Web Forms :: Dynamically Change The Head Of A Webpage?
Aug 18, 2010
I've never had to dynamically change the head of a webpage before and can't quite seem to get it. As mentioned in the title, the webpage is the child of a very simple master page. Here's what i've got:
When the asp:menu object gets rendered, the parent nodes show up with an arrow head next to them.The arrow head's color is black.How can I change this to some other color?
I have several hundred html files that I want to remove the <head></head> tag from and all information contained in the tag. I am fairly sure I can do this in Visual Studio using the Find and Replace In Files with REGEX.
What I am trying to do here is I want to add the dynamically created labels in the Panel on the Webpage and not directly on the Webpage. My panel has scroll bars and thus when I scroll horizontally or vertically only the background moves whereas the labels are static to the page. And some labels are even visible on the panel borders on scrollbars (some on the page outside the panel) which are suppose to be placed inside the Panel. So when I scroll either of the ways even the labels should move along with the background image. So how can I make these labels stick to the Panel and not the Page? How do I do it?
In my one asp.net web page by VS 2008 I dynamically creates a set of RadioButtonList and TextBox by objects
[code]
The current issue is I can load the web page with a set of RadioButtonLists and TextBoxs but can't find the these dynamically built controls by Me.FindControl("rdoTask" & ID) in aspx.vb file to save info assigned to these controls.
how to load user control dynamically on asp.net page? I am loading user control in my page_Init() event under if(!IsPostBack) but when user post the with any button click then my user control is disapper?
If i am loading control without if(!IsPostBAck) then its fine, but each time a page is posted loading of control is not good because it will slow my web site?
I came to know that we can pass values from one page to another. What I wanted was 'on click of a button on admin.aspx webpage , the button on user.aspx page gets invisible'
After creating the instance and trying to do so, the error occured which said-"due to security the button cannot be accessed on user.aspx from admin.aspx"
Even if all the above what I did was wrong, I request you to suggest me how can I change the property of a button on webform1 from webform2 ( this is the admin.aspx page in which i have logged in) to invisible. And whosoever accesses the webform1 gets the same property (i.e. invisible) untill i click on the button in webform2 that again turns the property of the button in webform1 as visible.
I now that I can just define the width and height of a page with the div tag to allow for dragpanels to work, but it messes things up with some browsers when rendering, sometimes shrinking the actual content to allow for the complete page and width to be shown such as on the IPAD. I have tried the Javascript below, but it doesn't work, and whenever I try to resize a page manually, it puts my computer into never never land.
Anyone have a clean Javascript that will change the width and height dynamically as I am moving a dragpanel.
I can move the dragpanel, but it snaps back as soon as I let go so in essense it doesn't work.
How can one dynamically add Keywords & Title to a page. I had created one table called Meta table for URL rewritting in which in addition to url details, i had stored keywords & title of Product page. I had done URL Rewriting of the page but I just couldn't make out how can one associate a Product page with Keywords & title at runtime.
I am working for a project on disaster management sponsered by World Bank, under this project i have assigned work on CMS. and my senior has asked me to make a ASP.NET webpage where those logged with administrator privilege will be able to edit the page.
now if if the admin clicks on mydiv he should be able to edit the pre contents.
for this i got many options such as WYSIWYG editors (but they work on textboxs only and further more they cant save the data back to server replacing the previous content) then I came to know about Webparts , but its editing capabilities was so low that my plan for implementing a WYSIWYG editor went in vain.
i have pics in my website in differnt pages with width and height set to 320*320 px how can change this images in admin section to be replace by new one and with the same size. i m using file concept of storing the images
I'd like to have a standard sql select statement that depending on user input changes to alternative one.
I've written code similar to this:
if (something is true....)
{ SQLdataSRC1.SelectCommand = "Select *... etc";
// where SQLdataSRC1 is the name of the sql select statement datasource in the front end code. }
I've put this code in the onload event and in the SQL datasource event handler but still it gets ignored - and only the SQL select statement in the front end code is recognised.
I currently have a working menu driven by a sitemap.I would like to change one of the sitemapnode when a user hits one of my pages. How do i achieve this? I just need to change of the url for one of the nodes in the sitemap.
I've mad a function, that has a result of 24 rows.So the first row is LE1, the second LE2, the third LE3 ......But how can i programmically change the row.LE1 ? It should be LE + i ...Take a look at the code:
I have a page that contains radioButtons. Each click on a radio button loads a user control (.ascx) in the page.
What I am doing is loading all controls at the same time, but set their visibility to false. When a user clicks a radiobutton I set the visibility of the specific user control to true.
As a result I am loading all the user controls on each postback.
I tried passing in the name of the file via querstrying but it looks like flowplayer wants to load it before the Request.Querstring["videoName"] value is retrieved.
I would like to create a category page in the admin section where the admin can create/add category from the webpage , he/she don't have to go to database to create it how to make this possible by sourcecode in webpage and in database?
In my website I have <img src from code behind (created the whole table and css in the code behind). So for an image I added as <img src='../combox/img/products/prod1.gif">
So when I run this page and see the view source, I get the following path for my image: <img src = "http://localweb1/combox/img/products/prod1.gif">. Here localweb1 is my development server.
But I want to change this "http://localweb1" to "http://www.mypage.com/ so the img src will show as <img src="http://aeroprod.com/combox/img/products/prod1.gif">
How should I do this in my code? Do I have to parse? In this case how do I do it?
I have created an aspx page that is displaying user profiles, and on that page I have an asp.net image control that I dynamically populate at runtime based on the users profile image.
I have created several themes, just modifying css to display the profiles with different background and different layouts.
For fun I have created one theme that is kind of like the matrix, and I would like to be able to take the users profile image and change it to a 'green scale' so to speak, or even just a straight up green color, more so this one #20f380. The profile images are just jpg, and are already cartoonish so they should change to green without the image looking to bad.
Is there a way to use code behind to change an image's colors?
C# or VB is fine, currently I've not been able to find any tutorials that work for me, or are close to what I am trying to do.
