Web Forms :: Referencing Control On Another Page?
Feb 18, 2010
I thought this would be easy but i cant find what i am looking for online
I have 2 pages, the first 1 has a button that opens another page. On this 2nd page the user selects a picture. When the user selects a picture the form closes. When they select a picture i want the image control on the first page to change.
I'm not sure how to do this, i guess i could set the image path as a session variable and reload the first page but again i'm faced with the problem of how to reference the first page from the 2nd

I want to use a dropdownlist control as paging options (50, 100, 150, 200) for a GridView control so I can reuse the user control on other pages that uses paging.The dropdownlist control will be in the user control page and the GridView will be on the host page. How do I reference the GridView control generically from the dropdownlist in the user control to set the PageSize property of the GridView control upon selecting one of the dropdownlist options. Any advice and if there are other means to accomplish such tasks to allow reusability.

I have a label control on my MasterPage that is used to display error information. If an error occurs on another aspx page or a Module.vb page, how can I display the exception in the label control on my MasterPage? I tried using a Session variable, however, it would not work in my Module.vb code-behind file.

I have the following code which at the moment sits in a number of pages:
[Code]....
It sits in the page because I reference the usercontrol type 'emailSignUp' and pass data to an exposed variable 'DisplayType'. The control is located in the pages master page. Ideally what i'd like to do is put this in its own class or something, so I can just call it passing the configuration variable, but I'm unsure how this would work -

I have created a class within the App_Code called shared_methods.vb where I use methods that are frequently used within several pages.
I have a hyperlink control within the masterpage that i want to change the NavigateUrl depedning on what page. Just for better coding i would like to define the variable holding the hyperlink with my shared_method.vb.
I have:
Dim hl_back As HyperLink = CType(Master.FindControl("hl_master_back"), HyperLink)
This works within a page but not within shared_methods.

I am using a CustomValidator to compare two textbox control values in the form view. These values are not required but must be compared if a valuue is entered. The same two controls are defined in both Edit Item Template and Insert Item Template. The formview default mode is Edit.
The javascipt for the custom validator works when in Edit mode. However, when the form view is Insert, the javascript throws an error of NullReferenceException. how I can adjust my code so that the client-side javascript works for both Edit and Insert mode?
The form view is in a content page. The script is in the Head content placeholder
<script type="text/javascript">
<!--
function cvSecondaryEmail_Validate(source, args)

Basically I need multiple code-behind files each containing different functions for a page. Different classes do not do this because they are not connected to the page so their methods require parameters I want direct control of the page without the need for parameters.
I can only seem to crete one code-behind file and I need many. I've tried putting the aspx page in the App_Code folder but this causes an error.

My displaycloud.aspx page contains two databound data lists, each for displaying a tag cloud. The datalists have an EmptyDataTemplate that holds an empty label if nothing is retrieved from the db. I am trying to display the message 'Please Log a Story', by using the code below on the companyadmin page, but I am getting an error (the controls are not on the same page). How can I reference the labels positive_tags and negative_tags from displaycloud.aspx in companyadmin.aspx? Also, I want to redirect if the EmptyDataTemplate is not executed as shown at the very bottom of the page.displaycloud.aspx:
<EmptyDataTemplate>
<asp:Label ID="positive_tags" runat="server" Text=""></asp:Label>
</EmptyDataTemplate>

I have a Master Page that contains a Menu Control. Each menu item clicked is supposed to load a new aspx page. My problem is (since I'm new to Master Pages) actually loading a Content Page. This is what my MP code looks like and it's only just a snippet. The first set of code are the ContentPlaceHolders in my MP. The second set is the code in my code-behind file in my MP. Hope this makes sense. In the VB code, all I'm trying to do is load my Customer.aspx page. What am I missing?
HTML Code:
<asp:ContentPlaceholder ID="Welcome" runat="server"></asp:ContentPlaceholder>
<asp:ContentPlaceHolder ID="MainArea" runat="server"></asp:ContentPlaceHolder>
<asp:ContentPlaceHolder ID="CustContent" runat="server"></asp:ContentPlaceHolder>
Code:
Private Sub Menu1_MenuItemClick(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.MenuEventArgs) Handles Menu1.MenuItemClick
Try
Select Case e.Item.Value
Case "mnuCustomerMaintenance"
MainArea.Page = Customer
End Select
Catch ex As Exception
End Try
End Sub

