Web Forms :: MasterPage Controls Resetting On Postback From ContentPlaceHolder Pages
Nov 18, 2010
Probably a simple fix to this I am not sure. Basically, I have a MasterPage that contains a Dropdownlist. This DDL controls what is displayed in ContentPlaceHolder. However, when postbacks are caused within the Contact Pages the DDL is resetting itself. How can I keep the selected value for the DDL between postbacks?
When I click on one of my treenode, I need to set the node.target to the "ContentPlaceHolder1", ie, keep the tree menu as still and let the content page displayed at the right part of the page. However, the node doesn't seem to recognize the ContentPlaceHolder1.
2. I have tried using <frameset> with 2<frame> pages, this way, the node.target can recognize the frame id, code as below:
But, I need to check user's login permission, I did it with session("userId") variable and I ran into a problem that the session will only exists on the left frame(menu.aspx), not the content page(Main.aspx). I have tried both methods, but one way or the other, there is some function that I cannot accomplish.
I have a master page that contains a menu, the menu contains links to pages outside the website, how do get those links to open up in the main contentplaceholder of the master page? I tried setting the target to the ID of the contentplaceholder but that didnt work.
is it possible to put two different contentPlaceHolder from two different ASPX page in one MasterPage? Just like iFrame? if not what asp.net process/control can?
I'm about to create a masterpage that contains a search field, the result from the search should be placed inside a contentplaceholder, but how do I build that? I added the search form to the masterpage (not inside a contentplaceholder), and then I added the eventhandler for the button that trigger the search. Now lest say I want to display the result in the contentplaceholder, how would I do that?
I have a web site that works fine on the server. I purchased a new domain and set that up on my web server and set the home directory on to the server to the same location as the site that works.
However, my forms authentication ticket is being recreated on every page post back. Is there some setting in IIS that I'm missing under the new domain(IP)? If I access the site under one domain the ticket is saved and tracked fine. When I access it from the second domain (same home directory as first domain) the ticket is lost on postback.
I have added two contentplaceholders on my master page.
My Treeview navigation is on the master page. When i Click a link on treeview a parameter page (Para.aspx) must be loaded on Contentplaceholder1 and When i click preview button on parameter page (Para.aspx) report must be loaded in to contentplaceholder2 on master page.
I currently have three masterpages and content pages in the following hierarchy: One root-level masterpage that displays the final result. Call this "A" Two sibling pages that don't reference each other but contain all the same contentplaceholder elements, just in a different order with different <div>'s surrounding them. Both reference the root-level masterpage. Call these "B1" and "B2". Several content pages that reference one or the other sibling master pages above (not both). Call these "C1" through "C-whatever".
Cn => B1 => A Cm => B2 => A
This hierarchy works fine. Desired Setup What I want to do is add in a new level to this hierarchy (a new master page) between the content pages and the sibling masterpages. Basically so it's like this: One root-level masterpage that displays the final result. Two sibling pages plus a third sibling. Call it B3 A new middle masterpage that dynamically 'chooses' one of the sibling masterpages. The desired behaviour is to pass through the content given by C directly to Bn without modifying it. The only thing D actively does is choose which Bn. Call this new masterpage D. Several content pages that reference the new middle master page instead of the old siblings. The challenge to this is, I'm working within the confines of a rather complex product and I cannot change the original two sibling masterpages (B1 and B2) or content pages (C) in any meaningful way.
I want:
Cn => D => B1 => A Cm => D => B2 => A Ck => D => B3 => A
Essentially, D should "pass through" all it's content to whichever B-level masterpage it chooses. I can't put this logic in the C-level pages. Additional Details All B-level pages have the same content/contentplaceholder tags, just ordered and styled differently. D can be as convoluted as it has to be, so long as it doesn't require modifying C or B. I'm using ASP.Net 2.0
masterpage with a contentPlacholder multiple pages which use this masterpage and implement a base-class (fooPage) fooPage has a certain property (fooProperty)
[Code]....
Obviously this is not going to work - but how can I achieve this?
