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：

复制代码 代码如下:/// <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。
