How to get value of style attribute from a code behind property?
Question
In my .aspx I have this :
<style type="text/css">
.item .item_background .item_general_info .button_wrapper .add_button {
background-color: /* MyProp from code behind */
}
</style>
On the code behind :
public String MyProp
{
get {return DB.GetColor();}
}
How can I set the value of the background-color dynamically from the code behind ?
Thanks

If this is a aspx, you can try to define that member on the class as a protected member:
protected string _myServerColor;
Then assign that prop when the page loads:
protected void Page_Load(object sender, EventArgs e) { _myServerColor = "#FFF"; // assign this to your db color }
And then, as long as your style tag is within the same page, you could do:
<style type="text/css">
.item .item_background .item_general_info .button_wrapper .add_button {
background-color: "<%= _myServerColor %>";
}
</style>
Cleanest way would be to make this controls runat="server" so you could assign properties from the backend directly.

You can add a style attribute to your CSS style class from code-behind this way:
Style style1 = new Style();
style1.BackColor = Color.Orange; // Insert the desired color here
Header.StyleSheet.CreateStyleRule(style1, null, ".item .item_background .item_general_info .button_wrapper .add_button");
In order for that to work, the head section of the page must have the runat="server" attribute:
<head runat="server">
<style type="text/css">
.item .item_background .item_general_info .button_wrapper .add_button
{
...
}
</style>
...
</head>
