how to store .csv file to particular path in mobile like /mnt/sdcard/csvfiles .

Scenario
In this example, we will create a WCF IDataStore service that will be used by our client (Console Application) as a data layer. Instead of the direct connection to the database, our client will connect to a remote service, which is way more secure and thus important in many enterprise scenarios as database connection settings are not exposed to the client.
Steps to implement
1. Create a new WCF Service Application project and add references to the DevExpress.Data and DevExpress.Xpo assemblies and remove files with auto-generated interfaces for the service.
2. Modify the service class as shown in the Service1 file. This service initializes a connection provider and stores it in the static DataStore property, which is then used by the base DataStoreService class.
3. Change some binding properties as shown in the example's web.config file. At this stage, the service part is ready to work and we need to implement a client to consume data from our data store service (for demonstration purposes, we will create a Console Application).
4. Add the Console Application into the existing solution.
5. Add a new code file for a Customer class using the DevExpress v1X.X ORM Persistent Object item template. See a code of Customer class in the ConsoleApplication\Customer code file.
6. Pass the address of our service into the GetDataLayer method of the XpoDefault class. For this, modify the Main method of the Console Application as shown in the ConsoleApplication\Program code file. Please note that the port number in the connection string may be different. You can check it in the properties of the service project in the Solution Explorer:
As a result, we will see the following output:
Important notes
If you are using an XAF client, then in the simplest case, you can just set the XafApplication.ConnectionString to the address of your data store service (http://localhost:55777/Service1.svc). Refer to the Connect an XAF Application to a Database Provider help article for more details.

FYI on this part "If you are using an XAF client, then in the simplest case, you can just set the XafApplication.ConnectionString to the address of your data store service (http://localhost:55777/Service1.svc). "
Literally do this:
WebApplication.Instance.ConnectionString = "http://localhost:55777/Service1.svc";
XpoDefault.DataLayer = XpoDefault.GetDataLayer("http://localhost:55777/Service1.svc",
AutoCreateOption.DatabaseAndSchema);
XpoDefault.Session = null;

For example, if there's three columns, if first column contains text, it'll get as wide as it needs to so it does not wrap the text, then second column is a checkbox, so can always be same width, then the last column must get wide enough so that it fills the rest of the grid's width.

This example demonstrates how you can add XtraReport to a Silverlight application and show its Document Preview from where it can be printed and/or exported to a variety of popular formats (notably PDF, HTML, MHT, RTF, TXT, CSV, XLS, XLSX, and XPS).
A document exporting is performed via a reporting service deployed on the server-side.
This sample contains two projects:
- SilverlightApplication1, providing functionality for the client-side Document Preview;
- SilverlightApplication1.Web, with the report service hosted on the server to generate reports.
NOTE: For this example to work correctly, SilverlightApplication1.Web must be set as a "Start Up Project" and the SilverlightApplication1TestPage.aspx must be set as a "Start Page".

This example illustrates how to share the same SiteMap between ASPxMenu and ASPxSiteMapControl placed to show information from different SiteMap node levels. Here are steps you need to execute:
- Place ASPxSiteMapControl within ASPxMenu.SubMenuTemplate;
- Specify the ASPxSiteMapControl.DataSource property. ASPxSiteMapControl and ASPxMenu should have different ASPxSiteMapDataSource;
- Handle the ASPxSiteMapControl.DataBinding event;
- Define the ASPxSiteMapDataSource.StartingNodeUrl property according to the parent menu node's NavigateUrl:
Goof example. But when I click at the any mainmenu ("SubCategoryA" for example) I got the error - 404 - File or directory not found.
Added By: Helen (DevExpress Support) at: 5/29/2014 5:24:16 AMHello Anton,
Thank you for the feedback. The cause of the problem is that the urls defined in the xml file do not refer to real pages. I've replaced them with dummy code that does not raise 404 error.
This example demonstrates how to dynamically create a report based upon the ASPxGridView control at runtime. This means that all filtering, sorting and grouping conditions selected in the grid are also applied in a report. To accomplish this task, it is necessary to create a report with all the necessary bands, bind it to a data source and adjust all the necessary options.You can use this approach if you need to display content of templated columns in your report or insert a report based on ASPxGridView to another report.

