Adding validation to column with dropdownlist

[Jazzy Marie]

I have an ejs-grid with a booleanedit type column and a dropdownedit type column. How can I make the dropdown selection required only when the booleanedit column is checked?

Hi Jazzy,

  Greetings from Syncfusion support.

  Based on your query, you want to validate a column in the grid based on another column value. Your requirement can be achieved using the custom validation. We have already discussed the same in detail in the below documentation. Please refer the below documentation for more details.

I came across this explenation, but I couldt follow it. In particular the customFn method with the switchcase. Could you tell me what part of that code I need to adjust to make a booleantype column enable/disable the validation for another column.

Hi Jazzy,

Query: Adding validation to column with dropdownlist

We have analyzed your query about the adding validation to column with dropdownlist in the documentation. The window['role'] stores the value of the one column and using switch case we validate the values of other column. This validation method is added to the column through column.validationRules. We have attached the documentation link for your reference.
