ability to specify datatype explicitly

[Aleksandr]

need to have the ability we have in a grid, to set the field to "string" or object EXPLICITLY 

 

P.S seems right now it is under self determination based on fields value & if the field is null & editor DropDown, the object will be set instead of just value

Hi, Aleksandr,

The data type of the fields can be set through the underlying dataSource schema configuration:

dataSource: {
                     schema: {
                        model: {
                            id: "ProductID",
                            fields: {
                                ProductID: { editable: false, nullable: true },
                                ProductName: { validation: { required: true } },
                                UnitPrice: { type: "number", validation: { required: true, min: 1} },
                                Discontinued: { type: "boolean" },
                                UnitsInStock: { type: "number", validation: { min: 0, required: true } }
                            }
                        }
                    }
}

Hello Georgi,

 

please confirm that it is possible, I am looking at the forms API doc & can't see a data source option:

https://docs.telerik.com/kendo-ui/api/javascript/ui/form?_ga=2.158395000.336107526.1673130214-1931469790.1620243254&_gl=1*1e1i6e3*_ga*MTkzMTQ2OTc5MC4xNjIwMjQzMjU0*_ga_9JSNBCSF54*MTY3MzUzNzg0MC44Ni4xLjE2NzM1Mzc4NTQuNDYuMC4w

Hi, Aleksandr,

My apologies about the misunderstanding on my end.

No, it isn't possible to explicitly set a "field" type in the Form component.

However, the described problem could be potentially resolved by configuring the valuePrimitive option of the DropDownList.

You can set it through the editorOptions of the Form field.

When valuePrimitive is set to true, the model will be updated with the value from the dataValueField. When it is set to false, the model is updated with the entire object.

Let me know if this works for you.

Best Regards,

Georgi

Hello Georgi,

thx a lot for your advice, value primitive should work. In addition, if my request could be taken as a future request, it would be great, seems just a few tweaks to the forms control could make it perfect & a little bit more manageable

Thx Alex

Hi, Alex,

We can certainly open a FR, however may I ask you to clarify a bit more about what the expected result is?

What should happen if you tell the form field.type = "string" when the default value in the formData is a number? Should it change the editor to a TextBox instead of NumericTextBox?

Best Regards,

Georgi

[Aleksandr]

exactly, the good example is a nullable bool (bool?), now if it is null you show a textbox instead of a checkbox, but if specify the type as a boolean, you will show the right control

Hi, Alex,

I've synced with the Devs regarding this functionality and it looks like it is already possible to do what the schema.model of the dataSource does.

Take a look at the following example:

    <form id="myForm"></form>

    <script>
      $("#myForm").kendoForm({
        formData: {
          ID: 1,
          Date: kendo.toString(new Date(), "MM/dd/yyyy"), // String date
          Number: "54" // String number
        },
        items: [{
          field: "Date",
          label: "Date:",
          editor: "date", // Set the editor to "date" like you would do in a dataSource schema model.
          validation: { required: true }
        }, {
          field: "Number",
          label: "Number:",
          editor: "number" // Set the editor to "number" like you would do in a dataSource schema model.
        }]
      });
    </script>

Georgi,

 

this is exactly i have asked for, seems the documentation needs to be updated, here completely diff chose for editors

 

Defines the editor widget type. Available options are:

• DropDown widgets - "AutoComplete", "DropDownList", "ComboBox", "MultiSelect", "DropDownTree", "MultiColumnComboBox"
• DatePicker widgets - "DateInput", "DatePicker", "DateTimePicker", "TimePicker"
• Input widgets - "TextBox", "TextArea", "NumericTextBox", "MaskedTextBox", "RadioGroup", "CheckBoxGroup", "Switch", "Rating", "Slider", "ColorPicker", "ColorGradient", "ColorPalette", "FlatColorPicker", "Signature", "hidden"
• Editor widget - "Editor"

Hi, Aleksandr,

I am glad the problem has been resolved!

I'll add a note about updating the API example with additional information.

Best Regards,

Georgi
