将表单放在asp.net面板控件中,并使用按钮Id设置其defaultButton属性。请参阅以下代码:
<asp:Panel ID="Panel1" runat="server" DefaultButton="Button1">
<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional">
<ContentTemplate>
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
<asp:Button ID="Button1" runat="server" onclick="Button1_Click" Text="Send" />
</ContentTemplate>
</asp:UpdatePanel>
</asp:Panel>

在aspx页面加载事件中,在框中添加onkeypress
。
this.TextBox1.Attributes.Add(
"onkeypress", "button_click(this,'" + this.Button1.ClientID + "')");
然后添加此javascript以评估按键,如果是“输入”,请单击右键。
<script>
function button_click(objTextBox,objBtnID)
{
if(window.event.keyCode==13)
{
document.getElementById(objBtnID).focus();
document.getElementById(objBtnID).click();
}
}
</script>

Codeproject有一个完整的解决方案:

并且像文章所说:&#34;决定哪种解决方案最适合您的需求&#34;
===================编辑答案========================== ==
上面提到的链接,讨论了两种捕获&#34;输入密钥的方法。事件:
Javascript (将onKeyPress事件绑定到对象并创建一个javascript函数来检查按下了哪个键并执行逻辑)
代码背后的_Page_Load:_
//Add the javascript so we know where we want the enter key press to go
if (!IsPostBack)
{
txtboxFirstName.Attributes.Add("onKeyPress",
"doClick('" + btnSearch.ClientID + "',event)");
txtboxLastName.Attributes.Add("onKeyPress",
"doClick('" + btnSearch.ClientID + "',event)");
}
Javascript代码:
<SCRIPT type=text/javascript>
function doClick(buttonName,e)
{
//the purpose of this function is to allow the enter key to
//point to the correct button to click.
var key;
if(window.event)
key = window.event.keyCode; //IE
else
key = e.which; //firefox
if (key == 13)
{
//Get the button the user wants to have clicked
var btn = document.getElementById(buttonName);
if (btn != null)
{ //If we find the button click it
btn.click();
event.keyCode = 0
}
}
}
</SCRIPT>
面板控制
<asp:Panel ID="panSearch" runat="server" DefaultButton="btnSearch2" Width="100%" >
<asp:TextBox ID="txtboxFirstName2" runat="server" ></asp:TextBox>
</asp:Panel>

请注意,Panel标记有一个名为DefaultButton的属性。你设定 此属性为您要单击的按钮的按钮ID 输入按键事件。所以Panel内的任何文本框都会 将其Enter键按到DefaultButton中设置的按钮 专家小组的财产

仅在html代码中添加一个包含页面控件的面板。在面板内,添加一行DefaultButton =“buttonNameThatClicksAtEnter”。请参阅下面的示例,不需要其他任何内容。
<asp:Panel runat="server" DefaultButton="Button1"> //add this!
//here goes all the page controls and the trigger button
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
<asp:Button ID="Button1" runat="server" onclick="Button1_Click" Text="Send" />
</asp:Panel> //and this too!
答案 4 :(得分:0)
您可以使用javascript / jquery:
<script>
function runScript(e) {
if (e.keyCode == 13) {
$("#myButton").click(); //jquery
document.getElementById("myButton").click(); //javascript
}
}
</script>
<asp:textbox id="txtUsername" runat="server" onkeypress="return runScript(event)" />
<asp:LinkButton id="myButton" text="Login" runat="server" />
答案 5 :(得分:-2)
您可以尝试:
在HTML中:
<asp:TextBox ID="TextBox1" runat="server" onKeyDown="submitButton(event)"></asp:TextBox>
<asp:Button ID="Button1" runat="server" Text="Button" onclick="Button1_Click" />
和javascript:
function submitButton(event) {
if (event.which == 13) {
$('#Button1').trigger('click');
}
}
代码背后:
protected void Button1_Click(object sender, EventArgs e)
{
//load data and fill to gridview
} // fixed the function view for users
