    copied!<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>
