Hi,
i'm using a treeview with checkbox and i don't be able to raise a callback when press on checkbox..
i've try to set RaisesServerEvent property but callback is raised only when i press on item text.
Thanks

Hi, It doesn't work that way. Checking/unchecking a node and clicking a node are two totally different things. Only the later raises ItemClick event. If you want to do anything when user checks/uncheck a node, you should handle the TreeView's ClientSideOnCheckStateChanging event: http://doc.essentialobjects.com/ViewDoc.aspx?book=1&t=EO.Web.TreeView.ClientSideOnCheckStateChanging.htmlIt will be something like this:
Code: HTML/ASPX
<eo:TreeView ClientSideOnCheckStateChanging="check_handler" ...>
....
</eo:TreeView>
Code: JavaScript
function check_handler(treeView, node, oldCheckState, newCheckState)
{
//Delay the real call until the TreeView has updated its internal
//state data. If you were to call on_check_changed directly
//from here, the TreeView would have been still in the old check
//state
window.setTimeout(
function()
{
on_check_changed(treeView, node, oldCheckState, newCheckState);
}, 10);
}
function on_check_changed(treeView, node, oldCheckState, newCheckState)
{
//do whatever you'd like to do here such as posting
//back the page or cause an AJAX callback...
//......
}
Note on_check_changed is a JavaScript function that runs on the client side. So if you wish to perform anything on the server side, you will need to raises a post back or a callback from there. You can call eo_Callback to raises an AJAX callback: http://doc.essentialobjects.com/ViewDoc.aspx?book=1&t=JSDoc.Public.Global.eo_Callback.htmlHope this helps. Thanks!
