How to override values in GridHandle from library?

lexthang

This is the setup: I have a grid element in a library. The grid has 1 rows with 3 cells, one of which contains a label.

At runtime I want to put this grid item on a newly created report and then set the label to my own text. I could put the grid on the new report this way:

GridHandle newGrid = elementFactory.newGridItem("MyGrid");
GridHandle gridHandle = (GridHandle)libHandle.findElement("SectionHeaderCurvedEdgeGrid");
newGrid.setExtends(gridHandle);
cellHandle.getContent().add(newGrid);

However there's no way I can get the proper LabelHandle to set my custom text. The newGrid object has no row and no column (although if I write the report out to a file and check it in the designer, I do see that it is indeed linked from the library, and there are 3 cells in a row.

How do I change the text of that label?

Thanks!
