How can I add an attribute to an HTML element and change its value at runtime?

Platform: WinForms |
Control: HTMLUIControl |

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"
