            if(CategoryNames[i] == name.ToString()) return i;
        return -1;
}

// ...
private void pivotGridControl1_FieldValueImageIndex(object sender, 
  PivotFieldImageIndexEventArgs e) {
    if(e.Field == fieldCategoryName && e.ValueType == PivotGridValueType.Value) 
        e.ImageIndex = GetCategoryIndexByName(e.Value);
    if (e.ValueType == PivotGridValueType.GrandTotal && e.IsColumn == false)
        e.ImageIndex = 8;
}

         While i < CategoryNames.Length
            If CategoryNames(i) = name.ToString() Then
               Return i

            i += 1
         End While
   End If
   Return -1
End Function

    If e.Field = fieldCategoryName1 AndAlso e.ValueType = PivotGridValueType.Value Then
        e.ImageIndex = GetCategoryIndexByName(e.Value)
    End If
