Web Forms :: Append CustomPrice To The Current Page's Query String Before The Response.Redirect Takes Place
Apr 25, 2010I have a page that is used to add info from a gridview into a user's profile. I have explained my issues after all of the code. Here is the applicable code(s) involved:
Protected Sub AddToCart(ByVal sender As Object, ByVal e As CommandEventArgs)
For Each gvr In GridViewItems.Rows
Dim txtGiftAmt As TextBox = (CType(gvr.FindControl("txtGiftAmt"), TextBox))
If txtGiftAmt.Visible = True Then
Dim customPrice As String = txtGiftAmt.Text.ToString
'HERE is where I would like to set the new price variable value somehow
End If
Next
Dim scart As New ShoppingCart
scart.AddCartItem(e.CommandArgument.ToString())
Response.Redirect("~/ShoppingCart.aspx")
End Sub
This sub is called by the following button when clicked:
[Code]....
Here is the sub from the ShoppongCart Class named AddCartItem:
[Code]....
Here is the problem that I am having: I have one specific item that allows user's to define their own price (for this item only). By putting this price in a session variable seems to be the easiest way to handle this (at least for me), but the session variable's value always "lags behind". By this I mean that the first time the items is entered, it uses the default value of cartItem.ItemPrice. The second time the same item is added (with the intention of a different price), this new item's cartItem.ItemPrice is set
as the first session("customPrice").
Because the user is selecting his/her own price for this item, I am not worried about lack of security involved with using query string to pass this price, but I can't get the string passed to the ShoppingCart class correctly (shows up null). Is there a way to append this customPrice to the current page's query string before the Response.Redirect takes place? If I understand this correctly, the Response portion "posts back" to the current page before the Redirect sends us on our merry way, right?

Web Forms :: How To Reference A Control On A Master Page From A Content Page Code-behind
Aug 5, 2010I am attempting to access a textbox control on a master page from a code behind base class but having problems.
I have 3 levels of master pages. m1.master is the master page for m2.master which is the master page for m3.master.
m3.master has a textbox as shown below
<%Master
Language="C#"
MasterPageFile="~/m2.master"
AutoEventWireup="true"
CodeFile="M3.master.cs"
Inherits="M3"
%>
<asp:Content
ID="Content5"
ContentPlaceHolderID="M2"

<asp:TextBox
ID="text1"
runat="server"
></asp:TextBox>
<asp:ContentPlaceHolder
ID="M3"
runat="Server"></asp:ContentPlaceHolder>
</asp:Content>
I have a content page c1.aspx that uses m3.master as its master page as shown below:
<%@
Page
Title=""
Language="C#"
MasterPageFile="~/m3.master"
AutoEventWireup="true"
CodeFile="c1.aspx.cs"

My content page codebehind class inherits from a base class BaseForm
public partial

The problem that i am having is that I cannot access the texbox from the class BaseForm. The BaseForm code is as follows:
using System;
using System.Collections.Generic;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

AJAX :: UpdatePanel Won't Append Data From Web Service To A Label Control
Apr 1, 2010I have an UpdatePanel with a button and a label. Inside the button click event I call a web service which returns a string. I then want to append that to the label. Simple! Except that it doesn't work. I can change the label to a value I set inside the click event but when I try to add the web service string it doesn't work.
I have been trying to override the PreRender event, to use a ViewState, to set EnableViewState on the Label to be false. Nothing. Works. At All. If I set a break point inside the OnPreRender override I can see that lbl1.Text is being set to the value that I want (i.e. the value from the web service) but it doesn't appear on the browser.