Dear support. I have been trying for several days now to export custom cell templates of a pivotgrid but with no luck. From my previous posts, I understand that the exporting of pivotgrid custom cells is not supported, nor are there any plans to support this in the future. This is a serious shortfall for us and could mean that we are just not able to use your controls if we are not able get the data out to the users.
I then came across this post which appears to be doing exactly what we need to do, although this is doing it against a ASPXGridView and not against a ASPXPivotGrid.
I have been trying to "translate" the C# code so that it instead works off of the ASPXPivotGrid but have not been able to.
Is there any chance that somebody there could provide the equivalent sample that will take a ASPXPivotGrid and create a report out of it which includes the templated cells? As an ideal example, if you are able to show how this code would work against your own templated example found here: http://demos.devexpress.com/aspxpivotgriddemos/Templates/CellTemplates.aspx
I have seen several posts now where users are requesting the ability to export templated cells from the pivotgrid, so I am sure any assistance/sample code you can provide along the same lines as what you have done here will be very useful for quite a few of us.
Thanks in advance

By default, the FilterControl's FilterCriteria property is updated only after the ApplyFilter method has been called, while the ActualFilterCriteria property does not send notifications when the user changes the filter.
This sample project shows how to force an unbound FilterControl to update its FilterCriteria property and bind another control or a view model to this property.
A grid containing a number of groups (master), each with a number of lines (detail) is a representation of an order which is grouped for readability. When a group has a greater number of lines then fits on the screen, a scrollbar is added to the detail-view and when there are multiple groups the master-view also gets a scrollbar. When the user scrolls through the grid, only the master-view is scrolled (unless a row is selected, then only the detail-view is scrolled) and it feels like the program is behaving oddly, as half the rows are skipped.
To achieve this goal, we need the GridControl to have a height equal to the height of all content placed in a master-view. So, the scrollbar does not appear in either the master-view or in the detail-view. To allow scrolling, we need to put our GridControl into a XtraScrollableControl and set the GridControl.Dock property to DockStyle.Top.
We created the MyGridControl class - a descendant of the GridControl. MyGridControl works with MyGridView views and includes the CalcGridHeight() method, which is called when the appearance of the Master-View is changed.
To put MyGridControl in the XtraScrollableContainer, use the MyGridControl.InitScrolling method at runtime. Use the MyGridControl.InitScrollingInLayout method to initialize scrolling in a LayoutControlItem.
Please note that if you want to change Bounds or Dock properties of MyGridControl at runtime, change similar properties of the MyGridControl.ScrollableContainer control.
The solution works great except that with that solution, since the XtraScrollableContainer contains the whole grid, we loose the header when we scroll so the user must scroll to the top to be able to sort, group, ...

This example provides a possible workaround for the Filtering - Support searching objects by a string through all the properties (or a set of properties) or by more complex criteria suggestion.
The Dennis.Search.Win module, shown in the example, provides API to create a non-persistent object that can be used to search by properties of a business class. Such a non-persistent search-object should implement the ISearchObject contract. By default, it's supported by the abstract and generic SearchObjectBase class in the module. Search-objects are shown in a Detail View with the help of the SearchObjectViewController. To compose a search criteria, a specific SearchObjectPropertyEditor is used (it contains the Search and Clear buttons).
An example use of the implemented module is illustrated in the WinSolution.Module.Win module. There is a ProductSearchObject class that is inherited from the base SearchObjectBase class. If necessary, you can create several search objects for one business class. In UI, all search objects will be listed in a drop-down list in the toolbar of a View of your business class. Download and run the attached example to see how this works in action.
(Take special note of the SearchObjectBase class implementation, because it asynchronously loads search results of a specific type from the data store into the Search Results nested List View.)

This example demonstrates how to check whether the user is logged in and display a login view when it is necessary during navigation.
It is necessary to perform the following steps to accomplish this task:
1. Add a new view and place a dxPopup in it.
2. Implement the required logic for this view in a corresponding view model.
3. Handle the HtmlApplication.initialized event. In this event handler, get the login view template using the HtmlApplication.getViewTemplate method and add the view to the view port. This will allow you to display its internal popup using options from its view model.
4. Bind the login view model to the view markup using Knockout.
5. Declare a global variable for determining when a user is logged in. In this example we set this option to false by default, and we will set it to true when a user is logged in. This variable can be accessed from any part of the application and we can change its value in the login view model.
6. Handle the HtmlApplication.navigating event. In this event handler, we can get a view info (see HtmlApplication.getViewTemplateInfo) for the navigated view and check user credentials if necessary. For this purpose, we added the secure option to those views that should not be displayed for unauthorized users. If the user unauthorized, we can call a method from the login view model to display dxPopup from the login view. Moreover, you can cancel navigation by setting the cancel parameter of the event handler to true.
