Create editable powershell GUI for CSV data - csv

Question

GOAL: Create a GUI form populated with CSV data, allow the user to edit the data, then save the data in an array for further manipulation.
NOTE: Using PowerShell Studio to generate a form with data from the CSV
CURRENT CODE:
- Calling code ($path is passed from the calling form):
$rows = Import-Csv -Path $path
$table = ConvertTo-DataTable -InputObject $rows
Load-DataGridView -DataGridView $datagridviewResults -Item $table
ConvertTo-DataTable function:
function ConvertTo-DataTable {
[OutputType([System.Data.DataTable])]
param(
[ValidateNotNull()]
$InputObject,
[ValidateNotNull()]
[System.Data.DataTable]$Table,
[switch]$RetainColumns,
[switch]$FilterWMIProperties
)
if($Table -eq $null) {
$Table = New-Object System.Data.DataTable
}
if($InputObject-is [System.Data.DataTable]) {
$Table = $InputObject
} else {
if(-not $RetainColumns -or $Table.Columns.Count -eq 0) {
#Clear out the Table Contents
$Table.Clear()
if($InputObject -eq $null){ return } #Empty Data
$object = $null
#find the first non null value
foreach($item in $InputObject) {
if($item -ne $null) {
$object = $item
break
}
}
if($object -eq $null) { return } #All null then empty
#Get all the properties in order to create the columns
foreach ($prop in $object.PSObject.Get_Properties()) {
if(-not $FilterWMIProperties -or -not $prop.Name.StartsWith('__')) { #filter out WMI properties
#Get the type from the Definition string
$type = $null
if($prop.Value -ne $null) {
try{ $type = $prop.Value.GetType() } catch {}
}
if($type -ne $null) { # -and [System.Type]::GetTypeCode($type) -ne 'Object')
[void]$table.Columns.Add($prop.Name, $type)
} else { #Type info not found
[void]$table.Columns.Add($prop.Name)
}
}
}
if($object -is [System.Data.DataRow]) {
foreach($item in $InputObject) {
$Table.Rows.Add($item)
}
return #(,$Table)
}
} else {
$Table.Rows.Clear()
}
foreach($item in $InputObject) {
$row = $table.NewRow()
if($item) {
foreach ($prop in $item.PSObject.Get_Properties()) {
if($table.Columns.Contains($prop.Name)) {
$row.Item($prop.Name) = $prop.Value
}
}
}
[void]$table.Rows.Add($row)
}
}
return #(,$Table)
}
Load-DataGridView function:
function Load-DataGridView {
Param (
[ValidateNotNull()]
[Parameter(Mandatory=$true)]
[System.Windows.Forms.DataGridView]$DataGridView,
[ValidateNotNull()]
[Parameter(Mandatory=$true)]
$Item,
[Parameter(Mandatory=$false)]
[string]$DataMember
)
$DataGridView.SuspendLayout()
$DataGridView.DataMember = $DataMember
$DataGridView.EditMode = 'EditOnEnter'
if ($Item -is [System.ComponentModel.IListSource]`
-or $Item -is [System.ComponentModel.IBindingList]`
-or $Item -is [System.ComponentModel.IBindingListView]) {
$DataGridView.DataSource = $Item
} else {
$array = New-Object System.Collections.ArrayList
if ($Item -is [System.Collections.IList]) {
$array.AddRange($Item)
} else {
$array.Add($Item)
}
$DataGridView.DataSource = $array
}
$DataGridView.ResumeLayout()
}
ADDITIONAL INFORMATION: Code is working in that it generates the Grid View and populates it with CSV data. However, I cannot edit it and need help coding the ability to capture changes once it is edited.
Thanks in advance.
12/5 EDIT: Added "$DataGridView.EditMode = 'EditOnEnter'" to the function "Load-DataGridView" above. Nothing changed. Tried to invoke the "BeginEdit" Event in a new RowCellClick event, but that didn't work either. Still struggling with this one.
