Hello friends.
Struggling here. Can you help?
I'm using DevEx's ASP.NET ASPxGridView control with one parent grid and two child grids. I'd like to retrieve related records in the children grids when I expand the parent grid row. Can't figure out how to proceed.
I'd like to set the SelectParameter (and hence e.Filter) on the Child grid LLBLGenProDataSource2 component to the key value of the Parent grid Master row that is being expanded, but I don't know how to properly select the PropertyName, etc. in the Parameter Collection Editor.
LiverPersistence is FALSE on both parent and child data sources.
Any help is appreciated! Thanks.
Jeff

Would you please post more info as stated here: http://www.llblgen.com/TinyForum/Messages.aspx?ThreadID=7720
Like the runtime library version for instance.
Also it would be much helpful if you attach the aspx file of your web form.

I'm using the latest version of the LLBLGenPro runtime. Using adapter architecture.
Well, there's really not much here to show, since I'm talking about a conceptual issue. But, here you go:

Basically, three LLBLGenProDataSource2 components. One parent and two children. Want to EXPAND the parent row and trigger the PerformSelect events on the children components. But I have NO idea how to pass the Parent.MasterRowKeyValue to the SelectParameters of the children data sources.
Thanks for your help.

Hook the event on the server, here are some snippets from one of my apps:
OnBeforePerformDataSelect="uiDetailGrid_DataSelect"
protected void uiDetailGrid_DataSelect(object sender, EventArgs e)
{
ASPxGridView detailGrid = (ASPxGridView)sender;
int registrantID = (int)detailGrid.GetMasterRowKeyValue();
registrationDS.FilterToUse = manager.GetRegistrationFilter(registrantID);
}
GetRegistrationFilter() returns a RelationPredicateBucket, obviously. Does this help?

Thanks Jim. Can you post the code to GetRegistrationFilter? I don't recognize it. - Jeff
