user's role.
i jus done with delete button as:
ImageButton deleteButton = (ImageButton)e.Row.Cells[3].Controls[2];
if (User.IsInRole("Tracker"))
{
deleteButton.Enabled = false;
deleteButton.ImageUrl = "../../images/Delete_Disabled.gif";
deleteButton.ToolTip = "Access is denied";
}

Seems like you have:
ShowButton("btnUpdate", (!isEditMode));
ShowButton("btnDelete", (!isEditMode));
ShowButton("btnSave", isEditMode);
ShowButton("btnCancel", isEditMode);
instead of!:
ShowButton("btnUpdateBlend", (!isEditMode));
ShowButton("btnDeleteBlend", (!isEditMode));
ShowButton("btnSaveBlend", isEditMode);
ShowButton("btnCancelBlend", isEditMode);
It happens....good luck.
