I have a master page containing a tree and 3 dropdown lists. I am populating a context menu on right click of each node, and when clicked on any item of the context menu, it navigates to required pages.
My problem is after navigating to the required page, the selected values from the drop down lists and the selected node from the tree are getting cleared.
I can set the selected values for the dropdown lists by making some properties in master page. But how do i maintain the selected node?
In my content page, i have got the valuepath of the right clicked node.
Or is there any other way than setting the properties in master page?
I'm trying to dynamically change the look of my main master page depending on what nested master page that the current content page is using .
So for example.
Main master page = main.master My nested page = nested.master (uses main.master) content page = content.aspx (uses nested.master)
So in the Page_Load event of main.master I want to add a switch statement that will check to see what nested master page is currently being used by content.aspx, or whatever content page is loaded.
So far I have got
protected void Page_Load(object sender, EventArgs e) { string nMaster = //This is the line of code that I am looking for. switch(master) { case "nested.master": //all my logic here. break; } }
I have a few pages in my web application where I would like to be able to use the code-behind of a master file, but not 'inherit' any of the other stuff like asp/html markup etc.
I need to display a control consistently across a set of pages. So I'm using a MasterPage to do that in ASP.NET/C#. However I also need to programmatically access this control, mostly provide options to view/hide depending on whether the controls checkbox is clicked.
Here is the Source for the MasterPage
<div id="verifyInitial" runat="server"> <asp:CheckBox ID="chkInitialVerify" runat="server" oncheckedchanged="chkInitialVerify_CheckedChanged" /> I agree that my initial data is correct. </div> <div id="verifyContinuous" runat="server"> <asp:CheckBox ID="chkContinuousVerify" runat="server" oncheckedchanged="chkContinuousVerify_CheckedChanged" /> I agree that my continuous data is correct </div>
Now in the code behind I want to perform the following operations. Basically if a person clicks on the checkbox for the initial div box, then the initial box disappears and the continous box shows up. However it seems that the code behind for the MasterPage does not activate whenver I click on the checkbox. Is that just the way MasterPages are designed? I always thought you could do add some sort of control functionality beyond utilizing the Page Load on the Master Page.
I got a Master page and nested master pages in the subfolders.
Top Level Master page
Second Level Master page inherited Top Level Master page
Third Level Master page inherited Second Level Master page
However, changes (i.e. new images & alt. name) that I made in the Top level master page did not apply to the second or third levels.My webpage has a correct front page but not in the sections. How can i correct this ?
I have a textbox and a button, and I trying to give the user a search option in the master page. The onClick event of my button is fine, but the textbox.Text property is always empty. I googled a little and fine many articles about accessing the Master from the ContentHolder, but I believe its no my case...
I want to add a class and initialize a JS funcion behind my nested masterpage which is being dervised from an other master page. But when I add the following code in the PageLoade event in the code behined of my derived page then it give the folowing error
Exception Details:
System.NullReferenceException: Object reference not set to an instance of an object.
here i wan to call nested master page from my base master page, can it work?
coz when i add new nested master page, it allow me to add and when i show in design of nested masterpage, it will link together,but how i make a button in master page to view the nested master page in master page's contain.
My computer system froze on me, the mouse froze, cntrl-alt-del, did nothing, so I reset it. Did a disk check, and now everything seems fine except for my master Page html code which I was in the middle of editing when it happened. The VB code-behind file is still ok, the designer file still shows ok with all of the controls in it, but I can't get into desgn or source view. It just opens and gives a whole page of hesixecimal code such as as:
I am using Master page and Content page combination.But how can i access <body> tag and it's event (onload, onunload) of Master page in .aspx page that is not a content page.
I've got a web site that has a master page and that master page (mpMaster that has a user control ucControl1) which has a sub user control (ucControl2), this user control has a property which accepts a value. Now, I have a page that uses the master page and on this page I have another user control (ucPageControl), I need to find a way of setting the value in ucControl2 from ucPageControl. Is this possible at all?
Can I modify the properties of a content page control from an event fired from the master page?create a delegate and event on master page wire up the master page in the content page create the event handler (function) on the content page modify for example:
contents of the Text property of a textbox render a control visible (or hidden) etc...
Following is the structure of the pages in application
[Code]....
Suppose the user is on ..../paycheck.aspx which is the content page. But when ...../paycheck.aspx loads, "lnkDynamic" properties "Text and PostBackUrl" must be set. Which events should be handled .....
On page load is there a way to enumerate all the nest user controls for that specific page load?
