MSDN / DirectX SDK has tons of information for you. Specifically, try Mesh and look at the "FromFile" static method.

    // Begin loading a mesh    ExtendedMaterial[] mtrl;    private Material[] meshMat;    private Texture[] meshTex;    Mesh sysMesh = Mesh.FromFile("fileName.x", MeshFlags.Managed, device, out           mtrl);   //store mesh materials   if ((mtrl != null) && (mtrl.Length > 0))   {        meshMat = new Material[mtrl.Length];        meshTex = new Texture[mtrl.Length];        for (int i = 0; i < mtrl.Length; i++)        {             meshMat = mtrl.Material3D;             if ((mtrl.TextureFilename != null) && (mtrl.TextureFilename                 != string.Empty))             {                 //There's a texture, load it                 meshTex = TextureLoader.FromFile(device,                       mtrl.TextureFilename);             }         }    }

Basically you need to not only load the mesh, but also keep all your textures and materials stored for your drawSubset calls when you render the mesh. Hope this helps.

I just had to run through a skinned me myself. The problem is that you have to have an derived classes for about everything you will use when you animate (Frame, AllocateHeirarchy, MeshContainer, etc...). You then have to override all of the functions in the AllocateHeirarchy derived class so that you can load the frames, meshes, and textures. It's a long drawn out process, and there is something in the SDK about it. I believe it's called simple animation. It came with the June SDK, and if I remember, pretty much everyone since summer 2004. Elsewise, just load it like it says. AnimtionRoot = Mesh.LoadHierarchyFromFile(string for file, meshflags, device, (the derived heirarchy), null(don't know what it's for));

Ok, tnx.
Now i would try to load my mesh inside a panel of my windows c# form.
How could i do?

i use this code:

		public void OnResetDevice(object sender, EventArgs e)		{			ExtendedMaterial[] materials = null;			Directory.SetCurrentDirectory(Application.StartupPath + @"\");			Device dev = (Device) sender;			dev.RenderState.ZBufferEnable = true;			dev.RenderState.Ambient = System.Drawing.Color.White;			mesh = Mesh.FromFile("tiger.x", MeshFlags.SystemMemory, device, out materials);			if(meshTextures == null)			{				meshTextures = new Texture[materials.Length];				meshMaterials = new Direct3D.Material[materials.Length];				for(int i=0; i<materials.Length; i++)				{					meshMaterials = materials.Material3D;					meshMaterials.Ambient = meshMaterials.Diffuse;					meshTextures = TextureLoader.FromFile(dev, materials.TextureFilename);				}			}		}

It should be cool convert panel to device...
Device dev = (Device) sender;
Device dev = (Device) mypanel; // ERROR
