## MgGridDataColumn

Extended `DxGridDataColumn` with InfoPanel and URL link support.

| Parameter | Type | Default | Description |
|---|---|---|---|
| `ShowInInfoPanel` | `bool` | `true` | Whether this column is visible in InfoPanel |
| `InfoPanelDisplayFormat` | `string?` | `null` | Custom display format for InfoPanel |
| `InfoPanelOrder` | `int` | `int.MaxValue` | Column order in InfoPanel (lower = earlier) |
| `UrlLink` | `string?` | `null` | URL template with `{Property}` placeholders |

**UrlLink example:** `https://admin.example.com/Entity/Edit/{Id}` — renders cell as `<a href="..." target="_blank">`.

Uses compiled property accessors (`ConcurrentDictionary` cache) for performance.
