enable / dosable RadCombobox

[Sofiene]

hi ,
I have a RadComboBox in my RadGrid Edit Form , when item created i catch the element asked in question ans his RequereFieldValidator  clientId .  In a JavaScript function i like to manipulate this too edit form control but that not worked : manipulate disabled / enabled property not disable / enable my control in form .


my C# code :

var radMotif = (RadComboBox)editFormItem.FindControl("IdMotifRejet");
var requiredradMotif = editFormItem.FindControl("RequiredFieldValidatorMotifRejet");

GridPJ.Controls.Add(new LiteralControl("<script type='text/javascript'>window['IdMotifRejet'] = '" + radMotif.ClientID + "';</script>"));
GridPJ.Controls.Add(new LiteralControl("<script type='text/javascript'>window['RequiredFieldValidatorMotifRejet'] = '" + requiredradMotif.ClientID + "';</script>"));

my Javascript Function

var cIdMotifRejet = document.getElementById(window['IdMotifRejet']);
cIdMotifRejet.disabled = false;
document.getElementById(window['RequiredFieldValidatorMotifRejet']).disabled = false;

document.getElementById get the control but without all of his property/methods , must use

var cIdMotifRejet = $find(window['IdMotifRejet']);
 cIdMotifRejet.disable();
