Hi @hdsoso,

Please try:

tree.getStore().reload();

[ViDom]

Hi @hdsoso,

Please try:

tree.getStore().reload();

In code behind it should be in this case:

Ext.Net.X.Js.AddScript(this.menu_tp.ClientID+".getStore().reload();");

[hdsoso]

In code behind it should be in this case:

Ext.Net.X.Js.AddScript(this.menu_tp.ClientID+".getStore().reload();");

after reload, there is no leaf node
plz see screen capture.

Hello!

I think you send back to the client wrong nodes collection. Please, double check you send all data to the client on reload.

Hello!

I think you send back to the client wrong nodes collection. Please, double check you send all data to the client on reload.

I think data of nodes collection is ok,becuase reopen the tab, the tree is ok through the screen capture.
ashx code is

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using ExtDemoEf;
using System.Text;

the str sample data is

Try to add listener to the TreeStore:

<ext:TreeStore runat="server" ID="menu_store" >
	<Root>
		<ext:Node Text="???" Expanded="True">
			<CustomAttributes>
				<ext:ConfigItem Name="id" Value="-1" runat="server" />
				<ext:ConfigItem Name="name" Value="???" runat="server" />
				<ext:ConfigItem Name="pid" Value="-1" runat="server" />
				<ext:ConfigItem Name="url" Value="" runat="server" />
			</CustomAttributes>

		</ext:Node>

	</Root>
	<Proxy>
		<ext:AjaxProxy Url="TreeLoader.ashx" Json="True">
		</ext:AjaxProxy>
	</Proxy>
	<Model>
		<ext:Model runat="server" IDProperty="id">
			<Fields>
				<ext:ModelField runat="server" Name="id"></ext:ModelField>
				<ext:ModelField runat="server" Name="name"></ext:ModelField>
				<ext:ModelField runat="server" Name="pid"></ext:ModelField>
				<ext:ModelField runat="server" Name="url"></ext:ModelField>
			</Fields>
		</ext:Model>
	</Model>
	<Listeners>
		<Load Handler="#{menu_tp}.view.refresh();"></Load>
	</Listeners>
</ext:TreeStore>

Confirm, a refresh call help. It might be better to call it withing a callback.

App.menu_tp.getStore().reload({
    callback: function () {
        App.menu_tp.view.refresh();
    }
})

Though. obviously a refresh call should not be required. I think it is a bug, reported here:

Sencha opened a bug. We created an Issue to monitor.
