how to enable disabled linkbutton

I need to disable 4-5 linkbuttons when one of the linkbutton is clicked.My code works on both enabling and disabling  in Mozilla 18.0.1 and Chrome Version 24.0.1312.56  but in IE9 it disables but fails to enable with postback.How can i fix this.


protected void LinkButton1_Click(object sender, EventArgs e) { LinkButton.Enabled = false; LinkButton.Attributes.Add("disabled", "true"); } protected void LinkButton2_Click(object sender, EventArgs e) { LinkButton.Enabled = true; LinkButton.Attributes.Add("disabled", "false"); }
