The thing is the content doesn't change, only after I click on something else.If I skip through my code after clicking on the menuItem I can see that it passes the code and it should change, however for some reason the page needs another extra trigger to modify it's content.I also see the page reloading so I don't understand why it's not changing immediatly. I guess I'm not understanding the asp.net logic just quite yet.
I am building a website in which all of the site layout is in Master page and the content of the site is in the inherited pages. I have various links for navigation in which i simple use Response.Redirect to transfer to different pages. Now the problem is that I want to put the content place holder inside Ajax Update panel so that the postbacks are Asynchronous and I want to show the postback by an animated image inside Update Panel progress control. The problem is that I am unable to achieve this result and the entire page is posted back and rendered again. I have placed the content place holder inside the Ajax control toolkit's Update panel but it does not work. Is there any way that I can change the content of the content place holder to a new page with asynchronous postback.
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).
The master page lies in Root/MasterPages/masterpage.master
Now this image is displayed in a content page which is in Root/SomeDir/ContentPage.aspx, but it doesn't work in a content page which is in Root/SomeDir1/SomeDir2/ContentPage.aspx. Why?
Any idea why my web page content doesn't resize with the window?I'm not using fixed position - just a table with width="100%".I've put it in a placeholder
I have a master page with an unordered list that contains items like, Home, Messages etc.
Now I am working on an EditProfile.aspx page and I want the menu to change and have items like Basic Information, Profile Picture etc. Sort of like facebook. What is the best way to accomplish this...
<ul class="menu"> <li class="first" runat="server" id="Li2"> <a runat="server" id="A1" href="../NewEntry.aspx">Create a New Entry</a> </li> </ul> when i go to content page ("NewEntry.aspx") i want the link name to be changed to "Update Entry" <ul class="menu"> <li class="first" runat="server" id="Li2"> <a runat="server" id="A1" href="../UpdateEntry.aspx">Update Entry</a> </li> </ul>
i have a page called a1.aspx, with the Masterpagefile = a1_master.master. Now the master page has its own divs and images for design purposes. I want a way where when i load a1.aspx, certain chosen 's and images should be hidden(visible=false). how can i do this? how can i change the visibility of a div or an image in the master page from the content page?
I know I'm probably doing this wrong, but is this possible? I want to change a parameter of that control. It says 'inaccessible due to protection level'.
I have a text input to get a 'roomID' and an ASP button that calls an 'enterRoom' function:
[Code]....
In my head tags I have my enterRoom Sub:
[Code]....
Now when I click that button it essentially goes to the right page in all ways but the URL stays as my default.aspx instead of changing to users/room.aspx?roomID=23423. I've tried it in IE and Firefox with the same results. Is this something I'm not understanding about Server.Transfer or why is this happening and how do I fix it?
I have a master page and 5 content pages. I created another master page and want 2 of the content pages,which were under master1.master to master2.master.
For example, if the content page is called myhome.aspx, previously i had:
[Code]....
But the content page is still refering the Master1.master only..
How to change the content page to another master page.
I have 2 Imagebuttons on a nested Masterpage. When I click one button I want load a content page and change the image of the clicked button to show that it was selected. Loading the content page goes okay but I can't seem to programmically change the image of the button. I have been reading the posts on the life cycles of MasterPages and Content pages and I think I have the code in the correct page but it is not working. I am so confused now.
i have three master pages and some contents pages in my project.
in content page i have wrote below script:
[Code]....
And i have a language flags in my master page. so i have created image button for language flag to perform on click action. where On click of language flag (polish) i like to change the content (English) of my page as per the selected flag click.
hence i have wrote in master page:
<asp:ImageButton ID="ImageButton1" runat="server" ImageUrl="../common/images/pol.gif" AlternateText="Polish" /> And in code behind --- ImageButton1_Click Thread.CurrentThread.CurrentCulture = CultureInfo.CreateSpecificCulture("pl-PL") Thread.CurrentThread.CurrentUICulture = New CultureInfo("pl-PL") Response.Write(Thread.CurrentThread.CurrentCulture) Dim geturl As String geturl = Request.Url.ToString() Response.Redirect(geturl)
here the geturl is print with "pl-PL" but the page content is printed with English language.
I want to change page content also as per flag seletion.
Using VS 2010 RC, VB, I have a label on a masterpage that is hidden. I want to make it visible from a content page when needed, and have the text change on the label as well from the master page.
I am using the following to access the label, but the text and other properties don't change for some reason.
Dim lblErrorMessage As Label lblErrorMessage = CType(Master.FindControl("lblErrorMessage1"), Label) lblErrorMessage.Style.Add("display", "inline") lblErrorMessage.Text = "LoginID ALREADY EXISTS!!! Please choose a different ID"
I have a master page with a user control on it. How do I change the user control's properties from a content page?In my ascx file I created this 2 property:
I created some buttons and a label inside UpdatePanel. Upon clicking the buttons Label's text changes as configured. Lovely. Now how do I go about making a bigger piece of content change (without page refresh) using the same buttons? (Basically I'm trying to build Ajax tabs)I tried making the button click event change ContentPlaceHolderID value on some Content controls but that doesn't seem to work.
I have a pesky problem: if I change the UI culture dynamically and then I reload a page, the Resources.resx file selected was changed into the page but not into the Update Panel.
My project has the following repeater menu shown on the Master Page. I need this menu to remain hidden until the user logs in. How do I access from content page?
I'm using this Ajax script [URL] to load content from an aspx page on another server than the page calling the content. So far I've learned that this is a no go. The problem seems to be that when using an absolute link to content the script fails as apposed to using a relative link.
I've searched the web for about 10 hours now, and I still haven't found what I'm looking for.
Can I ask what this error refers to, (I have had it twice now over the last couple of days and then it goes away):
System.Web.HttpException: Content controls are allowed only in content page that references a master page.
This is followed by Stack Trace:
[HttpException (0x80004005): Content controls are allowed only in content page that references a master page.] System.Web.UI.MasterPage.CreateMaster(TemplateControl owner, HttpContext context, VirtualPath masterPageFile, IDictionary contentTemplateCollection) +9744256 System.Web.UI.Page.get_Master() +55 System.Web.UI.Page.ApplyMasterPage() +14 System.Web.UI.Page.PerformPreInit() +51 System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +1104
I am not using any Content Place Holder or Master Page (does the error refer to the Site.Master file because while I can see it in. Solution Explorer, I never use it. All of my aspx files look like this along the top with no reference to Site.Master:
