Hi guys,

I have a LLBLGenProDatasource that is bound to a dropdownlist, and for the datasource i switched to design view and created two event handlers in VS2005. The idea is to create filters to limit the records returned to bind to my dropdownlist. Unfortunately, when i run the page i do not hit the breakpoints inside both event handlers. What could the issue be?

Here is the code:

protected void LLBLGenProDataSourceAdvertisers_PerformGetDbCount(object sender, PerformGetDbCountEventArgs e)
{
    IPredicateExpression filter = new PredicateExpression();
    if (filter.Count > 0)
    {
        filter.AddWithAnd(new FieldLikePredicate(AdvertiserFields.IsActive, "%" + 0 +  "%"));
    }
    else
    {
        filter.Add(new FieldLikePredicate(AdvertiserFields.IsActive, "%" + 0 + "%"));
    }
}

and

protected void LLBLGenProDataSourceAdvertisers_PerformSelect(object sender, PerformSelectEventArgs e)
{
    IPredicateExpression filter = new PredicateExpression();
    if (filter.Count > 0)
    {
        filter.AddWithAnd(new FieldLikePredicate(AdvertiserFields.IsActive, "%" + 0 + "%"));
    }
    else
    {
        filter.Add(new FieldLikePredicate(AdvertiserFields.IsActive, "%" + 0 + "%"));
    }
}

This is LLBLGenPro v2.5 using Selfservicing mode and .NET 2.0 on Win XP Pro SP2, and Visual Studio 2005 Team System SP1.

Thanks,

Hi Lloyd,

1. Make sure that yourLLBLGenProDataSource.LivePersistence = false
2. You have to make the fetch at your handlers. Please read this examples at the help: _LLBLGenPro Help -> Using the generated code -> SelfServicing -> Databinding at designtime and runtime -> Databinding with ASP.NET 2.0 -> Usage examples -> Example using Perform Event handlers. _ Tip: If you are only modifying the filter, you could do that outside the handlers (Page_Load, for instance), then you leave _LLBLProDataSource.LivePersistance = true _and don't need to handle those events.

Hi goose,

Thanks for the help...the problem had to do with Live Persistence. I will keep your advice in mind as i proceed.

Much respect,

Lloyd Dube
