Loop through <li> with ASP.NET

Question

I want to change the visibility of the <li> server side of the collections.

My HTML code looks like this:

 <ul> <li runat=server id="l1"></li> <li runat=server id="l2"></li> <li runat=server id="l3"></li> <li runat=server id="l4"></li> ... </ul> 

Now that I said, I want to iterate over the collection and change the visibility of some li using my id

sort of

 for (i=0;...) { l+I.visible=false } 

Any help would be appreciated.

Answer 1

Unused , but this may work:

First change, your ul will be running on the server.

 <ul runat="server" id="myList"> 

Then iterate through it

 foreach (Control li in myList.Controls) { if(li is HtmlGenericControl) li.Visible = false; } 

Code example:

Html:

  <ul runat="server" id="myList"> <li runat=server id="l1">1</li> <li runat=server id="l2">2</li> <li runat=server id="l3">3</li> <li runat=server id="l4">4</li> </ul> <asp:Button ID="Button1" runat="server" Text="Button" onclick="Button1_Click" /> 

Click Handler Button:

 protected void Button1_Click(object sender, EventArgs e) { foreach (Control li in myList.Controls) { if (li is HtmlGenericControl) li.Visible = false; } } 

EDIT 2 - Code in VB.NET

 For Each li As Control In myList.Controls If TypeOf li Is HtmlGenericControl Then li.Visible = False End If Next

Try the following:

  <ul> <% for (int i = 0; i <= 10; i++){%> <li runat=server id="l<%Response.Write(i); %>"><%=i%></li> <% } %> </ul> 

only inside the html page!
