You can use LDAP with DirectorySearcher to find a particular user in AD. You have a lot of articles Link 1[^], Link 2[^], Link 3[^]

I've just started dabbling in ASP.NET properly and might be missing something obvious here, in this snippet of code:

<asp:Panel ID="panRepresentatives" runat="server" Visible="<%#this.GetDefaultVisible() %>">
    <h1>Executive Committee Discipline Representatives</h1>
    <asp:Repeater ID="repRepresentatives" runat="server" DataSourceID="dsRepresentatives">
        <HeaderTemplate>...</HeaderTemplate>
        <ItemTemplate>...</ItemTemplate>
        <FooterTemplate>...</FooterTemplate>
    </asp:Repeater>
</asp:Panel>

What should happen is the panel should not be rendered when there are certain query strings passed to the page. GetDefaultVisible is implemented as such:

protected bool GetDefaultVisible()
{
    if ((this.Request.QueryString["position"] == null) && (this.Request.QueryString["id"] == null))
        return true;
    return false;
}

Now above this in the page is another asp:Panel which is always displayed, but inside that is another asp:Repeater control and the visiblity of this is controlled by another method which matches the database Position against the position passed in the query string or the database Id against the query string id. If they match then that particular panel is displayed, otherwise it's hidden.

The hiding / showing of panels is working fine in the code above this snippet but for the provided snippet the call to GetDefaultVisible is not happening at all Unsure | :~

, by stepping through the code I've verified that GetDefaultVisible is not called from the Visible="..." section of panRepresentatives.

Can anybody see what is wrong? I can provide more code if required but it's tied up in database connectivity and it's not really relevant to the discussion.

Is there a reason you wouldn't want to do this in the Page_Load event?

protected void Page_Load(object sender, EventArgs e)
{
  if ((this.Request.QueryString["position"] == null) && (this.Request.QueryString["id"] == null))
      panRepresentatives.Visible = false;
  else
      panRepresentatives.Visible = true;
}

I could, perhaps it's just a personal preference but the GetDefaultVisible is actually used by another part of the page (the omitted) part. But I'll try putting a call to it in there and see if anything changes. If it does all well and good but it still doesn't get away from the fact that it should be getting called, even if there is a better way of writing the page Roll eyes | :rolleyes:

You could still do

panRepresentatives.Visible = GetDefaultVisible();

I think the problem is with the Page life cycle of an Asp.Net page. I probably need to sit and think what happens in the page life cycle for the panel. I just had my lunch and really lazy Roll eyes | :rolleyes:

to do it

That's what I just did, anyway thanks for the help, but I've decided I've approached things the wrong way (generally, in terms of planning for the future). So I'm going to have a sit down and a doodle while watching House and design it properly Roll eyes | :rolleyes:

Ed.Poore2-Aug-07 9:52

[update]That does work as expected[/update]

I'll use that method for now, but it still doesn't explain why the method isn't called, oddly enough if you copy the Visible="<%#this.GetDefaultVisible() %>" attribute through all the children of the panel then the panel is hidden, but that kind of defeats the purpose of it.

if s = your string returned fromt he database, you'd use

s.replace(vbCrLf, "<br />")

in VB - you'll have to look up the C++ or C# versions yourself if you need them... but the VB constant vbCrLf is just the carriage-return line-feed characters which are Chr(13) and Chr(10), so you can maybe work this out yourself... ie, the VB equivalkent is

s.replace(Chr(13) & Chr(10), "<br />")

(it's probably the same in C except for the ; at the end)
