Re: Child Controls Showing as Null Ennis Ray Lynch, Jr.1-Sep-10 7:26 Ennis Ray Lynch, Jr. 1-Sep-10 7:26  What event in the Page Lifecycle is your code running? Child controls generally will not be available until after the load event fires for said control. That said, code is not supposed to access controls up the hierarchy only below it. If you need to access something from your parent container, the parent should provide a method to perform said action. Otherwise you introduce unmanageable dependencies. Need custom software developed? I do custom programming based primarily on MS tools with an emphasis on C# development and consulting. I also do Android Programming as I find it a refreshing break from the MS.

What I do at first is a FindControl() on the current control, if its not found, it does a a FindControl() on the page which the control is on. If thats not found, it looks at the Master for that Page and continues to do this until the control is found, or it is the root masterpage. It only seems to find controls outwith the content place hold on the root masterpage or nested content controls. Interestingly, on the Controls collection, it shows the correct number of the page, however some are shown as null. I'm sure the nulls are where my controls I need to find are. Thanks DM ASP.Net State Service doesnt exists in IIS7 indian14331-Aug-10 7:09 indian143 31-Aug-10 7:09  Hi All, I am new to Windows7 and IIS7 environments. Here at client site, I have a machine in which I am not finding ASP.Net state service in my services list. Is there any way to add ASP.Net state service to the services list. I need this service to be added because the application I am running is using ASP.Net state server services. Any link or any explanation would be great helpfull. I need this support for Windows7 and IIS7. Thanks & Regards, Md. Abdul Aleem NIIT technologies Re: ASP.Net State Service doesnt exists in IIS7 T M Gray31-Aug-10 11:36 T M Gray 31-Aug-10 11:36  Windows 7 isn't a server operating system. If your site is big enough to require state services it should be running on a server OS. Also depending on how you use the website you may be violating the license agreement for the desktop OS if you are serving a website for multiple users.

Thanks, Mark Saving a user's location on a page Aptiva Dave30-Aug-10 10:06 Aptiva Dave 30-Aug-10 10:06  Quick question: A department I am working for has asked that I come some functionality on their web site for their users. The site holds student data broken down by schools. The users with schools that have a large number of students want to be able to go from the page that lists all of their students to the student's information page and then back to the list starting where they left off. The list of students is presented in a gridview control, so I was wondering if there was a way I could save where the user was in the gridview so that when they finish looking at a student's information they can start back on the gridview from where they started from. Re: Saving a user's location on a page Ennis Ray Lynch, Jr.30-Aug-10 10:46 Ennis Ray Lynch, Jr. 30-Aug-10 10:46  Yes there are numerous ways to get at your goal. Need custom software developed?

Either use the cached version or look for one of the other of hundreds of articles about using the MaintainScrollPositionOnPostback directive. Re: Saving a user's location on a page David Mujica30-Aug-10 11:05 David Mujica 30-Aug-10 11:05  Cookie I've never used them, but I believe you could create a cookie with "key" information like the student ID so that when you come back to the Grid page, you could load it at the right location. Session variable Same idea as a cookie, but the implementation is a bit different Pop-Up You could make the Student Detail window appear as a new browser window, so they can see the student info in one window and the grid remains untouched in another window. Just some ideas ... Re: Saving a user's location on a page Aptiva Dave31-Aug-10 4:35 Aptiva Dave 31-Aug-10 4:35  Yeah, I tried the pop up idea, but the more I think about it I get fears of calls in the middle of the night about users not being able to use the site because they have turned off their pop up blocker. I'm using Session variables already, so that and cookies aren't a stretch for me. Thanks for the advice. Re: Saving a user's location on a page NeverHeardOfMe30-Aug-10 11:59 NeverHeardOfMe 30-Aug-10 11:59  It's easy enough, assuming you're creating links for each student in the RowDataBound event based on their ID number. Then simply add (Attributes.Add) a "name" property to each link also based on their ID, and append this anchor name to the "Back" link url on their student info page (....aspx#s123, for example) Re: Saving a user's location on a page Aptiva Dave31-Aug-10 4:39 Aptiva Dave 31-Aug-10 4:39  This seems to be the easiest to add in my current situation, and an obvious no-brainer. If I had thought of this before spending days messing with javascript and jQuery pop ups then I would be closer to being finished.

I used the book the last time I did a project using iTextSharp and didn't run into any issues. Re: header, footer , page number in iTextSharp Dhyanga30-Aug-10 9:39 Dhyanga 30-Aug-10 9:39  iTextSharp is working I guess. Well I can see my data in pdf format already. Just need to add header and footer in that. I am using iTextSharp in my project which is in asp.net using C#. Also I included iText.dll in my project but it doesn't seem like its working. suchita Re: header, footer , page number in iTextSharp T M Gray30-Aug-10 10:59 T M Gray 30-Aug-10 10:59  I am not saying to use the iText dll, I am saying to use the book to figure out what method calls and properties to use to accomplish your task.
