Custom Placeholder / Saving / reverting issues
|
|
|
| Stefan, thanks for your reply yesterday... I tooka different approach
and was wondering if someone could help me with this....
I created a customer placeholder control with two properties (maxlength
(int) and required (bool)). Basically, when the author tries to save
the posting, the placeholder control will check itself to see if the
text is within the constraints... if not, i display an error.. when you
raise an ErrorModeContainer.FailedSavePlaceholder it reverts the text
the user typed back to the last 'valid' version.. I'd rather have what
they typed in the control still be display for them to go back and edit
to the correct length.. here is my custom class save method...
Protected Overrides Sub SavePlaceholderContent(ByVal e As
Microsoft.ContentManagement.WebControls.PlaceholderControlSaveEventArgs)
MyBase.SavePlaceholderContent(e)
Dim errmsg As String = ""
Dim ThisPH As
Microsoft.ContentManagement.Publishing.Extensions.Placeholders.HtmlPlaceholder
= MyBase.BoundPlaceholder
If maxlength <> -1 Then
If ThisPH.Datasource.RawContent.Replace(" ", "").Length >
maxlength Then
errmsg = friendlyname & " exceeds maxlength (" & maxlength.ToString
& ")."
End If
End If
If _Required Then
If ThisPH.Datasource.RawContent.Replace(" ", "").Length = 0
Then
errmsg = "Content is required for " & friendlyname
End If
End If
If errmsg.Length > 0 Then
Dim err As New
Microsoft.ContentManagement.WebControls. WebAuthorErrorEventArgs(ErrorModeContain
er.FailedSavePlaceholder,
New Exception(errmsg))
Microsoft.ContentManagement.WebControls.WebAuthorContext.Current.RaiseErrorEvent(err)
' right here is where i'd like to set the
rawcontent back to what the user typed in if possible?
End If
End Sub

| Hm.. OK I read this and it makes sense so I changed my code... But, for
my main question, how would I go about setting the HTML/TEXT property
back to what it was the user typed in instead of reverting back to the
last saved version? IE.
Text original state before edit: Test String
Text after edit: Test String to break
After clicking save... the webauthorcontext is going to raiseerrorevent
because the length of the typed in string is greated than I am allowing
in my custom property.. So at this point, how would I keep the
placeholder text to be what the user just typed in, instead of it
reverting back to the original "Test String"

| Hi Chris,
this content needs to be in a Request.Form variable.
Pick it up there.
Cheers,
Stefan.
