isocum asked on 23 Mar 2010, 03:09 PM

i am using a radgrid with 3 level hierarchy. it was working perfectly until a few days ago, but it simply doesn't work now. the hierarchy index should come either as a single digit n or n_m format, but in client and server load modes, i always get 0, regardless of level. serverOnDemand mode returns either 0 or 0_0. thus i can't bind the proper data in the nested grids. can anyone help?

here is aspx and codebehind:

Hello,

I created a sample project based on the code you posted below. Unfortunately I'm unable to reproduce this problem. Please download the demo and let me know whether it exhibits the same behavior on your end.

Thanks Daniel, e.DetailTableView.ParentItem.ItemIndexHierarchical returns a string like "linenumber:0_sublinenumber", which solves the problem. I still have no idea why the previous code stopped working though.