I know the alternative: call a method from the masterPage in the contentPage with fooProperty as a parameter - but i would like to rather have a pull-system in this case...
This works fine when I display the page. However, when I click the language link which causes a postback the content block does not get added to the placeholder, so I get a null reference because those two panels don't exist. I've been pulling my hair out over this for a few hours now and I can't figure it out. In case it helps, here is my InitializeCutlture method:
I have an app that uses masterpages. On the masterPages I have a TreeView. I would like to only refresh the ContentPlaceHolder & not the Entire masterPage when a link is clicked on the treeView.
I have placed the contentplaceholder in an Updatepanel. I would like to if possible avoid including the menu in the update panel.
I'm trying to set the where clause on a LinqDataSource object bound to a GridView programmatically on a button click, but when the GridView rebinds data (for instance, when the user sorts) the Where clause resets back to the empty string. Is there a way to prevent this, or is there a better way to filter my results?
I've a DetailsView which I would like to pass an ID across to another page but cannot figure out how to do it!My ContenPlaceHolder is called MainContent, DetailsView is called DetailsView1This is what I have:
This is my Controller Action which takes a Page entity from database and shows it in the Show.aspx view using the "Site.Master" master page:
[Code]....
This is the "Show" view rendering "Page.Title" in the "MainContent" content placeholder:
[Code]....
And this is the "Site.Master"
[Code]....
Using this approach i can show "Page.Title" in Show.aspx using any master page that has a "MainContent" placeholder, but my real goal is if i can when i choose the MasterPage for that particular Page to also see a list of available ContentPlaceHolders and when i choose one to then render "Page.Title" in that particular ContentPlaceHolder.
I'd like to track how many visitors I get in each page on my website (entirely coded with .aspx pages). I'm not very familiar with ASP.NET, but I'm sure that it has an easier way to count each page's hits than putting code on each one of my .aspx pages. I assume that this "way" is using the MasterPage I already use. Am I wrong or correct?I'm using Visual Studio 2010. How shall I proceede?Just to put things clear: I'm using VB on my code and I'd like to store the information (number of visits) internally on server, not using a third party site.*cross posted here:http://social.msdn.microsoft.com/Forums/en-US/vsreportcontrols/thread/b1a8ec3d-3881-4da5-9e64-002601b72e68?prof=required
Can anyone point me to where i can find a documentation about css, masterpage and derived pages in VS2008. I used them in VS2005 but it looks like it's almost impossible on VS2008. or it's just me.
We have a master page file in which we have a MenuControl. We are displaying some menus according to users credentials. We are handling MenuItemDataBound event inside master page for adding & removing menus.
There is user edit page{ContentPage} on which user may edit his own credentials. After saving the edited data {users credentials} by ASP.Net Button control, the MasterPage's MenuItemDataBound event doesn't fire (in case of refresh it is firing but in case of post back it is not firing).
We need to recreate/refresh MenuItems for master pages after saving the user and add/remove any nodes from Menus.
If ispostback = false then dsDataSet = ..... END IF
Now I have a button where when clicked..
dsDataSet = anotherdataset...
Now I have 1 button that all what it does is loop through the dataset..
For each row in dsDataSet.tables(0).rows
Now the problem is that when I click on the last button, it says (cannot find table 0) which means the dataset is empty, why does the info in the dataset get removed on the postbacks? how can I avoid this?
In my masterpage, I have a menu that hosts an anchor. That anchor points to a another page and looks like this:
ASP.NET Code: <a href="../resources/techs/masterlist.aspx">BOMs & Service Manuals</a>
I used the designer to input the href location. This page and the "masterlist" page are using the same masterpage.
When I run default.aspx and click that link, it works no problem. But when I click that link from the masterlist page, it throws an exception because it can't find the file. Which makes sense, it's looking for "/resources/resources/techs/masterlist.aspx" because that page is already within that directory. I know how to format that link you point to itself no problem, but I can't figure out how to do it so that I don't have to manually change each page, nulling the purpose of the masterpage.
