[Solved] AutoComplete List Selection is Not Appearing

[Patrick]

Hello, 

I have this in my aspx page:

<telerik:RadAutoCompleteBox
         ID="MyControl" runat="server" Width="400" DropDownHeight="150"
         DropDownWidth="500"
         SelectMethod="MySelectMethod"
         InputType="Text">
     </telerik:RadAutoCompleteBox>

             

In my code-behind, I have this:

01.Public Function MySelectMethod() As AutoCompleteBoxData
02.    Dim data As DataTable = GetChildNodes("a", "139")
03.    Dim result As New List(Of AutoCompleteBoxItemData)()
04.
05.    For Each row As DataRow In data.Rows
06.        Dim childNode As New AutoCompleteBoxItemData()
07.        childNode.Text = row("field1").ToString()
08.        childNode.Value = row("field2").ToString()
09.        result.Add(childNode)
10.    Next
11.
12.    Dim res As New AutoCompleteBoxData
13.    res.Items = result.ToArray()
14.
15.    Return res
16.End Function
17.
18.Private Function GetChildNodes(ByVal searchString As String, ByVal countryList As String) As DataTable
19.    ' Some code that works
20.End Function
21.
22.Private Function GetData(selectCommand As SqlCommand) As DataTable
23.    ' Some code that works
24.End Function

MySelectMethod is returning the records that I am expecting, given that the parameters are hardcoded. However this are the problems that I encounter:

1) The list of records is not appearing. 
2) My text-input goes away after getting the list of records
3) MyControl.Text property is empty

Anyhelp on this one? I badly need specifically #3 since it is a parameter that I need to pass dynamically.

Hello John,

The SelectMethod is an inherited method from the WebControl and instead of using it for populating the control with data, you should directly specify the DataSource with the needed data. Please refer to the following online demo and documentation article, providing more details on the matter :
