C# - Programmatically Change Background Colour Of Some Text?

Mar 7, 2011

I have implemented master pages using this example How to implement a status bar in an ASP.NET application?. I have a property on my SiteMaster.cs inherited MasterPage called Environment. On my MasterPage.master I have this code:

<body>
<form id="frmMaster" runat="server">
<.. some content removed for brevity ...>
Environment: <%= this.Environment %>
</form>
</body>

What I would like to do is evaluate this.Environment and if it is "LIVE" then colour the background of this.Environment text red, and if it's "TEST" colour it yellow. How would I do this?

UPDATE I've just added this code to MasterPage.master

protected void Page_Load(object sender, EventArgs e)
{
lblEnvironment.Text = this.Environment;
if (this.Environment == "LIVE")
{
lblEnvironment.BackColor = System.Drawing.Color.Red;
}
}

The page loads, but the text does not get set, it's blank! Also the old text, that was populated is now blank too (I left the old code there for now). I also get a warning in Visual Studio:

'ASP.masterpage_master.Page_Load(object, System.EventArgs)' hides inherited member SiteMaster.Page_Load(object, System.EventArgs)'. Use the new keyword if hiding was intended.

UPDATE2: This is what I have in SiteMaster.cs

using System;
using System.Web.UI;
public class SiteMaster : MasterPage
{
public string StatusText { get; set; }
public string StatusTime { get; set; }
public string Environment { get; set; }
protected virtual void Page_Load(object sender, EventArgs e)
{
if (!this.IsPostBack)
{
if (Session["status"] != null)
{
this.StatusText = Session["status"].ToString();
this.StatusTime = Session["statusTime"].ToString();
}
this.Environment = Session["environment"].ToString();
}
}
}

Forms Data Controls :: How To Change The Colour Of Text

Jun 21, 2010

I have a gridview and I use a sort function there, which means that if I click on the header of some column the table is sorted by this column. What I need is to change the colour of header of column which I sorted the table by. E.g. if I sort the table by first name, I click on the header of column called "first name", then the table will be sorted by first name and the colour of the text "first name" will change. The sorting is not a problem but I don't know how to change the colour of text.

Web Forms :: Skins Not Working - Change Colour Of Submit Button

Jan 25, 2011

I have never used skins before, so I went online and found some samples. I am trying to get ANY skin to work, so I have an incredibly simple site, a master page, the default.aspx, the skin file. I am missing something because as near as I can tell my skin file is set up correctly and I THINK I am doing it all correctly, but the skin file / contents seems to be ignored. Here is the master page, all I am trying to do is change the colour of the submit button. I figure once I get the skin recognized the rest should be easy...

[Code]....

My default.aspx has NO changes to it. I created a new one added nothing so I am not displaying it here. In my App_Themes directory a new folder called 'First' was created. In that folder is a file called 'First.skin'. The contents of First.skin is: [Code]....

Maybe there is something in the web.config that the people who made the samples assumed I would know about... not sure.

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.
