Changing server-side the Title of a RadWindow once inside

[Sébastien]

Dear Telerik Team,

First, I would like to point out that the support job you do all over the year is great, and I think that plenty of developpers are really thankfull but don't say it (enough). Your job is really helpfull for us poor developpers trying to use your controls.

This said, let's process my problem :)

I have something really similar to the following code. I would like to change the title of the RadWindow "FollowUpDialog" from FollowUp.aspx. I would like to do this depeding on a server-side checked condition.

Software.aspx

                return false;
            }

Finally, I injected Javascript code.

If it helps someone, here is the code !


Software.aspx, Software.aspx.cs and FollowUp.aspx doesn't change.
