Error:

DotNetNuke.Services.Exceptions.ModuleLoadException: The type initializer for 'MyModule.DataProvider' threw an exception. ---> System.TypeInitializationException: The type initializer for 'MyModule.DataProvider' threw an exception. --->

Answer:

This is caused by upgrading your module from DNN3 to DNN4. In your dataprovider, Change:

CType(Framework.Reflection.CreateObject("data", "MyModule", "MyModule.dll"), DataProvider)

To:

CType(Framework.Reflection.CreateObject("data", "MyModule", ""), DataProvider)

 Error:

The module works fine when logged in as an administrator, but when a normal user uses it they do not get the post back click event or the page doesn't refresh.

Answer:

The module has caching enabled. Set the caching to 0 and click the update link in the module configuration settings for the module.

Failed to generate a user instance of SQL Server due to a failure in starting the process for the user instance. The connection will be closed.

Answer:

Caused when using SQL Server express. In the web.config, change:

 <add name="SiteSqlServer" connectionString="Data Source=.\SQLExpress;AttachDbFilename=|DataDirectory|Database.mdf;Integrated Security=True;User Instance=True" providerName="System.Data.SqlClient" />

to:

 <add name="SiteSqlServer" connectionString="Data Source=.\SQLExpress;AttachDbFilename=|DataDirectory|Database.mdf;Integrated Security=True;User Instance=False" providerName="System.Data.SqlClient" />
   

 

Error:

Exception has been thrown by the target of an invocation ... 

Answer:

If you have code that calls the database, ensure that a value is being returned fron the databse. Otherwise you will get this error.

Error:

The PopupControlExtender places the popup in the wrong place when the page is scrolled

Answer:

 

 

When the page scrolls, the popup control will lose position unless you place the items in a panel and give it a CssClass class like:

 

 

< asp:Panel ID="pnlUsers" runat="server" Height="50px" Width="125px" CssClass="PanelExtender" >

Then you give that .css class a  position of relative like:

< style >
.PanelExtender
{
    position: relative;
}
< /style >
