The following is the procedure for adding a non-existent record using an AutoCompleteBox.
Step 1
Open the Solution Explorer.
Step 2
In the Solution Explorer, right-click on the Server and choose "Add Table".

In this way we will add two tables (one is a Student table and another one is College table). The table appears.
Student Table:
College Table:
Step 4
Go to the menu bar, click the "Add Relationship" button.
The "Add New Relationship" dialog box appears on the screen. In that, establish a many to zero or one relationship between the two tables.
Step 5
In the Solution Explorer, right-click on the Screens and choose "Add Screen".
Step 6
The Add New Screen dialog box appears. Select the "Editable Grid Screen" from the Screen Template, under screen information, choose "Colleges" under the screen data and provide a name to the Screen and click the "OK" button.
Step 7
Once again add a "New Data Screen" and from the Screen Template, under screen information, choose "Student" under screen data and provide a name for the Screen and click the "OK" button.
Step 8
Add "System.Windows.Controls.Input" to the client project by switching to "File View" in Solution Explorer.

In the Solution Explorer, right-click on the Client folder and choose "Add Reference".
Select "System.Windows.Controls.Input" from the "Reference Manager-Client" dialog box and click "OK".

Click on "Write Code" and choose the "_created" method.
Add the following code:

{
// Write your code here.
this.StudentProperty = new Student();
