You could concatenate two TextBoxes as the following:
TextBox1 + TextBox2
There is a better way to do so. If it is not that important requirement, you could save them in individual columns and in the front-end, you could concatenate like the following:
<asp:label id="label1" runat="server" text='<%#eval("countrycode")+ " " + eval("phoneno")%>' >
In the Label control, two column values are retrieved with concatenation.
