i have an odd thing with the Request.Params / Request.Form.i have a literal control in my masterpage.
[Code]....
So far pretty basic i thought. But to my suprise the geLocation turns out to be null. The control wasn't found...
when i then use a link from the dashboard page to another page which has the same masterpage, everything on that page seems to work fine.
I was attempting to use a gridview, but found that it was a little to restrictive in terms of formatting. So I'm using a DataReader and a StringBuilder (using the Append method to attach to the Literal control) to build a form. The form is pretty simple: labels, radio buttons, and textboxes. The appended data was practically taken from a classic asp page (with just some minor tweeking). For the most part there will always be 5 records on the form to loop through and save (sometimes less...never more).
Now comes the tricky part. I want to save the information on my form, but I'm not sure how to proceed. Do I use the Append method to add a save button to my form. And if so, how do I save the data (I couldn't use the codebehind could I)? Do I use an asp:Button and if so, will it recognize the form since it was build dynammically?
How can one Auto click a Literal Control button on Form Load?
View 4 RepliesTrying to output the PageName in a masterpage.
Masterpage has a Literal in which I am setting by accessing a property on the MasterPage "PageTitle".
<head runat="server">
<title><asp:Literal ID="litTitle" runat="server"/></title>
<asp:ContentPlaceHolder ID="head" runat="server" />
</head>
The child page is like this:
<asp:Content runat="server" ContentPlaceHolderID="content">
<%
MasterPage master = Master as MasterPage;
master.PageName = "Log in";
%>
</asp:Content>
And the property PageName is coded thusly:
private string _pageName;
public string PageName
{
get
{
return _pageName;
}
set
{
_pageName = value;
litTitle.Text = _pageName;
}
}
I'm guessing this is because the page output has already been rendered, but as I say I don't know enough about ASP.NET. I guess I'm after something similar to PHPs ob_start().
i have grid that uses around 12 to 15 label when i bind it...and grid contains thousands of records, now if i'll use literal control instead of label will it to improve the speed.
View 4 RepliesI'm using the MVC2 framework and one of my views has a bit of conditional logic that gets the Page.User.Identity object and does a comparison with other values to determine what to display.That all works fine on the initial page load, but when I make an AJAX call to get partial page updates (I'm doing this all manually with YUI3, not the .NET AJAX stuff) the Page.User object is always null.
View 1 RepliesIn my child page i have an imageButton, which is surrounded by the UpdatePanel. When the user clicks on the image button a record is removed from my database.
<asp:Content ID="Content1" ContentPlaceHolderID="Content" runat="server">
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<Triggers><asp:AsyncPostBackTrigger ControlID="btnRemove" /></Triggers>
<ContentTemplate>

In my master page i have literal control which displays the records for the current user (something like Records: 10)
The RecordsCount control is updated on the page Load event of the MasterPage
Private Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
RecordsCount.Text = GetRecordsCount()
End Sub
How can i update the RecordsCount control? I mean i use postbacks for removing records from the database. And currently the RecordsCount control will be updated if the user hits the Refresh button of the Internet browser. How could i apply the Jquery Highlight on the RecordsCount control when the user clicks on the btnRemove button on the child-page?
UPDATE: Well the first question is solved by using javascript
I am using BlogEngine.net and just created a theme (site.master) file and works but when I add a literal control and try to call a function from App_Code I get a 'Compiler Error Message: BC30002: Type 'basicFunctions' is not defined.' error. I call functions from basic_functions.vb in normal .aspx pages at the root. Since my error page is in a subfolder that has it's own App_Code folder, do I have to do something different?

i have a PayPal button, and i've been trying to add it to my site, but since my page is in a masterpage, and ovcourse, the form tag is editable only in masterpage, theres no way i could add the code inside the form tag, as so:
<form action="https://www.paypal.com/cgi-bin/webscr" method="post">
<input type="hidden" name="cmd" value="_s-xclick">
<input type="hidden" name="hosted_button_id" value="K92PCJ9ULE8LC">
<input type="image" src="https://www.paypal.com/en_GB/i/btn/btn_donate_LG.gif" border="0" name="submit" alt="PayPal - The safer, easier way to pay online.">
<img alt="" border="0" src="https://www.paypal.com/en_GB/i/scr/pixel.gif" width="1" height="1">
</form>
But as i tried to create another form tag, it came up saying i could only have 1 server side form tag.So is there any way i could do this?
I'm using HttpModule to capture requests to the web server. Before processing the page I'd like to check the values contained in some keys of the Request.Form collection and according to some logic change if necessary. I'd like to do this when BeginRequest event is fired. The problem is that the Request.Form collection is readonly.
View 4 RepliesI have a simple ASP.Net page, and I am enumerating through the controls doing things to the controls via reflection (localising the page - but that is whole other can of managerial dictat type worms). So...I have a test page thus:
<%@ Page Title="" Language="C#" MasterPageFile="~/Master Pages/Root.master" AutoEventWireup="true" CodeFile="refelectiontest.aspx.cs" Inherits="refelectiontest" %>
<asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">
<asp:Button ID="Button1" runat="server" Text="Button" />
[Code]....
