How do I access an HTML element at the point I am clicking on the HTMLUI control?

 

The htmluiControl.GetElementAtClientPoint() method gets the tag element that is present at the mentioned point.

The following code snippet shows tracing the clicked point from the MouseDown event and accessing the html element from the specified point.

C#

htmluiControl.MouseDown += new System.Windows.Forms.MouseEventHandler(this.htmluiControl_MouseDown);

private void htmluiControl_MouseDown(object sender, System.Windows.Forms.MouseEventArgs e)

{

 IHTMLElement element = htmluiControl.GetElementAtClientPoint(e.X, e.Y);

 if(element.Attributes.Contains("style") == false)

 {

  element.Attributes.Add("style");

 }

 element.Attributes["style"].Value = "background-color: blue;";

Console.WriteLine(element.Attributes["style"].Value.ToString());

}

VB

Private htmluiControl.MouseDown += New System.Windows.Forms.MouseEventHandler(Me.htmluiControl_MouseDown)

Private Sub htmluiControl_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs)

 Dim element As IHTMLElement = htmluiControl.GetElementAtClientPoint(e.X, e.Y)

 If element.Attributes.Contains("style") = False Then

  element.Attributes.Add("style")

 End If

 element.Attributes("style").Value = "background-color: blue;"

Console.WriteLine(element.Attributes("style").Value.ToString())

End Sub
