TextBox TextChanged事件未正确触发 [英] TextBox TextChanged Event Is not Firing Properly

嗨！
我正在Asp.net中制作模块，也正在使用更新面板"和母版页".

Hi!
I am making a module in Asp.net and i am using Update Panel and Master Pages also.
I have a TextBox and on it''s TextChanged Event i am calculating the total time taken.
It is working properly when user enters the text in the textBox manually but when user selects a text from history of the TextBox the event does not fires at all.
What to do Please Help.
Thank You!

推荐答案

使用KeyPress事件.并将您的计算逻辑放在一个方法中.调用TextChanged和KeyPress中的方法.

Use the KeyPress event. And put your calculations logic in a method. Call to the method in TextChanged and KeyPress.

Hope it helps.

仅当文本框的值更改并且光标将从文本框中删除时，才会触发TextChanged事件(请确保文本框的autopostback属性为< blue>真的).无关紧要的是，无论您从哪里选择文本，都可以来自用户键盘或历史记录.

请参阅此以获取更多信息: MSDN:TextBox.TextChanged事件 [ ^ ]

尝试阅读此 [

The TextChanged event will be fired only, when the value of textbox will change and cursor will be removed from textbox(Make sure that autopostback property of textbox is <blue>true). This doesn''t matters that from where you are picking the texts, it can be both from user keyboard or history.

Refer this for more info : MSDN : TextBox.TextChanged Event[^]

Try reading this[^] also.
