    [CLOSED] [#604] Tree node is selected when it's expanded

    On version 3.x, the behaviour of tree node has changed. At this version, the node is selected when it's expanded.

    On the following example, expand "Housewares" node. The node was selected
    https://examples3.ext.net/#/TreePane...nced/TreeGrid/

    On the same version 2.x example, expand "Housewares" node. The node was not selected
    https://examples3.ext.net/#/TreePane...nced/TreeGrid/

    My application performs some actions (Bind the record to the form, etc) when the node is selected, so i need to overcome the problem presented above.

    Thanks in advance.

    Hi Raphael,

    Thank you for the report. Created an Issue:
    https://github.com/extnet/Ext.NET/issues/604

    It is already reported to Sencha.
    http://www.sencha.com/forum/showthread.php?289477

    According to ExtJS 5.1.0 beta release notes, it has been fixed.
    http://cdn.sencha.com/ext/beta/ext-5...ase-notes.html

    So, it will be fixed in Ext.NET with the next upgrade of ExtJS.

    Do you have any timeframe for upgrading ExtJs?

    We depend on Sencha here.

    Sencha released ExtJS 5.1.0 beta on November 27.
    http://www.sencha.com/forum/showthre...a-Is-Available!

    We would expect that ExtJS 5.1.0 final should be released already, but it is not. Unfortunately, Sencha doesn't provide any official time frames, but, I think, the final release should appear any day now. Once it is released, it will take a few weeks to incorporate it to Ext.NET.

    Aha:) Thank you for the information.

    We will probably release Ext.NET v3.0 final with ExtJS 5.0 very soon. Then we will start to incorporate ExtJS 5.1.

    I was not able to overcome the issue presented on this thread by applying the fix suggested on: http://www.sencha.com/forum/showthread.php?284220. An exception is thrown.

    So i would like to suggest the following approach: Override Ext.grid.NavigationModel' onCellClick and validate if the event's target is the row expander, as shown below (Line 7):

    <!DOCTYPE html>
<html>
<head id="Head1" runat="server">
    <script type="text/javascript">
        Ext.override(Ext.grid.NavigationModel, {
            onCellClick: function (view, cell, cellIndex, record, row, recordIndex, clickEvent) {
                if (Ext.isEmpty(clickEvent.target.className) || clickEvent.target.className.indexOf("expander") < 0) {
                    if (this.position.isEqual(clickEvent.position)) {
                        this.fireNavigateEvent(clickEvent);
                    } else {
                        this.setPosition(clickEvent.position, null, clickEvent);
                    }
                }
            }
        });
    </script>
</head>
<body>
    <ext:ResourceManager ID="ResourceManager1" ScriptMode="Debug" runat="server" />
    <ext:TreePanel RootVisible="false" Title="Ext.Net" Height="700" Width="500"
        Margin="10" Border="false" runat="server">
        <Store>
            <ext:TreeStore runat="server">
                <Proxy>
                    <ext:AjaxProxy Url="/Example/LoadTreeFakeChildren">
                        <ActionMethods Read="POST" />
                        <Reader>
                            <ext:JsonReader RootProperty="data" />
                        </Reader>
                    </ext:AjaxProxy>
                </Proxy>
                <Model>
                    <ext:Model runat="server">
                        <Fields>
                            <ext:ModelField Name="Name" />
                        </Fields>
                    </ext:Model>
                </Model>
            </ext:TreeStore>
        </Store>
        <Root>
            <ext:Node NodeID="0" Text="Root" />
        </Root>
        <ColumnModel>
            <Columns>
                <ext:TreeColumn Text="Name" DataIndex="Name" Flex="2" runat="server" />
            </Columns>
        </ColumnModel>
    </ext:TreePanel>
</body>
</html>
    public class ExampleController : System.Web.Mvc.Controller
{
    public ActionResult Index()
    {
        return View();
    }
    public StoreResult LoadTreeFakeChildren()
    {
        NodeCollection nodes = new NodeCollection(false);

        for (int index = 1; index < 6; index++)
        {
            Node node = new Node();
            node.NodeID = index.ToString() + DateTime.Now.Second;
            node.CustomAttributes.Add(new ConfigItem { Name = "Name", Value = node.NodeID, Mode = ParameterMode.Value });
            nodes.Add(node);
        }

        return new StoreResult { Data = nodes.ToJson() };
    }
}

    Note: This is a temporary fix, since Sencha stated that it has been fixed on version 5.1.0, which will be incorporated to Ext.Net soon
