回发后如何清除文本框值 [英] How to clear text box values after postback

问题描述

大家好，
我有一个网络表单，我在其中保存个人信息时提交了姓名，年龄等个人信息.我清除了文本框的值.我也对文本框的查看状态进行了伪造.但是如果我输入了名称并保存了amit第二次，如果我再次填写信息，例如arvind之类的名称，则amit名称也将落在此处.如何在回发后清除先前的值

推荐答案

转到屏幕的设计页面，您可以找到
FORM标签.

您可以找到AutoComplete属性.然后将该值设置为"OFF".
就是这样.

如果此属性未在您的页面中显示，也可以手动编写此属性.

问候，
Kiran.

Hi,

Go to the design page of your screen,there you can find the
FORM tag.

You can find the AutoComplete property.Then set that value as "OFF".
Thats it.

If this property is not showing in your page also just write this property manually.

Regards,
Kiran.

Use AutoCompleteType property of text box.<br />
<asp:TextBox ID="TextBox1" AutoCompleteType="disabled" runat="server"></asp:TextBox>

使用此功能

Use This Function

public void EmptyControlData(Control parent)
    {
        foreach (Control c in parent.Controls)
        {
            if ((c.GetType() == typeof(TextBox)))
            {
                ((TextBox)c).Text = "";
            }
            if ((c.GetType() == typeof(DropDownList)))
            {
                ((DropDownList)c).SelectedIndex = -1;
                //((DropDownList)c).Items.Clear();
            }
            if (c.HasControls())
            {
                EmptyControlData(c);
            }
        }
    }
