So I have used a grid with batch edit (in cell) for editing offer positions. The offers are quiet big and usually have between 20 and 500 positions.The performance is now really bad and this is almost not usable...
The reason are quiet simple the DOM is getting to big. The simple solution would of course be to implement paging. But the customer needs to see all positions and can even move the positions with drag & drop. It feels kinda too late to change it to paging. It would be a step backwards.
With some tests I have found out that mostly the EditorTemplates are mostly the issue. I use here quiet complex controlls.
Do you have any ideas how to easily improve the performance? Is it maybe possible to render the EditorTemplate during runtime if a cell is clicked?
Here the code for the grid, it is dynamic with some definition classes:
