Custom Server Control Properties

Question

User-277742030 posted

 I've Created my custom server control, it contains Devexpress controls,  here is example

 

public class CustomPivot : CompositeControl
    {
        ASPxPivotGrid _Grid = new ASPxPivotGrid();
        public ASPxPivotGrid Grid
        {
            set { _Grid = value; }
            get { return _Grid; }
        }
        
        ASPxComboBox _TemplateCombo = new ASPxComboBox();
        public ASPxComboBox TemplateCombo
        {
            set { _TemplateCombo = value; }
            get { return _TemplateCombo; }
        }

        protected override void CreateChildControls()
        {
            Panel P = new Panel();
            P.Controls.Add(new LiteralControl("&lt;table><tr><td>"));
            P.Controls.Add(TemplateCombo);
            P.Controls.Add(new LiteralControl("&lt;/td></tr><tr><td>"));
            P.Controls.Add(Grid);
            P.Controls.Add(new LiteralControl("&lt;/td></tr></table>"));

            Controls.Add(P);
        }
    }

everything works fine but when I put my control on form I need to change properties not only from designer, I need them to be visible like this

 
<cc1:CustomPivot ID="CustomPivot1" runat="server">        
    <ChildrenControls>
        <MyPivotGrid ID="ASPxPivotGrid1" runat="server">
        <Fields>
            ...
            ...
            ...
        </Fields>
        <OptionsData />
        </MyPivotGrid>

        <MyComboBox ID="ASPxComboBox1" runat="server">
        <Items>
            ...
            ...
            ...
        </Items>
        <MyComboBox>
    </ChildrenControls>
 </cc1:CustomPivot>
  How can I achieve this goal?
