How to toggle the visibility of an HTML element in WinForms HTMLUIControl at runtime?

Platform: WinForms |
Control: HTMLUIControl

Cell toggle

Each HTML element in the HTMLUI has an xVisible attribute by default that helps the user to toggle the visibility of a particular element. Since the xVisible is a bool property the value to be set is either true or false as string.

The following code snippet shows how an element's visibility is toggled on the execution of an event.


IHTMLElement image = Global.Document.GetElementByUserId("img");
image.Click += new EventHandler(image_Click);
IHTMLElement[] elem = this.htmluiControl1.Document.GetElementsByName("td");
public void image_Click(object sender, EventArgs e)
    string visibleString = "";
    if(this.bDescriptionHidden == false)
       visibleString = "false";
       visibleString = "true";
    this.bDescriptionHidden = !this.bDescriptionHidden;
    foreach (IHTMLElement description in elem)
       if(description.ID == "tdpopup")
          description.Attributes["xVisible"].Value = visibleString;



Private image As IHTMLElement = Global.Document.GetElementByUserId("img")
Private image.Click += New EventHandler(image_Click)
Private elem As IHTMLElement() = Me.htmluiControl1.Document.GetElementsByName("td")
Public Sub image_Click(ByVal sender As Object, ByVal e As EventArgs)
    Dim visibleString As String = ""
    If Me.bDescriptionHidden = False Then
       visibleString = "false"
       visibleString = "true"
    End If
    Me.bDescriptionHidden = Not Me.bDescriptionHidden
    For Each description As IHTMLElement In elem
       If description.ID = "tdpopup" Then
          description.Attributes("xVisible").Value = visibleString
       End If
    Next description
End Sub
