Web Forms :: How To Change The CSS File Used In Master Page Dynamically
Oct 5, 2010
I am thinking that it would be better to use multipe CSS files and change them within the master page dynamically than it would be to use multiple master pages (basically one master page for each page, which defeats the purpose of the master page).
However, I do not know how to make a change to the master page before a standard apsx page that is derived from it is loaded.
I am working on masterPage/sub masterpages, all worked fine until this morning.When I open a .aspx which uses masterpages, in the design view it shows the error message..
I've checked both master pages several times, all tags are matched and visual stuido itself doesn't indicate any errors. Also in debug mode the html page is generated without any problems..
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 have a question about master page.After i pushed button i would like to change my master page to another master page for that page, is that possible?
I'm working on a project that have 3 diffrent type of users with 3 diffrent master pages. I can verfiy there access level and let them view pages but after googling I came accross a tutorial form asp.net but it wasn't very helpfull the code I got listed below works only if the session is at null, It dosen't seem to pull the session value.

there is a class page attached to it but nothing seems to work. I've downloaded the tutorial but it wasn't any clearer than what I read.
I 'm just trying not to have to code over the joint pages.
I have a web site with a navigation bar on the left side that uses image buttons to select the page you want to see. Each button has 3 possible images - the normal image when the page is not selected, the mouseover image when the the mouse is over the button, and the selected image when the button has been clicked and the page selected. Formerly each web page had its own navigation bar but I have moved the common content into a master page.
The problem I have is how to make the button image of the selected page to be the "selected" image rather than the "normal" image. Basically I need to change the imagebutton source to the "selected" image when a button is clicked and reset it to the normal image when a different button is clicked.
Currently the Javascript looks like this:
var loaded = new Array(); function F_loadRollover(image,imageName) { if (image && image.src && (null == image.out || typeof(image.out) == typeof(void(0)))) { s = image.src;
[Code]....
How can I tweak the Javascript so that the src of the clicked image is "content1_selected" instead of "content1_normal" and then reset it when another button is clicked. This seems like it would be a common need when moving a navigation bar to a master page to eliminate redundant code.

My requirement is to disable a control on Master page when user is on some specific step of asp:wizard control. I am facing 2 challenges,
1. I am not able to disable the control master page by setting its Enabled property as false, this is inspite that I am getting the control object when I do a Master.FindControl("MyControlName").
2. To try and disable the control from JS, I am not able to find a JS event that would get called when a speific tab step get active and loaded.
I would like to change the link that has been clicked, to class="active". I would like to add a class to the div if the page above is clicked too.

I have a master page 'Master1' and i have used a content place holder 'content1' and loads pages 'Page1' and 'page2' in the 'content1'. Is there any way to identify which page is loaded to the content place holder whether it is 'Page1' or 'Page2' dynamically.
I am looking for a method of centralising the lines that need changing in the web.configs into a master file. I know you can do this within app.settings using the "file=" attribute of the appSettings section... but is there a way to do this with the other settings without changes to code?The connection string is another example. I could ask the developers to recode any of these variables into app.settings, but there are things suchs as these that I dont think are editable.

I'm building an ASP.Net project that will require the dynamic creation and printing of images. I've been asked to "hide" the header information (which is contained in a master page) when the page is printed. Is this some sort of a property that can be changed when the screen is printing?
The print event is actually running on the client side:
