MgGrid — Columns

Part of the MgGrid system. See README.md for overview and component hierarchy.

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)
InfoPanelEditTemplate	RenderFragment<MgGridInfoPanelEditContext>?	null	Custom InfoPanel editor (edit mode) — takes precedence over the EditSettings / property-type default editors
UrlLink	string?	null	URL template with {Property} placeholders

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

InfoPanelEditTemplate

Use when the grid-side editor is a CellEditTemplate the InfoPanel cannot reuse (it is bound to the grid-cell context) — without it, the panel falls back to the property-type default editor (e.g. int → number spinner). Context: MgGridInfoPanelEditContext(object EditModel, Action Refresh) — call Refresh() after mutations other fields depend on (cascading lookups), it re-renders the InfoPanel.

<MgGridDataColumn FieldName="CategoryId" Caption="Category">
    <CellEditTemplate>@CategoryEditor((MyItem)context.EditModel)</CellEditTemplate>
    <InfoPanelEditTemplate>@CategoryEditor((MyItem)context.EditModel, context.Refresh)</InfoPanelEditTemplate>
</MgGridDataColumn>

Define the editor once as a shared fragment (private RenderFragment CategoryEditor(MyItem item, Action? refresh = null) => @<DxComboBox ...>;) so the grid cell and the InfoPanel render the same component — no duplicated markup.

Uses compiled property accessors (ConcurrentDictionary cache) for performance.
