弹出窗口，其中textbox_onchange不起作用?

问题描述

您好，程序员在这里遇到了一些我无法解决的错误.
香港专业教育学院设法在我的母版页上添加一个弹出窗口，以便我每次都可以调用它

hello programmers, got a few errors here that I cannot solve myself.
Ive manage to add a pop up window on my master page so that I could call it everytime

<script type="text/javascript">


        function OpenPopup() {
if (window.showModalDialog) {
    window.showModalDialog("PopUp.aspx", "PopUp",
"dialogWidth:550px;dialogHeight:300px");
} else {
window.open('PopUp.aspx', 'name', 'height=300,width=550,toolbar=no,directories=no,status=no,menubar=no,scrollbars=no,resizable=no ,modal=yes');
}
}
    </script>

看到我正在打电话给PopUp，aspx
现在在我的popup.aspx上，这是最棘手的部分
我将其与带有源txtSearchBox的自动完成扩展器绑定在一起

See that I am calling PopUp,aspx
Now on my popup.aspx here is the trickest part
I am binding it with autocomplete extender with the source txtSearchBox

    </form>

看到我的txtSearchbox具有ontextchange和自动回发.现在我可以获取想要的值，但是它不会保留在窗口弹出窗口中，因此它将值转移到新窗口中.

See that my txtSearchbox has ontextchange and auto postback. Now i can get the value i want but then it doesnt remain in the window popup thus it transfer the value to a new window.

Protected Sub txtSearchBox_TextChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles txtSearchBox.TextChanged
        txtCourseName.text = txtSearchBox.text    End Sub
