Editing

29 May 201918 minutes to read

The Kanban control has support for dynamic insertion, updating and deletion of cards.

Set allowEditing and allowAdding property as true to enable editing/inserting respectively. The primary key for the data source should be defined in primaryKey, for editing to work properly.

You can start the edit action by double clicking the particular card. Similarly, you can add new card to Kanban either by double clicking the particular cell or on an external button which is bound to call addCard method of Kanban.

Deletion of the card is possible by using deleteCard by passing primary key as attribute.

NOTE

In Kanban, the primary key column will be automatically set to read only while editing the card which is to avoid duplicate entry in the cards.

Configuring Edit Items

You need to configure the list of data source fields that are allowable in editing state using editItems property. The field property of editItems needs to be mapped with data source fields.

You can map the data source field as title to edit form using title property of fields. By default, it’s mapped with primaryKey.

The following code example describes the above behavior.

    Configuring edit items in JSP kanban control

    Edit modes

    Dialog

    Set editMode as dialog to edit data using a dialog box, which displays the fields associated with the data card being edited. Default value is dialog.

    NOTE

    For editMode property you can assign either string value (“dialog”) or enum value (ej.Kanban.EditMode.Dialog).

    The following code example describes the above behavior.

    Dialog in JSP kanban control

    Dialog Template Form

    You can edit any of the fields pertaining to a single card of data and apply it to a template so that the same format is applied to all the other cards that you may edit later.

    Using this template support, you can edit the fields that are not bound to editItems.

    To edit the cards using Dialog template form, set editMode as dialogtemplate and specify the template id to dialogTemplate property of editSettings.

    NOTE

    1. value attribute is used to bind the corresponding field value while editing.
    2. name attribute is used to get the changed field values while save the edited card.
    3. For editMode property you can assign either string value (“dialogtemplate”) or enum value (ej.Kanban.EditMode.DialogTemplate).

    Column Validation

    We can validate the value of the added or edited card cell before saving.

    The below validation script files are needed when editing is enabled with validation.

    1. jquery.validate.min.js
    2. jquery.validate.unobtrusive.min.js

    NOTE

    If you enabled the unobtrusive option, then need to refer the jquery.validate.unobtrusive.min.js
    file in your application along with the other script.

    jQuery Validation

    You can set validation rules using validationRules property of columns. The following are jQuery validation methods.

    List of jQuery validation methods

    Rules Description
    required Requires an element.
    remote Requests a resource to check the element for validity.
    minlength Requires the element to be of given minimum length.
    maxlength Requires the element to be of given maximum length.
    rangelength Requires the element to be in given value range.
    min The element requires a given minimum.
    max The element requires a given maximum.
    range Requires the element to be in a given value range.
