    <p>As i am able get Correct file Type for image as JPEG Image. But i can get file type for pdf document or sql file. I am using below code:</p> <pre><code>public String Type { get { return GetType(Path.GetExtension(_document.DocumentPath)); } } public static string ReadDefaultValue(string regKey) { using (var key = Microsoft.Win32.Registry.ClassesRoot.OpenSubKey(regKey, false)) { if (key != null) { return key.GetValue("") as string; } } return null; } public string GetType(string ext) { if (ext.StartsWith(".") &amp;&amp; ext.Length &gt; 1) ext = ext.Substring(1); var retVal = ReadDefaultValue(ext + "file"); if (!String.IsNullOrEmpty(retVal)) return retVal; using (var key = Microsoft.Win32.Registry.ClassesRoot.OpenSubKey("." + ext, false)) { if (key == null) return ""; using (var subkey = key.OpenSubKey("OpenWithProgids")) { if (subkey == null) return ""; var names = subkey.GetValueNames(); if (names == null || names.Length == 0) return ""; foreach (var name in names) { retVal = ReadDefaultValue(name); if (!String.IsNullOrEmpty(retVal)) return retVal; } } } return ""; } </code></pre> <p>As i have seen that there is no "OpenWithProgids" subkey in .pdf file in regedit. so what can do to get these file types.</p> <p>For Example In win 7<img src="https://i.stack.imgur.com/IDLWl.png" alt="enter image description here"></p> <p>file type listed with file name and with other information , I want that same file type in my application I am able to xps document but not other document</p>

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.
