asp:Button versus asp:LinkButton

[Kevin Warnke]

I haven't tried to reproduce this in a simpler ASPX page but in my solution if I use an asp:Button button then when the postback occurs the RadEditor1.Text value is correct and shows the changes that was made.

However, if I use an asp:LinkButton when it's clicked the post back does NOT show the chnages that was just made but rather shows the original content that was put into the rad editor.

Any thoughts?

Is there something about a LinkButton that causes the editor trouble?  This is on .NET 4.0 using the 40 library from 2010 Q2.

Thanks,
Kevin

Hello Kevin,

You should not experience such a problem. I tried to reproduce the problem but without success. You can see my test in the following video: http://screencast.com/t/J7IkqBPwe2ia.

I also attached my test project. Could you please modify it at a point where the problem is reproducible and send it for examination by opening a support ticket?


Kind regards,

I can use your code and it does in fact work.

One thing I'm noticing that is different between my rendered code and yours is that ASP.NET wants to use "__doPostBackWithOptions()" for my link button.  That is new to me (must be new in .NET 4.0).

Does anyone know why ASP.NET uses __doPostBackWithOptions instead of just __doPostBack?  Is there a way to force just __doPostBack?  I'm wondering if that's doing something to reset the content.

Thanks,
Kevin

More info...

I was able to get rid of doPostBackWithOptions by setting CausesValidation=false on the LinkButton.  Then, when using doPostBack, things work just fine.  However, I need validation on these pages :)

Also, taking your sample, and adding a validator so that your link button starts using doPostBackWithOptions still works fine, so I'm not sure what to think now.

Thanks,
Kevin

Even more info... :)

When inspecting what is going on I put some jQuery into the mix.

When using the LinkButton (with doPostBackWithOptions) the "submit" event is NEVER fired.

Does the RadEditor depend on the "onsubmit" of a form to prepackage the contents into some hidden variable that gets used?  If so, can I call that method myself directly?

Hi Kevin,

Yes, exactly. The name of the method that you should call is named saveContent, e.g.

editor.saveContent(); //save the content before submission

That was what I needed, thanks!

By calling editor.saveContent() when my linkbutton click event is fired (on the client) it properly setup the data to be submitted back to the server.
