“Folder Tree” cannot retrieve data correctly.

[Ifdev02]

 “Folder Tree” mode.
Private Sub Grid_CellBeginEdit(ByVal sender As Object, ByVal e As GridViewCellCancelEventArgs)
programName = DirectCast(Grid.Rows(e.RowIndex).Cells("program").Value, String)

with code in your example, i could not get the correct cell value because e.rowindex somehow is the wrong row... due to rearranging in tree mode...

It took me few hours to find out that your e.rowindex is reference to the non-tree mode grid... so how can I get user interaction during the tree mode?

Also your support ticket page is 404 error.

Thanks,
J.

Hello Ifdev02,

I'm sorry to tell you this , but there are a series of bugs in Folder Tree, which will be addressed in the next release, until then it will, at best, be a series of patches over patches, please see this thread for more information.

Hope this helps, if you have any other questions or comments, please let me know,

Best Regards,

Hello Joe,

The RadGridView row indices are recreated when its mode is changed from flat grid to grouped, hierarchical, sorted, etc. It improves the performance while iterating rows in these modes.

The code snippet you provide gives the cell a value of the "program" column which is in the same row with the cell you currently edit. It is equivalent to the code snippet below:

Private Sub Grid_CellBeginEdit(ByVal sender As Object, ByVal e As GridViewCellCancelEventArgs)
programName = DirectCast(Grid.CurrentRow.Cells("program").Value, String)

I would kindly ask you to give us more details about your scenario and explain why you receive data from a wrong row. This will allow me to assist you further.
