State Management :: Master Page's Treeview Selected Node / Setting The Properties In Master Page?
Aug 2, 2010
I have a master page containing a tree and 3 dropdown lists. I am populating a context menu on right click of each node, and when clicked on any item of the context menu, it navigates to required pages.
My problem is after navigating to the required page, the selected values from the drop down lists and the selected node from the tree are getting cleared.
I can set the selected values for the dropdown lists by making some properties in master page.
But how do i maintain the selected node?
In my content page, i have got the valuepath of the right clicked node.
Or is there any other way than setting the properties in master page?
I have created a matser page with a two radio buttons, text box and a button. Whenever user sets some values to these control and clicks the button, i will navigating him from one content page to another based on the data he has entered. The problem is after the content page load, the values selected/given in the controls(radio button, text box) are getting cleared.
I have a Web Application where I have one and only one master page and with 100's of diffrent content pages
So to speed up my Web app How can i CACHE the mater oage but not the content page??
Master page loads each time whenever content page is requested..
This thing is possible,I have seen it on many diffrent websites where the Website's Master Page Remains Intact and only the content page changes (best example would be Facebook)
How can i have the same effect in my Web Application?
Please bare with me as I am completely new to ASP.net and trying to learn the language (I am a Flash and AS3 kinda guy).
I have a master page template and I'm trying to put a hit counter on the footer for each page. I'm using VB for this code.
[Code]....
And then in the footer div I use this code
[Code]....
It appears my counter.txt file isn't even being created like it normally was on my other single .aspx pages and in turn nothing is being displayed in my Label1.
Im trying to use code provide in this link below.http://www.codeproject.com/KB/aspnet/MultipleTabWindows.aspxim trying to have the below code in my master page instead of adding to each page. it works if i add to each page, but when i add to ,master page the session value for "WindowName" is always null.how can i fix this?
I have a nested master page that I use for multiple pages. There is a ContentPlaceHolder that is used for only one page, but it is not shown until after the first postback and some validation. I was first trying to use static controls and set the Visible property on the ContentPlaceHolder to true after the postback and that did not work at all. Then was messing with the visible properties of the Individual controls inside the ContentPlaceHolder which also did not work. I have the EnableViewState set to false for the Page and each of the controls including the ContentPlaceHolder. Is there a better way to do this? I can post my code if need be just wanted to see if there was a better solution to this before I did.
In my web application, I have to load different Master pages depending on the user log-in information. When I say different, I mean not just the colors but a whole new look[including navigation options]. So I am using 2 Master pages [one of them is set as default] and depending on the user information the other page will be used.
I got it to work by storing the user information in a Session variable and applying the master page dynamically using the Page_PreInit event. But the issue is, if I hit the back button, sometimes [yeah, only sometimes !!!] the master page is reset to the default page. Initially I thought it is a Session timeout issue. But it isn't, as some of the session variables still have data. Can anyone explain whats actually happening?
I am working on a functionality of user right, in which admin is selecting the pages and the user and save it. so whenever that user will login into the system then he will be able to see only those pages which were selected and saved for him by the admin.
now for that i have created one page for the list of pages of the application and user list and i am storing them into the database. and then to hide and show the panels i have created the BaseWebPage in my application but here i am not able to get the master page to hide the panel and show only those which are permitted. i dont have much knowledge of BaseWebPage. i am working in framework 2.0 and i have links of all pages that i have shown in a master page in a panel.
Can I modify the properties of a content page control from an event fired from the master page?create a delegate and event on master page wire up the master page in the content page create the event handler (function) on the content page modify for example:
contents of the Text property of a textbox render a control visible (or hidden) etc...
Am new to asp.net.I am creating a site using asp.net(C#), in master page i have treeview control, when i select a item i navigate to url. But selected node is lost, it reset itself, loosing state.
I have been getting this error a lot lately with some of my users, and I had a couple of concerns with view state and I have read so many articles but I am still lost..
1. I use masterpage on all the pages and I need viewstate for some of the pages but..
There is a page where a user will fill out the information and then submit this data to a cgi server, and it is where I get most of the Client Disconnected errors, what would happen if I disable viewstate when they click on that button?
Now when a user browses from one page to another, does the view state from the previous page get deleted? If not how would I delete it?
Does the master page have its own viewstate? Would I be able to make sure none of items on my master page are using the viewstate?
There are different ways to set the title for content pages from Master page
by findcontrol by creating property in master page and setting the value in content page
As both method requires an object creation of master page which will be little heavy myMasterPage myMaster = (myMasterPage)this.Master;
so I have tried it by creating a class and it worked -
public class clsmaster { public static clsmaster objmaster = new clsmaster(); public strtitle {get;set;} }
Now I just need to access this static object and set the property in the content page and in the master page I just need the controls to take the value from this class (clsmaster).
