[HxGrid] How to add more than 1 custom column?

[surgicalcoder]

I'm trying to create more than 1 custom column on a Grid, the use case is to hold buttons or other controls,

HxGridColumn does not contain any ChildContent, only a HeaderTemplate and a PlaceholderTemplate

HxContextMenuGridColumn<T> seems to do the job, however you can only add one those on the grid, because of this line here, and because it's effectively hard coded in HxContextMenuGridColumn, you can't add more than one custom column,

Can this get changed to accept a parameter, so you can have more than one, or perhaps copy the same logic from HxGridColumn ?

My current work around is to have a class that has:

public class HxGridCustomColumn<TItem> : HxContextMenuGridColumn<TItem>
{
    protected override string GetId() => Guid.NewGuid().ToString("N");
}

Feels like this should be part of the main lib itself.

I may have misunderstood your issue, but I use:

[Parameter] public RenderFragment<TItem> ItemTemplate { get; set; }

on HxGridColumn to include whatever I want in a column, buttons, custom html etc.

Is this what you need?

[surgicalcoder]

@pollardpj Very possibly, genuinely not sure how I missed that 😆

What does HxContextMenuGridColumn give you that HxGridColumn doesn't? Or is that the reason it might be removed in vNext?

In that case, maybe the documentation needs an example, I didn't find it obvious hence why I went down the Context Menu route...

Give it a go, if you still have issues, I may have faced them myself, so let me know here: I find that the Havit Library is very flexible, always has the solution to a problem I have. I had looked at HxContextMenuGridColumn<TItem> for my projects, which is useful, but settled on ItemTemplate as it gave me what I specifically wanted.

You are right, the HxContextMenuGridColumn is a very simple preconfiguration of HxGridColumnBase and does not bring much value over HxGridColumn except for better readability.

(What we will probably remove is the HxGrid.ContextMenu parameter (RenderFragment) which was originally inteded to be used for context menus but turned out to be difficult to customize. Thus we decided for HxContextMenuGridColumn or HxGridColumn itself to be more flexible.)
