Question

I have a method that loops through a list and creates Links using the LinkButton control. For the purpose of this question, assume that it is a list of colors and that I have 5 colors: red, green, blue, red, and yellow. Here is a code snippet of how I am creating the links and adding the event handler.

foreach(color in colors) {     LinkButton lb = new LinkButton();     lb.Text = color.name;     lb.Click += new System.EventHandler(this.colorClick);      lb.CommandName = 'CommandName';     lb.CommandArgument = 'CommandArgument';     lb.ID = color.Id; } 

In the even handler, colorClick, I am bolding the clicked link by doing the following:

protected void colorClick(object o, EventArgs e) {     LinkButton lnk = (LinkButton)o;     lnk.Style['font-weight'] = 'bold';      //Process clicked link. } 

The above code works fine as far as bolding the currently clicked link, the problem I run into is that assume that the link clicked was Red, so Red would be bold, if I click Blue, I want to bold the link Blue, but unbold Red. I have tried:

lnk.Style['font-weight'] = 'normal'; lnk.Font.Bold = 'false'; 

but, it occured to me that while the above maybe correct, I am doing it in the wrong spot (colorClick). What I was thinking is that I probably have to remember the previously clicked link and unbold that one, but I am unsure of how to do that.

You’ve got three options:

1. Store the link that was previously bold and un-bold it.
2. Iterate the links and look for the one link that’s bold and un-bold it.
3. Or just un-bold everything before setting the link to bold.

The code to remove font-weight is:

lnk.Style.Remove('font-weight')
