# InfragisticsGridCustomizerList

`InfragisticsGridCustomizerList` is the per-page collection that lets a model host customization state for multiple grids at once. [ModalGridCustomizer](ModalGridCustomizer.md) expects to find (or create) this list under the model's `GridCustomizers` property, keyed by grid ID, so a single page with several `UltraWebGrid` instances can maintain independent customization state for each. ([BR-AJAX-021](../../business-rules.md#br-ajax-021-grid-customization-state-is-created-once-per-grid-per-model-and-reused))

## Purpose
- Holds one [InfragisticsGridCustomizer](InfragisticsGridCustomizer.md) per grid ID on a single model, so `ModalGridCustomizer` can look up the correct instance for its `TargetControls.GridId`. ([BR-AJAX-021](../../business-rules.md#br-ajax-021-grid-customization-state-is-created-once-per-grid-per-model-and-reused))
- Provides a stable, model-scoped home for customizer state so it survives postbacks for the life of the model (typically session-scoped in the SAIF MVC layer).*

## Context
- Namespace: `SAIF.Presentation.Web.Controls.V2.AJAX`
- Assembly/package: `SAIF.Presentation.Web.Controls.AJAX.Infragistics111` (packaged in `SAIF.BOF.Presentation.Web.Infragistics111`)
- Base class: `Generic.List(Of InfragisticsGridCustomizer)` (.NET Framework)

## Public members

This class adds no members beyond those inherited from `Generic.List(Of InfragisticsGridCustomizer)`; `ModalGridCustomizer.GridCustomizer` locates an entry by matching `TargetGridId` against each element via a `Linq`-style lookup rather than through a dedicated indexer or key-lookup method on this class.

<!-- SELF-CONTAINMENT: base type Generic.List(Of InfragisticsGridCustomizer) is a .NET Framework generic collection, not part of this repository's own doc set; no Inherited public members section is produced. -->

## Behavioral notes
- The model must expose a property literally named `GridCustomizers` of this type for `ModalGridCustomizer` to find or populate it; a missing property surfaces as the `ApplicationException` documented on `ModalGridCustomizer.GridCustomizer`.*

## Constraints and usage notes
- Intended to be created once and reused, not rebuilt on every postback, so that each `InfragisticsGridCustomizer`'s in-memory state (and any unsaved session customizations) persists across the page's lifecycle. ([BR-AJAX-021](../../business-rules.md#br-ajax-021-grid-customization-state-is-created-once-per-grid-per-model-and-reused))
