我有这个方法，我在按钮点击事件上调用此方法来清除表单数据



这是我的方法

I have this method and i call this method on a button click event to clear the forms data

Here is my method

public static void ClearFields(ControlCollection pageControls)
    {
        foreach (Control contl in pageControls)
        {
            string strCntName = (contl.GetType()).Name;

            switch (strCntName)
            {
                case "TextBox":
                    TextBox tbSource = (TextBox)contl;
                    tbSource.Text = "";
                    break;
                case "RadioButtonList":
                    RadioButtonList rblSource = (RadioButtonList)contl;
                    rblSource.SelectedIndex = -1;
                    break;
                case "DropDownList":
                    DropDownList ddlSource = (DropDownList)contl;
                    ddlSource.SelectedIndex = -1;
                    break;
                case "ListBox":
                    ListBox lbsource = (ListBox)contl;
                    lbsource.SelectedIndex = -1;
                    break;
            }
            ClearFields(contl.Controls);
        }
    }

点击按钮即可调用此方法follow \

    {
        ClearFields(Form.Controls);
    }

您好b $ b

如果您想清除某些控件值，请转到客户端脚本。

我给出了符合你要求的虚拟场景。

Hi
If you want to clear certain controls value then go for Client Side Scripts.
I have given a dummy scenario which matches your requirements.

<asp:CheckBox ID="CheckBox1" Text="Check Item" Checked="true"  runat="server" />
<asp:RadioButton ID="RadioButton1" Text="Radio Item" Checked="true" runat="server" />
<asp:TextBox ID="TextBox1"   runat="server" TextMode="MultiLine"></asp:TextBox>
<asp:Button ID="Button1" runat="server" Text="Button" OnClientClick="ClearAll()" />

和脚本是

and the script is

<script src="//ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<script type="text/javascript">
    function ClearAll() {