I'd like to be able to enumerate all the user controls that implement an interface, and call the interface method for the controls before asp.net passes control to thier page_load events.
The problem is from the master page level, any page in the app could be loading, and each of them could have any random user control, and I need the type reference to determine if they implement the interface, and to call the method.
All I want to do is access the <body> element from the code-behind of a content page and add a class name to it.
I have a top-level master page with the <body> element in it. Then I have a nested master page which is the master page for the content page. From the code behind of the content page I want to add a class name to the body element. That's all.
I have this in the top-level master:
<body id="bodyNode" runat="server">
I added this to the code-behind for the content page:
I am showing Custom Error in my page.. if somehting happend wrong. but if the same error occured in my subview master page I am not able to show the Custom error page on Entire page its showing me that Error page under subview master page. Please I am attaching the Screen shot. how to show the Error page on entire page if something happend in any where submaster or other page.. Here is the code that I am using in web config file to show custom Error page..
master page I have all the js files and Css files links and I have submaster page for mainmaster page.. sub master page have three tabs each tab has grid control.if something went wrong I can able to show the Custom Error page but its showing me in submaster page.. not in main master page.....but if something hapend any where I need to show CustoM Error page in main master page..
Here is my situation: I have a user control that has a menu in it. This user control sits on my master page. It is my main navigation menu for my application. I am having an issue where, on one of my pages, users seem to be leaving the page before committing all changes to the database, which results in a loss of data. So what I want to accomplish is - if the user is leaving this page and the data has not been saved yet, I want to prompt the user and say something like "The information is not yet saved, are you sure you want to leave this page" in a modal popup. So my approach is this: In my menu user control, create an event handler called MenuClicked that is raised when the menu web control's (in the user control) MenuItemClicked is raised, I raise my custom MenuClicked event. Then on my master page, I can catch this event in NavMenu_MenuClicked. My problem is - I need to catch this event in my content page, not the master? Am I approaching this correctly?
I come from a windows dev environment so the web makes me feel like a big dummy.
I am using VS2008, VB.NET, 3.5 Framework, ASP.NET, AjaxControlToolkit.
I have included a screen shot that might help to look at while you read my attempt to explain my issue below!
I just recently discovered in a book here on my desk how to interact with a master page programmatically from a nested master page or a regular aspx child page. The method they describe makes sense and is familar to me because they use Public Properties on the master page to manipulate the GUI and controls on the master page. But since they are public, the child pages can see them and fire them off. Makes sense.
I thought I could use this method to do the opposite of that and have the master page fire off something (say a public property in a nested page) to have it then do some work and update things on that nested page.
For example,
I have a MASTERPAGE.MASTER. Under that, I have a LEFTNAV.MASTER (so its a nested master page). Then, under that I have my default.aspx page.
(I did that so that for some of my regular aspx pages I could just tie them directly to the master page so that they dont have a left navigation page...like for big charts or graphs, etc. Is that the best way for that by the way?)
So on the masterpage, I have just a simple asp.net search textbox and an asp.net search button. When they type something in and click search, I want it to add a tab to the AJAXControlToolkit - TabPanel that I have on the default.aspx page, then some other things such as update a datagridview there with the search results.
I can do all of this except the event firing and scope. I cannot see a way to make a button on the master page up top fire off an event that is on the default.aspx page to make it do what it needs to do.
What I tried doing was creating a public property on my default.aspx page. I have some actual code in the SET to do some GUI manipulation and change some stuff on the page. But on my master page within the search button's click event, I cannot see where to call this public property on the default.aspx page...
I have a problem i am trying to work out the best method with my limited skills. Im using vb.net(VS 2010) I am using a dll for an IFrame , which is call from code behind. On my site I havea masterpage which has two gridviews. ( GrdViewWebBureau is the one i am using for this query) GrdViewWebBureau is contained within an update panel and updated on a timer control trigger. GrdViewWebBureau updates the page with file counts and status from our clients. I can click on any one of the cells and the code behind is fired. What I am trying to do is put an IFrame on the master page and every time a user clicks on the grid, the Iframe is fired up.
I have tested the iframe and vb code behind from a dummy page and it works, however when the Iframe is on the master page it doeant work. What I am tryingh to achieve is that no matter what page a user is on the site, they will be able to click on the GrdViewWebBureau and the iframe will fire with the correct childpage. Each webPage may also have an Iframe as well, so i dont know if it is possible to make the IFrame global and just call that control ?? I have no idea if 1 this is possible with the code i have and 2, if i have the brains to understand the who what why and when.
