how to create a ComboBox in website c#
<p>I created a website in c# with visual studio 2015. I want that I have a DropDownList which offers me the possibility to write in the text zone,like writing in a TextBox..I have found that should be a ComboBox but I couldn't found thic component in my ToolBox in visual studio 2015..
This is the code of my DropDownList:</p>

<pre><code>&lt;asp:Label ID="Label4" text="Lastname :" runat="server"  ForeColor="#80FF00"&gt;&lt;/asp:Label&gt;&lt;br /&gt;
        &lt;asp:DropDownList ID="DropDownList1" runat="server"  Enabled="true"  Width="140px"  AutoPostBack="false"&gt;&lt;/asp:DropDownList&gt;
</code></pre>
