This example demonstrates how to use the SpreadsheetControl API to programmatically manage spreadsheet documents, without the need for Microsoft Excel to be installed.

In particular, this sample introduces API properties and methods used to perform the following operations:

- Manage worksheets (activate, create, delete, rename, copy, adjust worksheet view, etc.)

- Manipulate rows and columns (insert, delete, copy rows and columns, adjust row height and column width, etc.)

- Manipulate cells and cell ranges (set cell values, add hyperlinks to cells, copy and merge cells), create, edit and copy cell comments

- Create formulas (use various functions and cell references in formulas, use names in formulas, create shared and array formulas, etc.)

- Format cells (set cell font, colors, alignment, borders, number format, etc.)

- Export the workbook to PDF

- Print the workbook

Spreadsheet - How to perform a request to the server using jQuery.ajax to get cell values

November 30, 2015, 4:37 am
$
0
0

It is necessary to update the Spreadsheet state before sending a request to the server. Data for jQuery.ajax is prepared manually, so we cannot automatically trigger editor updates.

There are two possible solutions:

1) Use Ajax.BeginForm instead of a custom $.ajax request. So, the required information will be prepared automatically before the form is posted.

2) Call our non-documented OnPost method that collects all required information for the Spreadsheet. Please note that the name or implementation of this method may be changed in the future without any notification.

 

[JScript]
function OnClick(){   var url = "Home/ValidateSpreadsheet/";    Spreadsheet.OnPost();    $.ajax({        type: "POST",        url: url,        data: $('form').serialize(),        success: function(data){            myLabel.SetText(data);       }   });}

How to prevent a DetailView from being shown when a User double clicks or presses the Enter key on a record in a ListView

December 31, 2000, 4:00 pm
$
0
0

Scenario

For certain data forms, a developer needs to limit end-users to editing only through the ListView, i.e. without invoking a separate DetailView.  This is usually done by activating the inline editing and MasterDetailMode = ListViewAndDetailView features as described at eXpressApp Framework > Concepts > UI Construction > Views > List View Edit Modes. More real user scenarios are described in this Support Center thread.


For more convenience and flexibility, the following Model Editor extensions are implemented in the example to control this behavior:
 - The DefaultShowDetailViewFromListView  attribute at the Views node level allows you to control this functionality globally per application via the Model Editor;
 - The ShowDetailView attribute at the Views | ListView node level allows you to customize only certain List Views via the Model Editor;




Steps to implement

1. Copy the WinWebSolution.Module\ShowDetailViewFromListViewController.xx file into the YourSolutionName.Module project and rebuild it.

Note: The process of opening a DetailView by double clicking/pressing the Enter key on a record selected in a ListView is managed by the standard DevExpress.ExpressApp.SystemModule.ListViewProcessCurrentObjectController class and its ProcessCurrentObjectAction in particular. So, we can disable this Action to accomplish our task. The approaches from the eXpressApp Framework > Concepts > Application Model > Extend and Customize the Application Model in Code,  eXpressApp Framework > Concepts > Application Model > Access the Application Model in Code and ActionBase.Enabled Property articles will be used here.

2. For testing purposes, invoke the Model Editor and set the DefaultShowDetailViewFromListView or ShowDetailView properties for the Views or Views | YourObjetType_ListView nodes to False and run the test app to see that a required ListView no longer opens a DetailView in the aforementioned scenario.

IMPORTANT NOTES
This article covers only the case when a DetailView is shown from the ListView after a User double clicks/presses the enter key on a record. Other scenarios should be handled separately by extending the code of this controller. For example, if you do not want to show a DetailView after a new object is created via the New Action, you can handle the NewObjectViewController.ObjectCreating event and set its ObjectCreatingEventArgs.ShowDetailView property to False. However, this is outside the purpose of this article.

This example demonstrates how to catch a double click on a column's header, and show a text editor which allows an end-user to rename the column.

Question Comments
Added By: jtrebino at: 8/8/2012 7:57:50 AM    

I fail to see where in this code example the mouse double click is captured so that the user can then perform some task or have the code actually change the column's caption.

Added By: Dave VanderWekke (Automated Wireless Environments) at: 2/24/2014 12:18:04 PM    

This works great for renaming however if you save the layout the new Caption is not saved in the layout. How can this be achieved?

OBSOLETE - How to validate objects when navigating between records and the list view is in the ListViewAndDetailView mode

=================================
This example is now obsolete. Instead, set the ModificationsController.ModificationsHandlingMode property to AutoCommit.
=================================

By default, XAF objects are not immediately validated when moving between records in the list or detail view and when using the navigation buttons or selecting records in the grid. This example demonstrates how to work around this design and prompt a user once he is about to leave the edit mode and go to another record.

Is there a WPF (instead of winforms) solution to this also?

Added By: avian_johnson at: 12/4/2015 2:21:43 AM    

Hello,

Thanks for this auto scroll code.
It works good for right, left and bottom drag. But there is a wrong condition for top drag in AutoScrollHelper.cs.
this is the condition which not worked for me.
  fScrollInfo.GoUp = (pt.Y < rect.Top + ThresholdInner) && (pt.Y > rect.Top - ThresholdOutter);

I have corrrected it & now it is working for me.
Modified Condition :
    fScrollInfo.GoUp = (pt.Y > rect.Top - ThresholdInner) && (pt.Y < rect.Top + ThresholdOutter);

Thank You

ASPxGridView in Endless Paging Mode with the Total summary item - How to avoid refreshing the whole ASPxGridView control after editing

December 4, 2015, 12:59 am
$
0
0

In this example, the following scenario is illustrated:
1) ASPxGridView operates in Endless paging mode.
2) ASPxGridView contains the total summary item.
3) An ASPxGridView row is updated/deleted/inserted on the N page (for example, the AllowFocusedRow property is set to true and the edit row is focused).
4) After updating, ASPxGridView needs to update the total summary item and get completely refreshed.
5) Due to refreshing ASPxGridView in Endless mode, the control loses all uploaded pages and the edit row loses focus (the current page is reset to the first page and focus is set to the first row).
This example demonstrates how to avoid this scenario. Set the Visible property of the total summary item to false - in this case, ASPxGridView isn't refreshed after the update/delete/insert operation. Then, create a footer template, and use the GetTotalSummaryValue and GetTotalFooterDisplayText methods to fill the template with a required value.
