AjaxToolkit ModalPopupExtender：如何将焦点设置到弹出面板中的控件？
当用户按下按钮时，我想显示一个模式对话框以从文本框中捕获几个值并将这些值提交到服务器。
当显示模式框时，我希望将光标放置在 txtFirst 文本框中。
我该怎么做？我以前在使用 registerscript 命令时遇到过麻烦，所以如果需要的话，我希望语法（如果您提供的话）是正确的。
谢谢

另外，我如何更改上面的代码，以便通过选择下拉列表项来显示模式对话框？如果我设置 targetcontrolid="DropDownList1"，则对话框会在放下时显示，而不是在进行选择时显示
When the user pushes the Button, I'd like to display a modal dialog box to capture a couple of values from text boxes and submit these values to the server.
When the modal box is shown, I'd like the cursor to be placed in the txtFirst textbox.
How do I do this? I've had trouble with registerscript commands before, so if one is needed, I hope the syntax, if you provide it, is correct.
Thanks

Also, how could I change the above code so that the modal dialog was displayed as a result of a selection of a dropdownlist item? If I set the targetcontrolid="DropDownList1", the dialog box is display when it drops rather than when a selection is made
