C# 方法重置groupBox中的成员

groupBox是否有任何方法可以清除groupBox中对象的所有属性。例如，清除所有文本框，取消选中所有复选框等，并将它们设置为默认值。或者我应该一个接一个地编码来清除它们？我想在事件列表视图SelectedIndexChanged上执行此操作

好的，谢谢你的重播，我发现你可以很简单地选择groupbox里面的控件

        foreach (Control ctrl in groupBox2.Controls)//this will only select controls of groupbox2
        {
            if (ctrl is TextBox)
            {
                (ctrl as TextBox).Text = "";
            }
            if (ctrl is CheckBox)
            {
                (ctrl as CheckBox).Checked = false;
            }
            if (ctrl is ComboBox)
            {
                (ctrl as ComboBox).SelectedIndex = -1;
            }
            //etc
        }

您需要逐个清除组框中的所有控件。

最快的方法是：

Control myForm = Page.FindControl("Form1");
foreach (Control ctrl in myForm.Controls)
{
    //Clears TextBox
    if (ctrl is System.Web.UI.WebControls.TextBox)
    {
        (ctrl as TextBox).Text = "";
    }
    //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();
    }
}

您必须创建如下函数：

private void ClearControls(Control control)
{
    var textbox = control as TextBox;
    if (textbox != null)
        textbox.Text = string.Empty;

    var dropDownList = control as DropDownList;
    if (dropDownList != null)
        dropDownList.SelectedIndex = 0;

    // And add any other controls
    // ...

    foreach( Control childControl in control.Controls )
    {
        ClearControl( childControl );
    }
}

ClearControls(this);

就这样说吧：

private void ClearControls(Control control)
{
    var textbox = control as TextBox;
    if (textbox != null)
        textbox.Text = string.Empty;

    var dropDownList = control as DropDownList;
    if (dropDownList != null)
        dropDownList.SelectedIndex = 0;

    // And add any other controls
    // ...

    foreach( Control childControl in control.Controls )
    {
        ClearControl( childControl );
    }
}

ClearControls(this);

这将以递归方式工作，因此，如果您有任何面板（例如，有自己的控件集要清除），这也将清除这些面板。

我已编辑了您的标题。请看，“，其中的共识是“不，他们不应该”。好的，谢谢你的信息，我下一步不会这么做@约翰索克。我想确保在我编写一堆你知道的代码之前没有任何方法没有Page.FindControl（）方法。除了在元素中？还是我弄错了什么？
