    Adding Properties to a Custom Column
    In This Topic

    You may want to add properties to a column in order to set a specific behavior. Continuing with the hyperlink column created in the previous topics, in this topic you'll add a property called TargetName. This property allows the user to specify the name of the target window or frame where the page will open.

    Complete the following steps:
    Add the following code to create the TargetName property:

    Visual Basic
    Copy Code 
    Private _TargetName As String
Public Property TargetName() As String
    Get
        Return _TargetName
    End Get
    Set(ByVal value As String)
        _TargetName = value
    End Set
End Property
    C#
    Copy Code 
    public string TargetName { get; set; }

     


    2.   Once the property is created you'll propagate this to the hyperlink in the BindCellContent method:

    Visual Basic
    Copy Code 
    Public Overloads Overrides Sub BindCellContent(ByVal cellContent As FrameworkElement, ByVal row As DataGridRow)
    Dim hyperlink = DirectCast(cellContent, HyperlinkButton)
    If Binding IsNot Nothing Then
        Dim newBinding As Binding = CopyBinding(Binding)
        newBinding.Source = row.DataItem
        hyperlink.SetBinding(HyperlinkButton.NavigateUriProperty, newBinding)
    End If
    hyperlink.HorizontalAlignment = HorizontalAlignment
    hyperlink.VerticalAlignment = VerticalAlignment
    hyperlink.TargetName = TargetName
End Sub

     

    C#
    Copy Code 
    public override void BindCellContent(FrameworkElement cellContent, DataGridRow row)
{
    var hyperlink = (HyperlinkButton)cellContent;
    if (Binding != null)
    {
        Binding newBinding = CopyBinding(Binding);
        newBinding.Source = row.DataItem;
        hyperlink.SetBinding(HyperlinkButton.NavigateUriProperty, newBinding);
    }
    hyperlink.HorizontalAlignment = HorizontalAlignment;
    hyperlink.VerticalAlignment = VerticalAlignment;
    hyperlink.TargetName = TargetName;
}


    Tips

    You may find the following tips helpful when adding properties to a custom column:

    • Provide a constructor that takes PropertyInfo as parameter calling base(property) in order to automatically set the Binding, SortMemberPath, FilterMemberPath and Header properties as well as properties set using custom attributes. Currently supported attributes include: DisplayAttribute (AutoGenerateFilter, Name, GroupName, Order), DisplayFormatAttribute, and EditableAttribute.

     

    C#
    Copy Code 
    public DataGridHyperlinkColumn(PropertyInfo property) : base(property)
