Your question does not make a lot of sense. What information do you want in the second textbox?

Graeme_Grant 8-Dec-22 6:53am

probably area code & number ...

Richard MacCutchan 8-Dec-22 6:55am

Possibly, but that would still make little sense.

I know, but we are talking about beginners. But now resolved.

Int cont;
cont = text box.text;
I want to assign both textbox for same variable name .is it possible?

Yes, you could do something like:

string contact = textbox1.Text;
contact += ";";
contact += textbox2.Text;

I tried ,
cont = textbox1.text.trim() +textbox2.text.trim();
And
cont = textbox1.text.trim() , textbox2.text.trim();

Like that but it not work

Your cont variable needs to be string not an int type.

Of course you can, and there are many ways.
But a contact number (telephone number?) is not a number (think of 1-800-FLOWERS) so don't try to store them in a numeric value.
Use a string, possibly formatted as XML or JSON or similar.

I would suggest that the best solution would be to change the DB: add a table which holds a contact number, and a Foreign Key back to your original table.

You can that add multiple contact number to a single contact, and retrieve them using a JOIN clause.

The other solution is to hope the existing field is defined as NVARCHAR and long enough to hold many contact numbers, then store your text boxes as commas separated data. That gets really messy later though and it's normally a good way to get some really hair pulling problems when you start modifying your app later.

Remember, many people have multiple contact numbers: home, work, mobile, work mobile, whatsapp, ... restricting this to two is probably a bad idea.
