How add/remove item dynamic in Tilelayout ~

[duy]

Hi !

 

I'm using Kendo TileLayout in Jquery. When I create Tilelayout.

 

I want add or remove item dynamic at runtime, but I don't find way to do it.

 

Please help me do it

 

Many thanks !

If we can not add/remove, is there a why we can hide/show a container?

Hello Duy,

I could suggest finding the desired element with jQuery and setting its display CSS property to "none", for example:

$("#tilelayout").find(".k-tilelayout-item:first-child").css("display", "none");

You can check the following Dojo I have prepared demonstrating the above:

Let me know if you have any questions.

Nikolay, 

you can find first and last child and turn display on/off, how do I find a child using index like child 3 or child 4?

thanks.

 

$("#tilelayout").find(".k-tilelayout-item:first-child").css("display", "none");

 $("#tilelayout").find(".k-tilelayout-item:last-child").css("display", "none");

Hi Duy,

The items can be located via id and respectively set hidden with jQuery:

var item = $("#tilelayout").find("#" +$("#tilelayout").getKendoTileLayout().items[1].id) //1 is the id of the container
$(item).css("display", "none");

Please check the following Dojo out:

Hi,

I've been able to achieve a solution that removes and adds an item in the layout. This, however, is not perfect. When you do this, the HTML inside each container will be re-rendered, which is not always ideal. Depending on your situation, this may suffice. Adding a container works in a similar. When adding a new tile container, you need to do is append another Tile Container definition to the "items" array, and then call setOptions.

removeContainer(itemId) {
        var items = this.layout.items;
        var itemToRemove = this.layout.itemsMap[itemId];

        items.splice(items.indexOf(itemToRemove), 1);
        this.layout.setOptions({ containers: items });
    }

addContainer(widthInColumns, heightInRows, headerText, bodyHtml) {
        var items = this.layout.items;

        items.push({
            colSpan: widthInColumns,
            rowSpan: heightInRows,
            header: {
                text: headerText
            },
            bodyTemplate: bodyHtml
        });
        this.layout.setOptions({ containers: items });
    }

Hi Timothy,

Indeed, adding and removing tiles depends on the setOptions() method which re-renders the whole TileLayout. For the time being this is how the widget works.

Is there a workaround or a solution to this? The tileLayout option is completely useless if the contents are emptied every time the setOptions is called.

Hi, Lee,

I've shared an approach that you can try, in the private ticket. I'm sharing the Dojo here as well:
