Passing Value To A Different Page This Way .. Error
Mar 23, 2011
I was reading the article http://www.dotnetbips.com/articles/c585b4d3-93c5-4c66-9d49-8e1946f4d311.aspx it mentions different ways of passing data b/w pages and one of the methods it suggested was
public string Name{get{return TextBox1.Text;}}Now call the server.transferprivate void Button1_Click(object sender, System.EventArgs e){Server.Transfer("anotherwebform.aspx");}On the destination pageprivate void Page_Load(object sender, System.EventArgs e){//create instance of source web formWebForm1 wf1;//get reference to current handler instancewf1=(WebForm1)Context.Handler;Label1.Text=wf1.Name;}Now i tried to replicate that my first page is Default and second is Default2.aspxinserted this in my Daefault public string Namer { get { return "sOME string"; } }and in Default2.aspxprotected void Page_Load(object sender, EventArgs e) { Default2 wf1; //get reference to current handler instance wf1 = (Default2)Context.Handler; Response.Write(wf1.Namer); ///The problem is Namer does not exist ?? }Why cant it find namer(I strongly doubt it could ??) could you make another webform a baseclass ?? what does contexthandler do ?? Why cant i make this example work ??
VS2010/VB/ASP.NET 4.0 If an error occurs in an ASP app you can redirect it to a default page which is defined in the web.config file How can you pass the variables (URL) to the error webpage then to a logfile or sent via an e-mail address?
Example: 404 Error
- Page hosting the link - URL - Search (if applicable)

I have a data driven asp.net website with frames on the top, left, right and center screen. If a page generates an error on any of the frames, I want to redirect the whole site back to the Default.aspx. Currently, when a frame page errors in one of the frames, that frame gets the error pages. Site is URL.... Is this something that can be handled?

I need to force SSL when going to the final checkout page (for example from default.aspx to checkout.aspx).
I need to pass variables to this check out page and tried to use server.transfer(https://www.mydomain.com/checkout.aspx). I then use previous page .Fincontrol to read text box and label name to this check out page. If I only do the server.transfer("~/checkout.aspx") then my I can read all vakues of my controls from the passing default.aspx page.
But when I force https:// then I cannot read the control values from default.aspx page.
Please give me some tips on how to get control values to the https:// destination page or if you have another tips on how to do it the right way, please let me know.
I have a FileUpload control in the Source page. On the Upload button handler, I read the file into memory (after doing some validations) and since it's always going to be a TXT file, I create a string that I need to pass to the Destination page. I thought of using Cross Page postback and set the PostBackUrl property of the upload button. But it appears that the breakpoint in the Upload button handler is never hit. It directly goes to the Page_Load in the Destination page. If I can't use Cross Page postback and don't want to use Session or the database, how do I pass this string from Source page to the Destination page?
I would like to take a value from a text box and pass it as a search parameter to my database. I get the value from my code behind page as follows: protected void btn_click(Object sender, ImageClickEventArgs e)
I need to access a variable that is declared in a master page to a child page. I'm using asp.net 2.0 (vb). I'm sure this should be easy and is down to my inexperience with asp.net! A rough guide to my code is below;
MASTER PAGE <%@ Master Language="VB" CodeFile="MasterPage.master.vb" Inherits="MasterPage" %> <script runat="server"> Public UserNumber As Integer = 3 End Sub </script> CHILD PAGE <%@ Master Language="VB" CodeFile="MasterPage.master.vb" Inherits="MasterPage" %>
I'd like to pass data from one asp.net page to another. I've seen that using System.Web.Caching.Cache is a good way to accomplish this. I'm wondering if it's a good way to do it and also is there any cleanup or other things I need to keep in mind when you the Cache?
I am using query string to pass values from page 1(log in page) to page 2 and then page 3. I have an .ascx file also, so how can I import the user name from Page1(login.aspx) to menu.ascx file. So that when I click the menu Home the value of the variable remains at the website. I am not aware of session handling thats why I am using this method to pass the valus among the various pages in website.
have a question about passing a gridview to a second page. I'm filling the gridview in the first page and by clicking a button,it's directed to second page and I want to see this gridview on second page.Must I have to convert grid to datatable or is there any possible solution? I tried converting from grid to datatable
DataTable dt = new DataTable(); dt.Columns.Add("urunAdi"); for (int i = 0; i < grdSepet.Rows.Count; i++)
I have a listbox containing a list of the datas In the child page. Now, if a user selects a multiple number of the items of the listbox, i have to pass all of them through the session.
So, i want to create an array in the child page and pass the values in the session and in the form of an array to the parent page.
In the parent page i'm displaying all the user details and one of the detail is the list of accessible clients in a list box. the clients can be removed or added using the add or remove images next to the list box.
Clicking on the Add image will show you the list of available clients in a new page(child) and also showing currently available clients to the user with checked status.
Let me explain how the available clients for the user is displayed in the child page. In the parent page load on the 'Add' image 'OnClientClick' i'm passing the ClientId of a hidden field in which all the selected clients for a user is stored.
The problem i'm facing here is when i altered the selected clients in the child page and clicking on the OK button will change the value of the listbox in parent page using the clientID of the listbox which i'm passing, but if i once again click the 'Add' button it shows the original values which is stored at the time of parent page load. The problem is i'm not doing any postback here so that the original values registered during 'OnClientClick'of 'Add' button is not altered.
When I add an update command to my page and run the page I get this error message
Server Error in '/MYApplication.
Incorrect syntax near '-'.Must declare the scalar variable "@recnum".
Description:An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

