本文实例讲述了C#递归遍历窗体所有textbox控件并设置textbox事件的方法。分享给大家供大家参考。具体实现方法如下：
/// <summary>
///
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
public virtual void SetTextBoxOnEnterStyle(object sender, EventArgs e)
{
if (sender is TextBox)
{
TextBox tbox = sender as TextBox;
if (!tbox.ReadOnly)
{
tbox.BackColor = Color.Yellow;
}
}
}
/// <summary>
///
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
public virtual void SetTextBoxOnLeaveStyle(object sender, EventArgs e)
{
if (sender is TextBox)
{
TextBox tbox = sender as TextBox;
if (!tbox.ReadOnly)
{
tbox.BackColor = Color.White;
}
}
}
/// <summary>
///
/// </summary>
/// <param name="frm"></param>
public virtual void SetFormTextBoxControlStyle(Form frm)
{
IterateControlsSetTextBox(frm.Controls);
}
/// <summary>
///
/// </summary>
/// <param name="ctls"></param>
public virtual void IterateControlsSetTextBox(Control.ControlCollection ctls)
{
foreach (Control control in ctls)
{
if (control is TextBox)
{
(control as TextBox).Enter += new EventHandler(SetTextBoxOnEnterStyle);
(control as TextBox).Leave += new EventHandler(SetTextBoxOnLeaveStyle);
}
if (control.Controls.Count > 0)
{
IterateControlsSetTextBox(control.Controls);
}
}
}
希望本文所述对大家的C#程序设计有所帮助。
