Hi Yudi,

I have attached the snapshot again. Please help.

I modified the FirstExperience.aspx sample file of WebScheduler by adding OnCallOutInitialize client-side event; OnCallOutShow client-side event; and a JS function named Redirect().

The JS function is as follow:

<script>
    function WebScheduler1_OnCallOutInitialize(controlId)
    {
        var WebScheduler1 = ISGetObject(controlId);
        var b1 = document.createElement("Button");
        var tr1 = document.createElement("tr");
        var td1 = document.createElement("td");

        b1.id = "Button1";
        b1.innerText = "Test";
        b1.attachEvent("onclick", Redirect);
        WebScheduler1.GetCallOutContainerElement().childNodes[0].appendChild(tr1).appendChild(td1).appendChild(b1);;
        WebScheduler1.CallOutSetHeight("135");

        return true;
    }

    function WebScheduler1_OnCallOutShow(controlId, action)
    {
        var WebScheduler1 = ISGetObject(controlId);

        return false;
    }

    function Redirect()
    {
        alert("test");

        return false;
    }
</script>

Save all the changes and view the page in Google Chrome version 36.0.1985.125 m (most recent version of Chrome as of now). However, I was unable to reproduce the reported problem in my local end. The alert (as user click the button) shown without problem.

I enclosed the modified version of FirstExperience.aspx sample as attachment. You need to copy and replace the existing file in the local WebScheduler sample project in order to view it in browser.
Should you find anything that I might miss during my attempt in order to reproduce the reported problem, please feel free to let me know.

For your information, I'm using WebScheduler 4 build 4 and WebUI.NET Framework 3 build 912 assembly.

Thanks for the Response.

I have used the Redirect method with alert as you shown. The alert functions gets triggered. But i am actually    using redirecting to a page instead of alert. I have problem in redirecting to another page. 

  function Redirect() {

        var temp = window.location.pathname;

        window.location = "/Patient/Patient_Search.aspx?tempPatientName=" + text;

        return false;

    }

This rediricting thing works perfect in IE browser but this redirect function wont even triggers in Chrome if i use the above code. So, alert works but problem is only with Redirecting to another page.

I managed to get the redirecting problem resolved by replacing/modifying b1 element from button element into input element. Please apply the changes below in OnCallOutInitialize function.

function WebScheduler1_OnCallOutInitialize(controlId)
{
    var WebScheduler1 = ISGetObject(controlId);
    var b1 = document.createElement("input");
    var tr1 = document.createElement("tr");
    var td1 = document.createElement("td");

    b1.id = "Button1";
    b1.type = "button";
    b1.value = "Test";
    b1.attachEvent("onclick", Redirect);
    WebScheduler1.GetCallOutContainerElement().childNodes[0].appendChild(tr1).appendChild(td1).appendChild(b1);;
    WebScheduler1.CallOutSetHeight("135");

    return true;
}

Glad to hear that replacing button element into input element helps.
