Question

First of all, the only post (calling-multiple-dopostback-from-javascript) I found about this didn\'t help my problem, so I don\'t belive this post is a duplicate.

You could pass the two values as one JSON string:

function OpenSubTable(bolID, controlID) {
  __doPostBack('UpdatePanelSearch', JSON.stringify({ bolID: bolID, controlID: controlID}));
}

And then parse it on the server:

protected void UpdatePanelSearch_Load(object sender, EventArgs e)
{
  SomeDTO deserializedArgs = 
      JsonConvert.DeserializeObject(Request["__EVENTARGUMENT"]);
  var bolID = deserializedArgs.bolID;
  var controlID = deserializedArgs.controlID;
}

public class SomeDTO
{
    public string bolID { get; set; }
    public string controlID { get; set; }
}

If you're using .Net >=4.0, I believe you can deserialize to a generic touple and avoid having to create SomeDTO. Edit: More information about deserializing to dynamic types.
