ASP.NET 2.0: TreeView and Custom Paging

[Sachin]

Hi All,

I am using ASP.NET 2.0 Tree control to display hierarachical data.

However because of the size of the data, tree takes ages to load on the
browser.

For that reason, I want to build custom paging solution similar to custom
paging in datagrid/gridview...

Any pointer/help for how to build custom paging for Tree?

TIA
Sachin

You should look into using some Ajax solution for this kind of situation.
You should do demand load of nodes. You can load the first level of the node
when page loads. For subsequent levels on node clicks make http request to
get the data and then generate the node on client side. I don't know if MS
tree control has any demand load capabilities.

You might want to investigate a control that does load on demand:

I have used component art's tree control and it does a decent job of demand
load. Other than their poor technical support, component art's solution is
not bad to look at.
