# ModalGridCustomizer.TargetControlIDData

`ModalGridCustomizer.TargetControlIDData` is the page-declarable, expandable property bag through which a hosting page identifies the target grid and its supporting controls for a [ModalGridCustomizer](ModalGridCustomizer.md) instance.

## Purpose
- Holds the ID of the `UltraWebGrid` to customize (`GridId`), an optional linked control to refresh after applying changes (`LinkedRefreshControlID`), and the page's object-binder control ID used when `BindingBehavior = ObjectBinder` (`ObjectBinderId`).
- Decorated with `TypeConverter(GetType(ExpandableObjectConverter))` so the property appears as an expandable sub-property group in the Visual Studio WebForms designer's Properties grid.

## Context
- Namespace: `SAIF.Presentation.Web.Controls.V2.AJAX`
- Assembly/package: `SAIF.Presentation.Web.Controls.AJAX.Infragistics103`
- Declared as a nested `Public Class` inside `ModalGridCustomizer`; exposed via `ModalGridCustomizer.TargetControls`.

## Public members
| Member | Signature | Purpose |
| --- | --- | --- |
| GridId | `Property GridId() As String` | The ID of the `UltraWebGrid` control on the same page that this customizer manages |
| LinkedRefreshControlID | `Property LinkedRefreshControlID() As String` | Optional ID of a WARP (`WebAsyncRefreshPanel`) refreshed when the user clicks OK/Apply in the popup; if not supplied, the Apply button is not rendered |
| ObjectBinderId | `Property ObjectBinderId() As String` | The page's `clsObjectBindManager` control ID, used only when `BindingBehavior = ObjectBinder`; defaults to `"objBinder"` |

## Behavioral notes
- `ModalGridCustomizer.TargetGrid`/`ObjectBinder` property getters throw `ApplicationException` if `GridId`/`ObjectBinderId` cannot be resolved to an actual control via `Page.FindControl`.

## Constraints and usage notes
- `GridId` must reference an actual `UltraWebGrid` control on the same page for the customizer to function.
- `ObjectBinderId` is only consulted when `ModalGridCustomizer.BindingBehavior` is set to `ModalGridCustomizer.BindingBehaviors.ObjectBinder`.
