# HierarchialGridArgs

`HierarchialGridArgs` is the strongly-typed configuration object passed to the `Add` overload for `clsUltraGridBinder / clsWebHierarchicalDataGridBinder`, carrying the standard bind configuration plus control-specific settings. Carries per-band key configuration for hierarchical grid binding.

## Purpose
- Configure a binding to `clsUltraGridBinder / clsWebHierarchicalDataGridBinder` without a long positional `Add` call.

## Context
- Namespace: `SAIF.Presentation.Web.Binding`
- Assembly/package: `SAIF.Presentation.Web.Binding.Infragistics111` (ILMerged into `SAIF.Presentation.Web.Infragistics111.dll`)
- Base class: `clsObjectBindingArgs`

## Public members
| Member | Signature | Purpose |

| GetKeyProperty | `Public Function GetKeyProperty(bandIndex As Integer) As String` | Returns the key property name for a given hierarchical band, used to resolve the correct grid row for a child-band object during validation and write-back ([BR-BIND-025](../../business-rules.md#br-bind-025-hierarchical-grid-write-back-recurses-child-bands), [BR-BIND-049](../../business-rules.md#br-bind-049-grid-row-located-by-key-property)). |
