I think you can use this code for binding your CheckBoxList2 to DataTable as follow.

CheckBoxList2.DataSource = ds.Tables[0];
CheckBoxList2.DataTextField = "subj_nme";
CheckBoxList2.DataValueField = "subjid";
CheckBoxList2.DataBind();
CheckBoxList2.Font.Name = "Verdana";
CheckBoxList2.Font.Size = 12;

To check them all you can do this

for(int i=0;i<CheckBoxList2.Items.Count;i++)
{
CheckBoxList2.Items[i].Selected = true;
}
