How to retrieve the selected value from the Select tag in WinForms 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.
C#
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;
}
VB
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
