On your ASP.Net page, you can use a RequiredFieldValidator to make sure that the user has entered something in the textbox.

<asp:RequiredFieldValidator id="RequiredFieldValidator1" runat="server" ErrorMessage="Please enter your user name." ControlToValidate="UserNameTextBox" Display="Dynamic" />

I would use one textbox and let the user enter either their username or ID.

Then you write a query on the database to SELECT COUNT(*) FROM Users WHERE (UserName = @UserName) OR (UserID = @UserID). Something like that. If COUNT equals zero, there was no match. If COUNT is greater than zero, you have a match.


Use a combo box with two values: ID, Name

Then when user types in textbox, you can check the value selected in combobox, to know whether he is searching by Id or Name
