Thanks @louisfr and @David Johnson, CD, MVP. I'm trying to get it to work now. I will report back shortly.

Hello @David Johnson, CD, MVP I tried this. But when I do this it resets it to false every time I click on another page element b'c I have autopostback set to true in order for my radiobuttonlists to work.
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Panel1.Visible = False
End Sub

So instead I had to put all my panels in an if statement to check if it's visible each time the page does a postback

Hello @louisfr. I also tried doing what you said. At the beginning of the file in the page load I check to see if Other is a selected value but I don't this that works unless the user click Other first. Here is that code:

If (cblEduAssistPlans.SelectedValue = "Other") Then
            pnlEduAssistPlans.Visible = True
        Else
            pnlEduAssistPlans.Visible = False
        End If

        If (cblEduAssistPlans.SelectedValue = "") Then
            pnlEduAssistPlans.Visible = False
        End If

Then I tried to do what you said and iterate through the list to get the values that have been selected. Here is that code:

For Each li As ListItem In cblEduAssistPlans.Items
            If li.Selected = True Then Response.Write("cblEduAssistPlans2 " & li.Value & "<br>")
            If li.Value = "Other" Then pnlEduAssistPlans.Visible = True Else pnlEduAssistPlans.Visible = False

        Next
        Response.Write("<br>pnlEduAssistPlans: " & pnlEduAssistPlans.Visible)

Also. Each time the user makes a choice I want to check to see if they chose other so I can make the panel with the textbox appear. Here is the code I used for that.

Protected Sub cblEduAssistPlans_SelectedIndexChanged(sender As Object, e As EventArgs)
        If (cblEduAssistPlans.SelectedValue = "Other") Then
            pnlEduAssistPlans.Visible = True
        End If
    End Sub

This is my checkbox list:

<asp:CheckBoxList ID="cblEduAssistPlans" runat="server" SelectedIndexChanged="cblEduAssistPlans_SelectedIndexChanged" AutoPostBack="true">
                       <asp:ListItem>Individualized education program (IEP)</asp:ListItem>
                       <asp:ListItem>Individualized Family Service Plan (IFSP)</asp:ListItem>
                       <asp:ListItem>504 Plan</asp:ListItem>
                       <asp:ListItem>Other</asp:ListItem>
                   </asp:CheckBoxList>

This is my panel:

<asp:Panel ID="pnlEduAssistPlans" runat="server">
           <table style="width:100%;">
               <tr>
                   <td>Enter assistance plan <asp:TextBox ID="txtEduAssistPlans" runat="server"></asp:TextBox></td>
               </tr>
           </table>
       </asp:Panel>

I don't know why this isn't working. The visible value for pnlEduAssistPlans panel is always True.

Hello @louisfr. I'm sorry. No. I didn't try the panel code you provided. I wasn't sure how to implement it. However I do understand the explanation you left above. I will try this now and let you know if I'm able to get it working. Thank you.

The one-line code checks if any item is selected and has the text "Other". It returns True if any item matches the condition, False otherwise.
Except for the Response.Write statements, it does the same thing as the loop.

Thanks @louisfr. That worked!!!!! That makes perfect sense now that you explained it. Thanks a lot.
