Hi Team,

I wanted to use the GridViewMultiColumnComboBoxColumn in my grid and bind it to data set which contain medium amount of data. The memory consumption is way more that I expected also it is taking alot more time to display the drop down. I switch to MultiColumnComboBox using template and it is working way better and can not see memory spikes.

Can you please help me on this. I am currently using Telerik version "2020.1.218"

Hello Usman,

Using the GridViewMultiColumnComboBoxColumn comes with the cost of a bit more complex binding evaluation logic. The approach with a normal GridViewDataColumn with a Cell/CellEditTemplate should bring a better performance in this case. However, can you provide more information on the case?  How many rows and columns you have? How many of them shows a GridViewMultiColumnComboBoxColumn? Can you show the RadGridView setup defined on your side?
