Data Controls :: Conditionally Change Font Color Of GridView Cell Text

May 7, 2015

I have a gridview that contains columns of electrical specification (value, resistance, etc.).  The rows are populated with archival data from previous versions of th same part (rev A, rev B, etc.).

The question is: is there any way for me to review each row and set the font color to red if the value is different from the cell below, or above?  This would highlight where changes were made to each individual revision of a part from the previous version.

Forms Data Controls :: Lighten Too Many GridViews In One Aspx Page

Oct 30, 2010

the project I'm working on has become quite bigger then expected. And now I have pages containing about ten different GridViews (and it is likely to increase!!), each one with its own EditItemTemplate, ItemTemplate, FooterTemplate, style, properties, etc. And, of course, in the code-behind (C#) each Grid has its events handled. You can imagine: it is a mess, playing with visibility of each one, ImageButtons to hide them, further buttons for other actions. I decided to handle only events in the code behind, while using partial classes and additional classes for the rest of the code (SQL queries and everything else), but still, it's gettin a mess.

Well, my question is: is there a way to, how can I say, have a kind of separate files, where these objects are deployed, and from where I can reference them when running the application. Or, if it exists, a way to lighten aspx page and asp.cs pages. I know it's part of the job, so here the question is just intended to investigate whether a possibility to "distribute" the objects used in a web page exists.

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();
}
}
}
