Formatting Items

Since RadFontDropDownList internally uses a RadListView in DetailsView, it is possible to customize each cell element, using the CellFormatting event.

You can access the hosted RadListView control by the RadFontDropDownList.FontListView property and subscribe to its CellFormatting event in order to customize cell elements:

Formatting the cell elements

private void FontListView_CellFormatting(object sender, Telerik.WinControls.UI.ListViewCellFormattingEventArgs e)
{
    DetailListViewDataCellElement cell = e.CellElement as DetailListViewDataCellElement;
    if (cell == null)
    {
        return;
    }
    if (e.CellElement.Data.Name == "Preview" && e.CellElement.Text == "Aharoni")
    {
        e.CellElement.BackColor = Color.Yellow;
        e.CellElement.ForeColor = Color.Red;
        e.CellElement.GradientStyle = Telerik.WinControls.GradientStyles.Solid;
    }
    else if (cell.Row.Selected)
    {
        e.CellElement.BackColor = Color.Aqua;
        e.CellElement.ForeColor = Color.Black;
        e.CellElement.GradientStyle = Telerik.WinControls.GradientStyles.Solid;
    }
    else
    {
        e.CellElement.ResetValue(LightVisualElement.BackColorProperty, Telerik.WinControls.ValueResetFlags.Local);
        e.CellElement.ResetValue(LightVisualElement.ForeColorProperty, Telerik.WinControls.ValueResetFlags.Local);
        e.CellElement.ResetValue(LightVisualElement.GradientStyleProperty, Telerik.WinControls.ValueResetFlags.Local);
    }
}

Private Sub FontListView_CellFormatting(sender As Object, e As UI.ListViewCellFormattingEventArgs)
    Dim cell As DetailListViewDataCellElement = TryCast(e.CellElement, DetailListViewDataCellElement)
    If cell Is Nothing Then
        Return
    End If
    If e.CellElement.Data.Name = "Preview" AndAlso e.CellElement.Text = "Aharoni" Then
        e.CellElement.BackColor = Color.Yellow
        e.CellElement.ForeColor = Color.Red
        e.CellElement.GradientStyle = Telerik.WinControls.GradientStyles.Solid
    ElseIf cell.Row.Selected Then
        e.CellElement.BackColor = Color.Aqua
        e.CellElement.ForeColor = Color.Black
        e.CellElement.GradientStyle = Telerik.WinControls.GradientStyles.Solid
    Else
        e.CellElement.ResetValue(LightVisualElement.BackColorProperty, Telerik.WinControls.ValueResetFlags.Local)
        e.CellElement.ResetValue(LightVisualElement.ForeColorProperty, Telerik.WinControls.ValueResetFlags.Local)
        e.CellElement.ResetValue(LightVisualElement.GradientStyleProperty, Telerik.WinControls.ValueResetFlags.Local)
    End If
End Sub
