Add child grid to GridControl

Is there a way that I can add a sub-grid or child grid to a GridControl row? In our case, I have rows of files that the application processes. Each row has one of the cells that serves as a ProgressBar. The progress bar shows the progress of each task performed (validate template, validate data and import) on each file. When errors come back, I''d like to programmatically show a sub-grid (with a plus sign by the parent row) with a list of errors. If it cannot be done with a GridControl, please let me know which control to use and an example of a dynamic way to add a child grid. Thank you for any help that you can give to us, Elsa

Hi Elsa, You can add a plus sign button and show a drop down grid with the error list at a particular row through code. This can be achieved by using a custom cell type. I have attached a sample in which, the GridListControl is used as the drop down grid to show the error list. Let us know if you are looking for something different. Also take a look at the VirtTreeGrid sample in \Syncfusion\Essential Studio\4.1.0.51\windows\Grid.Windows\Samples\In Depth\VirtTreeGrid\ Regards, Calvin.
