    <p>I have a problem with the code below, basically what is does is read from a path where files with extension .config are stored, it reads the names of the files without extension and displays them all in a combobox. That works fine and if you click on the down arrow and select a name it actually does what it's supposed to, however, once I have selected an item from the dropdown with the mouse and I go back and start typing inside the combobox my application crashes throwing a exception.</p> <p>I've tried adding a try-catch-finally but it keeps throwing the same error. Could it be the loop that is causing my application to crash once I start typing in the combobox?</p> <p>p.d. If I just use the mouse to select an item from the dropdown menu my application works fine but once I've selected an item with the mouse and use the keyboard to type another item name inside the combobox my app crashes. Any pointers would be helpful.</p> <pre><code>// Gets all the file names from the path assigned to templatePath // and assigns it to the string array fname string[] fname = Directory.GetFiles(templatePath); // Begin sorting through the file names assigned to the string array fname foreach (string file in fname) { // Remove the extension from the file names and compare the list with // the dropdown selected item if (System.IO.Path.GetFileNameWithoutExtension(file) == cbTemplates.SelectedItem.ToString()) { // StreamReader gets the contents from the found file and assigns // them to the labels using (var obj = new StreamReader(File.OpenRead(file))) { lbl1.Content = obj.ReadLine(); lbl2.Content = obj.ReadLine(); lbl3.Content = obj.ReadLine(); lbl4.Content = obj.ReadLine(); lbl5.Content = obj.ReadLine(); lbl6.Content = obj.ReadLine(); lbl7.Content = obj.ReadLine(); lbl8.Content = obj.ReadLine(); lbl9.Content = obj.ReadLine(); lbl10.Content = obj.ReadLine(); obj.Dispose(); } } } </code></pre>

    2. COYou should handle the case when the file is not exactly 10 lines. You don't need to call dispose on `obj`, because `using` does this. Can you add the code that uses the combobox?

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.
