Hi Team,
We have a dynamic radgrid with dynamic number of columns, which are created by binding a datatable to radgrid in code behind file. Also we have a horizontal scrollbar for moving column. Radgrid behaves ok when the auto generated column are less but when we have more than 50 column it start showing lagging in UI like horizontal scrollbar moves very slow and overall grid renders very slow on page load.
Please do let us know what can be causing this. also do let us know if you required more information.
