자동 제안 텍스트 상자

Question

특정 문자를 입력 한 후 직원의 이름을 표시하는 자동 제안 텍스트 상자가 필요합니다. 이 이름은 employee 테이블에 firstname, middlename, lastname의 세 컬럼으로 표시됩니다.

나는이 코드를 시도했지만 테이블의 첫 번째 열, 즉 첫 번째 열만 표시 할 수 있습니다. 세 개의 열을 모두 연결하여 텍스트 상자에 제안하는 방법.

내 코드 :

Dim strSql As String = "select P_Firstname, P_MiddleName, P_LastName from Patient_Registration" 
     Dim dtb As New DataTable 
     Using cnn As New SqlConnection(conn) 
      cnn.Open() 
      Using dad As New SqlDataAdapter(strSql, cnn) 
       dad.Fill(dtb) 
      End Using 
      cnn.Close() 
     End Using 
     txtsearch.AutoCompleteMode = AutoCompleteMode.SuggestAppend 
     txtsearch.AutoCompleteSource = AutoCompleteSource.CustomSource 
     If dtb.Rows.Count > 0 Then 
      Dim i As Integer = 0 
      For i = 0 To (dtb.Rows.Count - 1) 
       txtsearch.AutoCompleteCustomSource.Add(dtb.Rows(i)("P_FirstName")) 
      Next 
     End If 

Answer 1

사용 :

For i = 0 To (dtb.Rows.Count - 1) 
    txtsearch.AutoCompleteCustomSource.Add(dtb.Rows(i)("P_FirstName") & 
              dtb.Rows(i)("P_MiddleName") & 
              dtb.Rows(i)("P_LastName")) 
Next 

대신 :

For i = 0 To (dtb.Rows.Count - 1) 
    txtsearch.AutoCompleteCustomSource.Add(dtb.Rows(i)("P_FirstName")) 
Next
