    <p>I actually have two questions: </p> <p>(1) Is it possible to put <em>another</em> image on top of an ImageButton that already has an ImageUrl set (without changing the ImageUrl - literally just add the second image 'on top')? Even by using CSS?</p> <p>(2) I have a dynamically set number of ImageButtons contained within a ListView. When a user clicks on an ImageButton, I change the <code>.CssClass</code> property of the one clicked in order to 'highlight' it. My question is this: whenever an ImageButton is click, I need to not only highlight it, but make sure I <em>unhighlight</em> all the others. However, I'm having trouble getting the others. I get the clicked ImageButton using</p> <pre><code>((ImageButton)sender).CssClass = "SelectedImageButton"; </code></pre> <p>in the event handler. However, how do I get all the others so I can set their style 'back' to the unhighlighted style?</p> <p>Thanks in advance for any help!</p> <p><strong>UPDATE: ANSWERED!</strong> I've solved the issue mentioned in (2) using the following algorithm. Note, I've marked @OFConsulting's answer below as the correct answer because without his algorithm, I would have never gotten the following algorithm (which came from tweaking his algorithm slightly). Thanks @OFConsulting!</p> <pre><code>// Cast the sender to an ImageButton to have the clicked ImageButton ImageButton clickedImageButton = sender as ImageButton; // The ListView has ListViewDataItems and the ImageButtons are in // THOSE children controls, thus match on the ImageButtons' Parents' IDs Control parentControl = clickedImageButton.Parent; List&lt;ListViewDataItem&gt; allOtherImageButtons = MyListView.Controls.OfType&lt;ListViewDataItem().AsQueryable().Where(i =&gt; i.ID != clickedImageButton.Parent.ID).ToList(); // Highlight clickedImageButton.CssClass = "HighlightedStyle"; // Unhighlight foreach (ListViewDataItem button in allOtherImageButtons) { // The ImageButton is always the 2nd child control of the ListViewDataItem ImageButton childImageButton = (ImageButton)button.Controls[1]; childImageButton.CssClass = "NoHighlightedStyle"; } </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.
