Question

I know there are a few hundred answers to questions like this on StackOverflow but I just am not ‘getting it’.

I have a shopping cart in C# / asp.net. On a product page is a “Reserve” button. When the button is clicked the first time I want it to hide the product details panel (named ProdDet) and show the calendar panel. My challenges are:

1. I can not do it as an OnClientClick because I’m using an OnClick to do other processing and can’t get them both to behave together.

2. I don’t understand a lot of what I’ve read. I am fairly new to ASP.NET and C# and could use a little handholding.

3. There are several places in my code I’d like to use HidePanel and ShowPanel

My relevant pseudo-code (working and not):

Server-side:

public void CalendarButton_Click(object sender, EventArgs e)
{
    some processing 
    if (everything ok) {
       CalendarLiteral.Text += "<iframe...";
       Hide_Panel(); // not working.
    }
}

public void HidePanel()
{
       Page.ClientScript.RegisterStartupScript(
         ...just not getting it or even sure this is the right thing to do.
       );
}

Client-side in head section:

<script type="text/javascript">
      function HideContent(d) {
      document.getElementById(d).style.display = "none";
      Alert("Hiding " + d);
      }
</script>

It’s not terribly bad but some of this server/client/.NET stuff is not easy to self-teach when coming from a straight C background. Any help is appreciated!

Answer 1

You need to call the function HideContent with the right arrgument. Register a script that would do exactly that.

Page.ClientScript.RegisterStartupScript(this.GetType(),"Script name",
"<script type=text/javascript> 
HideContent('foo') 
</script>");