Now, if I just run this, it barfs with an object null exception. And if I step through the code, putting a breakpoint on the control.ID line, then indeed the ID is null. However, if I then expand the control object, the ID fills itself out and all is well.
It looks like the ID is only getting completed at the last moment - how can I ensure that I can get the ID without getting null? The same thing happens if I don't use the master page.
Im dynamically generating an HTML Select Box, lets call it myselect. Im creating this select box based on some database values Im generating an HTML Select Box.. almost like a string that Im just spitting out to the page. So it's never a control in the codebehind, just part of a string thats rendered as HTML by the browser. If I submit my form, and in my codebehind I perform:
Dim myVal as String = Request.Form("myselect")
That code will give me the VALUE of the myselect select box. How can I refer to this control to cast it as a System.Web.UI.HtmlControls.HtmlSelect control? Request.Form seems to give me the value, but I want to reference the object itself..
I have a page that will display up to 4 videos at a time.. BUT i would like to see if there is any way to calculate and set the width and height according to the number of videos im presenting..
If only one video, i want it to take up the entire width and height of the space i have allocated.. ( say thats 1000w x 800h )
If im displaying 2 videos, then split that space up between the 2 and so on.. keeping the aspec ratio so not to distort the video window..
Right now im hard coding each one 400x300 which looks good when there are 4 laid out on the page.. just want to see how doable is this to accomplish..
My Request.Form keys are all prefixed with ctl00$container name$ and then the key I want.
How can I get the regular key name working?
Visual example from the immediate window:
I want to use:
? request.Form.Item("stationIdea")
but it won't work because the key is:
ctl00$content_innovation_body$stationIdea
as retrieved by
? request.Form.Keys("4")
so only this works:
? request.Form("ctl00$content_innovation_body$stationIdea")
I have a news list and when I click on every each news, it navigates to another page where I can see news details. What I need is I want to request every news title in news details page and show it in <title> section in <head> as the pages title. It means the <title> tag in news-details page must be dynamic and will change depending on every news articles title. But I don't know how to do this because the only parameter that will be sending from news-list page to news-details page is news-id and not news title.
View 1 RepliesI do some stuff with dynamic DropDownLists. A choice at one level makes the next level appear and so on.
When I open up an old report for editing, the first level is not editable so I set that DropDownList to Enabled=false (still dynamically in code).
My problem is that when I press save (a LinkButton) I first come to my OnInit as usual and check the Page.Request.Form for my DropDownLists, but then the first list is not represented.
But if I change one of the lists when editing, a postback is made, then there is no problem at all with the Page.Request.Form, the first list is there all the time.
Is there some fundamental difference with causing a PostBack from a LinkButton vs a Dynamically Added DropDownList?
I know that dynamic buttons and buttons in general don't use a typical postback and they post through the page.request.form. Okay, so in visual studio, I was able to determine that page.Request.form and in the all-keys property, i SEE my button there. It is the last item in all-keys.
When I am clicking this dynamic button which is in an updatepanel, the script below does not detect it as a button, it is still showing it as null:
public static Control GetPostBackControl(Page page)
{
Control control = null;
[Code]....
but here is the kicker, when I am traversing through the object, I am looking at the object C and the property 'ctl'. The ctl is showing me a value of "ButtonRow_0Col0" and it is of type string. This is good! But , the 'c' control object still says 'null'.
We're trying to implement functionality that intercepts, inspects, and alters if needed data in the Request.QueryString and Request.Form collections.
Since Request.QueryString and Request.Form are readonly, is it possible to use a HttpModule to do this without Reflection or Response.Redirect?
We're thinking that we can construct a new HttpRequest, and replace the original one. Would there be any implications in doing this?
I know mocking this object is impossible without using HttpRequestWrapper, but wasn't sure whether ASP.NET sets other things beyond the constructor.
This is a input
<input type="image" src="<%=Url.Content("~/images/shopping-cart.jpg")%>" alt="shopping cart" id="btnshoppingCart" name="btnshoppingCart" value="shoppingCart" />
when i browse the page with firefox and click on the input Request.Params["btnshoppingCart"] != null or Request.Form["btnshoppingCart"] != null is statisfied.
When i browse the same page with internet explorer 8 and click on the same input Request.Params["btnshoppingCart"] != null or Request.Form["btnshoppingCart"] != null is not satisfied. When i used the watch i saw that there is no key by the name of "btnshoppingCart" in either Request.Form or Request.Params if input is clicked from internet explorer. However when it is clicked from firefox there is value "shoppingCart" inside Request.Form and Request.Params against "btnshoppingCart" key. One more strange thing that i observed was that are two keys "btnshoppingCart.x" and "btnshoppingCart.y" inside both Request.Form and Request.Params whenver clicking is done from both internet explorer and firefox. This is happening against all inputs of type image irrespective if the input is present inside a html form or not. Forms are created like this
<% using (Html.BeginForm("Action", "Controller", FormMethod.Post)){%>
The version of internet explorer is 8.0 and firefox is 3.6.6
