to pass selectedvalue of multiple column combo box

[bhuvana]

Hi,

I have displayed combo box with 2 details -ID and Name.
where i have used

for dr in ds.tables(T1).rows
combobox1.add(dr(0).tostring+ "-" + dr(1).tostring)

the combo box displays with ID and Name.

when user clicks the specific value from combobox,oly the ID must be passed to another combo box,which inturn has another procedure to run

how can i pass ID value alone to any other button/combobox

thanks for the help in advance
