[j] = ' '; for (int i = 0; i &lt; input.Length; i++) { char c = (char)input[i]; if (inTextObject) { // Position the text if (bracketDepth == 0) { if (CheckToken(new string[] { "TD", "Td" }, previousCharacters)) { resultString += "\n\r"; } else { if (CheckToken(new string[] {"'", "T*", "\""}, previousCharacters)) { resultString += "\n"; } else { if (CheckToken(new string[] { "Tj" }, previousCharacters)) { resultString += " "; } } } } // End of a text object, also go to a new line. if (bracketDepth == 0 &amp;&amp; CheckToken( new string[]{"ET"}, previousCharacters)) { inTextObject = false; resultString += " "; } else { // Start outputting text if ((c == '(') &amp;&amp; (bracketDepth == 0) &amp;&amp; (!nextLiteral)) { bracketDepth = 1; } else { // Stop outputting text if ((c == ')') &amp;&amp; (bracketDepth == 1) &amp;&amp; (!nextLiteral)) { bracketDepth = 0; } else { // Just a normal text character: if (bracketDepth == 1) { // Only print out next character no matter what. // Do not interpret. if (c == '\\' &amp;&amp; !nextLiteral) { nextLiteral = true; } else { if (((c &gt;= ' ') &amp;&amp; (c &lt;= '~')) || ((c &gt;= 128) &amp;&amp; (c &lt; 255))) { resultString += c.ToString(); } nextLiteral = false; } } } } } } // Store the recent characters for when we have to go back for a checking for (int j = 0; j &lt; _numberOfCharsToKeep - 1; j++) { previousCharacters[j] = previousCharacters[j + 1]; } previousCharacters[_numberOfCharsToKeep - 1] = c; // Start of a text object if (!inTextObject &amp;&amp; CheckToken(new string[]{"BT"}, previousCharacters)) { inTextObject = true; } } return resultString; } catch { return ""; } } private bool CheckToken(string[] tokens, char[] recent) { foreach(string token in tokens) { if ((recent[_numberOfCharsToKeep - 3] == token[0]) &amp;&amp; (recent[_numberOfCharsToKeep - 2] == token[1]) &amp;&amp; ((recent[_numberOfCharsToKeep - 1] == ' ') || (recent[_numberOfCharsToKeep - 1] == 0x0d) || (recent[_numberOfCharsToKeep - 1] == 0x0a)) &amp;&amp; ((recent[_numberOfCharsToKeep - 4] == ' ') || (recent[_numberOfCharsToKeep - 4] == 0x0d) || (recent[_numberOfCharsToKeep - 4] == 0x0a)) ) { return true; } } return false; } </code></pre>

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.
