C#递归遍历窗体所有textbox控件并设置textbox事件的方法


本文向大家介绍C#递归遍历窗体所有textbox控件并设置textbox事件的方法,包括了C#递归遍历窗体所有textbox控件并设置textbox事件的方法的使用技巧和注意事项,需要的朋友参考一下

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。
