DropDown type of property for server component.8/16/2004 11:11:10 PM

0/0

I am building server control to be added to ViSual Studio tollbox. I want one of the properties to be like a DropDown type. So when developer has to set this property he will simply select one of the options from dropdown, but I can't use enumerations because data for dropdown comes from the database.

If anyone has an idea how to do this please advice.

I can tell you how to create a dropdownlist for a string property, but how do you plan on knowing/setting the database connection string at design time?

That's easy I will simply have another propert let's say Connection which will be up to user to set it first.

By reading the connection string out of the web.config after doing a bunch of crufty stuff with EnvDTE to find the file.

Andrew,

I still didn't get the first part. When I read connection string property retrieve the data and populate this other property it works fine if the property of type ArrayList or array of strings but when I try to make the property of type DropDownList it is not being populated.

Please advice.

Regards,
Dimitry

you can use code similar to this to make your string property have a dropdownlist UI in the propertygrid. Just change it to get your data instead of getting a list of server controls.

Andy, Thanks for directions.



Does anyone know if there is a way to a pass back parameters to TypeConverter class or set its properties or maybe let's say use it dynamically not like this bellow: 



<TypeConverter(GetType(StatesList)), _


    CategoryAttribute("Custom List"), DefaultValueAttribute(""), _


    DescriptionAttribute("Select a state from the list")> _


    Public Property State() As String


        Get


            Return _State


        End Get


        Set(ByVal Value As String)


            _State = Value


        End Set


    End Property
