  • ASP.NET Query Builder (Coming soon in v15.2)

    Good news, there is a new ASP.NET control, in the v15.2 release, that allows your end-users to visually build queries! And you can then apply those queries on existing DevExpress controls like the ASP.NET GridView.

    Here's a screenshot of the new Query Builder control's UI:

    The Query Builder functionality was first introduced as part of our XtraReports' new web report designer. Many of you have requested this as a separate/independent control (and we agree).

    Your power users will love this feature as it provides them a visual way to create their own queries.

    Query Builder (Preview)

    We're introducing the new DevExpress ASP.NET Query Builder control as a preview version in the v15.2 release because it's we're still perfecting it. However, the new ASP.NET Query Builder control has enough of a feature set that we'd love for you to test drive it and give us your feedback.

    Features

    The DevExpress ASP.NET Query Builder allows your end-users to visually construct SQL queries and return a string containing a SELECT statement. So it contains great features like:

    • The database schema is automatically obtained and displayed within the QueryBuilder's UI.
    • Ability to visually edit 'WHERE', 'ORDER BY' and 'GROUP BY' query clauses.
    • Relationships between tables are automatically resolved based on foreign keys.
    • Query results preview.

  • ASP.NET HTML Editor - Source Code Editing and more (Coming soon in v15.2)

    There's a great new feature for the DevExpress ASP.NET HTML Editor in v15.2 release: Source Code Editing features like Visual Studio.

    To see it in action, check out this short video:

    New Features

    Here's a list of all the new features for the DevExpress ASP.NET HTML Editor in the v15.2 release:

    • Syntax highlighting
    • Auto completion
    • Indents
    • Auto closing tags
    • Highlight active line & matching tags
    • Find and Replace functionality
    • Edit whole document
    • Contextual tabs (via Ribbon control)

    Find and Replace

    Your end-users can now easily locate and modify text data within both the Design and HTML views of the DevExpress ASP.NET HTML Editor. We've added a combination of a Search Panel and the Find and Replace Dialog to enable slick new functionality.

    To show the Search Panel, use the Ctrl+F shortcut. The Find and Replace Dialog can be invoked using a specific toolbar button or through the Search Panel's dropdown button.

    When you type a search string, the editor's search engine automatically searches the content and highlights potential matches making them navigatable. In the Find and Replace Dialog, the search results are displayed as clickable list items that you can navigate as well.

    Edit Full HTML Document

    The DevExpress ASP.NET HTML Editor now provides the ability to edit the entire HTML document, including the content of the following tags:

    Now your end-users can create and edit the entire web pages using the DevExpress ASP.NET HTML Editor.

    Ribbon Improvements

    New features of the ASPxRibbon control (contextual tabs) are also available in the DevExpress ASP.NET HTML Editor to improve the functionality of its built-in ribbon navigation.

  • ASP.NET Spreadsheet - Frozen Columns/Rows, Data Validation and More (Coming soon in v15.2)

    Check out these great new features coming to the powerful DevExpress ASP.NET Spreadsheet in the next release, v15.2.

    These features are available for both the ASP.NET WebForms and MVC versions of the Spreadsheet. The new features include:

    Frozen Panes (Rows and Columns)

    With an Excel inspired Freeze Panes feature, end-users can lock specific rows or columns in one area to keep this area of a worksheet visible while scrolling the worksheet content vertically or horizontally.

    DevExpress ASP.NET Spreadsheet - Frozen Columns & Rows

    Data Validation

    An Excel inspired data validation feature helps prevent end-users from entering invalid data into worksheet cells. This feature allows you to definie restrictions and provide notifications on what data can or should be entered in a cell:

    DevExpress ASP.NET Spreadsheet - Data Validation

    Because it is difficult to see what validation is added to a cell, in the above image, we've added the green callout box images to highlight the validation in the spreadsheet cells. Those boxes are not part of the spreadspeet.

