  ServerControl Inner property

  Mar 16, 2012 06:14 PM|LINK

  I am writing a server control that is to replace the ASP.NET SQLDataSource. I want it to have an innerproperty that can be set to diffent inherited types. Is this possible or do I need to pass the ID of the dependent control and declare it outside of my control? Here is what I want it to act like:

  <sb:SBObjectDataSource runat="Server" ID="SBObjectDataSource1" ConnectionString="..."
          SelectCommand="SELECT * FROM Contacts;">
          <CacheManager>
              <sb:SBCacheManager runat="server"/>
          </CacheManager>
   </sb:SBObjectDataSource>

  My goal is to create diffrent cache managers and have them inherit from one type so that I can have different kinds of caching like Session etc....

  Hear is the property:

          [Browsable(false)]
          [DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)]
          [PersistenceMode(PersistenceMode.InnerProperty)]
          public SBCacheManager CacheManager
          {
              get;
              set;
          }

  This does not work:

  What do you mean by that？if a property can be set to different kinds of inherited types……which "inherited types" do you want？And you should find a common father class for them……

  Yeah. I know how to create a base class. My question is how do I support this in markup.

  Please change to this：

  [DesignerSerializationVisibility(DesignerSerializationVisibility.Content)]

  That helped but now I can set properties on it but it doesnt allow me to decalre diffrent instances.

  I can do the following:

  <sb:SBObjectDataSource runat="Server" ID="ods" ConnectionString="Data Source=HOU-SQLDEV03;Integrated Security=True"
          SelectCommand="SELECT * FROM Contacts; SELECT * FROM Issues;">
          <CacheManager />
      </sb:SBObjectDataSource>

  But I want to be able to do the above and set the property to an instance of an object that is inherited from a base class.

  Well……You've been back to what I said above……Make sure that all of your classes MUST inherit from a base one。

  And I cannot understand what you really want？Show us your expected codes ：）

  <sb:SBObjectDataSource runat="Server" ID="SBObjectDataSource1" ConnectionString="..."
          SelectCommand="SELECT * FROM Contacts;">
          <CacheManager>
              <sb:SBCacheManager runat="server"/>
          </CacheManager>
   </sb:SBObjectDataSource>

  I want it to behave like inner control collections but I dont need a collection I just need a single item for the property. The above code is what I am going for but it does not work.

  The reason I am doing it is I want to be able to plug in diffrent SBCacheManager objects that may behave diffrently.

  I get the folloing error:

  SBCacheManager' does not have a public property named 'SBCacheManager'.

  I assume this means it is looking for a property of CacheManager. I am trying to assign it an instance. Just like I would do this in code behind:

  ods.CacheManager = new SBCacheManager();
