Help needed to remove <br> tags in between the <input> tags.
For a particular requirement of mine, I had to create checkboxes "by hand" and add them to a panel. I could not make use of the CheckboxList control.
To ensure that each chkbox goes to a new line, I had to add a literalcontrol(<br>) after each chckbox that I added.On rendering the chkbox section of the page has this source -
<input id="id0" type="checkbox" name="id0" /><label for="id0">ABC1</label><br>
<input id="id1" type="checkbox" name="id1" /><label for="id1">ABC2</label><br>
<input id="id2" type="checkbox" name="id2" /><label for="id2">ABC3</label><br>
<input id="id3" type="checkbox" name="id3" /><label for="id3">ABC4</label><br>
<input id="id4" type="checkbox" name="id4" /><label for="id4">ABC5</label><br>
Now on click of a client side button I delete the chkboxes that are checked, for this I loop thru the tags of type input determine the boxes tht r cheked and then delete them, this part is fine, the problem comes when I try to get rid of the <br> tags, once I determine that a chkbox needs to b deleted, how do I delete the <br> too that follows it?Can I get the "next element" of a given element, given that I can uniquely identify the input and for tags that I need to delete. How do I uniquely identify the <br> tag that needs to go once a chkbox is removed?
In case ur wondering why I need to remove the <br>, its coz the chkboxes do not move up as the ones above r removed coz the <br>s force them to b rendered on successive lines, so there is a "void" of sorts left behind at all places where I remove the chkboxes.
Pls help me fix this, and again using a Chkboxlist is not an option.

What an interesting problem.
The <br /> tag can have an ID: <br id="br1" />
Does that help?

SGWellens Hi Demon try like this
function removeSelected()
{
var tg1 = document.getElementById("cbDiv").getElementsByTagName('input'); var tg2 = document.getElementById("cbDiv").getElementsByTagName('br');for(i=0;i<tg1.length;i++)
{
if(tg1[i].checked){
document.getElementById(
"cbDiv").removeChild(tg1[i]);document.getElementById("cbDiv").removeChild(tg2[i]);}
}
}
<

input id="id3" type="checkbox" name="id3" /><label for="id3">ABC4</label><br><input id="id4" type="checkbox" name="id4" /><label for="id4">ABC5</label><br> </div><
input id="Button2" type="button" value="button" language="javascript" onclick="removeSelected()" /></form> </body>
</

sivakl_2001 Without using <br> tag, it could be a solution for you
Create <span> tag around your <input>and <label> tags
<div> <span><input id="id0" type="checkbox" name="id0" /><label for="id0">ABC1</label></span> <span><input id="id1" type="checkbox" name="id1" /><label for="id1">ABC2</label></span> <span><input id="id3" type="checkbox" name="id3" /><label for="id3">ABC4</label></span> <span></span> <span><input id="id4" type="checkbox" name="id4" /><label for="id4">ABC5</label></span> </div>Use Stylesheet for <span> tagThanks.<style type="text/css"> span{ display:block; }

Thanks for replying.
Mayb Im asking u a very stupid question, but well I dont know abt it. I had tried in my naivety to assign an id to a Literal control but when it renders, its just a plain <br>.
Here is wat I tried doing -
for( int i = 0;i<5;i++){
CheckBox ckbox = new CheckBox();ckbox.ID =
"id" + i.ToString();ckbox.Text = "ABC";ckbox.EnableViewState = true;newPanel.Controls.Add(ckbox);
LiteralControl litctl = new LiteralControl("<br>");litctl.ID = ckbox.ID + "lit";newPanel.Controls.Add(litctl);
}
Is there a differnt method to assign an id to the br tag, To give u a background, I need the brs to ensure that my chkbxes render on a new line.
Thanks again.

input id="Button2" type="button" value="button" language="javascript" onclick="removeSelected()" /></form> </body> </html>
An interesting sltn - Ur banking on the fact tht the first <input> wld b tied with the first <br>, innovative indeed, let me try it, I guess it wld work by the looks of it. Thanks again!!

Hi NHQUE,
Thnks for helping me out, well this page is in 1.1, so when it renders with the brs that I have added, it goes like this -
<span><input id="id0" type="checkbox" name="id0" /><label for="id0">ABC1</label></span><br>
<span><input id="id1" type="checkbox" name="id1" /><label for="id1">ABC2</label></span><br>
<span><input id="id2" type="checkbox" name="id2" /><label for="id2">ABC3</label></span><br>
<span><input id="id3" type="checkbox" name="id3" /><label for="id3">ABC4</label></span><br>
<span><input id="id4" type="checkbox" name="id4" /><label for="id4">ABC5</label></span><br>Are u telling me to link this with a css tht has the property for display:block set for the span, and then it wld render on a new line w/o the brs. I did not get a chnce to test this and Im afraid I cant until tomorrow, but then if this works with the css, I will defenitely sleep better tonight :)

QDemon19 Yes, if you see my post, I have used CSS for <span> tag.
Remove <br>, it is not required . As <span> tag will be handled by CSS, it is not required to <br> tag at all. Since the CSS used in the <span> tag makes its style as BLOCK.
Well, I tested it in IE as well as FF. There is no problem. Have a nice sleep tonight!
Thanks.
