Configuration

To configure the Kendo UI ListView for JSP editing, follow the steps below.

Step 1 Define the item template.

Example
    <script type="text/x-kendo-tmpl" id="template">
        <div class="product-view">
            <dl>
                <dt>Product Name</dt>
                <dd>#=productName#</dd>
                <dt>Unit Price</dt>
                <dd>#=kendo.toString(unitPrice, "c")#</dd>
                <dt>Units In Stock</dt>
                <dd>#=unitsInStock#</dd>
                <dt>Discontinued</dt>
                <dd>#=discontinued#</dd>
            </dl>
            <div class="edit-buttons">
                <a class="k-button k-button-icontext k-edit-button" href="\\#"><span class="k-icon k-edit"></span>Edit</a>
                <a class="k-button k-button-icontext k-delete-button" href="\\#"><span class="k-icon k-delete"></span>Delete</a>
            </div>
        </div>
    </script>

Important

Click events for elements with the k-edit-button and k-delete-button class names are automatically handled and treated by the Kendo UI ListView as edit and delete actions.

Step 2 Define the edit template.

Example
    <script type="text/x-kendo-tmpl" id="editTemplate">
        <div class="product-view">
            <dl>
                <dt>Product Name</dt>
                <dd>
                    <input type="text" data-bind="value:productName" name="productName" required="required" validationMessage="required" />
                    <span data-for="productName" class="k-invalid-msg"></span>
                </dd>
                <dt>Unit Price</dt>
                <dd>
                    <input type="text" data-bind="value:unitPrice" data-role="numerictextbox" data-type="number" name="unitPrice" required="required" min="1" validationMessage="required" />
                    <span data-for="unitPrice" class="k-invalid-msg"></span>
                </dd>
                <dt>Units In Stock</dt>
                <dd>
                    <input type="text" data-bind="value:unitsInStock" data-role="numerictextbox" name="unitsInStock" required="required" data-type="number" min="0" validationMessage="required" />
                    <span data-for="unitsInStock" class="k-invalid-msg"></span>
                </dd>
                <dt>Discontinued</dt>
                <dd><input type="checkbox" name="discontinued" data-bind="checked:discontinued"></dd>
            </dl>
            <div class="edit-buttons">
                <a class="k-button k-button-icontext k-update-button" href="\\#"><span class="k-icon k-update"></span>Save</a>
                <a class="k-button k-button-icontext k-cancel-button" href="\\#"><span class="k-icon k-cancel"></span>Cancel</a>
            </div>
        </div>
    </script>

Important

Click events for elements with the k-update-button and k-cancel-button class names are automatically handled and treated by the Kendo UI ListView as save and cancel actions.

Step 3 Define the interface for creating new items.

Example
    <div class="k-toolbar k-grid-toolbar">
        <a class="k-button k-button-icontext k-add-button" href="#">
            <span class="k-icon k-add"></span>Add new record
        </a>
    </div>

    <script>
        $(function() {
            var listView = $("#listView").data("kendoListView");
            $(".k-add-button").click(function(e) {
                listView.add();
                e.preventDefault();
            });
        });
    </script>

Step 4 Specify the parameterMap and the action methods which will handle the Create, Update and Destroy operations.

Example
    <kendo:listView name="listView" template="template" pageable="true"
        editTemplate="editTemplate">
        <kendo:dataSource pageSize="4" serverPaging="true">
            <kendo:dataSource-transport>
                <kendo:dataSource-transport-create url="${createUrl}" dataType="json" type="POST" contentType="application/json" />
                    <kendo:dataSource-transport-read url="${readUrl}" dataType="json" type="POST" contentType="application/json"/>
                    <kendo:dataSource-transport-update url="${updateUrl}" dataType="json" type="POST" contentType="application/json" />
                    <kendo:dataSource-transport-destroy url="${destroyUrl}" dataType="json" type="POST" contentType="application/json" />
                    <kendo:dataSource-transport-parameterMap>
                        <script>
                            function parameterMap(options,type) {
                                return JSON.stringify(options);
                            }
                        </script>
                    </kendo:dataSource-transport-parameterMap>
            </kendo:dataSource-transport>
            <kendo:dataSource-schema data="data" total="total">
            </kendo:dataSource-schema>
        </kendo:dataSource>
    </kendo:listView>

Step 5 Specify the properties of the model as well as the unique identifier (primary key).

