Deactivate LinkButton

In a div element, I have a ContentPlaceHolder, and inside that is a Linkbutton.

I am attempting to dynamically remove the link button but encountering the following error:

Error: DOM Exception: NOT_FOUND_ERR (8).

Below is my code snippet:

<div id="leftcol" style="z-index: 0">
    <asp:ContentPlaceHolder ID="ContentPlaceHolder2" runat="server">
    <asp:LinkButton  CssClass="childLI" ID="tblRSManswers" runat="server" Text="RS Manswers" OnClick="ChildLink_Click" >

Javascript code:

var child = document.getElementById("tblRSManswers"));
alert(child);
var parent = document.getElementById("ContentPlaceHolder2"));
alert(parent);
parent.removeChild(child);

P.S: The alerts are not NULL.

Answer №1

removeElement requires a direct parent element. The HTML you provided appears to be incomplete, so it may not accurately reflect your actual implementation in the application.

Consider using:

element.parentNode.removeChild(element);

Answer №2

Give this code a try:

var element = document.getElementById("<%= tblRSManswers.ClientID %>");
if (element) {
  element.parentNode.removeChild(element);
}

Note on the Update:

Remember that in ASP.Net, ContentPlaceHolders act as mere placeholders for rendering HTML elements and are not actual DOM elements. Therefore, attempting to find a content place holder with JavaScript will always result in a null value since it is not rendered in the DOM.
