问题描述
我是asp.net的新手，这个问题似乎很傻，但是我真的不知道出什么问题了.
我在清除文本框时遇到问题.
我尝试了textbox.text=string.empty，textbox.text=""，但是这些似乎都没有帮助，只是没有清除文本框.
有人可以告诉我是否在代码中设置了不允许我清除文本框的内容吗?
Hi,
I am new to asp.net.and this question seems pretty silly, but I really can''t figure out what is wrong.
I am having an issue with clearing the textbox.
I tried textbox.text=string.empty, textbox.text="" but none of these seem to help, the textbox just doesn''t get cleared.
Can someone tell me if I have set something in the code that''s not allowing me to clear the textbox?
<asp:TextBox ID="TextBox3" runat="server" Width="177px" ontextchanged="TextBox3_TextChanged" Height="16px" style="margin-left: 5px"></asp:TextBox>
protected void Button11_Click(object sender, EventArgs e)
{
Panel1.Visible = false; DropDownList5.ClearSelection();
TextBox3.Text = string.Empty;
}

问题对我来说看起来很奇怪..，
可能是您未将所有控件设置为运行服务器
这是我在PC上完成的代码
Problem Looking Strange For me..,
May be your all controls not set as runat server
here is the code i am providing just done on my PC
protected void Button1_Click(object sender, EventArgs e)
{
TextBox1.Text = String.Empty;
TextBox2.Text = String.Empty;
}
HTML代码
HTML Code
<body>
<form id="form1" runat="server">
<div>
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox><asp:TextBox ID="TextBox2"
runat="server"></asp:TextBox><asp:Button ID="Button1" runat="server"
Text="Button" onclick="Button1_Click" />
</div>
</form>
</body>
它对我有用....

DropDownList1.ClearSelection();
}//this for clear thr dropdownlist
