Not clear. What do you mean by 'enable' or disable control here?

Edit and rephrase it.

Solution 1

use combobox selectedindexchanged event as set AutoPostback=true
on basis of recieved selected index
u can enable or disable textboxes like

if(combo1.selecteditem.text=="a")
txtbox1.enabled=true;
else
txtbox1.enabled=false;

Solution 2

Use the SelectedIndexChanged event of the combo box. In that method, you can use

TextBox.Enable = true; // to enable it

TextBox.Enable = false;  // to disable it

Solution 3

If you mean to disable textboxes while selection process is active you should check out:

C#

private void comboBox1_DropDown(object sender, EventArgs e)
{
    //Do your stuff
}
private void comboBox1_DropDownClosed(object sender, EventArgs e)
{
    //Undo your stuff
}
