How to add an attribute to an HTML element and change its value at runtime in WinForms HTMLUIControl?
HTML element
The attributes to the HTML elements can be added using the Add method of the Attributes property, as shown in the code snippet below.
C#
// textBox is an INPUT element of type 'text' in the HTML document
if(this.textBox.Attributes.Contains("style") == false)
this.textBox.Attributes.Add("style");
VB
' textBox is an INPUT element of type 'text' in the HTML document
If Me.textBox.Attributes.Contains("style") = False Then
Me.textBox.Attributes.Add("style")
End If
The element's attribute can be changed at run time by assigning a suitable value to the Value property of that particular attribute, as shown in the code snippet below.
C#
// textBox is an INPUT element of type 'text' in the HTML document this.textBox.Attributes["style"].Value = "background-color:red";
VB
' textBox is an INPUT element of type 'text' in the HTML document
Private Me.textBox.Attributes("style").Value = "background-color:red"
