How do I access Checkbox list variables using VB in Visual Studio?

Question

How do I retrieve values from the Check box list control in visual studio using visual basic? Currently I'm using "Reason.Text", but I need to retrieve all the variables that are checked.

Answer 1

Take a look at this simple sample :

Here the button code :

 Protected Sub btnGetValues_Click(sender As Object, e As EventArgs) Handles btnGetValues.Click

    Dim Sb As New System.Text.StringBuilder


    'to get al values using linq reaons.items as Listitem which expose selected property and you may filter on this
    'property too as per my example
    Dim X = (From a As ListItem In reason.Items Where a.Selected = True Select a.Value).ToList
    For Each el In X
        Sb.Append(el.ToString & "<br/>")
    Next
    lit1.Text = Sb.ToString
    Sb.Clear()


    'to get anonymous type with multiples params you may use this:
    Dim k = (From a As ListItem In reason.Items Where a.Selected = True Select New With {.Checked = a.Selected, .TextValue = a.Text, .IDValue = a.Value}).ToList

    For Each el In k
        Sb.Append(String.Format("IsSelected=<b>{0}</b>, TextNameValue=<b>{1}</b>, IntegerValue=<b>{2}</b><br/>", el.Checked, el.TextValue, el.IDValue))
    Next
    lit2.Text = Sb.ToString
    Sb.Clear()
    Sb = Nothing


End Sub
