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 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'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 2 user controls that is hosted by 2 different aspx pages.
example:
srcpage.aspx --> hosts the --> sourceusercontrol.ascx and destpage.aspx --> hosts the --> destinationusercontrol.ascx
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.
I am using flow player for my online tutorial site, which passes values dynamically. i.e. i am passing course id values, each id values having separate videos. Here is my code:
I am sending querystrin values over pages, but the problem space appear after some Valuse ,Here is the code I am using: aftre ("qud") value it adds a space i don't know from where,, so it gives error because it would be a fault value!
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 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??
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 chose the option to create a new ASP.NET Web Application (C#) project using VWD 2010 EXPRESS. Normally I choose the create an empty web site option. Anyways, It seems that everytime I needed to make a change in code behind that I would have to click save, then debug>build for the changes to take effect. This was working fine for three days, now all of a sudden it has stopped working. It doesnt seem to rebuild when I click build...though the output message says it succeeded.
I have even removed entire codeblocks from the codbehind (one that populated a dropdown), yet the drop down is still populated when the page is previewed (I have cleared the browser cache as well!). Also, I have tried to set Label1.text to various values and that does show either, like its not in the code.Is there a bug in VWD, or is there a setting I could have clicked unknowingly? I am gettingsome strange errors as well. For example, I am getting object reference not set to an instance of an object errors and the line it points to is a totally empty line
I'm using a 64bit dll (system.data.sqlite) in an Asp.net MVC app in VS 2010. The application runs and debugs fine, but all the aspx and ascx pages show errors when editing in Visual Studio 2010 and intellisense doesn't work. This is a VS2010 regression bug. Does anyone have a work around? (OR)Does anyone know of a free, reliable, production ready embeddable database that doesn't cause a 32/64 bit problem?More DetailsApparently this worked in Visual Studio 2008 and this has been is a known regression bug in Visual Studio 2010 for several months. I don't want to revert to VS 2008 and I don't want to debug in 32 bit mode.
I have web application that needs to debug and deploy as a 64 bit mode because it uses uses some unmanaged 64 bit dll's like system.data.sqlite. Also, I prefer debugging in 64 bit mode because it allows us to test some high memory use cases. After a lot of fiddling, Asp.net will deploy and run just fine. However all the aspx and ascx pages show errors and intellisense doesn't work when editing them in Visual Studio 2010. Apparently this worked in Visual Studio 2008 and this has been is a known problem in Visual Studio 2010 for months. I don't want to revert to VS 2008. There was a work around posted on SO here but it didn't work in my tests, limits debugging to 32bit mode, and also feels a bit hacky (I think it only works for VS Express style websites). Has anyone made this work in a web application or have a better work around?For those who are interested Visual Studio 2010 has two other problems with 64bit dlls that I have managed to work around.
Problem 1 - Cassini: Cassini can only debug in 32 bit modeSolution 1 - CassiniDev or Localhost: Debug using localhost or compile CassiniDev (an opensoure variant of cassini) in 64bit mode. I like the zero config simplicity of debugging a new web app with cassini so I used CassiniDev. You just stick the dlls in C:Program Files (x86)Common Filesmicrosoft sharedDevServer10.0 and it works (I recommended making a backup of the Cassini version you will be over writing).Problem 2 - MSTest: By default unit tests run with MSTest fail to load 64bit dlls.Solution 2 - AnyCPU & 64bit host process Instructions here, set local.testsettings to AnyCPU & 64bit host processI'm starting to think the whole setup is too little hacky and I'm on the verge of giving up and restructuring my application to not use a 64bit dll. I'm also really disappointed that Visual Studio 2010 caused all these problems. Can somebody make MS fix the regression bug they created?
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?
I'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; private string m_accountKey; private string m_siteKey; private string m_imUserName; /// <summary> /// Asp Table containing the filters /// </summary> public Table aspTable { get { return m_aspTable; } set { m_aspTable = aspTable; } } /// <summary> /// Report ID /// </summary> public int reportID { get { return m_reportID; } set { m_reportID = reportID; } } /// <summary> /// All the accounts selected /// </summary> public string accountKey { get { return m_accountKey; } set { m_accountKey = accountKey; } } /// <summary> /// All the sites selected /// </summary> public string siteKey { get { return m_siteKey; } set { m_siteKey = siteKey; } } /// <summary> /// 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.
How can I pass the result of the linq to a textbox?
Code: string search = txtSearchPO.Text; IPSBLL.TransactionInfo dbInfo = new IPSBLL.TransactionInfo(); var q = from info in dbInfo.GetTransactionInfo() where info.PONumber == search select info; txtPONumber.Text = q;
I need to access the column data something like this:
Code:
DataTable.Rows[index].columnName How can I do that in LINQ?
i have textbox whose value converted to Int32. while passing value to database when textbox is blank it gives error as Input string was not in a correct format.
In my app I'm using the AJAX modalPopupExtender on a panel. This works fine. The issue is in the code behind. I have this code in a LOOP: Panel.Show() I need the popup panel to show each time the code loops through. The issue is that it loops through the code then only shows the panel once at the end. Is there a way to have the panel popup through each pass of the loop?
