            cs.RegisterStartupScript(this.GetType(), "SendTextBox", "setTimeout('__doPostBack(\'" + txtbox.ID + "\',\'\')', 0);", true);
            base.OnPreRender(e);

推荐答案

请添加Autopostback =对于该Textbox是正确的，那么textchanged事件肯定会起作用。

u可以在该控件的属性中更改它。

Please Add Autopostback=true for that Textbox then the textchanged event will work for sure.
u can change it in the property of that control.

Check some of steps
1. If you have used any requiredfied validato or reqular expression (Client Validation)
Then mention in your textbox property CauseValidation="false"
2. Autopostback="true" in textbox property
Hope this will help you
