Deploy a custom master template

<Module Name="MasterPages" List="116" Url="_catalogs/masterpage"> <File Url="Litware.master" Type="GhostableInLibrary" /> </Module> protected void cmdApplyCustomBrand_Click(object sender, EventArgs e) { SPWeb site = SPContext.Current.Site.RootWeb string MasterUrlPath = site.ServerRelativeUrl; if (!MasterUrlPath.EndsWith(@"/")) MasterUrlPath += @"/"; MasterUrlPath += @"_catalogs/masterpage/Litware.master"; ApplyCustomBrand(MasterUrlPath, site); } protected void ApplyCustomBrand(string MasterUrlPath, SPWeb site) { site.MasterUrl = MasterUrlPath; site.Update(); // use recusion to update all child sites in site collection foreach (SPWeb child in site.Webs) { ApplyCustomBrand(MasterUrlPath, child); } }

However, the ApplyCustomBrand method has also been written to enumerate through all child sites below the top-level site and recursively call itself to update them. This recursion continues to crawl the hierarchy of child sites until the MasterUrl property of every site within the site collection is updated to redirect all site pages so that they link to the instance of litware.master that is provisioned in the Master Page gallery of the top-level site.
