Question

我在一个页面上有几个文本框和一个用户控件。我想要的是当用户特别点击或文本框获得焦点时，它应该打开弹出窗口。用户控件包含填充加载事件的网格。现在，当用户点击按钮时，弹出窗口应该关闭，专利页面的文本框应该填充所选行的值。这该怎么做？这是我的.aspx页面的代码并使用控制页面。父页面代码

<form id="form1" runat="server">
 <asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<div>

    <table class="style1" width="100%">

将此onfocus属性添加到文本框中。

onfocus="$find("<%= YourModalPopupExtenderID.ClientID %>").show();"

单击文本框时，在ModalPopUpExtender中打开用户控件
