解决方案

< blockquote>你有AutoPostBack = True的所有文本框，但为什么？

如果它的要求及其发生在y上然后你正在处理每个文本框的textchange事件处理程序，你已经知道回发后哪个文本框应该有光标。您可以使用javascript来设置焦点。只需创建一个使用Page.RegisterClientScriptBlock注册客户端脚本的函数。

Javascript函数示例：

在保存按钮代码中添加：

  protected   void  BtnSave_Click（ object  _ObjSender，EventArgs e）
 {
 尝试 
 {
 TxtFirstTextBox.Focus（）; 
} 
  catch  
 {
 
} 
}

解决方案

You have all text boxes with AutoPostBack=True, but Why?
If its the requirement and its happening on your page then you are handling each textbox's textchange event handler and you already know which text box is should have the cursor after postback. You can use javascript to set the focus. Just create a function which registers client script using Page.RegisterClientScriptBlock.

Hi,

On your save button code add this:

protected void BtnSave_Click(object _ObjSender, EventArgs e)
      {
          try
          {
           TxtFirstTextBox.Focus();
          }
          catch
          {

          }
      }
