How to retrieve the selected value from the Select tag in WinForms HTMLUIControl?

Platform: WinForms |
Control: HTMLUIControl

Select tag in HTMLUI

We can retrieve the selected value from the Select tag by retrieving the SelectedItem property of the SELECTElementImpl''s embedded CustomControl.


private void button1_Click(object sender, EventArgs e)
     SELECTElementImpl htmlElement = (SELECTElementImpl)this.htmluiControl1.Document.GetElementByUserId("Select1");
     ListBox list = htmlElement.UserControl.CustomControl as ListBox;
     this.textBox1.Text = (string)list.SelectedItem;



Private Sub button1_Click(ByVal sender As Object, ByVal e As EventArgs) Handles button1.Click
     Dim htmlElement As SELECTElementImpl = CType(Me.htmluiControl1.Document.GetElementByUserId("Select1"), SELECTElementImpl)
     Dim list As ListBox = TryCast(htmlElement.UserControl.CustomControl, ListBox)
     Me.textBox1.Text = CStr(list.SelectedItem)
End Sub