Private _theskin As String Public Property theskin() As String Get Return _theskin End Get Set(ByVal value As String) _theskin = String.Empty End Set End Property
I was then expecting to be able to access these properties from the default.aspx.vb page in this way;
If Master.theskin = foo Then do things End if
In the default.aspx.vb the code is highlighted with blue underline and says;
theskin is not a member of system.Web.Ui.Masterpage
Am I making an error somewhere along the line? Do I need to do more to be able to expose the properties to default.aspx.vb?
I have created one website with Master and content page . I have taken TreeView Control on master page. And I wants that when I click to tree node the i can get value of tree node on content page and bind the dropdown of content page according to value of master page.
Here's the scenario: A class based on System.Web.UI.Page has been created. A number of content pages derive from this class. All of these content pages use the same master page. The content pages define controls which need to access things on the master page (in code-behind). This is fine - no problem. In particular, each content page has its own data grid. The grid on each page has the same name, so that common code can reference it. In fact, some event handling for the grids on each content page is identical, so would like to factor that code to the base class. Interestingly, I can actually define the event handler entirely in the base class, with no stub in the content class at all, because the wire-up of event handlers uses the event-handler name defined in the grid, and that name happens to be found in the inherited base class. All good and dandy... very cool in fact. The problem comes when the code in the base class needs to access any of the common elements from the content page's master. Remember, the master is the same, and I know the type of the master. I would like to do something like this in the base-class code:
((myMasterType)this.Master).PropertyofMaster=xxx;
The problem is, that myMasterType - the type of the master page the content pages are using - is not available at compile time, at least not from a class definition for a base page. I've found articles that claim that the class name of the master is available - and it is, but not from a separate class. I CAN see it and compile with the master's class name from, for example, the code behind of the various content pages. But the actually class simply isn't available, it seems, from a pure class (the base page class). Judging from other times this question has been asked, here are common misunderstandings offered as solutions: 1. Use a page directive to declare the master type. This is not even vaguely a part of the problem, as the issue is not code in the content page, but in a separate base class which content pages inherit from. That base class is a pure class -- no .ASPX file at all. 2. Pass a reference to the master object from the content page to the base class. This can be done, but is pointless, because I can already get it, using "this.Master" from the base class! But because the type of the master is not available at compile time from the base class, it can't be passed from the content page either - unless it is passed with type MasterPage, thus losing all the properties/methods publically defined in the specific master page class. 3. Move the base page class out of the App_Code folder because the app_code folder is compiled before the other classes, and thus before the master page class. Doesn't work -- put the master page class file right in the same folder with these content pages and their master page, and the master page class is still not available at compile time from within the class. Re-summarized: Base page inherited by content pages. Content pages all use a common master page. Want to access the public properties of that master page from the base page, at runtime. Barrier is that I can find no way from within the base class to cast the master page object to the actual master page subclass being used.
I have our site setup with 2 master pages.. one is for the general public and the other is for our admin section..
We are going to be updating the general pages to check the users job title to help customize the pages for them. Is it possible to add the code we are going to use to set the sessions to the master page of the general section and have it set the sessions. Or will i have to update each page individually with the logic and handle each page seperatly?
I have another post asking for help on setting the sessions, but once that is done, i'd like to know if adding that code to the master page will accomplish what i want, by just having it in one place and easier to maintain. Or will i have to add the code to each page i want to check the session values...

I have a master page setup that is used throughout my site that is basically a header with a menu. I recently added a textbox and a button to this master page which is to be a quick search box that is available anywhere in the site. When a user enters text into the search box and hits the button, I need to load the actual content page which is used to search and show search results (which also uses this same master page), and have the text entered available so the search can be triggered automatically. Again, this search text box and button is now in my master page so it could be triggered from anywhere in the app... it serves as a convenient way to do a basic search from anywhere in my app, without having to first navigate to the actual 'search page' that already exists. You can also navigate to the actual search page, which uses the same master page, where there is many more search options.I'm thrown off by the master page arrangement, which I have not used until this project. What do I do?
Is it possible to inherit a sharepoint master page(as a parent) in another application's master page which will be treated as child (i.e. after integrating that standalone application with the sharepoint application)? I am totally new to Sharepoint..
I Have a TreeView that I populate from a DataTable.Once it has been populated, I Cache the Treeview.If I try to add the cached TreeView control to my page, nothing happens. No errors no nothing.If I create an empty TreeView control on the page and do a "Do Until" loop and add each node to that empty TreeView, that works! but only once. The next time it loops, for some reasion the CachedTree.Nodes.Count = 0.I can't see what I'm doing wrong.
