Placeholder content lost in first save
|
|
|
| Hi all,
I have a template with a HTMLPlaceholder definition and a dropdownlist web
control. When an item of the list is selected, the selected value is stored
in the placeholder
(placeholder.datasource.rawcontent=list.selecteditem.value).
Then when I save the posting for the first time and then I close the browser
and open the posting again, the content of the placeholder is not there
(placeholder.datasource.rawcontent="").
The most extange is that if then I select another item from the list and
save, the value is stored in the placeholder fine.
Any idea of what is wrong here?
Thanks for your help

| Hi ETX,
I have found it is much easier to stored these types of values in custom
propreties. I had similar problems when I tried to use html placeholders. I
think it may be becuase the control is trying to update the content is has
and this is over writing the data you set in raw date. It is also important
to use the Microsoft.ContentManagement.WebControls.WebAuthorPostingEventArgs
e passed to the SavePostingEvent instead of the CmsHttpContext.Current. Your
code will look something like this
protected void SavePostingEvent(object sender,
Microsoft.ContentManagement.WebControls.WebAuthorPostingEventArgs e)
{
e.Posting.CustomProperties[PROPERTY_NAME].Value =
DropDownlist.SelectedValue;
}
I hope this helps.

| Hi ETX,
you need to do this using a custom placeholder control and not with code
behind.
That will not work and lead to the effect you have seen.
In addition you should never use Datasource.Rawcontent.

| Thank you Stefan and Mike,
Finally I added an HTMLPlaceholdercontrol and used the contentsaved event of
the control to store the custom property. That solved the issue.
I am going to make a revision of the code of the whole application to remove
the "datasource.rawcontent" cases. I am affraid that we have used that more
than once...
Thank you both a lot.
