I have noticed a column alignment issue when collapsing and then expanding rows in a TreeGrid. If a TreeGrid is expanded and then the user resizes a column manually, upon collapsing and re-expanding, the expanded cells within the column that was resized are drawn in their original position. If the user then attempts to resize the column again, the cells snap back to the correct position. This will continue to happen whenever a column is manually resized and then rows are collapsed and expanded.
I have attached an image to show this issue. The 2nd and 3rd rows under %MV are misaligned with the "%MV" column. If the user manually changes the width of the "%MV" column, the cells (100% values) will snap back to proper alignment. If the user collapses "Total" and then re-expands "Total", the cells will once again be misaligned.
The "%MV" column is using a GridCellRendere and the following properties are set for the grid.
Note: I remember seeing a similar issue with a standard grid when manually resizing columns. The grid contained nested column headers.
TreeGrid<ModelData> grid = new TreeGrid<ModelData>(_Store, cm);
