If a new DataRow is added to the DataTable during runtime, then how can I trigger the update?

Platform: WinForms |
Control: AutoComplete |

You need to call this.autoComplete1.SetTableData() method which sets the internal table data based on the AutoComplete control's DataSource property.


DataTable dt;

private void Form1_Load(object sender, System.EventArgs e)


dt=new DataTable("select");



dt.Rows.Add(new object[]{"NorthCarolina" });

dt.Rows.Add(new object[]{"India " });

dt.Rows.Add(new object[]{"New York " });

dt.Rows.Add(new object[]{"Washington " });

dt.Rows.Add(new object[]{"London"});

dt.Rows.Add(new object[]{"Canada"});



private void button1_Click(object sender, System.EventArgs e)


dt.Rows.Add(new object[]{"new1"});

dt.Rows.Add(new object[]{"new2"});

//sets the internal table data based on the AutoComplete.DataSource property.

this.autoComplete1.SetTableData ();



Private dt As DataTable

Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs)

dt = New DataTable("select")



dt.Rows.Add(New Object() {"NorthCarolina"})

dt.Rows.Add(New Object() {"India "})

dt.Rows.Add(New Object() {"New York "})

dt.Rows.Add(New Object() {"Washington "})

dt.Rows.Add(New Object() {"London"})

dt.Rows.Add(New Object() {"Canada"})

autoComplete1.DataSource = dt

End Sub

Private Sub button1_Click(ByVal sender As Object, ByVal e As System.EventArgs)

dt.Rows.Add(New Object() {"new1"})

dt.Rows.Add(New Object() {"new2"})


End Sub
