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.
View 31 RepliesI 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 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>
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 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 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.
View 1 RepliesI have a content page which has a related master page.I register a prefix <%@ TagPrefix ..... and can load other custom controls at that namespace.However, one particualar control at the same namespace, when added to the aspx page, breaks it.The control in question inherits from asp:Panel, has a parameterless constructor, defines a few public accessors, and creates some standard child controls, and nothing much else.Are there some fundamental restrictions to creating custom asp controls that I am breaking unknowingly?

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?

<EmptyDataTemplate>
<asp:Label ID="positive_tags" runat="server" Text=""></asp:Label>

I have a series of dynamic controls that I'm adding to a page. These are listboxes.

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
