.aspx頁只拉一個TextBox控件:
復制代碼 代碼如下:
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
</head>
<body>
<form id="form1" runat="server">
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
</form>
</body>
</html>
.aspx.cs頁中,首選在Page_Init事件,為TextBox注冊OnBlur事件:
復制代碼 代碼如下:
protected void Page_Init(object sender, EventArgs e)
{
this.TextBox1.Attributes.Add("onblur", Page.ClientScript.GetPostBackEventReference(this.TextBox1, "OnBlur"));
}
寫一個onBlue事件,將替代LinkButton的Click事件:
復制代碼 代碼如下:
private void OnBlurHandle(string ctrl, string args)
{
if (ctrl == this.TextBox1.UniqueID && args == "OnBlur")
{
//這裡寫提交到數據庫中
}
}
然後在網頁的Page_Load事件,判斷是否IsPostBack。
復制代碼 代碼如下:
protected void Page_Load(object sender, EventArgs e)
{
if (IsPostBack)
{
var ctrl = Request.Params[Page.postEventSourceID];
var args = Request.Params[Page.postEventArgumentID];
OnBlurHandle(ctrl, args);
}
}
