c# - Selecting/Highlighting certain text in textbox -

so have textbox time in it, looks this;

when click in textbox, , click on hr part, this;

it should this;

same goes minutes, when @ min part of textbox this;

it should then;

basically trying create programme select/highlight time you. depending on you've clicked on.

what have tried far this;

what should happen when "select" hr part:

textbox1.selectionstart = 0; // start of selection textbox1.selectionlength = 2; //untill ":" seperates hours minutes

this works, text selected thirth picture.

and part:

textbox1.selectionstart = 3; // start of selection, in case after ":" textbox1.selectionlength = textbox1.text.length; //untill end

i know should able write simple if-statement this.

but problem is, how can check part "cursor" at, in textbox?

with selection start can know cursor @ in textbox.

private void textbox1_mouseclick(object sender, mouseeventargs e) { if (textbox1.selectionstart < 3) { textbox1.selectionstart = 0; textbox1.selectionlength = 2; } else if (textbox1.selectionstart > 2) { textbox1.selectionstart = 3; textbox1.selectionlength = textbox1.text.length; } }

if if-statement true, select text, illustration if selectionstart 0, means @ origin of textbox, first 2 digits highlighted.

it should work 2 if-statements.
