    <p>I am searching XML files to see if there are contents which match the words inserted in these textboxes <code>txtComKeyword1</code>, <code>txtComKeyword2</code>, <code>txtComKeyword3</code> and/or <code>txtComKeyword4</code>. The function below is working, but may I know how can I highlight the keywords that user entered in the four textboxes that match that appear in my <code>richComResults</code> richtextbox?</p> <p>For example, my user will fill in those four textboxes ie. txtComKeyword1, txtComKeyword2, txtComKeyword3 and txtComKeyword4. Then, my code will parse the XML file to see if the nodes contain these four keywords, if yes, the nodes' data will be output on my richComResults, I wanna highlight those four keywords (eg txtComKeyword1=hello, txtComKeyword2=bye, txtComKeyword3=morning, txtComKeyword4=night). These 4 words, if found and appear in richComResults, will be highlighted with color.</p> <p>I have no clue after searching for a while, my case is much different from other questions. I am a newbie in programming, your help would be much appreciated. Thank you!</p> <p>My Code:</p> <pre><code>private void searchComByKeywords() { // Process the list of files found in the directory. string[] fileEntries = Directory.GetFiles(sourceDir); foreach (string fileName in fileEntries) { XmlDocument xmlDoc = new XmlDocument(); //* create an xml document object. string docPath = fileName; xmlDoc.Load(docPath); //* load the XML document from the specified file. XmlNodeList nodeList = xmlDoc.GetElementsByTagName("item"); foreach (XmlNode node in nodeList) { XmlElement itemElement = (XmlElement) node; string itemDescription = itemElement.GetElementsByTagName("description")[0].InnerText; if (txtComKeyword1.Text != (String.Empty) &amp;&amp; itemDescription.ToLower().Contains(txtComKeyword1.Text.ToLower()) || txtComKeyword2.Text != (String.Empty) &amp;&amp; itemDescription.ToLower().Contains(txtComKeyword2.Text.ToString()) || txtComKeyword3.Text != (String.Empty) &amp;&amp; itemDescription.ToLower().Contains(txtComKeyword3.Text.ToString()) || txtComKeyword4.Text != (String.Empty) &amp;&amp; itemDescription.ToLower().Contains(txtComKeyword4.Text.ToString())) { string itemTitle = itemElement.GetElementsByTagName("title")[0].InnerText; string itemDate = itemElement.GetElementsByTagName("pubDate")[0].InnerText; string itemAuthor = itemElement.GetElementsByTagName("author")[0].InnerText; richComResults.AppendText("Author: " + itemAuthor + "\nDate: " + itemDate + "\nTitle: " + itemTitle + "\nDescription: " + itemDescription + "\n\n--------\n\n"); } } } } </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.
