Solution 1

Without knowing what "b" is, I would say you need this:

VB

If RadioButton1.Checked = True Then
  b.Add(textBox27.Text)
Else
  b.Add("0")
End If

Solution 2

As you said:

Error converting data type nvarchar to int.

It seems that the "textbox27" do not contains a valid integer so it couldn't be parsed also "Else" block here is fixed to zero, so could you please try something like this:

VB

If RadioButton1.Checked = True Then
    b.Add(Val(textBox27.Text))
Else
    b.Add("0")
End If

Check out VAL functionality here.

I believe you have it backwards. It is the b.Add("0") that throws the error meaning b is a collection of integers.

Shahan Ayyub 3-Oct-12 14:41pm

If "b" is an integer collection than what if some one enter "some text here" in textbox27 and this line:

b.Add(textBox27.Text)

will definitely fail to add it to the collection with following error:
"Conversion from string "some text here" to type 'Integer' is not valid."

So my understanding is to have a use of VAL function, IF the end result is going to convert in SQL int datatype, since the error "Error converting data type nvarchar to int." seems to be a sql error.

You are correct. My bad.
