Show HyperLink when ASP.Net CheckBox is checked using C# and VB.Net

Hi SUJAYS,

You need to set Visible or Enable Propery True OnCheckedChanged event and AutoPostBack="true".

Please refer below sample.

HTML

<table>
    <tr>
        <td>
            <asp:CheckBox ID="chkName" runat="server" OnCheckedChanged="Show" AutoPostBack="true" />
        </td>
        <td>
            <asp:HyperLink ID="lnkName" runat="server" NavigateUrl="#" Text="ASPSnippets" Visible="false"></asp:HyperLink>
        </td>
    </tr>
</table>

Code

C#

protected void Show(object sender, EventArgs e)
{
    if (chkName.Checked == true)
    {
        lnkName.Visible = true;
    }
    else
    {
        lnkName.Visible = false;
    }

}

VB.Net

Protected Sub Show(ByVal sender As Object, ByVal e As EventArgs)
    If chkName.Checked = True Then
        lnkName.Visible = True
    Else
        lnkName.Visible = False
    End If
End Sub
