1. Slide the mouse over the textbox to select all
Front-end:
Back-end:
this.txtbox1.Attributes.Add("onMouseOver", "this.focus(); this.select();");
2. Get focus
Backend:
textbox1.Focus();
textbox1.Attributes.Add("onfocus","this.select()");
The above introduces the implementation of always in my heart Aspnet text box selection, including the content of always in my heart. I hope it will be helpful to friends who are interested in PHP tutorials.