    Table Sorting and Filtering

    End-users can now use the Excel inspired AutoFilter feature to filter data by columns and to easily display only rows that meet specific conditions. Three filter types are available (depending upon the column data types): Text, Number, and Date Filters. In addition, the Filter by Values option can be used which allows you to select from column unique values.

    DevExpress ASP.NET Spreadsheet - Sorting & AutoFilter

    Formula Bar

    An Excel-like formula bar shows the contents of the current cell and allows creating and viewing formulas. To start creating a formula, click the mouse cursor in the formula bar and enter an equal sign (=).

    DevExpress ASP.NET Spreadsheet - Formulas

    Formula AutoComplete

    The Formula AutoComplete feature makes it easier to create and edit formulas and minimizes typing and syntax errors. After typing an equal sign (=) and beginning letters into a cell, a dynamic drop-down list of valid functions that match the letters is displayed below the cell.

    Document Autosave

    The Autosave feature helps reduce the risk of data loss by saving an opened document automatically at predefined but customizable intervals. And you can programmatically handle:

    • autosave operations: like saving to some other custom storage
    • resolve multi-user conflicts (should any arise)

    Work Session Hibernation

    This feature helps you to save memory (RAM). When enabled, the 'work session hibernation' will automatically free server memory by hibernating inactive open documents in the spreadsheet.

    If this feature is enabled, open documents which where idle for a certain time can be released from the server memory and saved to the server file system at a specific path. The hibernation settings (such as a session timeout, server directory) are available through an API exposed by the server DocumentManager object.

    This hibernation feature helps if the server fails because when the server is restarted, the spreadsheet control will load the hibernated document and allow you to continue working.

    Extended Page Setup Functionality

    A new Page Setup dialog helps end-users prepare the document for printing. The dialog helps setup several print-related settings (such as document orientation, paper size, page margins, page order, etc.) and provides the capability to specify header and footer text too.

    DevExpress ASP.NET Spreadsheet - Page Setup

    Ribbon Improvements

    The built-in ribbon is improved by employing the ASPxRibbon control's newly implemented features, such as contextual tabs and one-line mode. Thus, the 'Design' ribbon context tab help with working with tables in a worksheet. One-line ribbon can be used to make navigation more compact within a control and make more room for document editing.

  • ASP.NET Grid View - Data Range Filter, Adaptivity and More (Coming soon in v15.2)

    In the v15.2 release, we've added powerful new capability and features to the DevExpress ASP.NET Grid View control. And I'm happy to announce that these features are available for both ASP.NET WebForms and MVC versions of our GridView!

    Responsive & Adaptive!

    This release ships with new options that make your web grid application responsive. Our ASP.NET GridView can now automatically adapt its UI based on the screen size (resize UI elements, hide cells of small columns, switch from a table to a card layout on smaller screens, etc.).

    Date Range Header Filter

    Two new representation modes inspired by Microsoft Windows Explorer are now available for the GridView's date column header filter dropdown. You can define a date range using a calendar or date editors. In both modes, the filter dropdown displays a customizable list of check boxes that allow you to select common date intervals: 'Last week', 'Last month', 'Last year', etc.

    Conditional Formatting

    With this release, our ASP.NET GridView supports Microsoft Excel inspired conditional formatting of individual cells. Your end-users can now highlight critical information, compare data, visualize trends by using data bars, color scales or icons. Format conditions applied to data cells can also be exported to PDF, RTF, XLS and XLSX.

    Truncated Cell Values

    Our ASP.NET GridView can now automatically truncate cell values if they don't fit into cell width. To indicate that the text is clipped, the grid displays an ellipsis ('...'). Point the mouse cursor over an ellipsis to display a tooltip with the full text.

    DevExpress ASP.NET GridView - Text Ellipsis

    Improved EditForm Layout Designer

    This release ships with the improved EditForm Designer available at design time. Its new features include:

    • Ability to move layout items via drag and drop.
    • Ability to assign a nested control to an item via a context menu.
