Validate a single cell in datatable

Webix JS
1

I’m trying to validate a single cell in my datatable. The basics of my implementation looks like this:

onAfterEditStop:function(state, editor) {
if (this.validate(editor.row)) {
// validated
}
}

This code validates all the cells in a row but I would like it to only validate the cell that was edited. Can someone explain to me how to accomplish this?

Thanks

Hello nate,

The validate() method for data components is implemented in the following way:

  • no argument - the whole component data is validated;
  • item ID as an argument - the whole item data is validated (here: datatable row with the given ID).

So if there’s invalid data in any cell of a datatable row, it will be highlighted as invalid and the cell with invalid data will be additionally marked.

To to achieve per-cell validation and marking you should provide custom logic, like this: http://webix.com/snippet/12b86744

(Cell styling can be studied on this sample: http://docs.webix.com/samples/15_datatable/21_styling/03_cell_styling.html)

Or, alternatively, you can make use of methods described in the following samples:
