使用此功能

Use this Function

public void ClearTextBoxes(Control control)
{
foreach (Control c in control.Controls)
{
if (c is TextBox)
{
((TextBox)c).Clear();
}
if (c.HasChildren)
{
ClearTextBoxes(c);
}
}
}

您可以使用以下功能恢复控件

You can use following function to restore the control

public static void ResetControl(Page mypage) 
    { 
        Control myForm = mypage.FindControl("Form1"); 
        foreach (Control ctrl in myForm.Controls) 
        { 
            //Clears TextBox 
            if (ctrl is System.Web.UI.WebControls.TextBox) 
            { 
                (ctrl as TextBox).Text = string.Empty; 
            } 
 
 
            //Clears DropDown Selection 
            if (ctrl is System.Web.UI.WebControls.DropDownList) 
            { 
                (ctrl as DropDownList).ClearSelection(); 
            } 
 
 
            //Clears ListBox Selection 
            if (ctrl is System.Web.UI.WebControls.ListBox) 
            { 
                (ctrl as ListBox).ClearSelection(); 
            } 

            //Clears CheckBox Selection 
            if (ctrl is System.Web.UI.WebControls.CheckBox) 
            { 
                (ctrl as CheckBox).Checked = false; 
            } 
 
 
            //Clears RadioButton Selection 
 
 
            if (ctrl is System.Web.UI.WebControls.RadioButtonList) 
            { 
                (ctrl as RadioButtonList).ClearSelection(); 
            } 
 
 
            //Clears CheckBox Selection 
            if (ctrl is System.Web.UI.WebControls.CheckBoxList) 
            { 
                (ctrl as CheckBoxList).ClearSelection(); 
            } 
        }
