  Hi Team,

  We have an editable wijmo grid with 3000 rows and 25 columns, out of these 25 columns, 20 are dropdown field with 250 values in each list. Now when we try to sort the grid on these dropdown columns we face lag/freeze, and sometimes page crash issues.

  We do not face such issues when we reduce the number of rows to 300 in the grid OR 250 dropdown values to 20. But in real scenarios we need to show all data with all dropdowns without any lag/freeze OR page crash issues. Can you please help us resolve the above issue.

  Thank you!

  Hi Rasika,
  
  Please try to use DataMap instead of Cell Template if you are using CellTemplate to add DropDown since CellTemplate take more time to render the Cells than DataMap.

  Please refer to the following sample and observe the performance differenece between them.

  Please let us know if you have any further queries.

  Hi Manish, our issue got fixed by using the latest version of wijmo libraries.

  Thanks!
