focus（）不是切换 [英] focus() is not switching

问题描述

在选择 Enter键时，系统应执行以下操作并将焦点切换为

 txt_Interest.Text; 
 

然而事实并非如此。我该如何更正？



谢谢

  protected   void  txt_Principal_TextChanged（ object  sender，
 EventArgs e）
 {
  decimal  Kprincipal = Convert.ToDecimal（txt_Principal.Text）; 
 
 txt_Principal.Text = Kprincipal.ToString（  N）; 
 txt_Interest.Focus（）; 
} 

解决方案

尝试

 txt_Interest.Select（）; 

希望这会有所帮助，

On selecting the Enter key the system should do the following and switch focus to

txt_Interest.Text;

However it doesn't. How do I correct this?

Thanks

protected void txt_Principal_TextChanged ( object    sender, 
                                           EventArgs e)
     {
     decimal Kprincipal = Convert.ToDecimal ( txt_Principal.Text );

     txt_Principal.Text = Kprincipal.ToString( "N" );
     txt_Interest.Focus ( );
     }

解决方案

Try

txt_Interest.Select();

Hope this helps,
