listbox is not enabled using the below conditon

Question

In my operation i want to edit an employee list. In this time am using the below statement to disable listbox.

  this.lstbox.Attributes.Add("Disabled", ""); 

After the updation am using the below code to enable list box .

  this.lstbox.Attributes.Add("enabled", "");

First condition is working properly but second one does not return any error and list box not enabled..

Please help me to fix this..

Answer 1

without ever touching asp.net but after looking at: "list box enabled example"

can't you just write:

lstbox.Enabled = true;
lstbox.Enabled = false;

Answer 2

I think you should rather remove the "Disabled" attribute:

lstbox.Attributes.Remove("Disabled");