I have a referencing problem in my project. I have an ASP.NET application where pages are in multiple subfolders. All pages user controls are working fine.
I just want to reference a page class that is not in the root folder (in subfolder from the root folder) in my usercontrol code-behind file like this
if (Page is ar_default){ //}Where ar_default is my page class name as it is in folder name "ar"The user control is also in the same subfolder as the page being accessed.Wnen I use the same method with pages in the root folder, there is no problem at all and it is working although I notice that the classes still not appearing in the coding drop down menu but if I typed the name correctly it work.like so:if (Page is _default){ //}When using the same code with classes in subfolders it is giving this error:The type or namespace name 'ar_default' could not be found (are you missing a using directive or an assembly reference?)I'm not using any namespaces also.

Working through Steven Sanderson's excellent Pro ASP.Net MVC Framework book.I am trying to reference the TempData collection to display a message after an item has been successfully updated and so have placed a reference to this on my Master Page.[Code]....
This is giving me the following compile time errors:
Error 1 The name 'TempData' does not exist in the current context <programme location>
Error 2 The name 'TempData' does not exist in the current context <programme location>
If I reference TempData on a content page it compiles (and works) fine.

Firstly, "Modifying" may be the wrong term, I see a few people have posted online just asking whether they can actually modify an embedded resource. What I am wanting to to, is use a resource in my assembly as a kind of template which I would do a find and replace on before registering it on the page - is this possible?
For example; say I have a few lines of jQuery as an embedded resource in my assembly and in this script I am referencing a CSS class name that can be set by the front-end programmer. Since I do not know what the CSS class will be until implementation, is there a way of going through the embedded resource and replacing, say, $myclass$ with ThisClassName.

Probably really easy but in my VB code I would like to say
If webpage = "ErrorPage" then
do seomthing
End if
So the thinking behind this is that if the ErrorPage is the open page on my site it feeds that into the webpage variable and then that runs the If statement.

I'm displaying a table based on query results, and each record has a dynamically generated dropdownlist and submit button (and other controls, but this is simplified). That part works fine, but how do I reference the controls in a function? Here is the code I've tried. Create the controls:
[Code]....
Reference the control values (hopefully):
[Code]....
The function SubmitAction_Click fires when I click the Post button, so that part works. I just can't figure out how to reference the selected value of the dropdownlist. You can see that I'm explicitly giving the DDL a unique ID (DS_RecordID). I'm guessing I have to use FindControl to reference it, but I don't know how to format the code.

I am using url routing to route user to his profile page. This profile page is a child page and is at the root directory. The css, javascripts are in css,js sub directories. Now the problem is of referencing in master page. All of the pages of the website runs smoothly except the page reached after url routing. This explains the problem i am having : [url]
I have used ResolveURL and URL.Content but this again shows up error saying me to missing an assembly directive. These are the other ways i tried in the master page:
<link rel="stylesheet" type="text/css" media="all" href="css/stylesheet.css" />
<link rel="stylesheet" type="text/css" media="all" href="/css/stylesheet.css" />
<link rel="stylesheet" type="text/css" media="all" href="../css/stylesheet.css" />
and
<script type="text/javascript" src="js/jquery-1.3.2.min.js"></script>
<script type="text/javascript" src="/js/jquery-1.3.2.min.js"></script>
<script type="text/javascript" src="../js/jquery-1.3.2.min.js"></script>
<script type="text/javascript" src="[Code]....
js/jquery-1.3.2.min.js"[Code]....
"></script>
<script type="text/javascript" src="[Code]....
js/jquery-1.3.2.min.js"[Code]....
"></script>
Or Is there anyway to redirect the user again as the usual site ran before url routing i.e.
on clicking the Home menu now the user is redirected to ...com/user/home.aspx whereas home.aspx is in the root domain. I am using this on the menu: <a id="A1" runat="server" href="~/Home.aspx">Home</a>
