Cant unload TreeMenuItems

[Tiago]

Hello.

In my software I have a menu and a submenu. I fill in as follows:

    For Each dr As DataRow In ds.Tables("VERPRO_NEWSLETTERS_CAT").Rows

            Dim x As New Syncfusion.Windows.Forms.Tools.TreeMenuItem

            x.Text = dr.Item("Descricao").ToString

            x.Font = Fonte

            x.SelectedColor = Color.FromArgb(0, 169, 172)

            x.SelectedItemForeColor = Color.White

            TreeNavigator1.Items.Add(x)

            dsRow.Clear()

            Dim da As New OleDbDataAdapter("Select * FROM VERPRO_NEWSLETTERS where fam like'" & dr.Item(1).ToString & "'", cnAdoNetConexao)

            da.Fill(dsRow, "VERPRO_NEWSLETTERS")

            For Each dr2 As DataRow In dsRow.Tables("VERPRO_NEWSLETTERS").Rows

                Dim x2 As New Syncfusion.Windows.Forms.Tools.TreeMenuItem

                x2.Text = dr2.Item(3).ToString

                x2.Font = Fonte2

                x2.SelectedColor = Color.FromArgb(0, 169, 172)

                x2.SelectedItemForeColor = Color.White

                x.Items.Add(x2)

            Next

When the user clicks on a button, it loads again with other items.

My problem is when the user is in the submenu, it doesn't go back to the beginning. It gets stuck the "x2" TreeMenuItem filled.

Hi Tiago,

Thank you for contacting Syncfusion support.

We have checked your reported query in TreeNavigator. Based on the provided information, we have added the items in TreeNavigator and also added item at run time through a button but we were unable to reproduce the issue as the we could navigate back and forth in the TreeNavigator. We have attached the sample below with which we tried to reproduce the issue. Can you please check and let us know whether we have missed any settings or have we misunderstood your query as it will help us to further proceed with this.

Hi Tiago,

Thanks for your update.

We were able to reproduce the reported issue and notice that the child items are not cleared properly and hence the option to navigate in the TreeNavigator is also disappeared. We have logged a bug report on this and it can be tracked through our feedback portal below.

We will fix the reported issue and will provide you a patch in version 17.3.0.14 by December 20, 2019. Incase if you are using a different version, then please let us know so that we will be able to provide the patch in that version.
