我正在使用TextBox的OnTextChanged事件,如果它失去焦点,则会在后面运行代码,第一次加载页面时,它会触发后面的代码。但是,在第一次运行后台代码后,如果我返回到文本框并使其再次失去焦点,它不会再执行任何代码。每次失去焦点时,如何使文本框触发代码。
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<telerik:RadTextBox ID="uiToLocation" runat="server" Width="100%" AutoPostBack="true"
OnTextChanged="uiToLocation_Leave" EmptyMessage="<%$ Resources:ResourceHKEx,Arrive_To %>" />
</ContentTemplate>
</asp:UpdatePanel>
后面的代码,主要是aspx.cs
using System;
using System.Collections.Generic;
using System.Configuration;
using System.Data;
using System.Diagnostics;
using System.Globalization;
using System.Linq;
using System.Net.Http;
using System.Text;
using System.Threading;
using System.Web;
using System.Web.UI;
using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls;
using Telerik.Web.UI;
namespace WebHKEx
{
public partial class FlightEdit : Web.CustomPage
{
protected void Page_Init(object sender, EventArgs e)
{
// initialize variables
InitializeVariables();
// permission checking
VerifyUserPermissions(true);
// initialize controls
InitializeControls();
}
protected void Page_Load(object sender, EventArgs e)
{
}
protected void Page_UnLoad(object sender, EventArgs e)
{
}
} // end class
} // end namespace
后面的代码在一个子控件cs文件中。
using System;
using System.Collections.Generic;
using System.Data;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using Telerik.Web.UI;
namespace WebHKEx.WebControls
{
public partial class UsageControl2SubControl1 : System.Web.UI.UserControl
{
protected void Page_Load(object sender, EventArgs e)
{
if (Convert.ToBoolean(uiRemoved.Value))
{
this.Visible = false;
}
}
protected void uiToLocation_Leave(object sender, EventArgs e)
{
uiDistance = "123";
}
}// end class
}// end namespace
