c# - Executing code when a tab is shown -

i want operations on tab when shown.

example:

textbox1.selectionstart = textbox1.text.length; textbox1.scrolltocaret(); textbox3.selectionstart = textbox3.text.length; textbox3.scrolltocaret(); textbox2.selectionstart = textbox2.text.length; textbox2.focus(); 

where should place code it's done properly?

the events tabcontrol1_selecting, tabcontrol1_selected , tabpage2_enter not work beause occur before tab shown.

i know first tab must shown , code must executed.

try in selectedindexchanged event ,

private void yourtabcontrol1_selectedindexchanged(object sender, eventargs e) {             textbox1.selectionstart = textbox1.text.length;            textbox1.scrolltocaret();            textbox3.selectionstart = textbox3.text.length;            textbox3.scrolltocaret();            textbox2.selectionstart = textbox2.text.length;            textbox2.focus();                  }
