I wish to place a sub in the code behind of my master page, that will be used to assign variables used in the content pages based on query string values. I would like to see advice on general syntax as it relates to the relationship between master pages and their content pages.I would much rather pursue this route as opposed to repeating the same code on every content page.

I have two master pages in my application(Suppose Master Page A and Master Page B). I have written a server side method in Master Page A.
How to access this method from code behind of Master Page B?
I have a master page called SiteMaster.master
The master page has a content place holder (ContentPlaceHolderID="MainContent")
I have a default page (default.aspx) with a VB code behind which pulls some data.
What I'd like to be able to do is write my data to that place holder for example:
<b>theData</b>
This is a simplified example of what I'll be doing but the part I can't figure out is how to write the content directly to the place holder on the master page from the code behind of the default the page.
i want to place a bulleted list with links inside a master page. the problem is that no matter what i do i get an error when i try to press on the link when the link directs me to a page that exists on another folder in my project. (i tried using the ~/some_folder/somewebform.aspx but it didn't work).
View 1 Repliesi put one label in Master Page,
i want to change that name according to the conditions.
i have another page HOme.aspx,in that i enter user name. that name should come in Master page lable for that what should i do.?
This is my scenario. I have a couple of content place holders on a Master page which by default are empty.Two of the content place holders are laid out side by side. I'll call one MainContent and the other SidebarContent. What I'd like to see happen is if a child page has content in the SidebarContent, the width of the MainContent should be adjusted accordingly.Is there a way to determine at runtime from the Master page if the calling child page has populated the SidebarContent?How do I go about this, if possible?
View 1 RepliesMy application has a Parent master page, a child master page and an aspx page( inheriting the child master page)

However i would like to know whether the aspx page can place contents inside the placeholder B( which was not used by child master page)

View 2 RepliesMy computer system froze on me, the mouse froze, cntrl-alt-del, did nothing, so I reset it. Did a disk check, and now everything seems fine except for my master Page html code which I was in the middle of editing when it happened. The VB code-behind file is still ok, the designer file still shows ok with all of the controls in it, but I can't get into desgn or source view. It just opens and gives a whole page of hesixecimal code such as as:
00000030 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
00000040 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
It just gives me a whole page full of numbers like this. I haven't backed up for a few weeks and so I hope I can get this back.
I have a nested master page that has its own master page. The parent master page has a property defined in its code behind.
Public ReadOnly Property SelectedPage() As String
Get
Return _selectedPage
End Get
End Property
How can I reference the parent master page's property from within either the child master page's code behind Page_Load or aspx template page?
I have a relatively simple page that will do most of its operations on the client side using Javascript or JQuery. However, initially I do need to retrieve some data from the DB server based on QueryString parameters.
I plan on passing this data in the form of a JSON string to the script by an old-fashioned ASP manner ( var severData = <%=MyPublicData %>) block where MyPublicData is defined in CodeBehind as:
Public string MyPublicData;
The question is, which event in the ASP.NET page lifecycle is the best for this? Page_Init ? Page_Load? Also, is it worth the effort to do this in ASP.NET MVC. I did look at this possiblity but it seemed a little too much for a simple page like this where I do more 90% of the work on the client.

View 1 Repliesim trying to do the following test:
i have one web page (test) and two masterpages (master_1 & master_2).
the test's masterpage is determined by querystring, so far it's working fine. both master pages have a set on links in content place holder area, but is it possible i can hide the content place holder where my links are, from one of the masterpage when my test page loads, because i don't wish to use the links in the masterpage for my test page. i don't want to delete the links either as i'll need them later on.
How to Create Master Page in Code Behind Dynamically?
View 1 RepliesMy hosting service is all messed up and my application keeps recycling. I am not able to figure out why my application is recycling. I am told that my application is using more than 100MB allocated memory but I just do not see what is wrong or how much is the optimized memory is required for my application.

if ((Request.Cookies["UserID"] != null)&&(Session["UserID"]!=null))

Some time ago I converted an old windows application to a web application. This web application works fine as a stand alone app. I was recently informed that my client had a new standard layout and they are using a master page. They sent me the master page.
The web application is quite basic in that it makes a number of calls to a web service to retreive a list of customer, retrieve list of products and allows customer to create an order containing products.
I did the following to get make use of master page:
Copied it to my solution Update the page directive to include the MasterPageFile attribute and set it to point to master pageAdded the relevant content areas to my page Copied my code (control declarations etc) into the relevant content areas.The application compiles correctly and renders as expected. However, it does not behave as expected.
For example, I display a list of customers in a GridView. The user can select a customer by clicking the select button that is present for each row in GridView. I do this once and select a customer the page is posted back and relevant row is selected. I select a different customer and the page it posted back but this time the selected row does not change. It is still shown as the first row i selected.
This functionality works as expected if i remove the master page attribute and content areas.
for some very special reason i want to click on a button in masterpage.aspx firing the event of code-behind without having reloaded masterpage.master.cs (starting page_load()).
