<script type="text/javascript">

    // Using the DialogOptions class
    function OpenDialog(strPageURL) {
        var dialogOptions = SP.UI.$create_DialogOptions();
        dialogOptions.url = strPageURL; // URL of the Page
        // Width of the Dialog
        dialogOptions.width = 800;
        // Height of the Dialog
        dialogOptions.height = 630;
        // Function to capture dialog closed event
        //dialogReturnValueCallback - A function pointer that specifies the return callback function. The function takes two parameters, a dialogResult of type SP.UI.DialogResult Enumeration and a returnValue of type object that contains any data returned by the dialog.
        dialogOptions.dialogReturnValueCallback = Function.createDelegate(null, CloseCallback);
        // Open the Dialog
        SP.UI.ModalDialog.showModalDialog(dialogOptions);
        return false;
    }

    // Dialog close event capture function
    function CloseCallback(strReturnValue, target) {
        location.reload(true);
    }</script>
