c# - Nested Masterpages and .FindControl -

-

On one site, I'm using only one level masterpiece and in that one page using that master, I I can do this. To access Master.FindControl ("controlName") control. works fine.

However, using the same code on the site containing two masterpap levels. Main Master and Specialist, who is Chief Master in Master Master.

Therefore, returning empty for FindControl object, on a page using specific master. When I set a breakpoint and see the page. Mester, this is showing a typical master and the typical master is showing the mastermind as the right owner, but FindControl is still unsuccessful.

When I look at the source in IE, the control is properly named, no .net mungbean is running.

Any ideas here?

TIA!

When you're nesting master pages, you will get an additional container "content" Which you need to see.

As a result, if you are trying to use FindControl from a given child page, then the general approach affects: 

  label myLabel = (label ) This.Master.FindControl ("mylabel"); MyLabel.Text = "Success!";

Since we have a nested master page, because the child has "myLabel" in the master, this control will be contained in the control.

Therefore, change this code to: 

  ContentPlaceHolder ph = (ContentPlaceHolder). Master.Master.FindControl ("yourContentPane"); Label myLabel = (label) ph.FindControl ("myLabel"); MyLabel.Text = "Success!";

and VB.NET 

  Content as a page pdf.de = Direct Seite (Me.Master.Master.FindControl ("YourContentPane"), content placeholder) labeled as "MyLabel = Direct Season" (pH fund control ("my label"), label) myLabel.Text = "success!"

The contents of the child page are loaded in the first master page control, which is then loaded in the grandparent's master page.

I am getting an error with php in order to format mysql_query () in php to format this string What is the right way? SELECT SELECT SELECT (*) Agents @AgentCount; User_Agent_English, User_Angent_Oursal, US.___Gent_Aginal, COUNT (User_Agent_Percade) ACC, COUNT (*) / (AgentCount) Percentage by agents user_agent_preser order DEC limit limit 50; In PHP, how am i setting $ query $ query = "SELECT count (*) agents @ agentcount; SELECT user_agent_parsed, User_agent_original , COUNT (user_agent_parsed) ascount, COUNT (*) / (@AgentCount) as a percentage by user_agent_parced by URI date DESC limit 50 "; This exact query will work properly if I put it in MySQL directly through a command line session. Do I need to release two separate php calls from mysql_query () and store the results first? I get the following error: There is an error in your SQL syntax; Instead of using a sub-selection and instead of using the 'SELECT user_agent_parsed, user_agent_original, ne...

url rewriting - How to implement the returnurl like SO in PHP? -

-
This URL should work even after the rewrite. Is this possible? Otherwise, I can only hardcoded everything If you are trying to create a login system with redirection You need to use the HTTP_REFERER header to find out where the user came from so that you can send it back there. The best way to do this is to use something like this in your login form: // - Login php & Lt; Input type = "password" name = "password" /> & Lt; Input type = "hidden" name = "returnrelale" value = "& lt ;? php echo $ redirectURL ;? & gt;" / & Gt; & Lt; / Form & gt; Please note that some ISP, browser or proxy will delete the referrer header, so you can not rely on each user to work fully. If you use a statement, to check whether the header exists or not, you can send those users back to the homepage or whatever. Edit If you are looking to use $ _SERVER ['REQUEST_URI'], if you are running Apache It sho...

Which Python client library should I use for CouchdB? -

-
I am starting to experiment with CouchDB because it looks like we have the right solution to certain problems That all the work will be on a new project, which does not have any legacy dependency, which the client library will suggest you use, and why? If we overlap any of the OS. Freeband is available only in the collection of its ports, but asks to use the library's project website. None of those people are Ubuntu, which is only with ships, since those two OSAs are not common in libraries, I am probably installing something from source (and hopefully if I have time, then Ubuntu and FreeBSD People pack the package). For those interests, I want to use CouchDB as a convenient intermediate storage space for data passed between different services - think of a message bus system, but less formalities with. For example, we have daemons that download and pars the web page, then send an interesting bit to other daemons for further processing. Many of them are ill-defined until the...
