[Solved] Auto Column Widths on Bold Data

[Carl Rippon]

Auto column widths appears to be a little out if the content is bold. The attached screen shot shows what I am getting (left hand side) and what I would like (right hand side). You can see that the automatic width should have been a little wider to accommodate the time.

To recreate, create a new silverlight project, copy the code below into the code behind of MainPage and run it up. You should see that the time part has been chopped off.

Is this expected behaviour? Is there a work around?

Partial Public Class MainPage
    Inherits UserControl

    Public Sub New()
        InitializeComponent()

        Dim RadGridView1 As New Telerik.Windows.Controls.RadGridView
        RadGridView1.AutoGenerateColumns = False
        RadGridView1.Columns.Add(New GridViewDataColumn With {.DataMemberBinding = New Binding("Date"), .Header = "Date", .TextWrapping = TextWrapping.Wrap})
        Dim data As New List(Of DateTime)
        data.Add(Date.Now)
        data.Add(Date.Now)
        data.Add(Date.Now)
        RadGridView1.ItemsSource = data
        AddHandler RadGridView1.RowLoaded, Sub(s, e)
                                               e.row.FontWeight = FontWeights.Bold
                                           End Sub
        LayoutRoot.Children.Add(RadGridView1)
    End Sub


End Class

Hi Carl Rippon,

When row is loaded  the column widths are already calculated  then you set  the text to be bold  - this is the cause of the trouble.

The solution :

Instead of setting the bold font inside the RowLoaded event , use the standard Silverlight approach :

Please use Style with Setter for the font . This way you will let the framework set the font in the right moment and measurement will be correct .

Kind regards,

Thanks. I eventually got this working using the RowStyleSelector property of the grid. The style selectors example in the demos was very useful.
