Currently, my UserControl Page utilizes ASP.Net Controls such as TextBox and Drop down List which are all set to be invisible using the Edit function. On the same page, there is a Link Button for editing that I would like to make visible at the client side. Can anyone provide suggestions on how to achieve this or propose an alternative method?
If you want to achieve this functionality using JavaScript, the recommended approach is to remove the OnClick attribute from the LinkButton and utilize the OnClientClick attribute to invoke a JavaScript function instead:
<asp:LinkButton ID="lb_link_button" runat="server" Text="Click Me" OnClientClick="return ToggleShowHide()"/>
Below is an example of a JavaScript function that can show/hide a control named my_control by manipulating its style.display property:
<script type="text/javascript">
function ToggleShowHide() {
var control = document.getElementById("<%= my_control.ClientID %>");
if (control.style.display == "none") { control.style.display = "block"; }
else { control.style.display = "none"; }
return false;
}
</script>
There are various ways to reference the controls for showing/hiding, and this is just a simple illustration.
It's important to note that the controls intended to be set as visible/invisible should not have their Visible property explicitly set to false. Instead, they should be initially declared with a style of display:none; like so:
<asp:Control runat="server" ID="my_control" Visible="true" style="display:none;"/>
