VIBlend WinForms Controls ver. 4.6 – Released

by viblend 22. April 2010 09:17

We are happy to announce the release of the latest version of VIBlend Controls for WinForms.

VIBlend Windows Forms Controls 4.6.0 - Release Notes

1. Added support for Visual Studio 2010
2. Moved all design time classes of our controls to separate assembly
3. DataGridView changes

In this version we extended the HierarhcyItem mouse click events. Previously, the grid was raising only the ItemClick and ItemDoubleClick events.

These two events are replaced by the following set of events:

 - HierarchyItemMouseUp
 - HierarchyItemMouseDown
 - HierarchyItemMouseClick
 - HierarchyItemMouseDoubleClick

We also added several improvements in the in-place cell editors' infrastructure. Specifically we added the following activation and deactivation events:

 - Click on selected cell (MOUSE_CLICK_SELECTED_CELL)
 - Enter key activation (KEY_PRESS_ENTER
 - Esc key deactivation (KEY_PRESS_ESC)

The default activation and deactivation flags for the built-in cell editors where modified to use the new activation events.

Please, note that these are breaking changes. If you are using an earlier version of VIBlend Controls for Windows Forms you will have to make minor changes to your code.

New in version 4.6 are the HierarchyItems and Cells selection changed events:
 - DataGridView.HierarchyItemSelectionChanged
 - DataGridView.CellSelectionChanged

Pivot Grid - Traditional vs Compact style layout

by viblend 18. April 2010 05:36

VIBlend DataGridView for WinForms offers multiple unique features that cannot be found in other Windows Forms data grid controls. These include multi-level hierarchies on rows and columns, rows grouping, pivot tables, and built-in OLAP capabilities. One of the main drawbacks of the traditional OLAP style rows layout is that it takes a lot of screen space. 

 

This could be improved by using the compact style layout. In this mode the rows of the pivot table are rendered in a tree-like structure.

 


Switching from default to compact style rendering is very easy. It requires setting the value of RowsHierarchy.CompactStyleRendering property to true:

C#
grid.RowsHierarchy.CompactStyleRenderingEnabled = true;
grid.RowsHierarchy.AutoResize();
grid.Invalidate();

VB .Net
grid.RowsHierarchy.CompactStyleRenderingEnabled = True
grid.RowsHierarchy.AutoResize()
grid.Invalidate()
 

You can switch between traditional and compact style rendering at runtime. The feature is also availalbe in VIBlend DataGrid for Silverlight.

Visual Studio 2010 and .Net Framework 4.0

by viblend 12. April 2010 03:22

VIBlend will fully support the .NET4 Client Profile in the next version of VIBlend Controls for WinForms which is expected in the middle of May. We will create a new VIBlend.WinForms.Controls.Design assembly and will move all the design time classes of our controls into it. The change is needed because the client profile does not include the standard design time classes and we need to remove the reference to the System.Design namespace in our present assemblies.

The upcoming release of the VIBlend Controls for Silverlight, which is due in May, will incorporate a full support for Visual Studio 2010. We will also have a new build for Silverlight 4 and our product will benefit from the new features in the latest platform’s edition. In addition, the new release will be shipped with three new themes for all of our controls and performance optimizations in the VIBlend OLAP Grid for Silverlight.

Using VIBlend DataGridView for WinForms in a WPF Application

by viblend 3. April 2010 21:56

In this blog post we will show you how to use the VIBlend DataGridView for WinForms in a WPF application.

The following code example creates a WinForms DataGrid control with Office2010Black theme in a WPF application. This example uses a WindowsFormsHost element to place the DataGrid control within the main window’s root  element. The WindowsFormsHost element could be found in the WindowsFormsIntegration.dll.

[xaml]

  <Window x:Class="HostWinFormsControlInWPF.Window1"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:viblend="clr-namespace:VIBlend.WinForms.DataGridView;assembly=VIBlendGrid"
        Title="Window1" Height="300" Width="300">
    <Grid>
        <WindowsFormsHost>
            <viblend:vDataGridView x:Name="VIBlendDataGrid" VIBlendTheme="OFFICE2010BLACK"/>               
        </WindowsFormsHost>
    </Grid>
</Window>

In order to bind the data grid, you need to do the following:  Click on the Data menu item in your Visual Studio, then select the “Add new DataSource” item.  Browse to the Nwind.mdb which ships with the WinForms controls installation, choose the Employees table and click finish. In the code behind, after the InitializeComponent call or in the Load event handler , bind the data grid to the Employees table.

            NwindDataSet dataSet = new NwindDataSet();
            EmployeesTableAdapter adapter = new EmployeesTableAdapter();
            adapter.Fill(dataSet.Employees);
            this.VIBlendDataGrid.DataSource = dataSet.Employees.DefaultView;
            this.VIBlendDataGrid.DataBind();

Here is the result:
