    <p>I have a <strong>drop down list</strong> (very long, over 100 items) inside the <strong>insert item template view</strong> for a details view. I would like to add a text box and button (search feature) so i can filter this list but i get the following error.</p> <blockquote> <p>Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control.</p> </blockquote> <p>I created two entity datasource, one with a where clause and the other one without. When I hit search, the code behind (button click event) switches the datasource to the one with the where clause and parameter but i get the error above. Any advice on how to go about doing this?</p> <pre><code>Dim aa As DropDownList = DetailsView1.FindControl("DropDownList1") aa.DataSourceID = "" aa.DataSource = EmpPersonalInfoLOV1 aa.DataBind() </code></pre> <p>EDITED <strong>Change aa.DataSource from a string to EmpPersonalInfoLOV1 (the name of the datasource)</strong></p> <p><em><strong>EDIT #2</em></strong> More info requested by users..</p> <p><strong>Datasource # 1 Code</strong></p> <pre><code>&lt;asp:EntityDataSource ID="EmpPersonalInfoLOV" runat="server" ConnectionString="name=sspEntities" DefaultContainerName="sspEntities" EnableFlattening="False" EntitySetName="Employee_Personal_Info" EntityTypeFilter="" Select="it.[Emp_id], it.[Employee_No_FastPay], it.[Surname] + ' '+ it.[Firstname] As FullName" Where=""&gt; &lt;/asp:EntityDataSource&gt; </code></pre> <p><strong>Datasource # 2 Code</strong> </p> <pre><code>&lt;asp:EntityDataSource ID="EmpPersonalInfoLOV1" runat="server" ConnectionString="name=sspEntities" DefaultContainerName="sspEntities" EnableFlattening="False" EntitySetName="Employee_Personal_Info" Select="it.[Emp_id], it.[Employee_No_FastPay], it.[Surname] + ' '+ it.[Firstname] As FullName" Where="it.Surname like '%' + @Name + '%'"&gt; &lt;WhereParameters&gt; &lt;asp:ControlParameter ControlID="TxtBx1" DbType="String" DefaultValue="&amp;quot;&amp;quot;" Name="Name" PropertyName="SelectedValue" /&gt; &lt;/WhereParameters&gt; &lt;/asp:EntityDataSource&gt; </code></pre>

    1. COI haven't done this in a while but I believe the `DataSource` should be an object not a string?

    3. COYou are setting aa.DataSource to a string value. You should set it to the actual datasource object

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.
