### 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.

https://demos.telerik.com/blazor-ui/tilelayout/overview

Here's a sample of what we did:

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

                                       OnClick="@(()=>EditTile(tile))">
                                </TelerikButton>

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

@if (EventLog != null)
{
    <ul>
        @foreach (string log in EventLog)
        {
            <li>
                @log

    async void EditTile(TileData tile)

        EventLog.Add("Edit fired for " + tile.Title);        
    }

    async void DeleteTile(TileData tile)

            new TileData { Title = "Tile 6", Content = "6 - Lorem Ipsum" },

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";
            }
        }
    }

Hey all, I just tried the big upgrade (VS 2020, .Net 6). During it, I moved from Telerik UI for Blazor 2.30. I've invested a lot of time into using this component and it came out as a non-starter in this release. After digging for a couple hours, I just kept it simple (see code). 

Any time you put an @ inside a TileLayoutItem, it breaks - just freezes everything. So I can't tell you where it is coming from, but I can tell you it doesn't work. To reproduce, see the following code, but basically use "@someObject" as the value of an attribute of TileLayoutItem or inside Content/HeaderTemplate.

My use case is more complicated and I'm waiting for a mid-December pre-release (see ticket 1543513), but here's a way to reproduce (I hope)

Example: 

<TelerikTileLayout Reorderable="true"
                   Resizable="true"
                   >
    <TileLayoutItems>
        @foreach (string name in Names)
        {            
            <TileLayoutItem Class="builder">
                <Content>@name</Content>
            </TileLayoutItem>
        }
    </TileLayoutItems>
</TelerikTileLayout>

@code {
	public List<string> Names { get; set; } = new List<string> { "Sara", "Dan", "Frank", "Deuce" };
}

I want to dynamically change the TileLayout Reorderable parameter but the component does not react to that change. Dynamic change in the Resizable parameter is also not applied.

I am also trying to change the TileLayoutItem ColSpan dynamically - for example, when implementing it in a responsive layout (https://docs.telerik.com/blazor-ui/knowledge-base/tilelayout-responsive) but using a variable as the ColSpan value does nothing. The TileLayout does not react to a change in the ColSpan parameter either.

It would be nice if the TelerikTileLayout could be told to refresh itself or to refresh after some of its parameters is changed.

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.
