Binding Json data to Kendo treeview MVC4 - json

Question

My Kendo Tree-view has many child nodes and sub nodes .Problem with getting sub child's nodes with redundant code
Here is my code .
nodes = rep.GetTreeViewData(CompanyId);
var productTreeData = nodes.Select(p => new
{
Text = p.CategoryName,
Url = p.ActionLink,
hasChildren = p.SubCategories.Any(),
// Expanded = true,
EntityType = p.EntityType,
Selected = currurl.ToLower() == p.ActionLink.ToLower() ? true : false,
ImageUrl = p.EntityType == "Company" ? "/Content/Images/company.gif" : "/Content/Images/geolocation1.gif",
Children = p.SubCategories.Select(c => new
{
Text = c.SubCategoryName,
Url = c.ActionLink,
// Expanded = true,
hasChildren = c.SubCategories.Any(),
EntityType = c.EntityType,
Selected = currurl.ToLower() == c.ActionLink.ToLower() ? true : false,
ImageUrl = c.EntityType == "Company" ? "/Content/Images/company.gif" : "/Content/Images/geolocation1.gif",
Children = c.SubCategories.Select(d => new
{
Text = d.SubCategoryName,
Url = d.ActionLink,
// Expanded = true,
hasChildren = d.SubCategories.Any(),
EntityType = d.EntityType,
Selected = currurl.ToLower() == d.ActionLink.ToLower() ? true : false,
ImageUrl = d.EntityType == "Company" ? "/Content/Images/company.gif" : "/Content/Images/geolocation1.gif",
Children = d.SubCategories.Select(f => new
{
Text = f.SubCategoryName,
Url = f.ActionLink,
//Expanded = true,
hasChildren = f.SubCategories.Any(),
EntityType = f.EntityType,
Selected = currurl.ToLower() == f.ActionLink.ToLower() ? true : false,
ImageUrl = f.EntityType == "Company" ? "/Content/Images/company.gif" : "/Content/Images/geolocation1.gif",
Children = f.SubCategories.Select(g => new
{
Text = g.SubCategoryName,
Url = g.ActionLink,
// Expanded = true,
hasChildren = g.SubCategories.Any(),
EntityType = g.EntityType,
Selected = currurl.ToLower() == g.ActionLink.ToLower() ? true : false,
ImageUrl = g.EntityType == "Company" ? "/Content/Images/company.gif" : "/Content/Images/geolocation1.gif",
})
})
})
})
});
This is my view
#(Html.Kendo().TreeView()
.Name("treeview-right")
.ExpandAll(true)
//.LoadOnDemand(false)
//.Events(events=>events.DataBound("DataBound"))
.DataSource(d => d
.Model(m => m
.HasChildren("hasChildren")
.Children("Children"))
.Read(r => r.Action("_ProductTree", "Home")))
.DataTextField("Text")
.DataUrlField("Url")
.DataImageUrlField("ImageUrl")
)
By this process am getting all child's and sub child's of individual parent up to four level hierarchy ..if i need another level i need to write one more children code.
Am struggling from 2 days to simplify this process .
Thanks

This looks like it could be solved with recursion. This should be pretty close.
var productTreeData = new ListofYourTreeViewModelHere();
foreach (var node in rep.GetTreeViewData(CompanyId))
{
productTreeData.Add(FillTree(node));
}
...
}
private YourTreeViewModelHere FillTree(p)
{
var tv = new YourTreeViewModelHere();
tv.Text = p.CategoryName,
tv.Url = p.ActionLink,
tv.hasChildren = p.SubCategories.Any(),
tv.EntityType = p.EntityType,
tv. Selected = currurl.ToLower() == p.ActionLink.ToLower() ? true : false,
tv.ImageUrl = p.EntityType == "Company" ? "/Content/Images/company.gif" : "/Content/Images/geolocation1.gif";
foreach(var sub in p.SubCategories)
{
tv.Children.Add(FillTree(x));
}
}
