    <p><strong>Edit 3:</strong> </p> <p>The below code will work for static controls, but dynamically-created controls will not be preserved on postback. You will need to store the updated values so they can be retrieved on postback somehow (e.g. a Session variable or HiddenField). If possible, I would create the controls statically and populate them in <code>page_load</code>, hiding controls with no data - this would allow you to get the values on postback as below.</p> <hr> <p>Hmm...I set up a super simplified version of your code and ran it pretty much as is (without the database function), and it seems to be working fine. </p> <p>Here is the simplified version I used:</p> <pre><code>&lt;asp:Content id="Content1" ContentPlaceHolderID="MainContent" runat="server"&gt; &lt;asp:ImageButton ID="imgbtnSave" runat="server"&gt;&lt;/asp:ImageButton&gt; &lt;asp:PlaceHolder ID="PlanPlaceHolder" runat="server"&gt; &lt;asp:TextBox runat="server" ID="txtTrainingStart" value="before" &gt;&lt;/asp:TextBox&gt; &lt;/asp:PlaceHolder&gt; &lt;/asp:Content&gt; </code></pre> <p>Javascript:</p> <pre class="lang-js prettyprint-override"><code>function txtTrainingStart_Click(txtTrainingStart, txtTask) { var currentdate = new Date(); var test = "after"; txtTrainingStart.value = test; txtTrainingStart.style.backgroundColor = "yellow"; } </code></pre> <p>VB: </p> <pre><code>Protected Sub imgbtnSave_Click(ByVal sender As Object, ByVal e As ImageClickEventArgs Handles imgbtnSave.Click For Each item As TextBox In PlanPlaceHolder.Controls 'need updated textbox values here.' Debug.WriteLine(item.ID) Debug.WriteLine(item.Text) Next End Sub </code></pre> <p>I'm getting the updated value of the textbox, so you should be able to pass that value to a function and do whatever operations you need.</p> <p>Let me know if I'm missing something.</p> <p><strong>Edit 2:</strong> I just had a thought--can you check if <code>page_load</code> is being called after you click the save button? I wonder if it is overwriting your updated values with the original values again.</p> <p>If it is, I would wrap the database functionality in <code>page_load</code> with a postback check:</p> <pre><code>If Not IsPostBack ' connect to database' ' populate placeholder' End If </code></pre>

    1. CO1. When I change onClick to onClientClick my click events no longer fire. 2. I tried adding `__doPostBack('imgbtnSave','');` to the end of my javascript click events and this just causes the updates I just made to be removed. 3. I tried the update panel (also had to add a scriptmanager to my masterpage) but this doesn't do anything, same results as I had before, I am unable to pull the updated values.

    2. COI think I misunderstood your question, so I tested some code and rewrote my answer above.

    3. COYou are exactly right! The save button click is causing the `page_load` event to fire again thus overwriting my values. Problem is if I intercept it using `IsPostBack` in `page_load` the original page is already gone. I think maybe I need to use an update panel. I'll see what I can figure out and post what I find.

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.
