I have a dictionary that is populated with data from a table, we are doing this so we can hold multiple SQL tables inside this object. This approached cannot be discussed.

The Dictionary is mapped as a , and contains SQL column name and the value, and each dictionary resembles one row entry in the Table.

Now I need to display this on a editable gridview, preferably the ASPxGridView. I already figured out that I should use Dynamic Objects(C#), and everything worked perfectly, up to the part where I find out that the ASPxGridview is built in .NET 2.0 and not 4.0 where Dynamic objects where implemented, therefor I cannot use it... As you cannot, to my knowledge, add rows to the gridview programmatically, I am out of ideas, and seek your help guys!

    protected void Page_Load(object sender, EventArgs e)
    {
        UserValidationTableDataProvider uvtDataprovider = _DALFactory.getProvider<UserValidationTableDataProvider>(typeof(UserValidationTableEntry));
        string[] tableNames = uvtDataprovider.TableNames;
        UserValidationTableEntry[] entries = uvtDataprovider.getAllrecordsFromTable(tableNames[0]);

        userValidtionTableGridView.Columns.Clear();
        Dictionary<string, string> firstEntry = entries[0].Values;
        foreach (KeyValuePair<string, string> kvp in firstEntry)
        {
            userValidtionTableGridView.Columns.Add(new GridViewDataColumn(kvp.Key));
        }
        var dynamicObjectList = new List<dynamic>();
        foreach (UserValidationTableEntry uvt in entries)
        {
            //dynamic dynObject = new MyDynamicObject(uvt.Values);
            dynamicObjectList.Add(new MyDynamicObject(uvt.Values));
        }
    }

    public class MyDynamicObject : DynamicObject
    {
        Dictionary<string, string> properties = new Dictionary<string, string>();

        public MyDynamicObject(Dictionary<string, string> dictio)
        {
            properties = dictio;
        }

        // If you try to get a value of a property 
        // not defined in the class, this method is called.
        public override bool TryGetMember(GetMemberBinder binder, out object result)
        {
            // Converting the property name to lowercase
            // so that property names become case-insensitive.
            string name = binder.Name.ToLower();
            string RResult;
            // If the property name is found in a dictionary,
            // set the result parameter to the property value and return true.
            // Otherwise, return false.
            bool wasSuccesfull = properties.TryGetValue(name, out RResult);
            result = RResult;
            return wasSuccesfull;
        }

        // If you try to set a value of a property that is
        // not defined in the class, this method is called.
        public override bool TrySetMember(SetMemberBinder binder, object value)
        {
            // Converting the property name to lowercase
            // so that property names become case-insensitive.
            properties[binder.Name.ToLower()] = value.ToString();

            // You can always add a value to a dictionary,
            // so this method always returns true.
            return true;
        }
    }

Now, I am almost certain that his "Dynamic object" approach, is not the one I can go with from here on.

I hope you guys can help me :)!
