Load RadTreeViewItem

[jean michel]

Hello,

I need to cover nodes of my treeview. Nodes is objects of the DtoHierarquiaAgrupamento class.
 
It follows the code below:

 foreach (Telerik.Windows.Controls.RadTreeViewItem item in RadHierarquia.Items)
                {

                    //codeblock
                }

 
Error:

Unable to cast object of type 'CCM7.DTO.DtoHierarquiaAgrupamento' to type 'Telerik.Windows.Controls.RadTreeViewItem'.

Thanks..!

Hi jean michel,

RadHierarquia.Items collection contains items of type DtoHierarquiaAgrupamento. Therefore you need to modify the foreach like so:

foreach (DtoHierarquiaAgrupamento item in RadHierarquia.Items)
   {

        //codeblock
   }

or you can do it like so:

foreach (var item in RadHierarquia.Items)
    {

         //codeblock
    }

However, if you need to use the RadTreeViewItem containing the item, you can use the ContainerFromItemRecursive method of the RadTreeView:

RadTreeViewItem treeItem = myRadTreeView.ContainerFromItemRecursive(item);

Give this a try and let me know if it works for you.
