由 谁都会走 提交于 2019-12-08 11:58:02

When combining asp.net Dynamic Data and MVC MetaModel.Visible contains tables with Scaffold==false

由 我的未来我决定 提交于 2019-12-08 00:39:24
问题 I combined MVC and DD by creating a new DD project and adding the MVC stuff (references, routing, usings, etc). The list of tables on default.aspx (from DD) will show all tables, including the ones with [ScaffoldTable(false)]. The URL's of the tables with Scaffold==true have the expected form (DD/TableName/List.aspx). However, the URL's of the tables that should not be shown are in the form /Home/List?Table=TableName.

How do I hide a column only on the list page in ASP.NET Dynamic Data?

由 橙三吉。 提交于 2019-12-06 11:52:42
问题 This is somewhat similar to this question. However, rather than wanting to hide a column all together, I am just looking to hide the column on the List.aspx page. My specific example is that fields that are long (or at least nvarchar(MAX)) automatically hide from the List.aspx page as is but are still visible on the Edit.aspx page. I would like to replicate this behaviour for other (shorter) columns. Is this possible? 回答1: You can create a custom page for the particular table you want to

Sorting by multiple fields using DisplayColumnAttribute in Asp.Net Dynamic Data App?

由 五迷三道 提交于 2019-12-06 09:06:16
问题 I've got a dynamic data app, and I want to sort based on multiple fields like so.. <DisplayColumn("FieldName", "Field1, Field2")> _ DisplayColumn doesn't seem to support more than one field? 回答1: The DisplayColumn attribute's SortColumn param specifies the column that will be used to sort this entity when it is used as a foreign key (ex: in a DropDownList), not when it is being sorted in the GridView (or being sorted in the DB). see SO here as well: ASP.NET Dynamic Data DisplayColumn
