C# - Default LinkButton On Enter In A Master Page Cannot Work
Dec 7, 2010
I looked through and through and found no clean solution for this. A colleague of mine did find a pretty dirty solution but I don't see why the solutions in the links reference below does not work when I place it in a master page. I have a master page that basically has a textbox and a linkbutton, when I hit the enter key, the default button for the child page gets called instead.

I'm trying to build a master page. What I'm trying to do is have a header in the master page with login and register link buttons (which would change to username and sign out) and there are content pages like home.aspx, shoppingcart.aspx, checkout.aspx which would inherit the master page with that header. So in that process i wrote the following code in master page (First.Master). And i tried to inherit the master page in home.aspx through this following code Inherits="SampleMasterProject.First" in the page tag
<body>
<form id="form1" runat="server">
<div>
<asp:ContentPlaceHolder ID="Header" runat="server">
<asp:LinkButton ID="UserNameLinkBtn" Text="UserName" runat="server"></asp:LinkButton>
<asp:LinkButton ID="PwdLinkBtn" Text="Password" runat="server"></asp:LinkButton>
</asp:ContentPlaceHolder>
</div>
</form>
</body>
But I get following error
Content controls have to be top-level controls in a content page or a nested master page that references a master page.

I have created a master page for website layout in my project. I have used a linkbutton control to trigger between Login/Logout functionality but when I click on this control the underlying click event handler is not being executed anyway.When I click on this control, the page pointed by its PostBackUrl property is open which should probably occure after its click event hander have been executed.
[Code]....
and the LinkButton Control is

I have a page with several asp buttons defined on a Master Page. I only wish these buttons to be activated when they are selected by the mouse click. I have one button on the content of the form, that is the button I want to execute if the user hits enter and it is selected or they use the mouse. So in a nutshell. how do I stop the buttons on the master page from executing unless the user mouses them?

I have a master page that has a text box at the top with a couple of words in it. Below that I have a horizontal menu and below that there is the content place holder.I wish to set a default background color on the master page so that each other web page that uses this master page will inherit this background color.How do you do set a background color on the master page?I can't seem to select the background to set a default background color because the controls I have placed already.

I have a small part of my page existing on the master page. this small portion is embeded within an update panel that I postback using asynchronus postback. The problem is that; my default.aspx page which uses the master page gets affected (i.e I lost the text in the textboxes) on the asynchronus postback although the update panel doesn't include these textboxes. Is there a solution to ensure that postback only affects this part of the page?

we are upgrading the asp.net 2.0 web application to asp.net 4.0.
we have the many sub folders with default page (default.aspx)
and we are using the link like,
<domainname>.com/
<domainname>.com/folder1/
<domainname>.com/folder2/
<domainname>.com/folder3/
<domainname>.com/folder4/
it is working fine in asp.net 2.0
after the upgradation process, we didnt get above the URLs. i have checked site default page settings (in IIS "Document" default page settings), and default.aspx page is shows under settings.
the site url "<domainname>.com/" also does not working. if we call "<domainname>.com/default.aspx" then worlking.

I have the following placeholder in my main master page. I would like to not have to duplicate my news content in several content pages, so I choose to simply not provide this content in them, and the master page should provide its default.
<asp:ContentPlaceHolder ID="SideBarContent" runat="server">
<asp:GridView ID="newsGrid" runat="server" AutoGenerateColumns="false" Width="100%">
<Columns>
<asp:TemplateField>
<ItemTemplate>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
</asp:ContentPlaceHolder>
When I try the following code, I get an error because newsGrid is null. I assume I'm doing this at the wrong place in the page lifecycle, but I don't know where the right place is.
protected void Page_Load(object sender, EventArgs e)
{
Page.Header.DataBind();
if (!IsPostBack)
{
newsGrid.DataSource = _newsService.ListActive();
newsGrid.DataBind();
}
}

I've got a custom menu in the master page, that hides items according to different conditions (nothing to do with roles and perms). Is in the MasterPage.master file where i'm trying to hide them, e.g.:
[Code]....
The function isNormalMode() is defined in the code behind file MasterPage.master.cs, and everything is working properly in the page Default.aspx, but in the rest of the pages it doesn't execute the function at any time, so the item always remain visible.

I have very simple validation on the aspx page (highlighting not valid textbox), and it works perfectly. But when I try to work with this page using MasterPage, I've got an error - "Object reference not set to an instance of an object." (with reference to the line "aControl.BackColor=Drawing.Color.White" - underlined).
Here is the code of the content page.
<%@ Page Title="" Language="VB" MasterPageFile="~/MasterPage.master" CodeFile="testValid.aspx.vb" Inherits="testValid" %>

In my ASP.Net web application, I have a base page that implements functionality that spans all pages of the web application and my web pages derive from this base page. Since there is a single master page for the entire website, I don't want to attach the master page in each of the web pages. So I attached the Master page via the basepage's OnPreInit method as follows:
protected override void OnPreInit(EventArgs e)
{
this.MasterPageFile = "~/Site.master";
base.OnPreInit(e);
}
However, when I switch to Designer view, I get the "Master Page Error"; The page has controls that require a Master Page reference, but noe is specified. Correct the problem in Code View.When I run the application, the webpage shows up correctly.What should be done so that the designer shows up correctly without having to go and set the master page explicitly in each of the web pages?
BTW, I am on Visual Studio 2010 and .Net 4.0

This is my scenario. I have a couple of content place holders on a Master page which by default are empty.Two of the content place holders are laid out side by side. I'll call one MainContent and the other SidebarContent. What I'd like to see happen is if a child page has content in the SidebarContent, the width of the MainContent should be adjusted accordingly.Is there a way to determine at runtime from the Master page if the calling child page has populated the SidebarContent?How do I go about this, if possible?
