Selected node route generation not working correctly

[Bulmaro R]

I am trying to generate the node route but it is not being generated correctly. I'm using this post metodo https://blazor.syncfusion.com/documentation/treeview/node-selection#get-path-of-selected-node

I am generating the tree dynamically but when the ParentId is established the node stays loading, 

For now I only left the property Child="@("Child")"

Another question: is there any way to add some other extra property to each node? I tried to add it but when selecting it it does not bring the property

Hi Bulmaro,

We have prepared a sample to meet your requirements by making the necessary changes in the referred sample. Kindly check the code changes below,

[Query: 1 – Route generation]

[Index.razor]

 

@{

    string path = "";

    for (int i = ParentIdArray.Length - 1; i >= 0; i--)

    {

        path += ParentTextArray[i];

        if (i > 0)

        {

            path += "/";

        }

    }

}

<p>@path</p>

 

public void NodeSelected(NodeSelectEventArgs args)

{

 

    List<string> IdList = new List<string>();

    List<string> TextList = new List<string>();

    IdList.Add(args.NodeData.Id);

    TextList.Add(args.NodeData.Text);

   …

}

[Query: 2 – Get the additional properties of nodes]

<SfTreeView TValue="MusicAlbum" AllowMultiSelection="true" @ref="tree" @bind-SelectedNodes="SelectedNodes">

    <TreeViewEvents TValue="MusicAlbum" NodeSelected="NodeSelected"></TreeViewEvents>

</SfTreeView>

 

public void NodeSelected(NodeSelectEventArgs args)

{

    …

    var TreeData = tree.GetTreeData();

}

We have attached the sample for your reference,
