I am playing around with WPF and powershell project for a tool and some learning. I have built a screen which allows you to display user information. I have added checkboxes next to each textbox so that if you edit a field then click the button it will change that section.

The issue i have is i cannot get it to work based on the selection. I have the below which works in the way it changes all fields regardless of the selection. I have played around with a few combinations but none seem to give the desired effect.

function UpdateUserInfoClick
{
    param($sender, $e)

# prepare table
$userUpdateData = @{
  Identity = $UserSearchName.text
  Server   = $UserSearchDomainSelect.text
  Credential = $ADMCreds
  GivenName = $USFN.Text
  SurName = $USLN.Text
  DisplayName = $USDN.Text
  Description = $USDesc.Text
  Confirm = $false

}

# populate entry values associated with checked checkboxes
if ($USFNCB.IsChecked = $true) {
  $userUpdateData['GivenName'] = $USFN.Text
}
if ($USLNCB.IsChecked = $true) {
  $userUpdateData['SurName'] = $USLN.Text
}
if ($USDNCB.IsChecked = $true) {
  $userUpdateData['DisplayName'] = $USDN.Text
}
if ($USDescCB.IsChecked = $true) {
  $userUpdateData['Description'] = $USDesc.Text
}
# decide on target server based on selected domain
if ($UserSearchDomainSelect.text -eq "Domain1") {
  $userUpdateData['Server'] = 'Domain1.com'
}
elseif ($UserSearchDomainSelect.text -eq "Domain2") {
  $userUpdateData['Server'] = 'Domain2.com'
}
elseif ($UserSearchDomainSelect.text -eq "Domain3.com") {
  $userUpdateData['Server'] = 'Domain3.com'
}
else {
  throw 'unexpected domain selection, cannot map to domain controller'
}
if ($userUpdateData.Count -gt 1) {
  # at least 1 updated property was checked, let's update the backend
  Set-ADUser @userUpdateData
}

}

The xaml code for one of the checkboxes

<CheckBox x:Name="USFNCB" Content="" HorizontalAlignment="Left" Margin="461,148,0,0" VerticalAlignment="Top" Height="20" Width="20" IsChecked="False"/>

Not sure if there is some more definition need for the states in the Xaml or the the set-eventhandlers?

Thanks
