Is there anyway to disable this?

I have not been able to repro this behavior.

It's caused by the AutoPostBack setting on SearchTextBox. Remove that attribute and this won't happen. My apologies for not figuring this out sooner.

When I had selected 'Control' as the Parameter Source value, automatic definition wrote 'Control' to the code. Right markup is:

<WhereParameters>

<asp:ControlParameter ControlID="DepartmentsDropDownList" Name="DepartmentID" PropertyName="SelectedValue" Type="Int32" />

</WhereParameters>

In sample Entity Framework is presented clearly. I like.

For integer properties, use PropertyExpression instead of SearchExpression. For an example, see msdn.microsoft.com/
