    <p>I want to add Server-Side controls (<code>CheckBoxList</code>s &amp; <code>Button</code>): </p> <p><code>ChkBoxLst1</code> &amp; <code>ChkBoxLst2</code> &amp; <code>Button1</code> through Code-behind and then use an <code>HTMLTextWriter</code> to render the control. </p> <p>I can't seem to be able to do this. </p> <p>All of the above in a Visual WebPart. </p> <p>What I have tried: <br /> Global: <br /></p> <pre><code>CheckBoxList ChkBoxLst2 = new CheckBoxList(); Button Bttn2 = new Button(); Label lbl2 = new Label(); StringWriter stringWriter = new StringWriter(); </code></pre> <p>Page Load:<br /></p> <pre><code>using (HtmlTextWriter writer = new HtmlTextWriter(stringWriter)) { ChkBoxLst2.Items.Add(new ListItem("Three", "3")); ChkBoxLst2.Items.Add(new ListItem("Four", "4")); ChkBoxLst2.RenderControl(writer); lbl2.RenderControl(writer); Bttn2.Click += new EventHandler(this.Bttn2_Click); Bttn2.Text = "Click this HTMLText WriteButton!"; Bttn2.RenderControl(writer); } spn.InnerHtml = stringWriter.ToString(); </code></pre> <p>Event Handler: <br/></p> <pre><code> void Bttn2_Click(Object sender, EventArgs e) { foreach (ListItem item in ChkBoxLst2.Items) { if (item.Selected == true) { if (IsPostBack) { lbl.Text += item.Text + ", "; } } } } </code></pre> <p>The EventHandler does not get triggered and the selected values do not get saved the way I have done it above. Any ideas as to why not? I've tried a comparison of two checkbox lists, but the <code>HTMLTextWriter</code> implementation did not work whereas the simple .NET did of the same thing <br/> all in all I think its my implementation of an HTMLTextWriter/how I add the server control.<br> <br /> Note that the spn is a literal span control in the markup. </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.
