From: TS on 15 Apr 2010 10:04 thanks zhi-qiang, but I am still having problems...the postbackURL is blank all the way thru page execution life cycle. It is never set and it is always blank. What else could cause this? thanks "TS" <manofsteele1(a)nospam.nospam> wrote in message news:u2ioBK9vKHA.3536(a)TK2MSFTNGP06.phx.gbl... > hello, I don't see that you replied to my previous post sent on 02/22: > > postbackUrl is empty string - checked at time of rendering the control. > > I had already looked into this as a possible reason but its not the case. > > thanks > > "Zhi-Qiang Ni[MSFT]" <v-zhiqni(a)online.microsoft.com> wrote in message > news:R4mIzmTqKHA.2332(a)TK2MSFTNGHUB02.phx.gbl... >> Hi TS, >> >> Sorry for my delay.

From: TS on 15 Apr 2010 10:07 from the URL you sent me, it says the following which indicates that even if you don't enter PostBackUrl it will use current page: "Set the PostBackUrl property to the URL of the Web page to post to when the Button control is clicked. For example, specifying Page2.aspx causes the page that contains the Button control to post to Page2.aspx. If you do not specify a value for the PostBackUrl property, the page posts back to itself." so it is using the current page whether specified or not. please help "TS" <manofsteele1(a)nospam.nospam> wrote in message news:u2ioBK9vKHA.3536(a)TK2MSFTNGP06.phx.gbl... > hello, I don't see that you replied to my previous post sent on 02/22: > > postbackUrl is empty string - checked at time of rendering the control. > > I had already looked into this as a possible reason but its not the case. > > thanks > > "Zhi-Qiang Ni[MSFT]" <v-zhiqni(a)online.microsoft.com> wrote in message > news:R4mIzmTqKHA.2332(a)TK2MSFTNGHUB02.phx.gbl... >> Hi TS, >> >> Sorry for my delay.
