Example–Add Custom Validation for FolderNames

Task: Check new folder names that don’t exist on current level.

Solution:

1. Add a custom validation $Prop["_FolderName"].CustomValidation in the function InitializeWindow, section FolderWindow:

   function InitializeWindow
   {	
   	…
   	$mWindowName = $dsWindow.Name
   	Switch ( $mWindowName)
   	{
   		"FileWindow"
   		{
   			#rules applying for File
   		}
   		"FolderWindow"
   		{
   			#rules applying for Folder
   			$Prop["_FolderName"].CustomValidation = { FolderNameCustomValidation }
   		}
   		…
   

2. Add the function “FolderNameCustomValidation” and related search for folders:

function FolderNameCustomValidation
{
	if(-not $dsWindow.FindName("DSNumSchmsCtrl").NumSchmFieldsEmpty)
	{
		return $true
	}
	if($Prop["_FolderName"].Value)
	{
		$rootFolder = $vault.DocumentService.GetFolderByPath($Prop["_FolderPath"].Value)
		$mFldExist = mFindFolder $Prop["_FolderName"].Value $rootFolder
		if($mFldExist)
		{
			$Prop["_FolderName"].CustomValidationErrorMessage = "Folder name exists, select a new unique one."
			return $false
		}
		return $true
	}
	else
	{
		return $false
	}
}

function mFindFolder($FolderName, $rootFolder)
{
	$FolderPropDefs = $vault.PropertyService.GetPropertyDefinitionsByEntityClassId("FLDR")
    $FolderNamePropDef = $FolderPropDefs | where {$_.SysName -eq "Name"}
    $srchCond = New-Object 'Autodesk.Connectivity.WebServices.SrchCond'
    $srchCond.PropDefId = $FolderNamePropDef.Id
    $srchCond.PropTyp = "SingleProperty"
    $srchCond.SrchOper = 3 #is equal
    $srchCond.SrchRule = "Must"
    $srchCond.SrchTxt = $FolderName

    $bookmark = ""
    $status = $null
    $totalResults = @()
    while ($status -eq $null -or $totalResults.Count -lt $status.TotalHits)
    {
        $results = $vault.DocumentService.FindFoldersBySearchConditions(@($srchCond),$null, @($rootFolder.Id), $false, [ref]$bookmark, [ref]$status)

        if ($results -ne $null)
        {
            $totalResults += $results
        }
        else {break}
    }
    return $totalResults;
}

3. Update the Dialog definition File.xaml: Navigate to the Textbox "FILENAME" and update the binding Text="{WPF:ValidatedBinding Name}" to Text="{WPF:ValidatedBinding Prop[_FolderName].Value}". The new TextBox definition looks like this:

<TextBox Text="{WPF:ValidatedBinding Prop[_FolderName].Value}" x:Name="FOLDERNAME" 
                     IsReadOnly="{Binding EditMode}"
                     Visibility="{Binding NumSchmFieldsEmpty, ElementName=DSNumSchmsCtrl, Converter={StaticResource BooleanToVisibilityConverter}}" 
                     Grid.Column="1" Grid.Row="3" />
