I need to get the list of ContentPlaceHolders of a MasterPage, but the property
protected internal IList ContentPlaceHolders { get; }
is protected internal, so we can't access them.
Is there any way we could pull them up from the MasterPage (including Reflection)?
I am new to Masterpages and thought I would set up some buttons on the left and right side of a masterpage and leave the center open for a ContentPlaceHolder for the stuff I would do in other pages.Is this possible?
View 2 RepliesI'm looking for a way to dynamically load a master page in order to get a collection of ContentPlaceHolders within. I would prefer not to have to load a page object to assign the master page to before I can access it's controls, but if that's the only way I'll be happy to use it. This is the way I was hoping it would work:
Page page = new Page();
page.MasterPageFile = "~/home.master";
foreach (Control control in page.Master.Controls)
{
if (control.GetType() == typeof(ContentPlaceHolder))
{
// add placeholder id to collection
}
}
But page.Master throws a null reference exception. It only seems to load at some point when an actual page has been created in the page lifecycle. I even thought of dynamically changing the current page's MasterPageFile on Page_Init(), reading all ContentPlaceHolders then assigning the original MasterPageFile back, but that would be horrible!
Is there a way to load a master page into memory independent of an actual page so that I can access properties of it? My final resort will probably involve parsing the master page contents for ContentPlaceHolders instead, which isn't as elegant but might be a bit faster.
How do I modify the Text of a label control in one ContentPlaceHolder based on another control situated in another ContentPlaceHolder please?

How can I write this with a masterpage
View 2 RepliesI tried to use user.identity.name in a master page code behing but intellisense doesn't recognize it.
If I change Inherits masterpage to inherit page then intellisense accepts it. What's going On?
I have a master page(created for pop ups as i have a lot..) with the following code:
<body>
<div id = "weadas>
content content content..
<div>
<script type="text/javascript">
var content = document.getElementById("weadas");
window.resizeTo(content.offsetWidth + 50, content.offsetHeight + 50);
</script>
</body>
Wich i call with the following linkbutton:
lbnDictionary.Attributes.Add
(
"onclick",
"window.open('../ijSistema/ijPopUp/ppUpDictionary.aspx','mywindow','width=auto,height=auto,toolbar=no,location=no,directories=no,status=no,menubar=no,scrollbars=no,copyhistory=no,resizable=no'); return false;"
but then it does not resize properly when poping up. It does work in IE6 but it does not in IE8 nor Mozilla 3.0.
Any ideas of how to optimize that resizing code for asp.net?
I have a some javascript code that I only want to run in one child page but it needs to be in the head tag to function correctly.
<script type='text/javascript' src=[URL] ></script>
<script type='text/javascript' src=[URL]></script>
<script type='text/javascript' src='lightview/lightview.js'></script>
<link rel="stylesheet" type="text/css" href="lightview/lightview.css" />
end code
Can anyone tell me how to do this? I cannot put it straight into the master page as it conflict with some other javascript code that I am running on a different page! And I cannot put it into the body of the child page because it does not function correctly.
I am struggling with something that I guess should be standard practice really. I have a number of user controls that use some JQuery plugins. I do not really want to link to the extra CSS and JS files from my main masterpage as this would cause extra load to the user the first time they hit the site, (admittedly it would only be the once), so I was just putting them links into the top of the user control. Then I looked at my source HTML, not nice! Even worse for controls that repeat multiple times on a page.
So I was thinking is there a way of injecting them into the Head of the page when they are needed from the User Control. For that matter is there a way of doing it to the footer for JS stuff?
I created a sitemap with a treeview navigation in my aspx site. I am hoping someone can show me the code to put in a Masterpage so that when I expand a child node, all other nodes collapse, and when I expand another node, the previous expanded node collapses.

I inherited an application written for VB.Net and am converting it over to ASP.Net, with VB as the back end. I have a data pull that adds values to a new instance of a class, then adds the item to a listbox. It worked great in the VB.Net version, but I get the following error in the Visual Studio Text Editor when I try to use the code:
Overload resolution failed because no accessible 'Add' can be called with these arguments:
'Public Sub Add(Item As System.Web.UI.WebControls.ListItem)':Value of type 'MyItem' cannot be converted to System.Web.UI.WebControls.ListItem'.
'Public Sub Add(Item as String)':Value of type 'MyItem' cannot be converted to String.
I have played around with the code quite a bit and have been researching online, but I'm just drawing a blank here.
I put the class("MyItem") in the "App_Code" folder in a file called "MyItem.vb". The class code is as follows:

The code I have for the sub that is supposed to add the items to the listbox is as follows:
