Hi ,

Basically I want to display a popup box only at a specific time in asp.net application. so i'm using the following code..

aspx page :
Collapse
<head runat="server">
<title>Untitled Page</title>
<script type="text/javascript">
function timedMsg()
{
var t=setTimeout("alert('good morning!')",6000);
}
script>
</head>

C# code :
Collapse
protected void Button1_Click(object sender, EventArgs e)
{
StringBuilder script = new StringBuilder();
script.Append("<script type=\"text/javascript\">");
script.Append("timedMsg();");
script.Append("script>");
Page.ClientScript.RegisterClientScriptBlock(typeof(object), "JavaScriptBlock", script.ToString());
}

this works fine but i dont want to set settimeout as fixed as 6000. i need to retrieve value from database and assign it to settimeout. so i modified the coding as below..

aspx page :
Collapse
<head runat="server">
<title>Untitled Page</title>
<script type="text/javascript">
function timedMsg(var x)
{
var t=setTimeout("alert('I am displayed after 3 seconds!')",x);
}
script>
</head>

C# code :

Collapse
protected void Button1_Click(object sender, EventArgs e)
{
int x = 6000;
StringBuilder script = new StringBuilder();
script.Append("<script type=\"text/javascript\">");
script.Append("timedMsg(x);");
script.Append("script>");
Page.ClientScript.RegisterClientScriptBlock(typeof(object), "JavaScriptBlock", script.ToString());
}

but this code is not working. the alert box is not popping up. is this a correct method to pass values to the script?. or what else to be done to meet the requirement?.. pls help me..

thanks..

function timedMsg(x) {
    var t=setTimeout("alert('I am displayed after 3 seconds!')", x);
}

protected void btn1_Click(object sender, EventArgs e)
{
   String script = String.Format("javascript:timedMsg('{0}');", txt1.Text);
   Page.ClientScript.RegisterClientScriptBlock(typeof(object), "JavaScriptBlock", script, true);
}

script.Append("timedMsg(x);"); i think this is the problem the entire parameter is treated as

one variable x is also a constant string try this following code

script.Append("timeMsg("+x+");");//in this x is filled with that value previous one x is treated
like string .
