I need AutoComplete functionality for RadTextBoxControl that will allow me to identify the object selected by the user.
Public Class Person
Public Property GuidPerson As Guid
Public Property FirstName As String
Public Property LastName As String
Public ReadOnly Property FullName As String
Get
Return String.Format("{0} {1}", FirstName, LastName)
End Get
End Property
Public Sub New(fName As String, lname As String)
GuidPerson = Guid.NewGuid
FirstName = fName
LastName = lname
End Sub
End Class
Public Class RadForm4
Private listPerson As New List(Of Person)
Public Sub New()
InitializeComponent()
listPerson.Add(New Person("John", "Snow"))
listPerson.Add(New Person("Arya", "Stark"))
listPerson.Add(New Person("Brandon", "Stark"))
listPerson.Add(New Person("Catelyn", "Stark"))
RadTextBoxControl1.AutoCompleteMode = AutoCompleteMode.Suggest
RadTextBoxControl1.AutoCompleteDataSource = listPerson
RadTextBoxControl1.AutoCompleteDisplayMember = "FullName"
End Sub
Private Sub RadButton1_Click(sender As Object, e As EventArgs) Handles RadButton1.Click
'HOW TAKE 'GuidPerson' from selected item in RadTextBoxControl1
End Sub
End Class
How to capture a user-selected object?
For example, in RadDropDownList I would do it like this:
Dim searchValue As Person = TryCast(RadDropDownList1.SelectedItem.DataBoundItem, Person)I don't want to use RadAutoCompleteBox because I want to display the results text and not tokens

Hi Jacek,
To extract the Person object and get the GUID value, you can subscribe to the SelectedIndexChanged event of the RadTextBoxControl.ListElement. You can use the ListElement property and its Items collection which gets the auto-complete items which DataBoundItem property stores the respective Person.
AddHandler Me.RadTextBoxControl1.ListElement.SelectedIndexChanged, AddressOf ListElement_SelectedIndexChanged
Private Sub ListElement_SelectedIndexChanged(ByVal sender As Object, ByVal e As Telerik.WinControls.UI.Data.PositionChangedEventArgs)
If e.Position > -1 Then
Dim p As Person = TryCast(Me.RadTextBoxControl1.ListElement.Items(e.Position).DataBoundItem, Person)
Me.Text = p.GuidPerson.ToString()
End If
End Sub
I am sending you the example project as well!
Hope this helps you!

Hi Jacek,
Thank you for the code snippet.
The RadTextBoxControl doesn't have the SelectedItem property as the DropDownList as you wrote. One way to get the GUID from the selected item in RadTextBoxControl is to use LINQ query to iterate the List collection. I am sending you a code snippet for this written in the button, where you left the comment.
Private Sub radButton1_Click(ByVal sender As Object, ByVal e As EventArgs)
Dim text = radTextBoxControl1.SelectedText
Dim person = listPerson.FirstOrDefault(Function(x) x.FullName = text)
Dim guid = person.GuidPerson
End SubI am sending you a project as well.
I hope this helps.

Hi Maria,
Thank you for your code, however this may cause a bug with two records of the same value.
I made my example based on the Name and Surname to explain the problem more easily, but in the case of e.g. company names, there is a possibility of two records with the same name.
Is there another solution to the problem? For example, I was looking for the option to disable tokens in RadAutoCompleteBox but I did not find such a setting.
