    <p>I have a couple of <code>DropDownLists</code> in my <code>GridView</code> from customer table that binds the selected value from my db. </p> <p>I noticed that if I only have one customer and would like to edit that customers gender it's not possible because I populate the <code>DropDownLists</code> with the SELECT DISTINCT Gender FROM Customer and my first customer is either Herr or Frau and I can only choose from that value. </p> <p>I was thinking I could solve this Problem using a Union select <code>select Gender from ( select Gender = 'Herr' union select Gender = 'Frau' )as Gender </code> to bring both alternatives but then i get this error message 'DropDownList1'** has a SelectedValue which is invalid because it does not exist in the list of items**</p> <p>So my question is how can I add some alternatives to <code>DropDownLists</code>that's not already presented in DB and still bind the <code>SelectedValue</code>?</p> <pre><code>&lt;EditItemTemplate&gt; &lt;asp:DropDownList ID="DropDownList3" runat="server" DataSourceID="SqlDataSource1" DataTextField="Gender" DataValueField="Gender" SelectedValue='&lt;%# Bind("Gender") %&gt;'&gt; &lt;/asp:DropDownList&gt; &lt;asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="&lt;%$ ConnectionStrings:EventConnectionString %&gt;" SelectCommand="SELECT DISTINCT [Gender] FROM [Customer]"&gt;&lt;/asp:SqlDataSource&gt; &lt;/EditItemTemplate&gt; &lt;ItemTemplate&gt; &lt;asp:Label ID="Label2" runat="server" Text='&lt;%# Bind("Gender") %&gt;'&gt;&lt;/asp:Label&gt; &lt;/ItemTemplate&gt; </code></pre> <hr> <p>Thanks for your answers, what do I Need to Change in code behind to make it work? </p> <p>Here is my code behind.</p> <pre><code>protected void Page_Load(object sender, EventArgs e) { } protected void lbInsert_Click(object sender, EventArgs e) { Event.InsertParameters["Gender"].DefaultValue = ((DropDownList)GridView1.FooterRow.FindControl("ddlGender")).SelectedValue; Event.InsertParameters["LastName"].DefaultValue = ((TextBox)GridView1.FooterRow.FindControl("txtLastName")).Text; Event.InsertParameters["FirstName"].DefaultValue = ((TextBox)GridView1.FooterRow.FindControl("txtFirstName")).Text; Event.InsertParameters["Street"].DefaultValue = ((TextBox)GridView1.FooterRow.FindControl("txtStreet")).Text; Event.InsertParameters["HouseNr"].DefaultValue = ((TextBox)GridView1.FooterRow.FindControl("txtHouseNr")).Text; Event.InsertParameters["Zip"].DefaultValue = ((TextBox)GridView1.FooterRow.FindControl("txtZip")).Text; Event.InsertParameters["City"].DefaultValue = ((TextBox)GridView1.FooterRow.FindControl("txtCity")).Text; Event.InsertParameters["Phone"].DefaultValue = ((TextBox)GridView1.FooterRow.FindControl("txtPhone")).Text; Event.InsertParameters["Email"].DefaultValue = ((TextBox)GridView1.FooterRow.FindControl("txtEmail")).Text; Event.InsertParameters["Company"].DefaultValue = ((TextBox)GridView1.FooterRow.FindControl("txtCompany")).Text; Event.InsertParameters["Active"].DefaultValue = ((DropDownList)GridView1.FooterRow.FindControl("ddlActive")).SelectedValue; Event.Insert(); } </code></pre>

Guidance
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.
