Pass Standard Information Between Masters / Pages In Code Behind?
Nov 14, 2010
I need my child pages to be able to set the values of certain properties of the Master page before loading. In other words, how my application builds the Master page for the client depends upon what properties are set by the child pages on the back-end. For example:
public partial class mstrPage : System.Web.UI.MasterPage
{
public int Rows { get; set; }
public int Cols { get; set; }
protected void Page_Load(object sender, EventArgs e)
{
/* Build a .NET two-dimensional-array of divs
that is <Rows> tall and <Cols> wide. */
}
}
In this example, the child page needs to set the values of <Rows> and <Cols> before Page_Load() is invoked for the Master. This is fairly simple to accomplish with inheritance in OOP, but ASP.NET web pages do not "inherit" their master pages in the code-behind. In the given example, what would the code-behind look like for the ASP.NET child page that sets these properties?
I'm using the inbuilt dot net authentication to register users in a simple web site and trying to add some extra information to be collected on registration. It currently asks for Usernname, email, password, confirm password. I'd like to add some extra bits, something like "favourite colour" - just a simple stringIs there an easy way of doing this? Maybe a simple tutorial I could follow?
I always create a folder "App_Pages" and use it ot put my aspx pages but I see with VS 2010 that it has several default folders created when adding a page. Which one is most applicable. Is it App_LocalResource? I assume that "App_Code" is where custom classes go.
we've started writing a standard toolkit for our asp.net applications including one standard master page, stylesheet, errorpage, noaccesspage etc. that will be used by all our applications. Is there a way we can add these pages to each individual application from one central location - so if any of these standard pages change, we only have to change them once and not numerous times in our individual projects?? I tried to build these pages into a standard .dll to no avail.
Page A loads very fast; Page B loads very slowly and does some CPU-intensive things on the web server. I noticed that if someone is loading Page B, then Page A also loads slowly - for ALL users. What is the standard practice for making sure this doesn't happen? If multiple users are loading Page B at the same time then Page A is ridiculously slow. Is there an IIS setting, web.config setting, or hardware configuration I could use to make sure that the fast-loading pages aren't bogged down by other pages that need more time to load?
what I want to do is, upon clicking a button on test.html, I want the getitem.aspx page to open in a new dialog and allow entry on a text box. After clicking the OK button on getitem.aspx, this dialog should close and the entry should be passed back to the html page.The issue is that the getitem.aspx has several buttons that trigger postback - but I only want the item from the text box to be sent back to test.html upon clicking of the OK button and not any other buttons.
Each row has a drop down, a text box and an "add" link. I'd like for someone to select something in the drop down, edit something in the text box and pass that information to an Action in the Controller.
I know i can do something like this:
[Code]....
[Code]....
Which is kind of gross - id like to do just call one action, that passes the selected drop down value, the textbox value and call just the one action, is it possible to do something like this:
[Code]....
Where i pass the Dropdownlist selection and the textbox value to my controller specifically
We have a handler to deal with .dat files.. everything is already setup and server is acknowledging the file type and doing its thing to handle it..
But the handler requires 1 bit of information along with the HTTP request which is a physical file path.. the file name it knows based on the file we call , but how can i pass a custom header along with the request so that the handler will use that when the request is made?
Basically when on our player.aspx page, i will have a button, when you click that button a request is made to the .dat file, but along with that request i need to send the physical file path.. how can i do that?
I was looking at using the Jquery request to call a second aspx page which either inserts or selects records from the database. My concern is the security of using Ajax. To pass information to the second page the Ajax request constructs a query string which is read from the second page. However, I don't know if I feel comfortable having the query string parameters so easily accessible. Especially if inserting records using Ajax anyone could follow the page being pointed to and then just load that into a new window with the query strings filled in.This would result in potentially a database attack adding many fake rows.Are there any security measures I can put in place to keep my Ajax secure or preferably hidden?
I'm looking for detailed technical information on the compilation process for aspx pages and vs2008.Recently I have been learning about controlbuilders and pageparserfilters. I have downloaded some code to clean out extra white spaces in my html in order to make the pages smaller. The code works great, but I don't understand WHY it works. I need to learn more about the page compilation process.
I m very new in VS (ASP.NET) and using C# in code behind file. I want to define global variables to use in whole application. EXAMPLE
I want to save some information in LOGIN Page and display it in other pages line UserName or AccessRights etc. Is there anyway to do this without using Cookies and Seassion ?
I have linkbutton on a Gridview located at one asp page and I need to pass the value of the link button to the page load of another page located in the same project. How can I do that?
I'm missing a the code browser when I create pages that have the code not placed in a seperate file. For pages with .asp.vb files I get the browser correctly.
I think it's called a code browser but just in case it's not I mean the dropdown that shows Page Events, Buttons and other controls that can be selected along with their events.
How do I turn on those dropdowns for pages with code behind that uses <script> tags in the actual .aspx page?
Included (Showing page events just under the tab):
I enabled the selection on my gridview. The question is, I can pass values with buttons but it seems redundant, because I have selection linkbuttons. So how can I pass variables with them ?
I have one application in which I want to pass data between Pages (Views) without sessions. Actually I want to apply some settings to all the pages using query string. For example if my link is like "http://example.com?data=test1", then I want to append this query string to all the link there after and if there is no query string then normal flow.
I was thinking if there is any way that if we get the query string in any link for the web application then some application level user specific property can be set which can be used for subsequent pages.
I have the beginnings or near endings of a data search web application. My first significant ASP.Net application. I understand how to do this in Calssic ASP but ASP.Net it quite different. I have 3 Pages:
What would the recommended method be for passing search parameters from page 1 to page 2 then to page 3 and back?
The challenge here is that on page 3, I allow paging through other records related to the record selected in a gridview on page 2. When done paging through these records on page 3, I want to return to page 2 with the same results and gridview page I left from on my way to page 3 originally.
I also may need to display the details on page 3 from some other source page.
These questions come up because I have: <%@ PreviousPageType VirtualPath="~/Default.aspx" %>
In page 2 that tells this page to get its values from public properties exposed in page 1 (Default.aspx)
Page 3 has: <%@ PreviousPageType VirtualPath="~/AssessSearchResults.aspx" %> to get public property values from page 2.
This is the start page: [URL] ....
I also have a very similar application in Classic ASP here: [URL] ....
I have one repeater control with check boxes in one of the page.My requirement is i have to pass the values of the row that i have checked (multiple check boxes can be selected at a time) when i click on a add button in the same page which is placed outside the repeater control.and, i want the details of the rows that i have selected to populate in another repeater control placed in a different page. how to do this using query string??
I've got a pretty simple problem but I am not sure what is the best way to accomplish this. I've got an input aspx where a user fills in about 15-20 input fields and I want to display this information on the next page however; I am not really sure what is the best way to go about doing this?
I tried using 'Server.Transfer' and 'FindControl' API calls but have struggled to use them because the value is always null because it cannot find the asp:textbox ID I have specified from the previous page.
What would be the best way to just simply transfer the values from my previous page to the next page??
i dont understand where is the problem with my code. i need to pass the request_id to another page but it is always passing the integer values as 0. whenever it comes to pass integer values it is passing it as 0 even if i perform conversion of string to int.
I have a <div> tag in html page in asp.net as shown below: <div id="DestAdd" runat="server"></div> The above tag store information like "Jurong West". The following code store the address in its innerHTML: document.getElementById("DestAdd").innerHTML = DestRoadName; I would like to retrieve the information "Jurong West" stored in the <div> tag in code-behind: string retdata = DestAdd.?
