如果您按下ADG上的鍵盤按鍵，則所選行將移至第一行，從而找到第一列單元格的文本以您剛按下的字符開頭。有誰知道是否有財產將此行爲關閉？按AdvancedDataGrid上的鍵選擇行：如何禁用？

這裏有一個簡單的代碼片段，顯示這一點，如果你想使用一些代碼來打......

好吧，我通過在第一列中的每個字符串前添加空格（調整與該列關聯的LabelFunction函數）來破解解決方案 - 非常可怕，但它似乎有訣竅。如果有一種明顯的方法可以解決這種行爲，我們仍然會很樂意聽到。 – 2010-11-02 18:48:47

感謝您提供完整的示例。這對於尋找解決方案總是非常有幫助的。我在下面張貼了我的。 – 2010-11-03 08:32:59

爲了禁用此行爲，您必須使用擴展AdvancedDataGrid的自定義組件。在此組件中，您可以覆蓋方法findKey()，該方法負責選擇以按鍵開頭的第一行。

public class CustomAdvancedDataGrid extends AdvancedDataGrid 
{ 
    public function CustomAdvancedDataGrid() 
    { 
     super(); 
    } 

    protected override function findKey(eventCode:int):Boolean 
    { 
     return false; 
    } 
}
