Solution 1

You don't have to write any code for this.
The Operating System is taking care of automatically.
Just press the delete key while in any TextBox, and the character after the insersion point will get deleted. It's that simple.
So, the code is this:

Solution 2

The functionality of the textbox is inherent, you do not need to do anything special when the text box has focus.

If the textbox does not have focus, you will need to handle the keypress event, read which key is pressed and then trim the textbox by 1 char.

Have a go at writing some code yourself, and ask a specific question when you have a problem.

hai
Thanks for u r response
could u please tell me pressing delete key from keyboard ,
is it keydown event or keypress event

DaveAuld 7-Sep-10 7:35am

Try it yourself, look at the event arg e; they give you different things, you also have a keyUp event which can be used.

sKumarnvs 7-Sep-10 7:43am

Thnanks for ur answer i will try it

sKumarnvs 7-Sep-10 7:55am

Thnak u very much i can handle delete key in KeyUp event but could u please tell me hoe can i delte a char at the cursor points.

DaveAuld 7-Sep-10 8:02am

Look at the textbox members, you will see something that relates to selected start position or similiar, this is the position of the cursor. you will need to remove that char for the char array for the text, or manipulate it using a loop.

sKumarnvs 7-Sep-10 8:12am

Thanks could u please tell me sample code.

DaveAuld 7-Sep-10 8:13am

No, have a go yourself......i do not know what members there are for textboxext and the rest is basic string manipulation, surely you can attempt that.

sKumarnvs 7-Sep-10 8:22am

Thanks sir thank you very much i will try for this
