Randomly load CheckBoxList item in ASP.Net

Hi kelsen1989,

Please refer below sample.

HTML

<p>
    4. If stuck by a needle, one should:
    <asp:CustomValidator ID="CustomValidator4" ErrorMessage="*" ForeColor="Red" ClientValidationFunction="ValidatechkQ4"
        runat="server" />
    <asp:CheckBoxList ID="ChkQ4" runat="server" AutoPostBack="True">
        <asp:ListItem Value="a">Rinse the site with water and not tell anyone</asp:ListItem>
        <asp:ListItem Value="b">Wash site with soap and water and immediately report the incident to the facility supervisor</asp:ListItem>
        <asp:ListItem Value="c">Squeeze the needle stick area until the site bleeds</asp:ListItem>
        <asp:ListItem Value="d">Go directly to the facility lab to have laboratory tests completed</asp:ListItem>
    </asp:CheckBoxList>
</p>

Code

C#

protected void Page_Load(object sender, EventArgs e)
{
    List<ListItem> checkBoxItems = new List<ListItem>();
    foreach (ListItem item in ChkQ4.Items)
    {
        checkBoxItems.Add(item);
    }
    ChkQ4.Items.Clear();
    ChkQ4.DataSource = checkBoxItems.OrderBy(x => Guid.NewGuid()).ToList();
    ChkQ4.DataBind();
}

VB.Net

Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs) Handles Me.Load
    Dim checkBoxItems As List(Of ListItem) = New List(Of ListItem)()
    For Each item As ListItem In ChkQ4.Items
        checkBoxItems.Add(item)
    Next
    ChkQ4.Items.Clear()
    ChkQ4.DataSource = checkBoxItems.OrderBy(Function(x) Guid.NewGuid()).ToList()
    ChkQ4.DataBind()
End Sub

Thank you! But I have set the AutoPostBack="True" for the checkboxlist. When I click on the checkboxlist it automatically shift the items. Is there a way to fix that? 

 Please on Page_Load use below code

if (!this.IsPostBack)
{
// code
}
