    I have been using the radgrid with the indicator demonstrated in this blog post (I use this type of cell 3 times in a row) the client then changed their expectations and wanted the tree style features of the treelistview so I adapted the column and it all works fine apart from the performance.  If i have have 1 or 2 items in the child collection the tree expends with no issues but if i have 20 or 30 in the child collection my CPU hits 50% and takes about a minute to expand or collapse

    Any suggestions?

    Hi Paul ,

    The animated cell demonstrated in the blog post is indeed a heavy element ( as it performs animations on load ) .

    I am sure we can make some optimizations for your specific scenario. For this I will need to step through your code .

    Can you please open a support ticket and attach me the project ( or a simplified version of it )  , I will be glad to do a  profiling session and  change what is needed to boost the performance .
