Bulleted List Master Detail with DisplayMode=LinkButton (C#)

Hi,
I need to do the following: after calling a web service, the result of that call is a list. I need to display that list in a Master/Detail way using a bulleted list for the Master data and the LinkButton DisplayMode for the Detail data of each item.

With the code I currently have, I can display the Master data of the list with the Button1_click event handler, but I cannot display the details with the BulletedListMedicare_click.

when I use

LabelMedicare3.Text = supList.SupplierDatas[n].CompanyName

to access the data in the list, I get an error. This may have to do with the scope of the list, but I am new to C# so am lost.

Thanks in advance and regards.

Si_HibbardCommented:
In your function BulletedListMedicare_click you are referencing supList which does not exist.

In the other function you defined the object supList before accessing its data. So you may just need to add this reference, but without knowing what this class is, and its constructors etc its hard to say for sure.

-> medicare.SupplierDataList supList;

May just need to add that like to your second function, so you have a reference before calling -> supList.SupplierDatas[n].CompanyName;
