Programmatically selected a TButtonItem in a TCategoryButton.

Thanks to Experts Exchange, I have learned how to dyamically load a TCategoryButtons component
with categories and button items and display them on demand. Here is my logic:

(This information is in my header file!)
//button category
TButtonCategory **bcCategory;
//button items
TButtonItem **biAssignment;

iassignindex = 0;
for (icatindex = 0; icatindex < MainWindow->itotalcategories; icatindex++)
{
     //----------------------------------------------------------------
     //  add a category button...
     //----------------------------------------------------------------
     bcCategory[icatindex] = cbCatsAndAssignsPad->Categories->Add();

     //----------------------------------------------------------------
     //  load the category caption...
     //----------------------------------------------------------------
    bcCategory[icatindex]->Caption = MainWindow->category[icatindex].name;

     for (icount = 0; icount < MainWindow->category[icatindex].numberofassignments; icount++)
           {
      //----------------------------------------------------------------
      //  add an assignment button...
      //----------------------------------------------------------------
      biAssignment[icount] = bcCategory[icatindex]->Items->Add();

      //----------------------------------------------------------------
      //  load the assignment caption...
      //----------------------------------------------------------------
      biAssignment[icount]->Caption = MainWindow->assignment[iassignindex].name;

      iassignindex = iassignindex + 1;
          }
}

What I need to know is how do I programatically select a particular button item IN A CATEGORY
when the component is displayed?

The documentation is of no help!

Thanks!!

Better late than never...
I'm not currently work with bcb2006 but this is a general idea.
Since TButtonItem is descend from TButton then you can assign a value in the Tag property...
Also for all buttons you can assign a global OnMouseClick in example derived method to be processed when you are clicking any of these buttons...
Detecting the value of Tag property you can find out the button pressed.
I hope this is what you wanted.

Another approach is to use some TButtonItem property to do that.
As I have only BCB6 Personal, I don't have these components, but probably the Object Inspector in BCB Developer Studio 2006 shows Properties as the one you are looking for. Something similar to the ToolBar with two ToolButtons, where the ToolButton->Images Property has an index related to an ImageList with two bitmaps and such indexes can be modified programaticatly, as in:
void __fastcall TForm1::Button1Click(TObject *Sender)
{
    if (ToolButton2->ImageIndex==2)
    {
        ToolButton2->ImageIndex=1;
        ToolButton1->ImageIndex=2;
    }
    else
    {
        ToolButton1->ImageIndex=1;
        ToolButton2->ImageIndex=2;
    }
}
