[Solved] Change load on demand behaviour clientside

[Relatics Systeembeheer]

Hi,

I have the following problem:

Scenario 1:
In my onload procedure I create a radtreeview and two root nodes:
node one has expandMode Serversidecallback
node two has no specific setting for expandMode.

In this scenario, I can easily change the loadondemand behaviour on the client of node two and dynamically expand the node:
nodeTwo.set_expandMode(2);
nodeTwo.expand();

Scenario 2:
create treeview with two rood nodes:
node one has no specific setting for expandMode.
node two has no specific setting for expandMode.

In this scenario, changing de expandMode property on the client does not result in a fireing the NodeExpand on the server.

Conclusion: It seems that at least one node must have the Serversidecallback value to function properly

Is this correct? In our case there are numerous situations where this is the case.

Hello Bert Groenveld,

Here is a workaround that you can use:

Add this line in your Page_Load event:

protected void Page_Load(object sender, EventArgs e)
{
    Page.ClientScript.GetCallbackEventReference(RadTreeView1, null, null, null);
}

I hope this helps.

I updated your Telerik points.
