i think it will give
'Object reference not set to an instance of an object.' error.
because when u click on link button and press yes in your confirmation msg it will go to row data bound when it finds the button and check condition
if (lblGrdStatus.Text != "Translation")
{
lnkDelete.Enabled = false;
}
but have no text so will result in error.

In asp:linkbutton if it is disable then it wil apply this

HTML

class="aspNetDisabled"

. so you just need to check on that javascript click function that clicked source is have this class attach or not?. this will solve your problem.

Add below code with your code at code behind hope it will work

C#

LinkButton lnkDelete = (LinkButton)e.Row.FindControl("lnkDelete");
if (lblGrdStatus.Text != "Waiting")
{
lnkDelete.Enabled = false;
LinkButton1.OnClientClick = "return false;";
}
