As I was a Windows programmer it was so easy to show a message box on a form.
But on an ASP.NET page I don’t know how can I show it?
Actually I have some condition and based on that I want to show a message box to the user to get his/her response and based on that response I want to continue.
For example I want to ask the user “Do you want to continue?” with two buttons “Yes” & “No”.

Method 1
You can do this using JavaScript. Include this snippet in your code –
<script type='text/javascript'>
document.getElementById("someButtonId").onclick = function() {
var confirmation = window.confirm("Are you sure?"); //confirmation variable will contain true/false.
if(confirmation) { /* Write code for Yes */ }
else { /* Write code for No */ }
}
</script>
Method 2
The only way to show a Yes No dialog, is to design a custom one (Javascript confirm can only produce OK and Cancel).
Luckily, ASP.NET Ajax controls (Ajaxcontroltoolkit) makes this job easy, as you can have a panel as your messagebox with the buttons you want, and have a ModalPopupExtender to imitate a dialog.
EDIT:
For what you ask with javascript, you can do it (and it is a much simpler solution than any seen so far), but prepared to only have OK and Cancel as the two possible answers. UI Designer Nightmare ! 🙁
Basically, have the following two properties in your aspx page for that button or whatever:
onClientClick = "javascript:confirm('you sure you wanna do this?');" onClick="myButton_Click"
onClick will only run if OK is pressed on the msg dialog.
Method 3
window.alert(); window.confirm(); and window.prompt();
This is I guess what you are looking for.
Method 4
You can use
window.confirm
for this.
It displays a modal dialog with a message and two buttons, OK and Cancel.
Eg:
if (window.confirm("Want to see my mood ring?"))
{
// wants to continue
}
else
{
// cancel the action
}
Edit:
You can also develop custom message boxes using jQuery. Here is a nice one
Method 5
.aspx markup
<head runat="server">
<title>Sample Page</title>
<script type="text/javascript">
function doSubmit(){
var confirmation = window.confirm("Are you sure?");
document.getElementById("HiddenField1")["value"]=confirmation;
return true;
}
</script>
</head>
<body>
<form id="form1" runat="server" onsubmit="return doSubmit()" >
<div>
<asp:HiddenField ID="HiddenField1" runat="server" />
<asp:Button ID="Button1" runat="server" Text="Button" />
</div>
</form>
</body>
Code-behind
protected void Page_Load(object sender, EventArgs e)
{
if (HiddenField1.Value == "true")
{
}
else
{
}
}
Method 6
If you REALLY want to have “yes”/”no” buttons (or any buttons that are not your standard OK/Cancel for that matter) you can do the following:
Main page:
<html>
<body>
<script>
function ShowYesNo() {
var answer = window.showModalDialog("myModalDialog.htm", '', "dialogWidth:300px; dialogHeight:200px; center:yes");
document.write('Clicked yes');
} else {
document.write('Clicked no');
}
}
ShowYesNo();
</script>
</body>
</html>
MyModalDialog.htm
<html>
<body>
<p> Do you want to proceed?" </p>
<input type = "button" id = "buttonYes" value = "Yes" onclick = "buttonOnClick('yes')">
<input type = "button" id = "buttonNo" value = "No" onclick = "buttonOnClick('no')">
<script type = "text/javascript">
function buttonOnClick(message) {
window.returnValue = message;
window.close();
}
</script>
</body>
</html>
Method 7
You can use the confirm JavaScript function, but that will be limited to OK/Cancel as options. If this is not what you want, you can lean on the VBScript MsgBox client-side function. Bear in mind that doing so will only work with Internet Explorer.
function PerformDelete(id)
{
if(confirm("I am about to delete this record. Is this ok?"))
{
//your code here
}
}
Method 8
i have a solution for you, may be it help you, for using that same message box or conformation dialog of c# in Asp.Net, first you should add namespace,
Using System.Windows.Forms;
then, where you want to call a message box or conformation dialog, you can just call it as simple as in c#, like:
DialogResult dialogResult = MessageBox.Show(“Are you shure?”, “Some Title”,
MessageBoxButtons.YesNo);if (dialogResult == DialogResult.Yes) { Response.Redirect("Page.aspx"); } else if (dialogResult == DialogResult.No) { MessageBox.Show("You Select Nothing to do... :("); }
I think, I explained properly, sorry for any mistake….
