Treeview Binding

[Michel]

Is there a better way to filter unwanted nodes to appear in the Treview ?

All I found is this :

void wTree_TreeNodeDataBound(object sender, TreeNodeEventArgs e)
{
if (e.Node.Text == "Var")
{
e.Node.Parent.ChildNodes.Remove(e.Node);
}
}

Not very elegant or efficient...

Hi,
I would suggest you filter at datatable level.You must be databinding
dataset or datatable to treeview.Try something like this:
DataView myView =Dataset1.Tables[0].DefaultView;
myView.RowFilter = "Description LIKE '%" + strSearch.Text +
"%' or Model LIKE '%" + strSearch.Text + "%' ";

Hello,

I should have been more clear, sorry!

My XmlDataSource is loaded from an XML file which serves many purposes...

dataSource = new XmlDataSource();
dataSource.ID = "CatalogDataSource";
dataSource.DataFile = "xml/catalog.xml";
dataSource.XPath = "/Catalog/Cat";

I did not find a way to filter out unwanted nodes directly in the
dataSource...

"Catalog" is the root, "Cat" are categories nodes; I don't want other node
types.

I was hoping to be able to specify a filter in the XPath property ?

Thanks,
