Treeview, event and databinding


S

For a CMS, I use the treeview control with CSS friendly adapter binded with
the sitemap :

<asp:TreeView DataSourceID="SiteMapDataSource1" ID="EntertainmentTreeView"
runat="server" OnSelectedNodeChanged="OnClick"
OnAdaptedSelectedNodeChanged="OnClick" >
<DataBindings>
<asp:TreeNodeBinding DataMember="SiteMapNode" TextField="Title"
ValueField="url" />
</DataBindings>
</asp:TreeView>

<asp:SiteMapDataSource ID="SiteMapDataSource1" runat="server" />

But when I click on a node, the treeview does not respond, doesn't send
event. If I replace the ValueField "url" by for example "title", the event is
ok.

How can I force the treeview to send Event with ValueField="url" ?

You can see a sample at www.almageste.info/preuve2.zip.

Thanks for your help !

And the Sitemapdatasource is:

<?xml version="1.0" encoding="utf-8" ?>
<siteMap xmlns="http://schemas.microsoft.com/AspNet/SiteMap-File-1.0" >
<siteMapNode url="" title="" description="">
<siteMapNode url="url1.aspx" title="url title 1" description="description 1"
/>
<siteMapNode url="url2.aspx" title="url title 2" description="description 2"
/>
</siteMapNode>
</siteMap>

Are you trying to use the Treeview as a menu? If so, you don't have to be
sneaky. Just set the NavigateUrl property to the URL.

Peace and Grace,

I don't want to use NavigateURL and I don't use the Treeview as a menu. I
want just click on a leaf and send an event to the onclick method. This
program works fine without CSS Friendly but not with.

I have tried many forums but you are my last chance !

Thanks for your help !
