How to have databind nodes inside declarative node?

[Tiago]

Hello,

I've searched and didn't find an answer to have a default node, and then add all the binding nodes inside that on an declarative fashion.

I've come up with a solution but uses server side code:

<telerik:RadTreeView ID="trvEntities"
                        runat="server"
                        DataSourceID="dataSourceEntities"
                        DataFieldID="Id"
                        AppendDataBoundItems="true"
                        OnNodeDataBound="trvEntities_NodeDataBound">
    <DataBindings>
        <telerik:RadTreeNodeBinding TextField="Name" Depth="0" />
    </DataBindings>
    <Nodes>
        <telerik:RadTreeNode Expanded = "true" Text="Select an Entity" Value="-1" />
    </Nodes>
</telerik:RadTreeView>

protected void trvEntities_NodeDataBound(object sender, RadTreeNodeEventArgs e)
{
    trvEntities.Nodes.Remove(e.Node);
    trvEntities.Nodes[0].Nodes.Add(e.Node);
}

Thanks in advance!

Hi Tiago,

I am a bit confused (mainly from the code that you provided) in what exactly do you try to achieve.
Could you, please, further explain it in more detail?

Hello Nikolay,

What I really want is the ability to do something like this:

<telerik:RadTreeView ID="trvEntities"
                        runat="server"
                        DataSourceID="dataSourceEntities"
                        DataFieldID="Id"
                        AppendDataBoundItems="true"
                        OnNodeDataBound="trvEntities_NodeDataBound">
    <Nodes>
        <telerik:RadTreeNode Expanded = "true" Text="All Entities" Value="0">
            <DataBindings>
                <telerik:RadTreeNodeBinding TextField="Name" />
            </DataBindings>
        </telerik:RadTreeNode>
    </Nodes>
</telerik:RadTreeView>

So, this tree will be something like this:

+ All Entities
   |Entity1
   |Entity2
   |Entity3

I've managed to do it with the code-behind, but is there any declarative way to do this?

Thanks!

Hello Tiago,

I don't thing there is an alternative way.
