[Solved] How to bound hierarchy structure that is not DataSet?

[Raymond]

Hi
        

                I am using RadControls for WinForms Q2 2010 SP1 in .NET 3.5.            

                I would like to bound hierarchy structure to RadGridView that is not DataSet.            

                My structure is quite simple:      

            1. On the top is class ContentTargetFolder:
    
            

public class ContentTargetFolder
{
    private string _name;
    public string Name { get { return _name; } }
    /*…here I have other properties to display*/
    private List<Package> _packages;
    public List<Package> Packages { get { return _packages; } }
    …
}

 

            2. Package class:

public class Package
{
    /*…Properties to display…*/

    private List<PackageItem> _packageItems = new List<PackageItem>();
    public List<PackageItem> PackageItems { get { return _packageItems;}}
    …
}

        3. PackageItem class:

public class PackageItem
{
    /*…Properties to display…*/

}

 

                I have List< ContentTargetFolder> CTFs object and I do this:

this.radGridView1.BeginUpdate();
this.radGridView1.MasterTemplate.Reset();
this.radGridView1.AutoGenerateHierarchy = true;
this.radGridView1.DataMember = string.Empty;
this.radGridView1.DataSource = CTFs;
this.radGridView1.EndUpdate();

The problem is that I get flat list, Packages property from class ContentTargetFolder is displayed as normal property it is not treated as collection of objects.

How can I solve this problem?

Hi Raymond,

This functionality is not supported in the current edition of RadGridView control. The new object-relational hierarchy mode will be implemented and introduced in Q3 2010. 

Currently, you can manually make inner levels and child GridViewTemplates using bound or unbound mode. Please review the Hierarchy section of our Examples application.

Kind regards,
