Hi

I'am trying to write a custom placeholdercontrol based on
HtmlPlaceholderControl
public class xxxxxPlaceHolderControl : HtmlPlaceholderControl
Actually , i wrote some code in méthods:

CreateAuthoringChildControls

CreatePresentationChildControls

LoadPlaceholderContentForAuthoring

LoadPlaceholderContentForPresentation

SavePlaceholderContent

All was working well



but my need is that one of the textbox that I add in
LoadPlaceholderContentForAuthoring must be filled by the operator

so I want that the user cannot complete save ( or save and exit ) in
authoring mode.

In order to achieve this  , i implement the method

 OnSavingContent(PlaceholderControlSaving
EventArgs e)

where  i wrote :

if ( mytest ... ) {

e.cancel = true;

}

My problem is that when e.cancel is set to true, the page displays a blank
screen with only the  console and my custom control disapear.

in fact, the method LoadPlaceholderContentForAuthoring is not called when
e.cancel is set to true

I thinked that OnSavingContent is an equivalent to beforeUpdate, but finally
it don't work like this



so i have tried a call to  LoadPlaceholderContentForAuthoring in
OnSavingContent :

where  i wrote :

if ( mytest ... ) {

e.cancel = true;

LoadPlaceholderContentForAuthoring( new
PlaceholderControlEventArgs(e.Posting) )

}

this code works, but i'am not sure that is  something to do because the mode
switch between unplublised and saved

and the problem with 'Save and exit' is still there because the page close
with the old value of my textbox, so the operator doesn't no

that his operation do not complete . How can I stop the event closed of a
page if conditions aren't fullfiled



thanks

Hi,

this approach will not work correct as parts of the page will be saved and
parts not as the events for the different placeholder controls fire
independendly.
So if you cancel the save for one placeholder control all others might
already be written to the database.

You should implement a custom save action which checks if the relevant
placeholder controls are filled and only do the save action if this is true.

Cheers,
Stefan.

Hi

thanks for you help

I wrote a customSave Class that inherit from the standard
one(AuthoringReeditSaveAction ) and I use it in the console

from now I can check if one of my input is missing and cancel save action by
calling GenerateStartupScriptRepost with original url
in method PerformActionBehavior

My problem now, is to show the operator an error message.
As i do a postback with GenerateStartupScriptRepost i can add values to url
in order to read this values in method LoadPlaceHolderForAuthoring.
In this method I can create a new Exception ( type of  error saving Content
placeholder ) that will be shown in the error console.

This works well but now the link Save , Save and Exit disappear, => i have
got a new problem to solve 

Bye
