<asp:TextBox ID="TextBox2" text="From:" style=" visibility: hidden" runat="server" BackColor="#999999" BorderColor="Black" BorderStyle="Double"></asp:TextBox>
<asp:ImageButton ID="ImageButton2" runat="server" BackColor="#99CCFF"
BorderColor="#84C1FF" BorderStyle="Outset" OnClientClick="MJavascriptFunction();return false;" Height="35px"
ImageUrl="search11.png" Width="56px" />
<script type="text/javascript">
function MJavascriptFunction(obj) {
var theControl = document.getElementById("<%=Textbox2.ClientID %>");
theControl.style.display = "block";

Change
改变
theControl.style.display = "block";
To
到
theControl.style.visibility="visible";
In your Code you set the visiblity option to "hidden", So you need to use the same property in javscript
在您的代码中，您将可见性选项设置为“隐藏”，因此您需要在 javscript 中使用相同的属性
Alternatively you can change the HTML inline CSS to style="display:none".
或者，您可以将 HTML 内联 CSS 更改为 style="display:none"。
