Hello,

I've search high and low for help on what I am trying to do, which seems pretty simple.

Basically, I want to create a number of RadDocks depending upon how many rows I have in a table which holds photos and data associated with them.  I am trying to add a few buttons to the RadDock that will do stuff, like delete a photo.

Here is what I have so far:

DataTable dtPhotos = GetAllByGalleryID(ID);
 
        if (dtPhotos.Rows.Count > 0)
        {
            foreach (DataRow dr in dtPhotos.Rows)
            {
                RadDock dock = new RadDock();
                dock.ID = "rd" + dr["ID"].ToString();
                dock.Title = "<div style=\"position:relative; top:7px; height:70px;\"><img class=\"galleryPhoto\" src=\"/properties/images/" + dr["ImgName"].ToString() + "\" /></div>";
                dock.EnableDrag = true;
                dock.DockMode = DockMode.Docked;
                dock.UniqueName = Guid.NewGuid().ToString();
                dock.EnableEmbeddedSkins = false;
                dock.Width = Unit.Pixel(100);
                dock.Height = Unit.Pixel(75);
                dock.DefaultCommands = Telerik.Web.UI.Dock.DefaultCommands.Close;
                 
                dock.ContentContainer.CssClass = "photoButtons";
 
                Button delete = new Button();
                delete.Text = "Delete";
                delete.CssClass = "deleteButton";
 
                delete.Command += new DockCommandEventHandler(DeletePhoto);
                delete.CommandArgument = dr["ID"].ToString();
                delete.CommandName = "DeletePhoto";
                delete.OnClientClick = "return confirm('Are you sure you want to delete this photo?')";
 
                dock.ContentContainer.Controls.Add(delete);
 
                RadDockLayout1.Controls.Add(dock);
                dock.Dock(rdz1);
            }
        }


How do I wire up a simple Button inside the RadDock to an Event Handler?

Hello Andrew,

Please verify if the RadDock controls are created on Page_Init. Also, if the docks are recreated after the postback, you should attach the button's event handler again.

Kind regards,
