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"
