Hi,

Before updating to the latest runtime last week, the following code used to work - the main thing that used to happen is that when .Delete() was called on an item within a TypedList, it used to be removed from the TypedList container - but now this doesn't seem happen?

Both were under 2.6, I'm not sure of the previous runtime, but it would have been from around September last year.

Current Version: LLBLGen 2.6 Designer (Oct 6, 2008 ) Runtime versions: SD.LLBLGen.Pro.ORMSupportClasses.NET20.dll : 2.6.9.313 SD.LLBLGen.Pro.DQE.SybaseAse.NET20.dll : 2.6.8.819

Basically I iterate through the returned typedlist and creating a counter list, then removing any "duplicates" using the .Delete().

I then go through the smaller list again, updating the writable LouthDayCount property, which gets displayed with the other info. in the grid.

Code below:

ScheduleResourceTypedList myScheduleResourcesList = dsSchedule.TypedList as ScheduleResourceTypedList;

// list of Louth keys + instance counter
Dictionary<string, int> myLouthKeyList = new Dictionary<string, int>();
for (int iIdx = myScheduleResourcesList.Count-1; iIdx >= 0; iIdx--) {
    ScheduleResourceRow thisRow = myScheduleResourcesList[iIdx] as ScheduleResourceRow;
    string sThisLouthId = String.Format(SummaryKeyFormat, thisRow.ScheduleDate, thisRow.LouthId);
    if (myLouthKeyList.ContainsKey(sThisLouthId)) {
        myLouthKeyList[sThisLouthId] += 1;
        thisRow.Delete(); // RELEVANT LINE!
    } else {
        myLouthKeyList.Add(sThisLouthId, 1);
    }
}

// iterate through the summary rows, updating the Louth count value
foreach (ScheduleResourceRow thisRow in myScheduleResourcesList) {
    thisRow.LouthDayCount = myLouthKeyList[String.Format(SummaryKeyFormat, thisRow.ScheduleDate, thisRow.LouthId)];
}

Any ideas?

• Please update to the latest runtime library version.
• Are you sure the debugger is entering into this if?

if (myLouthKeyList.ContainsKey(sThisLouthId)) {

• I assume the problem is that the typedList row isn't removed from the typelist, right?

Hi - thanks for the response.

Willdo, it takes me a little time to do this because I have to use an a slightly altered ormsupportclasses due to our use of Sybase ASE..

I have a meeting now, hopefully will be out of it in 2 hours + do this + let you know.

Yep, it is sure is

Exactly! I should have mentioned the error before sorry, a DeletedRowInaccessible Exception gets raised during...

foreach (ScheduleResourceRow thisRow in myScheduleResourcesList) {
    thisRow.LouthDayCount = myLouthCountList[String.Format(SummaryKeyFormat, thisRow.ScheduleDate, thisRow.LouthId)];
}

... when I try to read the thisRow.ScheduleDate property, because this particular row was "deleted" (...but its still in my typed list collection... which is my issue)

Wow a quick meeting, may the rest of my day be this lucky

I've updated to latest the ORMSupportTools assembly + recompiled, now at version 2.6.9.327, and the issue is still the same.

btw. I checked on my Production WebServer i.e. where it seems to work ok and the runtime assembly was 2.6.8.819 if this helps.

Please delete the row from the DefaultView of the typedList using its index;

mytypedList.DefaultView.Delete(rowIndex);

And to test it you can check on the Count of the DefaultView before and after the deletion.

Hi Walaa

Thanks, but that made no difference

i.e. i changed

thisRow.Delete();

to

myScheduleResourcesList.DefaultView.Delete(iIdx);

..and the myScheduleResourcesList.Count didn't decrease?

Ok this one seems to work

myScheduleResourcesList.Rows.Remove(thisRow);
