问题 Why would you construct a new DataView instead of using the DefaultView of the DataTable in C#? What are the scenarios creating a new DataView is preferable? What are the advantages and disadvantages of both? var dataView = new DataView(dataTable); vs var dataView = dataTable.DefaultView; 回答1: The DefaultView has the advantage of being there already by default, as the name implies. Additional DataViews have the advantage of allowing you to keep several of them ready and in use in parallel .

问题 We're currently using the slick.remotemodel.js model implementation of SlickGrid for its remote Ajax loading functionality. With this example the only filtering provided is a simple Search element. What we're looking to accomplish is a much more robust filtering method of each column, such as what is used in this example: http://mleibman.github.com/SlickGrid/examples/example-header-row.html Is there a way to easily combine the features of the Dataview model with the RemoteModel? Is it merely

问题 Can or how to convert DataRow to DataRowView? For example: DataTable dt=ds.Tables[0]; DataRow dr= dt.NewRow(); DataRowView drv = ???? 回答1: Use DataTable dt=ds.Tables[0]; DataRow dr= dt.NewRow(); DataRowView drv= dt.DefaultView[dt.Rows.IndexOf(dr)]; 回答2: The above method does not work if the DataRow status is Detached. This code snippet could be used in such case: DataRow dRow = dataTable.NewRow(); //... DataRowView dRowView = dRow.Table.DefaultView.AddNew(); for (int i = 0; i < dRow.ItemArray

问题 How to find a value of some column from DataView.CurrentItem. 回答1: As Paul pointed out in his comment, there is no CurrentItem member in the DataView class. If you know the index of the item, you can access a column by its name as shown below : string name = dataView[index]["Name"] as string; Similarly, if you have an instance of a DataRowView (a view of a DataRow ), you can do that : string name = dataRowView["Name"] as string; EDIT: I just noticed the WPF tag on your question... perhaps you

问题 I have this row filter text: "[Name 1] = '" + forename + "%" + surname + "'" which fails, but if I put the % at the beginning or end it's OK. Is there any way to achieve the same result (i.e. "any" string in the middle of the names)? Full statement is: dv = new DataView(MyDataTable, "[Name 1] = '" + forename + "%" + surname + "'", "", DataViewRowState.CurrentRows); 回答1: Just a free thougth, try: dv = new DataView(MyDataTable, "[Name 1] = '" + forename + "%' AND [Name 1] = '%" + surname + "'",