I have built a blog that sees the index on the master page and the blog pages within in the ContentPlaceHolder of the master page. The Blog pages use SQLDatasource control with the QueryStringParameter to pull the selection from the address bar.
My question is there any other way to communicate between master and content page, rather than query string (with out using cookies, or sessions)?
I have a need to put a search field (text box) on the master page to search the contents of the blog pages, I would like to use the controlparameter of the sqldatasource on the blog page, but I have not idea how to do this ? What can be done to allow a textbox on master page and SQLDatasource talk to each other in this manner ?
is the query string passing my only option btw master and content?
Looking for advice on passing variables from page to page without using QueryString. The web crawlers such as google get caught up on the querystrings found in a URL. I'm trying to get away from using it. Is there another suggested method for passing the variables? I've thought about using session variables, but this is just for simply passing the variable from page to page and they won't always be the same.
On another note, I can't do it using forms. I'm using a master page with a form embedded in the master page and also the content pages. Unless microsoft updated it so you can multiple forms on one page.
I have a web page that contains a GridView which the user is allowed to "Edit", "Delete" and "Select" rows. What I'm trying to accomplish is when a user clicks on "Edit", they are redirected to another web page that contains a DetailsView of the record they selected from the GridView (previous page). How do I make the association?

Because of a restriction on our analytics software, we need to pass all calls to external weblinks through a page - direct clicks to external links don't get recorded.Our classic asp page was simple. We had a link to out.asp?urlname and the out.asp did a redirect. I'm trying to emulate this in MVC without success.On the homecontroller, I've got an action:
Function externalLink(Byval id as string) as ActionResult Return RedirectToRoute(id) End Function
I thought I was close with the following actionLink:
<%=Html.ActionLink("more info at HMRC", "externalLink", "Home", New With {.id = "www.hmrc.org.uk"}, DBNull.Value)%>
But the URL that is formed is /Home/externalLink/www.hmrc.org.uk .I've had a route in mapRoute, but taken it out as it didn't affect things. I've tried replacing .id with a paramater name like .url so the url becomes Home/externalLink?url=www.hmrc.org.uk but the problem is really that it can't find the resource
Requested URL: /Home/externalLink
It does seem like a simple thing, but I guess I need to step away for a few hours and look at it again with fresh eyes - Sunday working wearing me out!
