Filter Silverlight DataGrid data programmatically

by viblend 10. July 2012 16:22
In order to achieve this, you need to follow the steps below:
 
1. Create DataGrid’s Rows, Columns and fill it with sample data. 
 
C#

for (int i = 0; i < 20; i++)
{
    this.dataGrid1.ColumnsHierarchy.Items.Add("Column " + i);
    this.dataGrid1.RowsHierarchy.Items.Add("Row " + i);
}

this.dataGrid1.AllowContextMenuFiltering = true;
this.dataGrid1.AllowContextMenuSorting = true;
Random random = new Random();

for (int i = 0; i < 20; i++)
{
    HierarchyItem row = this.dataGrid1.RowsHierarchy.Items[i];
    for (int j = 0; j < 20; j++)
    {
        HierarchyItem column = this.dataGrid1.ColumnsHierarchy.Items[j];
        column.AllowFiltering = true;
        this.dataGrid1.CellsArea.SetCellValue(row, column, (double)i);
    }
}

this.dataGrid1.ColumnsHierarchy.AutoResize(AutoResizeMode.FIT_ALL);
this.dataGrid1.RowsHierarchy.AutoResize(AutoResizeMode.FIT_ALL);

VB .NET

For i As Integer = 0 To 19
    Me.dataGrid1.ColumnsHierarchy.Items.Add("Column " & i)
    Me.dataGrid1.RowsHierarchy.Items.Add("Row " & i)
Next i

Me.dataGrid1.AllowContextMenuFiltering = True
Me.dataGrid1.AllowContextMenuSorting = True
Dim random As New Random()

For i As Integer = 0 To 19
    Dim row As HierarchyItem = Me.dataGrid1.RowsHierarchy.Items(i)
    For j As Integer = 0 To 19
        Dim column As HierarchyItem = Me.dataGrid1.ColumnsHierarchy.Items(j)
        column.AllowFiltering = True
        Me.dataGrid1.CellsArea.SetCellValue(row, column, CDbl(i))
    Next j
Next i

Me.dataGrid1.ColumnsHierarchy.AutoResize(AutoResizeMode.FIT_ALL)
Me.dataGrid1.RowsHierarchy.AutoResize(AutoResizeMode.FIT_ALL)
 
2. Create a new NumericFilter and set its ComparisonOperator and Value properties
 
C#

NumericFilter filter = new NumericFilter();
filter.ComparisonOperator = NumericComparisonOperator.GREATER_THAN;
filter.Value = 5;
FilterGroup<double?> filterGroup = new FilterGroup<double?>();
filterGroup.AddFilter(FilterOperator.AND, filter);

VB .NET

Dim filter As New NumericFilter()
filter.ComparisonOperator = NumericComparisonOperator.GREATER_THAN
filter.Value = 5
Dim filterGroup As FilterGroup(Of Nullable(Of Double)) = New FilterGroup(Of Nullable(Of Double))()
filterGroup.AddFilter(FilterOperator.AND, filter)

3. Create a new HierarchyItemFilter object and add the FilterGroup to it. 
 
C#

HierarchyItemFilter itemFilter = new HierarchyItemFilter();
itemFilter.Item = this.dataGrid1.ColumnsHierarchy.Items[0];
itemFilter.Filter = filterGroup;

VB .NET

Dim itemFilter As New HierarchyItemFilter()
itemFilter.Item = Me.dataGrid1.ColumnsHierarchy.
itemFilter.Filter = filterGroup
 
4. Finally, add the HierarchyItemFilter instance to the Filters collection of the DataGrid’s RowsHierarchy. 
 
C#

this.dataGrid1.RowsHierarchy.Filters.Add(itemFilter);

VB .NET

Me.dataGrid1.RowsHierarchy.Filters.Add(itemFilter)
 

Silverlight TreeView with Radio Button

by viblend 16. February 2012 21:15
This post will show you how to add radio buttons to the TreeView items.

In order to display radio buttons in the VIBlend TreeView for Silverlight, you need to set the EnableCheckboxes property to true and also the ListItemType of each TreeViewItem to "RadioButton".

For example:

<viblend:TreeView EnableCheckBoxes="True" Width="280" Height="300" x:Name="TreeView">
    <viblend:TreeViewItem ListItemType="RadioButton" DisplayValue="VIBlend" Value="VIBlend" ImageSource="/Images/user.png">
        <viblend:TreeViewItem ListItemType="RadioButton" DisplayValue="Contacts" Value="Contacts" ImageSource="/Images/contacts.png"/>
        <viblend:TreeViewItem ListItemType="RadioButton" DisplayValue="Desktop" Value="Desktop" ImageSource="/Images/desktop.png"/>
        <viblend:TreeViewItem ListItemType="RadioButton" DisplayValue="Documents" Value="Documents" ImageSource="/Images/documents.png"/>
        <viblend:TreeViewItem ListItemType="RadioButton" DisplayValue="Downloads" Value="Downloads" ImageSource="/Images/folder.png"/>
        <viblend:TreeViewItem ListItemType="RadioButton" DisplayValue="Favorites" Value="Favorites" ImageSource="/Images/favorites.png"/>
        <viblend:TreeViewItem ListItemType="RadioButton" DisplayValue="Music" Value="Music" ImageSource="/Images/music.png"/>
        <viblend:TreeViewItem ListItemType="RadioButton" DisplayValue="Pictures" Value="Pictures" ImageSource="/Images/Pictures.png"/>
        <viblend:TreeViewItem ListItemType="RadioButton" DisplayValue="Searches" Value="Searches" ImageSource="/Images/searches.png"/>
        <viblend:TreeViewItem ListItemType="RadioButton" DisplayValue="Videos" Value="Videos" ImageSource="/Images/videos.png"/>
    </viblend:TreeViewItem>
    <viblend:TreeViewItem ListItemType="RadioButton" DisplayValue="Inbox" Value="Inbox" ImageSource="/Images/folder.png"/>
</viblend:TreeView>

Here's the resulting TreeView:

New ChildWindow control coming to VIBlend Silverlight Controls v5.0

by viblend 21. April 2011 19:38

In the next version of VIBlend Controls for Silverlight, we will introduce a new control - Silverlight ChildWindow. The ChildWindow control allows you to direct a user’s attention to a particular activity in your application such as entering data or viewing information. This new control resembles a standard Window and can be displayed in a modal or non-modal popup. When the control is displayed in a modal mode, the interaction with the underlying user interface is blocked.

Built-In Features:

  • Animated Open and Close Effects - the window is opened and closed with a smooth animation.
  • Resizing Support - users can choose to drag edges to resize the window.
  • Modal Mode - when the window is opened in a modal mode, the end-users cannot access any part of the interface outside of the dialog.
  • Non-Modal Mode - this mode enables the end-users to access the application's user interface.
  • Startup Position - you can choose the window's startup position. By default, the window is started at the application's middle-center.
  • Minimized and Maximized states - the window can be maximized or minimized similar to the standard Windows.
  • Application Boundaries Detection - end-users cannot drag or resize the window outside of the application's boundaries.
