Programmatically set a custom module setting

Hi All,

I wrote some code to create a new DNN web page, set all my properties and then add one of my custom modules. However, I need to set a custom property of this module.

Here's a sample of the code that adds the module. Would the last line work to set the custom modules property called "CategoryID"?

Code:

ModuleInfo moduleInfo = new ModuleInfo();
moduleInfo.PortalID = 0;
moduleInfo.TabID = tabId;
moduleInfo.ModuleOrder = 1;
moduleInfo.ModuleTitle = "View Module";
moduleInfo.PaneName = "ContentPane";
moduleInfo.ModuleDefID = 235;
moduleInfo.InheritViewPermissions = true;
moduleInfo.AllTabs = false;
moduleInfo.Alignment = "Top";
moduleInfo.DisplayPrint = false;
moduleInfo.ModuleSettings["CategoryID"] = 3;

Thanks,
Mark

Re: Programmatically set a custom module setting

I'm closer to getting this but still could use some help.

My code can add the module. While it does not appear to change the setting, it does appear on the page. However, when I go to settings, I see the following error:

Error: is currently unavailable. DotNetNuke.Services.Exceptions.ModuleLoadException: Object reference not set to an instance of an object. ---> System.NullReferenceException: Object reference not set to an instance of an object. at DotNetNuke.Modules.Admin.Modules.ModuleSettingsPage.BindData() at DotNetNuke.Modules.Admin.Modules.ModuleSettingsPage.OnLoad(EventArgs e) --- End of inner exception stack trace ---

Does anyone know what's causing this?

Thanks,
Mark

Mark,

Do you save the setting? This can be done by something like

new ModuleController().UpdateModuleSetting(base.ModuleId, "CategoryID", "2");

Reading it should avoid to fire an exception as above, e.g. by

private int CategoryID()
{
    get
    {
       object o = base.Settings["CategoryID"];
       if (o == null) return -1; // or whatever default value
       return (int)o;
    }
    set { // Do the things above to save the value... }
}

Best wishes
Michael

Re: Programmatically set a custom module setting

Michael,

At this point I can add any module to a new page but the error occurs when I click "manage --> settings". Normally a pop-up window would appear and show the 4 tabs titled module settings, permissions, page settings and settings. It's here that I see the error. That's all that appears in the window.

Am I missing a step in adding the module to a page? The error mentions something about module settings and I wasn't sure if there's something that I'm missing while adding it to the page.

Thanks,
Mark
