我在windows phone xaml页面中有网格视图，这个网格包含许多UI元素，如按钮，复选框和文本框。我想根据名称从网格中搜索特定的uielelement并获取该uielelement的值并设置一些新值。我如何从网格中获得与Visual Tree helper在代码后面的元素。

<Grid x:Name="ContentPanel" Grid.Row="1" Margin="12,0,12,0">
            <Grid.RowDefinitions>
                <RowDefinition Height="120" />

            </Border>
        </Grid>

我想匹配选项。让我们说左边一些图片被点击，它的边界改变了，一旦在右边点击哪个选项是匹配的，左边有一些选择或没有

获得特定的UIElemet从网格在Windows Phone与可视化树的帮助

你能告诉我你到底想从网格元素中得到什么，因为里面只有边框和图像。您可以通过这个泛型编码找到元素。(ContentPanel是你的网格名称)，你可以得到边界和图像和其他控件的名称和其他属性，以及下面的程序。

 foreach (var child in ContentPanel.Children)
        {
            if (child is Border)
            {
                var borderName = (child as Border).Name;
                // if you wana get the image inside border, then do this.
                var getBorderChlid = (item as Border).Child;
                if (getBorderChlid is Image)
                {
                    var getImgName = (getBorderChlid as Image).Name;
                }
            }
        }

如果这对你有帮助，那么很好，否则解释你的任务多一点，然后我将发送给你确切的代码InshaAllah
