I have put following code on html page.
<td bgcolor="<%=TableHeaderColor%>"> </td>
However it seems html understand above code and it renders colors. when I change letters in between
<%= %> , I get different colors.
Can someone help me to understand this?
Html doesn't understand a thing, webserver does. Before the page is sent to the client, it's being translated every time and the client (web browser) sees only the generated html result.
In page load : (Server side)
page-load ()
{
if(any condition )
{
TableHeaderColor="Red";
}
else if(any condition )
{
TableHeaderColor="Yellow";
}
else if(any condition )
{
TableHeaderColor="Green";
}
}
Now if you call this TableHeaderColor in your client side as your way , it's changing on your condition ,
It's just a key only
Try this :
<td style="background:<%=TableHeaderColor%>"> </td>
All the asp.net tags you write will be translated once they pass the server.
For example: when you use the tag <asp:hyperlink> it will be translated to <a href="">
try opening the source of a website written in asp, you won't see the asp tags but just html
Is not intepreted by HTML, but by server side page processing.
Ref:
With ASP, code was enclosed within <%... %> tags and page processing began with the first statement following the first <%> tag. With ASP.NET, any code that is to be processed as soon as the page is loaded must be included within the Page_Load intrinsic event. You can still write code in <%... %> blocks, but it will be executed at render time (in top-down fashion, as in ASP) after the page is loaded. If you need to execute initialization code, it should appear in the Page_Load event, which is raised immediately after the page is loaded by the ASP.NET engine
