Textbox with Autocomplete on Windows Phone 7 (Facebook style)

[Roakman]

I have observed the Windows Phone 7 Beta SDK and i am having a simple query or you may consider it as a suggestion as well. Actually is it possible to have a Textbox with an autocomplete property on Windows Phone 7. If you are not getting my query then it would be better to checkout the facebook where the textbox reacts in the manner which i am talking about or there would be an additional search button next to the Textbox.

I guess my problem is much similar with yours. I am having a ListBox which has been composed of a datatable with two columns, one with primary key (ValueMember), the other with the display name (DisplayMember).
The goal is to achieve the autocompletion textbox via the list.
Following code level where you can see that the research is based on what you type. Only problem i am facing while concatenating my textbox with autocomplete but still it remains white. Finally when I apply this same code then everything works fine, actually I do not know how to display text to return.

Private Sub Form1_Load (ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load 
MyConn.Open () 
MyComm.CommandText = CommandType.Text 
MyComm.CommandText = "SELECT param1, param2, param3 from student order by colname" 
MyCurser = MyComm.ExecuteReader 

data.Columns.Add ("C1") 
data.Columns.Add ("C2", GetType (String)) 
While MyCurser.Read () = True 
data.Rows.Add (MyCurser.GetDecimal (0), MyCurseur.GetString (1)) 
End While 
List1.DataSource = data 
List1.ValueMember = "C1" 
List1.DisplayMember = "C2" 

MyCurser.Close () 
End Sub 
Private Sub Text1_TextChanged (ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Text1.TextChanged 

Try 
Then if AutoComplete 
Sun TextEntered As String = Text1.Text 
Sun iIndex As Integer = List1.FindString (Text1.Text.Trim ()) 
If iIndex> = 0 Then 
AutoComplete = False 
List1.SelectedIndex = iIndex 
List1.TopIndex = iIndex 
Text1.Text = dt.DisplayExpression () 'List1.Columns (0). Text 
AutoComplete = True 
Text1.Select (TextEntered.Length, Text1.Text.Length) 
Else 
List1.SelectedIndex = -1 
End If 
End If 
Catch ex As Exception 
MsgBox (ex.Message) 
End Try 
End Sub 
Private Sub Text1_KeyDown (ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles Text1.KeyDown 

AutoComplete = e.KeyCode <> Keys.Delete And e.KeyCode <> Keys.Back 

End Sub

I think I have got it what you want to do. Add the following code in the Text1 autocomplete, content of List1. Thus, typing a few letters will offer you a list that will appear below it and that will contain the content of List1 is what you have typed earlier in the text1. If this is what you seek, you no longer need the procedure Text1_TextChanged, everything will be done automatically.

Private Sub Form1_Load (ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase. Load 
MyConn.Open () 
MyComm.CommandText = CommandType.Text 
MyComm.CommandText = "SELECT param1, param2, param3 from student order by colname" 
Mycurser = MyComm.ExecuteReader 

data.Columns.Add ("C1")
data.Columns.Add ("C2", GetType (String)) 

While MyCurser.Read () = True 
dt.Rows.Add (MyCurser.GetDecimal (0), MyCurser.GetString (1)) 
End While 

List1.DataSource = dt 
List1.ValueMember = "C1" 
List1.DisplayMember = "C2" 

MyCurser.Close () 
'Start Editing Code 
Sun Pass As New System.Windows.Forms.AutoCompleteStringCollection 
For Each Str As String In List1.Items 
col.Add (Str) 
Next 
Text1.AutoCompleteCustomSource = col 
Text1.AutoCompleteMode = AutoCompleteMode.Suggest 
Text1.AutoCompleteSource = AutoCompleteSource.CustomSource 
'End of code change 
End Sub

Here i have given the syntax to declare the textbox with an Autocomplete property. If you are using .VB then the code is as follows.

<ThemeableAttribute(False)> _
Public Overridable Property AutoCompleteType As AutoCompleteType
	Get
	Set

<asp:TextBox AutoCompleteType="AutoCompleteType" />

If you are using "C#" then :

[ThemeableAttribute(false)]
public virtual AutoCompleteType AutoCompleteType { get; set; }

<asp:TextBox AutoCompleteType="AutoCompleteType" />

If you are using C++ then :

[ThemeableAttribute(false)]
public:
virtual property AutoCompleteType AutoCompleteType {
	AutoCompleteType get ();
	void set (AutoCompleteType value);
}

<asp:TextBox AutoCompleteType="AutoCompleteType" />

If you are using F# then :

[<ThemeableAttribute(false)>]
abstract AutoCompleteType : AutoCompleteType with get, set
[<ThemeableAttribute(false)>]
override AutoCompleteType : AutoCompleteType with get, set

<asp:TextBox AutoCompleteType="AutoCompleteType" />
