Programmatically select child record
posted

I'm using Version 9.2.20092.2049.

I have a hierarchical XamDataGrid with Parent and Child records (Hierarchy has only two levels).If I've select a record on the first level, I can set it active by

xamMyDataGrid.Records[ParentRecordIdx].IsActive = true;
xamMyDataGrid.BringRecordIntoView(xamMyDataGrid.Records[ParentRecordIdx]);

If I want to select a child record do it in a similar way by calling

xamMyDataGrid.Records[ParentRecordIdx].ViewableChildRecords[ChildRecordIdx].IsActive = true;
xamMyDataGrid.BringRecordIntoView( ....

But this time the record is not selected. The background color is not changed and the triangle on the left is missing.

Do child record need special treatment? What could be the cause of the problem?

Thanks in advance for all answers.

    Hello Markus,

    You hsould be able to active/select a record, using the following code:

    if (xamDataGrid1.ActiveRecord == null)

                {

                    xamDataGrid1.Records[0].IsActive=true;

                }

     

                DataRecord parentRecord = xamDataGrid1.ActiveRecord as DataRecord;

                ExpandableFieldRecord expandableRecord = parentRecord.HasChildren? parentRecord.ChildRecords[0] : null;

                if (expandableRecord != null)

                {

                    DataRecord firstChild = expandableRecord.ChildRecords[0] as DataRecord;

                    parentRecord.IsExpanded = true;

                    xamDataGrid1.ActiveRecord = firstChild;

                }

    However, I see an issue with this. When the child record is activated, the record selector is not active. This looks like an issue and a developer support engineer is already working on this.  I am attaching the sample project that I used for this.
