Hi,

This should be fairly simple, but it is driving me nuts. First off I have a
table in SQL Server, with a column of type "bit". This is meant to store a
answer to a Yes/No question.

I'm trying to display this stored value in SQL Server in a RadioButtonList
in ASP.NET. I have the value stored in ado.net DataSet, which I can
reference just like this
myDataSet.Tables(0).Rows(0)("my_bit_column")

My problem is, I don't know how to bind this result, to the RadioButtonList.
I would believe I need to use the RadioButtonList's methods FindByText or
FindByValue methods, and I've tried something like this...

RadioButtonList1.Items.FindByValue(CStr(myDataSet.Tables(0).Rows(0)("my_bit_
column"))).Selected = True

But I get this beautiful error.."System.NullReferenceException: Object
reference not set to an instance of an object."

Can anyone help me out, it seems I'm making this more complicated that it
has to be!

Thanks!

Apparently it can't find that value in the FindByValue. Are you sure
you do a DataBind before trying to do this line? Otherwise your items
in the list aren't created yet....
