Referencing A MasterPage Control From Another Web Page?

Nov 2, 2010

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 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)

Web Forms :: URL Routing And Relative Referencing With Masterpage

Jan 3, 2011

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>

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 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?

Referencing Content From Master Page?

Mar 19, 2011

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

Forms Data Controls :: Referencing Control In Javascript For Both EditItem And InsertItem?

Jan 3, 2011

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">
<!--
&nbsp;&nbsp;&nbsp; function cvSecondaryEmail_Validate(source, args)
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; {
