### Description

Add the option to constrain the RowSpan and ColSpan of individual tiles in the TileLayout.

### Specification (if feature)

Add options to the tiles such as MinColSpan, MaxColSpan, MinRowSpan, and MaxRowSpan.

Currently, only `RowSpan` `ColSpan` and `HeaderText` parameters cause a `TileLayout` to rerender when changed.  I use `Class` changes for a lot of styling (in particular it's useful for hiding/showing a `TileLayoutItem` without losing its position in the layout) and have to manually detect and call `StateHasChanged()` when the `Class` parameter changes on `TileLayoutItem`.

Please allow dynamic change of the TileLayoutItem Class property.

Hi,

We would like to request a feature wherein we can drag the tile on empty spaces and triggers the reordering of tiles. To make it some kind of docking feature on the TileLayout.

So far the workaround we see to put the tiles on those empty spaces is when you drag the tile in between tiles (between conversion rate and page views tiles) and if you drag it again on the same row it will reorder fine. Another one is to drag the tile on another tile (drag into most viewed pages tile) it will reorder the dragged tile on that empty space beside the existing tile.

Here's a sample of what we did:

Hi,

Is there a way we could drag the tile on those empty spaces in the tile layout? I've tried the samples in your page and it seems reorderable only reorders the tiles. Is it possible to put an option that we might be able to drag those tiles to the empty spaces instead of dragging them to another tile to switch places? See attached file as reference on what I meant.

In TelerikTileLayout the TileLayoutItem have the possibility to have have a HeaderText or even a HeaderTemplate, and behave as a TelerikCard, only without a footer.

Having the possibility to have a FooterTemplate would grant a better managment of the layout.

I am using a couple buttons in the HeaderTemplate of the tiles. It looks like their click events are sometimes not honored due to a mix up with the draggable event of the tiles when they are reorderable. Please prevent the component from stopping the click event in the tile header.

As a workaround for the time being, you can stop the propagation of the container wrapping the clickable elements:

<!-- suppress-error allows the script tag to be in a Razor file -->
<script suppress-error="BL9992">
  window.stopPropagation = (e) => {
    e.stopPropagation();
  }
</script>

<TelerikTileLayout Columns="3"
                   RowHeight="150px"
                   Resizable="true"
                   Reorderable="true">
    <TileLayoutItems>
        @{
            foreach (var tile in Tiles)
            {
                <TileLayoutItem @key="@tile">
                    <HeaderTemplate>
                        <div class="d-flex flex-col w-100 justify-content-between">
                            <div class="d-flex flex-row w-75">
                                <div class="p-2"><strong>@tile.Title</strong></div>

                            <div onpointerdown="stopPropagation(event)"
                                 class="d-flex flex-row w-25 justify-content-end">

                            </div>
                        </div>
                    </HeaderTemplate>

Event log: <TelerikButton Icon="clear" OnClick="@ClearLog">Clear Log</TelerikButton>

    void ClearLog()

    protected override void OnInitialized()

I am trying to resize a TextBox inside of a TileLayoutItem on resize of the tile. I have the resize handler implemented, and is accurately firing. However, I am not seeing the ColSpan actually change on the item, which would give me a point of reference to resize the textbox.

void OnResizeHandler(TileLayoutResizeEventArgs args)
    {
        if (args.Id == "commentTile")
        {
            if (CommentLI.ColSpan==1)
            {
                CommentWidth = "270px";
            }
            else
            {
                CommentWidth = (270 + (300 * (CommentLI.ColSpan - 1))).ToString() + "px";
            }
        }
    }

When using my own buttons in the header template, and I have Reorderable=true, the tile layout consumes mouse events and clicks on my buttons don't always work. I would like to have the tile layout provide command buttons that can work in this scenario that let me handle their clicks reliably.

The functionality I am after is closing an minimizing tiles, so built-in actions for that like with the window would be nice. Perhaps tile items could get a Visible parameter like the grid columns and that could also go in their state.

Here is the scenario I would like to implement:

User has a default dashboard, with Customise functionality which would:

• Allow the user to move and resize items (same as now)
• Add / remove item, adding using a drag and drop function from a set of tile types, for example exposed in a TelerikList component. Removing an item with a "delete" button or similar.
• Customise tiles, for example a time period on a chart.
• Save the state of the dashboard.

For loading and saving the dashboard with each tile having a specific content the easiest way I can see would be to bind the TelerikTileLayout to a data source:

<TelerikTileLayout Data="@TileData">

<TileConfiguration></TileConfiguration>

</TelerikTileLayout>

The data would be updated as and when the user configures their dashboard. 

For dragging and dropping new tiles a set of events would be necessary, both on the source tile list, e.g. OnDragBegin and on the tile layout OnDrop.
