Hello KendoUI Team,
One issue we've encountered that we were hoping you could shed some light on is the behavior that occurs when copy/pasting cells with attached validation, similar to the issue seen with disabled cells here: http://www.telerik.com/forums/copy-paste-of-disabled-cells .
We have our spreadsheet set so that we define the validation for each of the spreadsheet's columns. However we've noticed that when a user copy/pastes between cells of different columns, it also copies the validation over which is less than ideal for what we are trying to accomplish.
You can replicate the behavior I'm seeing on the kendo demo page: https://demos.telerik.com/kendo-ui/spreadsheet/validation
-> on the demo page, copy cell B7 (christina.toms) into an empty cell like H7 or a cell with existing validation like D7. You will notice that the red flag as well as the cell's associated data validation is copied as well and will end up overriding any of the other cell's initial validation rules. Any suggestions so that we can work around this and have it copy only the cell value?
