在ComboBoxEdit中選擇幾個項目

Question

我使用ComboBoxEdit（DevExpress）和CheckedComboBoxStyle設置過濾器。我如何通過代碼選擇一些項目？

Answer 1

請必需項添加到ComboBoxEdit.SelectedItems收集

標記：

xmlns:dxe="http://schemas.devexpress.com/winfx/2008/xaml/editors" 
... 
<dxe:ComboBoxEdit x:Name="cbEdit" IsTextEditable="False"> 
    <dxe:ComboBoxEdit.StyleSettings> 
     <dxe:CheckedComboBoxStyleSettings /> 
    </dxe:ComboBoxEdit.StyleSettings> 
</dxe:ComboBoxEdit> 

後面的代碼：

string[] platforms = new string[] { "Win98", "Win2000", "WinNT", "WinXP", "Vista", "Win7" }; 
cbEdit.ItemsSource = platforms; 
cbEdit.SelectedItems.Add(platforms[4]); 
cbEdit.SelectedItems.Add(platforms[5]); 

Answer 2

根據文檔：

http://documentation.devexpress.com/#WindowsForms/clsDevExpressXtraEditorsCheckedComboBoxEdittopic

要編輯一組布爾選項，添加相應的項目到RepositoryItemCheckedComboBoxEdit.Items集合。每個項目由一個CheckedListBoxItem對象表示，提供下列選項：

ListBoxItem.Value - represents the item's value. Typically, this property must specify a unique string. For check items, it's also possible to specify the display text via the CheckedListBoxItem.Description property. 
CheckedListBoxItem.CheckState - represents the item's check state (checked or unchecked). The indeterminate state is not supported. 
CheckedListBoxItem.Enabled - specifies whether the item's state can be changed by an end-user.
