The example below demonstrates how to unselect rows hidden by the filter in the Grid View control:

<dx:ASPxGridView ID="Grid" runat="server" DataSourceID="ProductsDataSource" KeyFieldName="OrderID">
    <Settings ShowFilterRow="true" />
    <Columns>
        <dx:GridViewCommandColumn ShowSelectCheckbox="true" />
        <dx:GridViewDataSpinEditColumn FieldName="UnitPrice" />
        <dx:GridViewDataSpinEditColumn FieldName="Quantity" />
        <dx:GridViewDataSpinEditColumn FieldName="Discount" />
    </Columns>
</dx:ASPxGridView>
<dx:ASPxButton runat="server" id="ASPxButton1" Text="Unselect rows hidden by the filter" 
    OnClick="UnselectFilteredOutRows">
</dx:ASPxButton>

protected void UnselectFilteredOutRows(object sender, EventArgs e) {
    List<object> selectedKeys = Grid.GetSelectedFieldValues(Grid.KeyFieldName);
    List<object> filteredSelectedKeys = Grid.GetFilteredSelectedValues(Grid.KeyFieldName);
    foreach(var selectedKey in selectedKeys)
        if(!filteredSelectedKeys.Contains(selectedKey))
            Grid.Selection.UnselectRowByKey(selectedKey);
}
