WebHierarchicalDataGrid error on PostBack when editing
posted

I attached a sample project, without the ig_res folder. I am using version 10.2. To reproduce the issue, you can edit a value in the grid and click the "Test" button.

The original problem we needed to solve was to display sums of values (subtotals) for several rows in the grid. That's why we started using the WebHierarchicalDataGrid (WHDG). We managed to display the sum of cell values from the rows in the child band in the parent row when initially loading the grid, but when trying to edit values and post back, we get exceptions like the one below. The message "Property Year1Cost not found" probably refers to the name of the property Year1Cost in the object GroupedComponent, list of which we bind to the grid. Please let us know if using WHDG is the right way to get subtotals. If it is the right way, can you let us know how to use the grid properly so as to avoid the exception and be able to edit and save the values from the grid. Thank you.

    Hi - I am having a similar problem - getting Property XXX not found... Did you ever determine cause, get a resolution for this? Thanks. Charlie
