optionLabel as a normal option

[Pierre]

Hi !

I'd like to know if it's possible to display the optionLabel as the first option of the DropDownList. I need this functionality to be homogeenous with other select components.

I also would like to know if it's possible to manage the "required" attribute if I create an option by myself without using the "optionLabel".

 

Thanks for your help.

Hello,

I am not sure I understand your question very well. Basically, the optionLabel gets displayed as a first option by default. Also, the "required" validation rule works as expected when the optionLabel is selected. Would you please check this example and let me know if I am missing something?

Hello,

I have a similar need. I want all the values in the datasource to be presented without an optionLabel. I set default values on the create window. optionLabel's translate to null which I do not want to allow.

Hello Rick,

Can you share more details about your scenario and if possible - some code snippets?

I see in my code below that I am specifying an optionLabel text value.

I think that I want to have a default value and show its text.

Null is not permitted as a value here, and in other similar situations.j

Thanks,

Rick

$("#IssueType").kendoDropDownList({ dataSource: window.DataSource.IssueTypeDS,
    autoBind: true,
    dataTextField: "IssueTypeName",
    dataValueField: "IssueType",
    valuePrimitive: true,
    optionLabel: localize("format", "SelectType")
});

Hello Rick,

In case no option label is required, then I would recommend omitting the configuration option entirely: 

$("#IssueType").kendoDropDownList({ dataSource: window.DataSource.IssueTypeDS,
    autoBind: true,
    dataTextField: "IssueTypeName",
    dataValueField: "IssueType",
    valuePrimitive: true
});