Example
    <kendo:listView name="listView" template="template" pageable="true"
        editTemplate="editTemplate">
        <kendo:dataSource pageSize="4" serverPaging="true">
            <kendo:dataSource-transport>
                <kendo:dataSource-transport-create url="${createUrl}" dataType="json" type="POST" contentType="application/json" />
                    <kendo:dataSource-transport-read url="${readUrl}" dataType="json" type="POST" contentType="application/json"/>
                    <kendo:dataSource-transport-update url="${updateUrl}" dataType="json" type="POST" contentType="application/json" />
                    <kendo:dataSource-transport-destroy url="${destroyUrl}" dataType="json" type="POST" contentType="application/json" />
            </kendo:dataSource-transport>
            <kendo:dataSource-schema data="data" total="total">
                <kendo:dataSource-schema-model id="productId">
                    <kendo:dataSource-schema-model-fields>
                        <kendo:dataSource-schema-model-field name="productId"
                            editable="false" nullable="true">
                        </kendo:dataSource-schema-model-field>
                        <kendo:dataSource-schema-model-field name="productName">
                        </kendo:dataSource-schema-model-field>
                        <kendo:dataSource-schema-model-field name="unitPrice" type="number">
                        </kendo:dataSource-schema-model-field>
                        <kendo:dataSource-schema-model-field name="discontinued"
                            type="boolean">
                        </kendo:dataSource-schema-model-field>
                        <kendo:dataSource-schema-model-field name="unitsInStock"
                            type="number">
                        </kendo:dataSource-schema-model-field>
                    </kendo:dataSource-schema-model-fields>
                </kendo:dataSource-schema-model>
            </kendo:dataSource-schema>
        </kendo:dataSource>
    </kendo:listView>

Step 6 Implement the Read action method.

Example
    @Autowired
    private ProductDao product;

    @RequestMapping(value = "/editing/read", method = RequestMethod.POST)
    public @ResponseBody DataSourceResult read(@RequestBody DataSourceRequest request) {

        return product.getList(request);
    }

Step 7 Implement the Create action method.

Example
    @SuppressWarnings("serial")
    @RequestMapping(value = "/editing/create", method = RequestMethod.POST)
    public @ResponseBody Map<String,Object> create(@RequestBody Map<String, Object> model) {
        final Product target = new Product();

        target.setProductName((String)model.get("productName"));
        target.setUnitPrice(Double.parseDouble(model.get("unitPrice").toString()));
        target.setUnitsInStock((int)model.get("unitsInStock"));
        target.setDiscontinued((boolean)model.get("discontinued"));

        product.saveOrUpdate(target);

        return new HashMap<String, Object>() \{\{
            put("data", target);
        }};
    }

Step 8 Implement the Update action method.

Example
    @RequestMapping(value = "/editing/update", method = RequestMethod.POST)
    public @ResponseBody Product update(@RequestBody Map<String, Object> model) {
        Product target = new Product();

        target.setProductId((int)model.get("productId"));
        target.setProductName((String)model.get("productName"));
        target.setUnitPrice(Double.parseDouble(model.get("unitPrice").toString()));
        target.setUnitsInStock((int)model.get("unitsInStock"));
        target.setDiscontinued((boolean)model.get("discontinued"));

        product.saveOrUpdate(target);

        return target;
    }

Step 9 Implement the Destroy action method.

Example
    @RequestMapping(value = "/editing/destroy", method = RequestMethod.POST)
    public @ResponseBody Product destroy(@RequestBody Map<String, Object> model) {
        Product target = new Product();

        target.setProductId((int)model.get("productId"));

        product.delete(target);

        return target;
    }