View 3 RepliesVS 2008 ITextSharp - Append Static PDF Page To PDF Generating
Jun 14, 2013This is the first time I've worked with itextsharp. I'm maintaining existing code so most of the work was already done for me. I have a question on how to do this enhancement.
My code currently dynamically generates a PDF with n-pages. I want to remove the code that generates the nth page and instead pull in a static PDF document. So in other words I have these variable data that I'm creating cells and tables from, but my last page is non-changing and we want to move from dynamically generating it to just pulling it in from an existing file.
I think this is the relevant code you would want to see:
Code:
// This method builds the PDF
byte[] bytes = (byte[])BuildPdf(startDT, endDT);
//Clear out the response
Response.Clear();
Response.ClearContent();
//clear out the headers
Response.ClearHeaders();
//add the new PDF headers
[Code] ...
BuildPDF() does all the work with the variably-occurring pages and ends with this:
Code:
// Add footer page
CreateFooterPage();
// Close the document to complete it
PDFDocument.Close();
stream.Flush();
stream.Position = 0;
[Code] ....
It is CreateFooterPage() that I want to change to just open an existing pdf, read it into some object and append it to this.PDFDocument. I know I am way oversimplifying it but simply stated, that's it.
Web Forms :: Why Master Control Page Code Behind Not Working
Mar 12, 2010My 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. So in my master page I am trying to capture if one of the session variables is null and redirect to login page in the master page.in my master page I have the following code:
if ((Request.Cookies["UserID"] != null)&&(Session["UserID"]!=null))
{
do something;
[code]...
Object reference not set to an instance of an object. referring to the session["UserID"] being null in the page where I thought the master page will handle the null value for the session before the page!
Web Forms :: Timer Control - Reload Page Every 60 Seconds But Change Url Query String Between 3 Values
Aug 27, 2010I am trying to get my head around the ASP timer control. What I am trying to achieve is to get a page to reload every 60 seconds but change the url querystring everytime between 3 values
i.e. scroll through
server/page.aspx?value=1
server/page.aspx?value=2
server/page.aspx?value=3
how I have though to do this is to use ASP code to grab the querystring value, and then create the next url. But I am having trouble passing that newly created url to a refresh control. im guessing HTML meta refresh is out of the question as I am using a variable. So from what I can see my option is to use the ASP timer control to count down (after the page has loaded) and after 60seconds load the next url.

AJAX :: Tab Control On A Page Which Add Via Code Behind?
Sep 21, 2010I have a Tab Control on a page which I add via Code Behind.I have a DropDownList on one of the tabs and I wish to add some Javascript to the DropDownList.With the Javascript I want to put some text 'blah' into a textbox when the DropDownList is changed. I try this ...
DropDownList ddlTR14TC2 = new
DropDownList();
ddlTR14TC2.Attributes.Add("onChange",
"javascript:alert('test - 1050');document.getElementByID('" + tbTR13TC2.ClientID + "').value = 'blah';alert('"
+ tbTR13TC2.ClientID + "');");
But it seems to think the tbTR13TC2.ClientID is tbTR13TC2 even though when I view the source it says it is 'ctl00_ctl14_g_3a30ee39_3359_4ab6_af81_8ef4e5b7316b_ctl05_ctl00_tbTR13TC2'
C# - Accessing Code Behind For A Control In A Master Page
Aug 12, 2010I need to display a control consistently across a set of pages. So I'm using a MasterPage to do that in ASP.NET/C#. However I also need to programmatically access this control, mostly provide options to view/hide depending on whether the controls checkbox is clicked.
Here is the Source for the MasterPage
<div id="verifyInitial" runat="server">
<asp:CheckBox ID="chkInitialVerify" runat="server"
oncheckedchanged="chkInitialVerify_CheckedChanged" />
I agree that my initial data is correct.
</div>
<div id="verifyContinuous" runat="server">
<asp:CheckBox ID="chkContinuousVerify" runat="server"
oncheckedchanged="chkContinuousVerify_CheckedChanged" />
I agree that my continuous data is correct
</div>
Now in the code behind I want to perform the following operations. Basically if a person clicks on the checkbox for the initial div box, then the initial box disappears and the continous box shows up. However it seems that the code behind for the MasterPage does not activate whenver I click on the checkbox. Is that just the way MasterPages are designed? I always thought you could do add some sort of control functionality beyond utilizing the Page Load on the Master Page.
protected void chkInitialVerify_CheckedChanged(object sender, EventArgs e)
{
verifyContinuous.Visible = true;
verifyInitial.Visible = false;
}
protected void chkContinuousVerify_CheckedChanged(object sender, EventArgs e)
{
verifyContinuous.Visible = false;
}

Code Behind Doesn't Recognize Control ID's On HTML Page
Feb 9, 2010I had a website with a few asp.net controls with id like:
btnSave and tbAmount
I renamed one of my controls and when I tried to use it in the code behind I get the following error.
Error 5 Name 'tbAmount' is not declared.
I was messing around trying to add new controlls rather than rename, but nothing seems to work.
And now, none of my controlls that were added to the page are recognized in the code behind. They all have the error:
Error 5 Name 'tbAmount' is not declared.
Or
Error 3 Name 'hfNoteId' is either not declared or not in the current
scope. E:NoteTenderNoteTenderMembersManageNote.aspx.vb 33 71 NoteTender
Even my button click event handler gives me the following error:
Error 2 Handles clause requires a WithEvents variable defined in the containing type or one of its base types. E:NoteTenderNoteTenderMembersManageNote.aspx.vb 27 91 NoteTender
I have verified that my inherits is using the correct namespace and class name.
