How to add a custom tooltip description

[John]

How do you add a custom tooltip for specific columns in the grid?
For example, one my columns has the following grid schema setting:

item1Description: { editable: true, validation: { required: true }, defaultValue: '' }

 

When there is no value entered, the error message in the tooltip is "item1Description is required". How can I make it show a custom description like "Item 1 Description is required"?

I have seen this in the documentation. Is there somewhere in the documentation that states what all are the different options or settings we can override?

 

fields: {
    /* name of the field */ name: {
        type: "string", // the field is a string
        validation: { // validation rules
            required: true // the field is required
        },
        defaultValue: "<empty>" // default field value
    },

    /* name of the field */ price: {
        type: "number", // the field is a number
        validation: { // validation rules
            required: true, // the field is required
            min: 1 // the minimum value is 1
        },
        defaultValue: 99.99 // default field value
    },

    /* name of the field */ id: {
        editable: false, // this field is not editable
        nullable: true // a default value will not be assigned
    }
}

Hello John,

 

Please refer to the Grid / Custom validator editing demo that shows how to define custom validation rules and error message, which will be shown if the validation fails.
