我在我的Silverlight應用程序中使用NumericUpDown控件。使用Tab在Silverlight頁面中導航控件時遇到問題。如何設置TextBox內的NumericUpDown控件的TabIndex Silverlight
案例1：當我的控制焦點在NumericUpDown上，我使用了向下按鍵時，我的值在NumericUpDown控件中遞增和遞減。當按下Tab鍵焦點移至下控制誰的tabIndex是+1
案例2：當我點擊NumericUpDown控件，所以我NumericUpDownControl得到關注，因爲我點擊它，當我在它通過鍵盤，然後按回車值標籤ID不會移動到下一個控件。 （因爲它在第一種情況下移動）
我發現當我點擊NumericUpDown控件，然後按下案例2中的選項卡：在控件的按鍵事件中，我得到原始源文本框。
** private void Control_KeyDown(object sender, KeyEventArgs e)
{
if (e.OriginalSource as Control != null
&& e.Key == Key.Tab)
{
Int32 index = (e.OriginalSource as Control).TabIndex;
if (index == Int32.MaxValue) index = index1; //??//
if (Keyboard.Modifiers == ModifierKeys.None)
{
}
else if (Keyboard.Modifiers == ModifierKeys.Shift)
{
}
}
}
**
在案例1：我NumericUpDown控件作爲原始來源 在案例2中：我得到了TextBox控件作爲原始來源
在那裏我有一組的TabIndex NumericUpDown控件，因爲我沒有得到TextBox的TabIndex屬性，我得到了上述問題。
那麼如何在NumericUpDown控件的TextBox上設置TabIndex。

**我想從<inputToolkit:ButtonSpinner></inputToolkit:ButtonSpinner>文本式T設置文本框運行時的abIndex屬性。
我該怎麼做。**
我設置「<文本框X：名稱= 」文本「 樣式= 」{StaticResource的TextBoxStyle}「 了borderThickness =」 0 「FontFamily =」{TemplateBinding FontFamily}「TabIndex =」{TemplateBinding TabIndex} FontSize =「{TemplateBinding FontSize}」FontStretch =「{TemplateBinding FontStretch}」FontWeight =「{TemplateBinding FontWeight}」Foreground = 「{TemplateBinding Foreground}」MinWidth =「50」Width =「Auto」AcceptsReturn =「False」Text =「{TemplateBinding Value}」TextAlignment =「Left」TextWrapping =「NoWrap」/>'我得到父屬性自定義模板控制。 – PramodChoudhari
