  Hi, I have seen a few posts around this topic, and have already read this
  
  http://sitefinitywatch.com/blog/09-03-10/Using_Enumerators_to_Auto-generate_a_Dropdown.aspx
  
  but this isnt what I want. Gabes example is a simple list of colours.  I need a drop down list that is furnished from the database, so enums are not appropriate (i dont think anyway) because I need a drop down list with a string text and a guid value, and to expose the guid value that the user chooses, for me to do some database logic in what to show in the view, which is my custom control. I am aware you have more flexibility with control designers and web editors for customising the properties section, but I really dont have time to delve into this right now, it looks quite involved. I just need a simple drop down box showing a list of things.
  
  Any ideas? Can I use enums in this way?
  
  Thanks, Louise.

  Hello LouiseBA,
  
  You need to use Control Designers or WebUI TypeEditor. The properties section of the Designer wokrs only with enum, TextBox ( it is automatically generated) and boolean type properties ( true false DropDown is automatically generated).

  I looked at the code and I'm glad to say that it worked generally well in practice/tests.  However, being that the properties in the designer only supports enums, how can you make a drop down list to pull from dynamic content.
  
  The long story short is that I created a new Gallery module and when I embed the control in one of the pages, I need to be able to select from one of the many galleries that were defined in the module.  Enum wouldn't work because the end-user may add or remove from the available galleries and those changes need to be reflected in the drop down list.
  
  What do you suggest?
  
  Thanks,

  Hi Frank Nieto,

  You can do this in the ControlDesigner and its template. You could expose a property in the control designer and the control. The selected value of the DropDown in the Control Designer will be set as a property of the control.
  
  sample code
  
  ControlDesigner
  
  

  protected override void CreateChildControls()

     {

         base.CreateChildControls();

   

         if (combo != null)

         {

          // here you can populate the RadComboBox - bind it to your data Source

    

         }

          // when you open the designer set the value of the Index property to the

          // RadComboBox control in the Designer

         combo.SelectedValue = ((CustomImageControl)DesignedControl).Index;

     }

   

   

   

   

     public override void OnSaving()

     {

   

         base.OnSaving();

       // set the Index property of your custom control to the Selected value of

       // the RadCombobox control

       ((CustomImageControl)DesignedControl).Index = combo.SelectedValue;  

     }

   

   

     public RadComboBox combo

     {

         get

         {

             return base.Container.GetControl<RadComboBox>("RadComboBox1", true);

         }

     }

  
  property in the CustomImageControl
  
  

  public string Index

      {

          get

          {

              object obj = this.ViewState["Index"];

              if (obj != null)

                  return (string)obj;

              return "";

   

          }

          set

          {

              this.ViewState["Index"] = value;

          }

      }

  Hello,
  
  Telerik.Framewrok.dll should be in your bin folder. You need to use Control Designers or WebUI TypeEditor.
