How to retrieve the selected value from the Select tag in HTMLUI?

Platform: WinForms |
Control: HTMLUIControl |
Published Date: April 30, 2011 |
Last Revised Date: July 10, 2014


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
