An interesting challenge I faced was programmatically exposing custom folder metadata within a specific Document Library View, for specific Folder Content Types.<\/p>\n
As background, I already created Folder Content Types, deriving from the SharePoint Folder Content Type, to which I added appropriate metadata.<\/p>\n
These new Content Types were syndicated from a Content Type Hub, and propagated across the enterprise.<\/p>\n
I extended the ASP template to include a table that I will build dynamically and a button that I optionally hide:<\/p>\n
\r\n<\/asp:Table<>asp:Button ID=\"PlaceholderButton\" runat=\"server\" Text=\"Create New Placeholder\" onclick=\"PlaceholderButton_Click\" \/><\/pre>\nI then add an action for the button:<\/p>\n
protected void PlaceholderButton_Click(object sender, EventArgs e) \r\n {\r\n Response.Redirect(\"http :\/\/SharePoint\/div\/myDiv\/Lists\/MyListTasks\/NewForm.aspx?RootFolder=\"); \r\n }<\/pre>\nThis useful function adds a table row consisting pair of table cells with a property label (in bold) and the property value, but only if the property\/value is found, on the current Document. Note Content Type is detected and handled separately:<\/p>\n
void push_property(string myLabel, string propertyName)\r\n {\r\n try\r\n {\r\n string val = null;\r\n if (propertyName == \"ContentType\")\r\n val = folder.Item.ContentType.Name;\r\n else\r\n val = folder.Item.Properties[propertyName].ToString();\r\n \r\n if (!String.IsNullOrEmpty(val))\r\n {\r\n TableRow rw = new TableRow();\r\n TableCell cel = new TableCell();\r\n cel.Text = string.Concat(\"\", myLabel, \"<\/b>\");\r\n \r\n rw.Cells.Add(cel);\r\n cel = new TableCell();\r\n cel.Text = val;\r\n rw.Cells.Add(cel);\r\n Table1.Rows.Add(rw);\r\n }\r\n \r\n }\r\n catch { }\r\n \r\n }<\/pre>\nThis is the heart of this little web-part. I derive the actual folder from the user context, by extracting it from the browser URL string using Page.Request.QueryString[\u201cRootFolder\u201d]:<\/p>\n
protected void Page_Load(object sender, EventArgs e)\r\n{\r\n bool ok = true;\r\n string ctName = null;\r\n \r\n SPWeb web = SPContext.Current.Web;\r\n string rootFolder = Page.Request.QueryString[\"RootFolder\"];\r\n \r\n \/\/Label2.Text = rootFolder;\r\n \r\n if (String.IsNullOrEmpty(rootFolder))\r\n ok = false;\r\n \r\n \r\n if (ok)\r\n {\r\n folder = web.GetFolder(rootFolder);\r\n if (!folder.Exists)\r\n ok=false;\r\n }\r\n \r\n if (ok)\r\n {\r\n ctName = folder.Item.ContentType.Name;\r\n \r\n if ((ctName != \"Divison Acct Folder\") && (ctName != \"Divison Common Folder\"))\r\n ok=false;\r\n }\r\n \r\n PlaceholderButton.Visible = ok; \/\/reacts dynamically, needs setting in both directions, as it maintains state\r\n \r\n if (ok)\r\n {\r\n \/\/push_property(\"Folder Type\", \"ContentType\"); \/\/Handled in special fashion internal to function\r\n push_property(\"Claimant\", \"Claimant\"); \r\n push_property(\"Account Number\", \"AccountNumber\");\r\n push_property(\"Issue Description\", \"IssueDescription\");\r\n \r\n \/*Only apply this border logic if you want a griddy view\r\n if (Table1.Rows.Count > 0)\r\n {\r\n Table1.GridLines = (GridLines) 3;\r\n }\r\n *\/\r\n }\r\n \r\n}<\/pre>\n","protected":false},"excerpt":{"rendered":"Creating a Folder Metadata Web Part An interesting challenge I faced was programmatically exposing custom folder metadata within a specific Document Library View, for specific Folder Content Types.
