检测聚焦文本框 [英] detect the focused textbox

问题描述

嗨朋友，



我有10个文本框和一个按钮，考虑到我的光标在第5个文本框中闪烁。当我点击按钮时，我应该找到光标所在的文本框并在该文本框中写入一些文本..我不知道如何检测聚焦文本框..

解决方案

你无法检测到之前聚焦的文本框 - 因为它不再被聚焦 - 但你可以处理TextBox.Leave事件并设置一个变量来告诉你它是哪一个。

  private  TextBox lastLeft; 
  private   void  myTextBoxes_Leave（ object  sender，EventArgs e）
 {
 lastLeft = sender  as  TextBox; 
} 

它可能被索引为0或1，检查html代码！

修改所有索引控件...

Hi Friends,

I have some 10 number of textbox and a button, consider my cursor is blinking in 5th textbox. when i click the button ,i should find in which textbox the cursor was and write some text in that textbox.. i dono how to detect the focused textbox..

解决方案

You can''t detect the previous focussed textbox - because it is no longer focussed - but you can handle the TextBox.Leave event and set a variable to tell you which one it was.

private TextBox lastLeft;
private void myTextBoxes_Leave(object sender, EventArgs e)
    {
    lastLeft = sender as TextBox;
    }

It''s possibly indexed as 0 or 1, check html code!
Modify all indexed controls...
