    <p>I have quite complicated set of HTML that I want to trawl looking for inputs that match various criteria. I hope to use something along the lines of:</p> <pre><code>private void setup() { masterContainer.InnerHtml = @" &lt;div&gt;crazy &lt;div&gt;unknown &lt;div&gt;html layout &lt;select id='crazySelectIdentifier_id1' runat='server'&gt; &lt;option value='1'&gt;Item1&lt;/option&gt; &lt;option value='2'&gt;Item2&lt;/option&gt; &lt;/select&gt; &lt;/div&gt; &lt;/div&gt; &lt;/div&gt; &lt;div&gt; &lt;div&gt; &lt;select id='crazySelectIdentifier_id2' runat='server'&gt; &lt;option value='1'&gt;Item1&lt;/option&gt; &lt;option value='2'&gt;Item2&lt;/option&gt; &lt;/select&gt; &lt;/div&gt; &lt;/div&gt; &lt;div&gt; &lt;/div&gt;"; } private void recursiveTrawl(HtmlGenericControl currentOuterControl) { for (int i = 0; i &lt; currentOuterControl.Controls.Count; i++) { HtmlGenericControl currentControl = (HtmlGenericControl) currentOuterControl.Controls[i]; if(currentControl.HasControls()) { recursiveTrawl(currentControl); } else { String[] controlArr = currentControl.ID.ToString().Split('_'); String currentId = controlArr[1]; if (currentId.Equals("somethingspecific")) { //THE PROBLEM IS HERE DropDownList dropdown = (DropDownList)currentControl; </code></pre> <p>However, I get the error- Cannot convert type 'System.Web.UI.HtmlControls.HtmlGenericControl' to 'System.Web.UI.WebControls.DropDownList'</p> <p>I've tried using HtmlSelect as well with a similiar error. I just need to know how I can get access to the selected values in the drop down lists I'm interested in.</p> <p>Thanks in advance.</p>

    1. COAre you trying to convert raw html into asp.net controls? What do you mean "trawl"? Is the page running the code, or are you statically parsing it?

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.
