Open/Close or Show/Hide Ajax Modalpopupextender using JavaScript in asp.net

Dec 24, 2011
Introduction: 

Here I will explain how to show/hide Ajax modalpopupextender using JavaScript in asp.net.

Description: 

In previous posts I explained some of the samples relating to Ajax modalpopupextender. During the time whenever I worked on to prepare samples for Ajax modalpopupextender I got requirement like close the modalpopupextender whenever I click on close icon for that more check this example Ajax Confirmation box. Generally in Ajax modalpopupextender we will set two properties TargetControlID and CancelControlID like

Ex: TargetControlID="btnShowPopup" CancelControlID="btnNo"

Here whenever we click on btnShowPopup button control modalpopupextender will show popup and when we click on btnNo button it will close the popup. Now I want to open popup and close popup whenever click on other button controls also in that case what we can do? By using JavaScript $find() function we can show or hide modalpopupextender easily. 

JavaScript Functions will be like this

<script language="javascript" type="text/javascript">
//Function to Hide ModalPopUp
function Hidepopup() {
$find('ModalPopupExtender1').hide();
}
//Function to Show ModalPopUp
function Showpopup() {
$find('ModalPopupExtender1').show();
}
</script>

Here 'ModalPopupExtender1' is our modalpopupextender id.

Our Sample Page will be like this


<html xmlns="http://www.w3.org/1999/xhtml">
<head id="Head1" runat="server">
<title>Untitled Page</title>
<script language="javascript" type="text/javascript">
//Function to Hide ModalPopUp
function Hidepopup() {
$find('ModalPopupExtender1').hide();
}
//Function to Show ModalPopUp
function Showpopup() {
$find('ModalPopupExtender1').show();
}
</script>
</head>
<body>
<form id="form1" runat="server">
<ajax:ToolkitScriptManager ID="ScriptManager1" runat="server">
</ajax:ToolkitScriptManager>
<asp:Button ID="btnShowPopup" runat="server" style="display:none" />
<ajax:ModalPopupExtender ID="ModalPopupExtender1" runat="server" TargetControlID="btnShowPopup" PopupControlID="pnlpopup"
CancelControlID="btnNo" BackgroundCssClass="modalBackground">
</ajax:ModalPopupExtender>
<asp:Panel ID="pnlpopup" runat="server" BackColor="White" Height="100px" Width="400px" style="display:none">
<div>
Confirm Box
<a href = "javascript:void(0)" onclick = "closepopup()">Hide PopUp</a>
<a href = "javascript:void(0)" onclick = "Showpopup()">Show PopUp</a>
<asp:ImageButton ID="btnYes" OnClick="btnYes_Click" runat="server" ImageUrl="~/Images/btnyes.jpg"/>
<asp:ImageButton ID="btnNo" runat="server" ImageUrl="~/Images/btnNo.jpg" />
</div>
</asp:Panel>
</form>
</body>
</html>
