Hi All,

I am developing my own module and have done a few now but I have come across a situation where I want to show and hide data in the module, say a checkbox depending on the Security Group.

I have been using the following in the skin:

                        <%  If DotNetNuke.Security.PortalSecurity.IsInRole("Chasmont Staff")  Then %>

                        <% End If %>

Which works fine for skin files but causes exceptions in the module.

Is there some comparable code I can use in a module to do this?  I have done a lot of searching but have not been able to solve it.

Any help would be gratefully appreciated!

Thanks Mike

in your modules, you should evaluate visibility in code behind (depending on the model you are using)

Sebastian is right, you can handle the entire thing with code behind...

But if you still want to work with classic ASP in your module view .ascx file then you need to add a public property to the module's view code behind which will allow you to access it from the module's view.ascx in the same manner as you are doing with your skin's page.ascx.

I think the OP already plans to do this in the code behind file.

He wants to know what the equivalent code should look like. Can you help him?

Simple classic ASP with a code behind public property might look like this...

Somewhere in the Module Code Behind: view.ascx.cs

private bool _ShowPager = false; // typically you will set this value in your modules Page_Load event based on a module setting
public bool ShowPager
{
get { return _ShowPager; }
set { _ShowPager = value; }
}

Somewhere in the Module view.ascx Code:

<%if (ShowPager) {%>

<%}%>

One all code behind alternative would be to place a asp literal control on the module's view.ascx and populate it's Text property with markup by a function called from the Page_Load event whereby there would be no classic asp.net with the brackets on your view.ascx. You would however be then forced to build the UI HTML code via server side logic which can also get a little bit ugly. Really it's a case by case scenario in my book and if something is working and not a security or performance problem, that is probably the most important.

With a literal somewhere on the modules view.ascx such as:


When using a literal the modules view.ascx.cs Page_Load would look something like:

protected void Page_Load(object sender, EventArgs e)
{
.....
if(DotNetNuke.Security.PortalSecurity.IsInRole("Chasmont Staff") ){
ltlMyCode.Text = "
"; // You can apply all your necessary if logic here to drive your dynamic UI or abstract it into a separate function if it's DRYer
}
.....
}

Both achieve the same result and with Razor you could provide another version doing yet again... the same thing. A little HTML got stripped by the forum editor but it's close..
