C#-APP: Problems dynamically databinding comboboxes

[theleshie]

Hi,
I am creating an application which dynamically creates forms depending on the information held in a dataset (which also includes the data the application itself uses). As part of dynamically creating these forms, I need to bind controls back to their underlying tables. This has been successful with textboxes, but I am having a lot of difficulty with comboboxes. Setting the datasource to the bindinglist seems to be ok, but I am having trouble setting the selectedindex/item/value (I believe it is item I need to use to bind to the underlying object) when I initialise the form, FindStringExact doesn't seem to be able to find the item which throws an exception.

Here is the part of the code which generates comboboxes:

//datarowview for the particular piece of information
DataRowView drv_dataRow = ((DynamicCharac teristic)cashfl owchars[i]).getDataRow();
//instantiate new combobox
ComboBox cboBox_char = new ComboBox();
//set name
cboBox_char.Nam e = ((DynamicCharac teristic)cashfl owchars[i]).getCharID().T oString();
//get options for combobox
ArrayList options = ((DynamicCharac teristic)cashfl owchars[i]).getOptions();

//create bindinglist from array
BindingList<PDR eportDataSet.Ch aracteristicLis tItemRow> bl = new BindingList<PDR eportDataSet.Ch aracteristicLis tItemRow>();

//populte bindinglist
for (int j = 0; j < options.Count; j++)
{
bl.Add((PDRepor tDataSet.Charac teristicListIte mRow)options[j]);
}

//set members and datasource
cboBox_char.Dis playMember = "ShortName" ;
cboBox_char.Val ueMember = "Characteristic ListItemID";
cboBox_char.Dat aSource = bl;

//set databinding
cboBox_char.Dat aBindings.Add(" SelectedValue", drv_dataRow, "Characteristic Value");

//set current item in combobox
int index = cboBox_char.Fin dStringExact(xm lRenderingClass .getListItemNam e(Int32.Parse(( (DynamicCharact eristic)cashflo wchars[i]).getVal())));
cboBox_char.Sel ectedIndex = index;
//add event handling
cboBox_char.Sel ectedIndexChang ed += new System.EventHan dler(this.chara cteristicComboB ox_SelectedInde xChanged);
//format combobox
cboBox_char.Dro pDownStyle = ComboBoxStyle.D ropDownList;
cboBox_char.Wid th = 200;
//add control to tablelayoutpane l
tablepanel.Cont rols.Add(cboBox _char, 1, i);


Any help would be much appreciated!
