PropertyGrid needs at least one item hard coded in the markup otherwise won't add new items on DirectEvent

[paul-2011]

Hi, if I create a simple PropertyGrid and try to add items using DirecEvent it won't work if at least one item exists in the markup, could you please check my code? Btw, I found some working solutions in the forum but when I use them the editor does not work.

<ext:PropertyGrid ID="PropertyGrid1" Border="false" runat="server" AutoWidth="true"            AutoHeight="true" Shim="True" StripeRows="True">
            <Source>
                <ext:PropertyGridParameter Name="" Value="" Mode="Value" />
            </Source>
            <View>
                <ext:GridView ID="GridView2" ForceFit="true" runat="server" />
            </View>
        </ext:PropertyGrid>

for (int i = 0; i < 15; i++)        {     
            PropertyGridParameter param = new PropertyGridParameter();
            param.Name = i.ToString();
            param.DisplayName = "Param " + (i + 1).ToString();
            param.Value = Guid.NewGuid().ToString();            


            TriggerField trig = new TriggerField();
            trig.Editable = false;
            FieldTrigger fltrig = new FieldTrigger();
            fltrig.Icon = TriggerIcon.SimpleEllipsis;            
            trig.Triggers.Add(fltrig);
            trig.Listeners.TriggerClick.Handler = "alert('clicked me');";


            param.Editor.Add(trig);
            PropertyGrid1.AddProperty(param);
            //this.PropertyGrid1.Source.Add(param);
            //this.PropertyGrid1.SetSource(this.PropertyGrid1.Source);
        }
