首先看下面的aspx:
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm4.aspx.cs" Inherits="Amlak.WebForm4" %>
<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>
<!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:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<div>
<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">
<AjaxSettings>
<telerik:AjaxSetting AjaxControlID="RadComboBox1">
<UpdatedControls>
<telerik:AjaxUpdatedControl ControlID="CheckBox1" UpdatePanelRenderMode="Inline" />
</UpdatedControls>
</telerik:AjaxSetting>
</AjaxSettings>
</telerik:RadAjaxManager>
<telerik:RadComboBox ID="RadComboBox1" runat="server" AutoPostBack="True" AppendDataBoundItems="True"
OnSelectedIndexChanged="RadComboBox1_SelectedIndexChanged">
<Items>
<telerik:RadComboBoxItem runat="server" Text="1" Value="1" />
<telerik:RadComboBoxItem runat="server" Text="2" Value="2" />
<telerik:RadComboBoxItem runat="server" Text="3" Value="3" />
<telerik:RadComboBoxItem runat="server" Text="4" Value="4" />
</Items>
</telerik:RadComboBox>
<br />
<br />
<asp:CheckBox ID="CheckBox1" runat="server" AutoPostBack="True" OnCheckedChanged="CheckBox1_CheckedChanged"
Text="Check Me" TextAlign="Left" />
<br />
<br />
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
</div>
</form>
</body>
</html>
我后面的代码是这样的:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
namespace Amlak
{
public partial class WebForm4 : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
protected void RadComboBox1_SelectedIndexChanged(object sender, Telerik.Web.UI.RadComboBoxSelectedIndexChangedEventArgs e)
{
if (RadComboBox1.SelectedItem.Value == "2")
{
CheckBox1.Checked = true;
}
else
{
CheckBox1.Checked = false;
}
}
protected void CheckBox1_CheckedChanged(object sender, EventArgs e)
{
if (CheckBox1.Checked)
{
TextBox1.Text = "text";
}
else
{
TextBox1.Text = "";
}
}
}
}
我的目标:
我想强制
RadComboBox1
在 AJAX 模式下工作并通过后面代码中定义的条件更改 CheckBox1.Checked。-> 不希望为此回发。我想强制
CheckBox1
在 PostBack 模式下工作并更改TextBox1.text
后面代码中定义的条件。-> 我想要回发这个。
在这种情况下 - >RadComboBox1
工作正常
,但我不知道为什么OnCheckedChanged="CheckBox1_CheckedChanged"
当我们更改检查时不触发CheckBox1
!(因为我们将它添加为RadComboBox1
In的更新RadAjaxManager1
)。
我的问题:
我应该添加RadComboBox1
为更新RadComboBox1
吗?但是,如果不添加它,它可以正常工作。
如果我们添加ChechBox1
到RadAjaxManager1
如下:
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm4.aspx.cs" Inherits="Amlak.WebForm4" %>
<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>

<telerik:AjaxUpdatedControl ControlID="CheckBox1" UpdatePanelRenderMode="Inline" />
</UpdatedControls>
</telerik:AjaxSetting>
<telerik:AjaxSetting AjaxControlID="CheckBox1">
<UpdatedControls>
<telerik:AjaxUpdatedControl ControlID="TextBox1" />
</UpdatedControls>
</telerik:AjaxSetting>
</AjaxSettings>
</telerik:RadAjaxManager>
<telerik:RadComboBox ID="RadComboBox1" runat="server" AutoPostBack="True" AppendDataBoundItems="True"
OnSelectedIndexChanged="RadComboBox1_SelectedIndexChanged">
<Items>
<telerik:RadComboBoxItem runat="server" Text="1" Value="1" />
<telerik:RadComboBoxItem runat="server" Text="2" Value="2" />
<telerik:RadComboBoxItem runat="server" Text="3" Value="3" />
<telerik:RadComboBoxItem runat="server" Text="4" Value="4" />
</Items>
</telerik:RadComboBox>
<br />
<br />
<asp:CheckBox ID="CheckBox1" runat="server" AutoPostBack="True" OnCheckedChanged="CheckBox1_CheckedChanged"
Text="Check Me" TextAlign="Left" />
<br />
<br />
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
</div>
</form>
</body>
</html>
所以它在 AJAX 模式下工作正常,但我想强制CheckBox1
在 PostBack 中工作!
我该如何解决这个问题?
我应该添加TextBox1
作为更新RadComboBox1
还是RadAjaxManager
不添加?
感谢您关注我的问题。最好的祝福
