ASP.NET SelectedValue which is invalid because it does not exist in the list of items. Parameter name: value
<p>I got error for DropDownList11 that say "'DropDownList11' has a SelectedValue which is invalid because it does not exist in the list of items.
Parameter name: value". The other dropdownlists with SQLDatasource work fine. I manually create this dropdownlist in edit DetailsView. Once it selected and click update, it will send it to SQL Server. Please help! Here a Code,</p>

<pre><code>&lt;EditItemTemplate&gt;
                    &lt;asp:DropDownList ID="DropDownList11" runat="server" SelectedValue='&lt;%# Bind("Version") %&gt;'&gt;
                        &lt;asp:ListItem Selected="True"&gt;&lt;/asp:ListItem&gt;
                        &lt;asp:ListItem&gt;Oracle 11g&lt;/asp:ListItem&gt;
                        &lt;asp:ListItem&gt;Oracle 11g R2&lt;/asp:ListItem&gt;
                        &lt;asp:ListItem&gt;Server 2008&lt;/asp:ListItem&gt;
                        &lt;asp:ListItem&gt;Server 2008 R2&lt;/asp:ListItem&gt;
                        &lt;asp:ListItem&gt;Server 2012&lt;/asp:ListItem&gt;
                        &lt;asp:ListItem&gt;SQL Svr 2008 R2 SS%S&lt;/asp:ListItem&gt;
                        &lt;asp:ListItem&gt;SQL Svr 2012 SS%S&lt;/asp:ListItem&gt;
                    &lt;/asp:DropDownList&gt;
                &lt;/EditItemTemplate&gt;
