Hi, I am getting the exception while performing drag drop on multiband grid. I am dragging a row on to the other row and deleting the dragged row. I am attaching the sample project which has the issue. In the sample just drag "Employee 3" over to "Employee 1" you will get the exception. Can some one pls help?
Hi,
The error message you are getting here is coming from the BindingManager. Basically, your data source is rejecting the deletion - it's nothing to do with the grid.
It's probably because your data source and the Children property are using List<T> instead of BindingList<T>. List<T> is very limited as a data source.
Thanks Mike. That did the trick. But I have a follow up questions. I am having the data in the following manner:-Band 0 (Profit) | Column Total
Band 1(Services) | Column Total
Band 2(Software) | Column Total Band 2(Hardware) | Column TotalI want the Sum of Total Column of Band 2 to be the Total of Band 1. And the total of Band 1 to be the total of Band 0. Provided that I have recursive Data structure so I dont have any control on number of bands (the depth will not be more than 8). Will it be possible in the grid using Formulas or WinCalcManager? If yes, Can you pls provide a sample or a link for me to get started ? Thanks
