    I am using NeedDataSource to databind a RadGrid to a collection of Entities using the Entity Framework 4.

    protected void dgPerson_NeedDataSource(object source, GridNeedDataSourceEventArgs e)
                dgPerson.DataSource = LocalEntityManager.Context.People;

    That all works fine but the StartsWith and EqualTo filter option do not return any rows. I have tried setting EnableLinqExpression to true and false but it makes no difference. There are 65,000 objects in this list of people objects. Could it be that is too many to filter by?

    <telerik:RadGrid ID="dgPerson" runat="server"
            <HeaderStyle Width="20px"></HeaderStyle>
            <HeaderStyle Width="20px"></HeaderStyle>
            <telerik:GridSortExpression FieldName="FullName" SortOrder="Ascending" />
            <telerik:GridBoundColumn DataField="PersonID" DataType="System.Int32" FilterControlWidth="40px"
                HeaderText="ID" ReadOnly="True" SortExpression="PersonID" UniqueName="PersonID">
            <telerik:GridTemplateColumn HeaderText="Full Name" SortExpression="FullName" UniqueName="FullName" DataField="FullName" AutoPostBackOnFilter="true" CurrentFilterFunction="StartsWith">
                <ItemTemplate><asp:Literal runat="server" ID="litFullName" Text='<%# Eval("FullName") %>'></asp:Literal></ItemTemplate>
                <EditItemTemplate><asp:TextBox runat="server" ID="txtFullName" Width="300px" Text='<%# Bind("FullName") %>'></asp:TextBox></EditItemTemplate>

    Hi Curtis,

    Are the other filtering options working correct?
    This could be a case sensitivity issue if the first letter in your records is in upper case and you write the text in filter in lower case.
    Try to set CaseSensitive="false" in the GroupingSettings of the grid.
