View 3 Repliesi am trying here is to pass values to other pages. When i include the following code
private void Button1_Click(object sender, System.EventArgs e)
{
Response.Redirect("WebForm5.aspx?Name="+txtName.Text);
[code]...
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 ?
View 1 RepliesI 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:
(1)Search Parameters Page
(2)Results Page
(3)Details Page
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'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 would like the values in the text fields of the sourceusercontrol.ascx to be passed on to the labels in the destinationusercontrol.ascx.
I have gone through the MSDN ASP.Net examples and i was able to successfully pass values between two aspx page using the postback URL functionality, but cannot do the same thing with the usercontrols on 2 different aspx pages.

How to pass gridview particular column values to another page's table header...
View 1 RepliesI have an application that uses DataContracts/DataMembers and Serialization to store information entered in a tab control. There are 8 tabs in the control (therefore 8 aspx pages). The final tab is used to write the information to disk.I am trying to understand: When should serialization be used in a web app? The objects are stored in memory not on disk. Is this another means of passing objects between aspx pages? If so when should serialization be used vs. session objects? How long is the serialized object retained in memory?Can I get a simple example of how to serialize in one page and deserialize the object in another page?I've read many blogs regarding serialization but have yet to find a simple example and none of them explain when serialization should be used vs. session objects?

I have 2 Linq to Entity queries, here they are:
[Code]....
In "query" there are several columns, 2 of them are NIIN and Qty. In "objViewDDRT" there are only 2 columns, they are NIIN and AvailBalance.
What I need to do is for each row in "query" check to see if the NIIN is in "objViewDDRT", and if it is get the AvailBalance for that NIIN from objViewDDRT.
I'm currently writing an N-Tier architected ASP.NET system with a relatively normalised SQL database backend, but I'm struggling to get my head around how lookup values should be represented in my business objects (I don't get the priviledge of using EF or ORMs). My table (as an example) could be structured like this:
CoreDataTable:
ID | Name | Favourite_Colour
---|-------|-----------------
01 | Peter | 01
02 | John | 03
03 | Mary | 05
ColoursLookup:
ID | Colour | is_active
---|--------|----------
01 | Red | 1
02 | Green | 1
03 | Blue | 1
04 | Pink | 1
05 | Black | 1
Now initially, I had created my business object to look like this:
[code]....
I'm 100% convinced that I'm (a) overthinking this, and (b) making it more complicated than it needs to be. So, is there a preferred way of doing this? Or is there an option that I've overlooked?
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?
View 16 RepliesI'm building an MVC 2 RTM app, and I want to be able to share my model across applications. I'd *like* to be able to implement it like:ASP.NET MVC2 app (holds Views and Controllers)Class library to hold Model(s)WCF app to handle the data transactions with the models via different data stores across apps I had the MVC app working fine, but I wanted to abstract the data stuff and be able to work with the model across apps through the WCF site, so I created a class library project and moved all of the Models classes into that and set-up a WCF app, then added project references to the MVC and WCF apps that point at the class library. The idea was I can create services that take and return objects from the model via method calls across apps. It appears that everything's wired up correctly in the MVC project, so I'm passing the objects stored in the Models class library between controllers and views and everythig is compiling just fine, but for some reason the data is not being passed back from the views to the controller on POST -- all of the properties in the classes are null or empty.
When I debug the app, I can see that the values are stored in the model data dictionary but not the model object itself. What am I doing wrong? Am I on the wrong path, or missing something obvious (to some)?
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 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??
View 2 RepliesI 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've just finished and published my most recent version of
[URL]
but when I try to validate the website using http://validator.w3.org it is giving me few errors.
I noticed that I have multiple <title> tags in my pages and reason for that is because I am using master pages. What happened is my master pages are using <head> tag and <title> tag inside, then default page will have <asp:content ID="Content2" runat="server" contentplaceholderid="head"> and here I'll have another <title> tag.
The question is obviously I am having duplicate <title> tags across my entire website. Which <title> tags should I remove, the one in <head> tag of my master page, or the one on every other page such as one specified in default.aspx?
I would think that master page should not have the title and any other meta tags such as <meta name = "keywoards", "description" etc since I am repeating it in all other pages but is my thinking correct?
I am using an IFrame in one of my aspx pages. The source for the Iframe is an aspx page which consists of several links of other pages(All are developed in .net 2003) now i am using 2008.The Problem is for some of the pages there is query string which consists of username.I need to pass the username from the parent page to the IFrame pages.Is there any way to acheive this?
View 2 RepliesI've a requirement where i need to pass some objects across the pages. So i created a custom class with all the properties required and created a instance of it and assigned all the properties appropriately. I then put that object in the session and took it the other page. The problem is that even when i set the properties values to the class it is coming as null. I set a breakpoint in the getter-setter and saw that the value itself is coming as null.
public class GetDataSetForReports
{
private Table m_aspTable;
private int m_reportID;

public Table aspTable
{

m_aspTable = aspTable;
}
}

public int reportID

return m_reportID;

m_reportID = reportID;
}
}

public string accountKey

/// Current User Name
/// </summary>
public string imUserName
{
get
{
return m_imUserName;
}
set
{
m_imUserName = imUserName;
}
}
}
This is how i'm creating an instance in the page1 and trying to get it in the page2. Page1 Code
//Add the objects to the GetDataSetForReports Class
GetDataSetForReports oGetDSForReports = new GetDataSetForReports();
oGetDSForReports.aspTable = aspTable;
oGetDSForReports.reportID = iReportID;
oGetDSForReports.accountKey = AccountKey;
oGetDSForReports.siteKey = Sitekey;
oGetDSForReports.imUserName = this.imUserName.ToString();
But the values are not getting set at all. The values are not passing to the class (to the setter) at all. Am i making any OOP blunder?
I have an update panel with a gridview. When the user hovers over one field in the gridview, a HoverMenuExtender pops up to display more detail of the row from the gridview. The gridview also has a button, that when clicked, uses server.transfer to pass some info via the previous.page method about the row selected.
I can't get these two to work together. Either the update panel will work with the hover menu, or the button in the gridview will work with server.transfer. Sys.WebForms.PageRequestManagerParserErrorException is the error
Found this article that talke about using Response.Redirect instead of Server.Transfer. But, that won't work for me because Response.Redirect doesn't work with passing data between pages.

So, what I'm trying to do is figure out how to set a button in my gridview to be asynchronus, but can't figure out how to do that with this button from my gridview.

have some Objects, lets say Employee and Role defined as below and I have defined relationships in my database that gives me a list of objects say employees and thanks to my framework each employee object also has a Role object linked via the RoleIDID, UserName, Password, Email, RoleIDRoleID, RoleNameSo in code I can do something like this
Employee emp = dataService_GetEmployeeByID(1);
string RoleName = emp.Role.RoleName;
Now here is my problemI can bind any object in a repeater and it works fine for the first level in my relationship
For instance <%# Eval("UserName") %>
But I need to be able to show the details for my child objects as well (Role) so something like this (which does not work)
<%# Eval("Role.RoleName") %>
