问题 How can I create a template in c# for an AXPxGridViewDataTextColumn without any markup and with using Eval to display the DataItem value? -The problem that I am having is that the string "<%#Eval("dataTableField1")%>" shows up in the GridView for every row instead of the appropriate values.

问题 I'm using devexpress's gridview-control for showing information about files. You have to select a folder, and then the gridview is going to show the information, like this: name|date|size but I can't get it done to add a new row to the gridview. The name of it is gdFiles for example, but what would the command for adding a new line be? Something like gdFiles.insert(x,y,z)? 回答1: You can always use methods of your data source to add, delete and modify individual rows if the data source supports

问题 I am using DevExpress control within an ASP.NET MVC 4 project. I am using unbound columns in the GridView extension for ASP.NET MVC. In the CustomUnboundColumnData event handler, the e.GetListSourceFieldValue always returns null for me. I then tried getting the value directly from the model instead of calling this method (please see the commented line just above the call to the method) but even though that worked, it had side-effects, which I won't get into just now. I am using ASP.NET MVC 4

问题 I know I can invoke filter editor and so on. But this is not a convenient thing, especially for non technical users. Can GridView continually display a nice filter field for a group column as it does for normal columns? I know I can roll my own via filtering on a hidden column and so on, but that's a lot of work. Maybe there is a built-in way to do this instead? 回答1: Set the GridView.OptionsView.ShowGroupedColumns property to true, the group column will be also shown in the column header

问题 I try to bind a List property SubscribedSymbols within a class object StrategySubscription as part of List to comboboxes in each cells of a specific column in a Devexpress GridControl but cannot get the data binding to work. The auto column generator works and populates values onto the grid. So, I am sure the data exists. I attached the xaml code and data object as well as a screenshot of the current output. Can you please help to get the data binding to work correctly? I want the collection
