Hi that is what i looked for. i*ll give it a try :-)

btw is there an event i can use when a new record is added to the bound datasource?

I bound t he datagrid to an observeable collection. If theres an event which triggers when i add the item to the collection it would be perfect.

I tried the RecordAdded - Event but it isn't triggered.

Hi,

if you want to expand for example the groupBy record with index 3, you can do the following:

foreach (Record rec in xamDataGrid.Records)
{
    if (rec.RecordType == RecordType.GroupByField 
             || rec.RecordType == RecordType.GroupByFieldLayout)
    {
        GroupByRecord groupRecord = (GroupByRecord)rec;
        if (groupRecord.Index == 3)
            groupRecord.IsExpanded = true;
    }
}

ok thanks

is there a way to achieve this via xaml ?

and second question: how can i expand an specific groupbyheader ?

Ok, then try this in code-behind:

this.xamDataGrid.Records.ExpandAll(true);

Regards

Hi

I don't want the GroupbyArea getting expended. I want the generated groups (at least some of them ) itself expanded.
