Hi ..
I am using the treeview with a context menu which has a 'Delete' option.
I use the following code:
var Node;//global node
function ShowContextMenu(e, treeView, node)
{
Node = node;
var menu = eo_GetObject("<%=Menu1.ClientID%>");
menu.getTopGroup().getItemByIndex(0).setText("Delete '" + node.getText() + "'");
eo_ShowContextMenu(e, "<%=Menu1.ClientID%>");
return true;
}
function ItemClick(e,info)
{
Node.setCheckState(0);
Node.setVisible(false);
Need to do the same to the node's child nodes here !!
}
I want the treeview to set check state and visibility of all child nodes under the one I've 'deleted' .. how can I do this? At the moment only the root node is affected ?

Hi, You do not need to call setVisible on child nodes since visually when the parent node is invisible, all child nodes are invisible. If you wish to clear check state for all child nodes, you can do it recursively, it will be something like this:
Code: JavaScript
function ClearCheckState(node)
{
//Clear check state for this node
node.setCheckState(0);
//Clear check state for all child nodes
var subGroup = node.getSubGroup();
if (subGroup)
{
for (var i = 0; i < subGroup.getItemCount(); i++)
{
var childNode = subGroup.getItemByIndex(i);
ClearCheckState(childNode);
}
}
}
Hope this helps. Thanks!

Hi..thanks for that... my tree certainly wasn't hiding child nodes.... but the code you provided with some modifications has enabled me to work around it ...thanks.
