    <p>I have a user control, a dropdown list, that's comprised of many component controls. The main HtmlInputText will post back on an enter but on loss of focus it doesn't and I need that to update other controls. I added an onblur function, and it gets called, but I only want to postback when the element getting focus isn't part of the user control. </p> <p>How do I determine what is selected and if it's a child of the control? </p> <p>Markup:</p> <pre><code> &lt;%@ Register Assembly="MultiDropDown" Namespace="MultiDropDownLib" TagPrefix="MultiDropDownLib" %&gt; &lt;asp:Content ID="HeaderContent" runat="server" ContentPlaceHolderID="HeadContent"&gt; &lt;/asp:Content&gt; &lt;asp:Content ID="BodyContent" runat="server" ContentPlaceHolderID="MainContent"&gt; &lt;table style="width: 328px"&gt; &lt;tr&gt; &lt;td&gt; ProductClass &lt;/td&gt; &lt;td&gt; &lt;MultiDropDownLib:MultiDropDown ID="MultiDropDown1" runat="server" TextBoxClass="textboxDD" PostOnBlur="true" /&gt; &lt;/td&gt; ... </code></pre> <p>And in the control:</p> <pre><code>if (PostOnBlur) { txtItemList.Attributes.Add("onblur", string.Format("PostBack();", this.ClientID)); } </code></pre> <p>In the PostBack I want to determine what has focus and if it's part of the control. The original control came from: <a href="http://www.codeproject.com/Articles/219977/MultiDropDown-A-multiple-selection-Dropdown-contro/%20%22MultiDropDown" rel="nofollow">http://www.codeproject.com/Articles/219977/MultiDropDown-A-multiple-selection-Dropdown-contro</a></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.
