Web Forms :: Programmatically Access A Themed Page's Background Color Or Other CSS Property?
Jun 18, 2010
This was originally posted, in error, to another forum. Not sure how that happened. Anyways, here goes... I have a web app that uses javascript functions to make rounded corners. One of the functions requires two colors as parameters. I cannot change this function definition. My web app is in asp.net 4.0 and uses master pages and themes. To facilitate programmatic access, I moved all javascript declaration into the code behind file of the master page. It gets generated in the load event: I declare it there as a big
string (using StringBuilder) and then put it into the page with Page.
ClientScript.RegisterClientScriptBlock(... Now that I have introduced themes into my application, I have discovered a serious problem. These themes each utilize their own CSS and skin files to paint the various elements of the app's web pages in different colors (of course). But remember, as parameters, one of my javascript functions requires two colors. And now that I have themes I can no longer manually code these colors into the javascript declaration... Now I have to discover a way to extract the background color and one other color from the current theme's CSS file. Then I can feed that into the javascript declarations in the master page's PageLoad event in the master page's code behind file. This would allow the javascript function to be called on the page load and to use the current theme's colors as parameters.

What do I have wrong here? This page is essentially broken into 5 divs, the middle 3 divs that represent the left, middle and right page columns are wrapped in a div with the id content. I linked to the page if you want to view the source. It wouldn't go in this message as a snippet very well when I tried.
Here is the style for #content
#content
{
background-color:White;
}
How do I get the whole background of #content to show as white? link to a live version of[URL]

I tried to start my first ASP.NET MVC program and wanted to modify some parts of the project.
When i tried to change the background color of the page body, i went to the Site.css file and changed the color to #ffffff. When I rebuilt the program the color remained the same, and I found out the only way to change it is to delete it and load it back to the project.

I have a class (let's call it Car) that has a property of type System.Drawing.Color (Call it CarColor). I have a script service function that uses this Car class as a return value, which works just fine. I then have another script service function that takes a Car object as a parameter. I would like to change the color of the car in Javascript, but I am finding it difficult to do so without adding another parameter that takes in the color as a string and is then translated at the server. Are there any ideas on how to set the Color property of the Car object in Javascript and maintain it through to the server?

I'm trying to make a page, with a textbox, and a linkbutton. In the textbox you can enter any hex colour code you want, then you can click the linkbutton and the pages background will change to that colour. But I don't want the page to postback. I was trying this with themes, and then dynamically editing the CSS file. But neither has worked.

I would like to programmatically access a div in a style sheet for my master page and change its height value depending on the content page loaded.
Can this be done using Javascript in the Master page or in the code behind for the respective page? What I would like is something such as this if possible
When this content page loads, change the height value of this div in the css file
I don't want to use separate Master pages as this seems to defeat the whole purpose of the Master page

I have an asp.net app that allows users to create personal pages which can be publicly accessed thru a "directory" page. The content of the pages is stored in sql server, so a given user's page is dynamically created thru the code that executes when the relevant link on the directory page is clicked.
I would like to take this a step further by allowing access to a given user's page directly thru the browser's address bar, something like www.thegreatestsite.com/jim (pretty much like You Tube, Facebook, etc.).
I could achieve this by manually creating a folder under the root, called "jim" and putting a default.aspx page in it which would have code in it's load event that would dynamically create jim's page.
However, I would like this "additional feature" to be created automatically, as part of the sign up process of the user.

I'm using panel controls because of the grouping text. I like the clean look this provides for this portion of my form. I don't like the way the panel control works though. I have both the height and the width set in the css file. I also set the background color. The grouping text is set in the mark up of the panel. The problem is that the background color is not contained with in the outline or the grouping text that the control creates. It goes beyond it. To test this I set a border to the panel in the css file. I then set the height and the width for this in the css. When this is viewed in the browser the outline created with the grouping text is no where near the size of the border I created. The border reflects the dimensions of the div. But, the outline of the grouping text and the grouping text itself is more the size of the contents. I assume this is normal for this control. Has anyone had this issue or know how to get around this? How do I get the background color to be with in the panels grouping text and it's outline? How do I get the panel to be the same as the size I set in the CSS?
