asp.net相关控件的客户端及服务器端的禁用和启用

本例包括以下控件的相关示例：

Button,ImageButton,TextBox,

DropDownList,CheckBox,RadioButton

的客户端及服务器端的禁用和启用

以及

LinkButton,HyperLink 的服务器端禁用和启用

和

借助于父控件如td等 来实现

LinkButton,HyperLink 的客户端禁用和启用
----------------------------------------
Button,ImageButton,TextBox,

DropDownList,CheckBox,RadioButton

的客户端及服务器端的禁用和启用

------------------------------------

服务器端 相关代码如下：

//服务器端启用

protected void Button2_Click(object sender, EventArgs e)

{

Button1.Attributes.Remove("disabled");

ImageButton1.Attributes.Remove("disabled");

TextBox1.Attributes.Remove("disabled");

DropDownList1.Attributes.Remove("disabled");
CheckBox1.Attributes.Remove("disabled");

RadioButton1.Attributes.Remove("disabled");

}
//服务器端禁用

protected void Button4_Click(object sender, EventArgs e)

{

Button1.Attributes["disabled"] = "true";

ImageButton1.Attributes["disabled"] = "true";

TextBox1.Attributes["disabled"] = "true";

DropDownList1.Attributes["disabled"] = "true";
CheckBox1.Attributes["disabled"] = "true";

RadioButton1.Attributes["disabled"] = "true";

}
客户端 相关代码如下：
<script language="javascript" type="text/javascript">

//客户端禁用

function ControlDisabled()

{

document.all.Button1.disabled = true;

document.all.ImageButton1.disabled = true;



document.all.TextBox1.disabled = true;

document.all.DropDownList1.disabled = true;



document.all.CheckBox1.disabled = true;

document.all.RadioButton1.disabled = true;

}
//客户端启用

function ControlEnabled()

{

document.all.Button1.disabled = false;

document.all.ImageButton1.disabled = false;



document.all.TextBox1.disabled = false;

document.all.DropDownList1.disabled = false;



document.all.CheckBox1.disabled = false;

document.all.RadioButton1.disabled = false;

}

</script>

-----------------------------

LinkButton,HyperLink 的服务器端 禁用与启用

(不支持对LinkButton的 OnClientClick 事件的禁用)

-------------------------------------------------

<asp:LinkButton ID="LinkButton1" runat="server"

OnClick="LinkButton1_Click" >

LinkButton</asp:LinkButton>

<br />

<asp:HyperLink ID="HyperLink1" runat="server" NavigateUrl="http://www.freeliver.cn" Target="_blank" >

HyperLink</asp:HyperLink>

<br />
服务器端代码：

//LinkButton,HyperLink 服务器端启用

protected void Button2_Click(object sender, EventArgs e)

{

LinkButton1.Enabled = true;

HyperLink1.Enabled = true;

}
//LinkButton,HyperLink 服务器端禁用

protected void Button4_Click(object sender, EventArgs e)

{

LinkButton1.Enabled = false;

HyperLink1.Enabled = false;

}

-----------------------

借助于父控件如td等

来实现 LinkButton,HyperLink 的客户端禁用和启用

--------------------------

<table>

<tr>

<td id="tdLinkButton" onclick="return tdLinkButtonOnClick();">

<asp:LinkButton ID="LinkButton1" runat="server"

OnClick="LinkButton1_Click" >

LinkButton</asp:LinkButton>

</td>

<td id="tdHyperLink" onclick="return tdHyperLinkOnClick();">

<asp:HyperLink ID="HyperLink1" runat="server"

NavigateUrl="http://www.freeliver.cn" Target="_blank" >

HyperLink</asp:HyperLink>

</td>

</tr>

</table>
<script language="javascript" type="text/javascript">

//LinkButton,HyperLink 客户端禁用

function ControlDisabled()

{

document.all.LinkButton1.disabled = true;

document.all.HyperLink1.disabled = true;

}

//LinkButton,HyperLink 客户端启用

function ControlEnabled()

{

document.all.LinkButton1.disabled = false;

document.all.HyperLink1.disabled = false;

}



//tdLinkButton的onclick事件

//如果LinkButton1的disabled==true

//则不响应相关事件

function tdLinkButtonOnClick()

{

if(document.all.LinkButton1.disabled)

{

return false;

}

else

{

return true;

}

}
//tdHyperLink的onclick事件

//如果HyperLink1的disabled==true

//则不响应相关事件

function tdHyperLinkOnClick()

{

if(document.all.HyperLink1.disabled)

{

return false;

}

else

{

return true;

}

}

</script>
