绑定到Linq查询时获取数据网格选择 [英] Getting datagrid selection when bound to Linq Query

问题描述

我有一个绑定到Linq查询的WPF数据网格.第一列是表中的ID.当用户单击数据网格时，我需要能够获取该ID并在程序中的其他表单上进行进一步搜索.我已经在Google上进行了数小时的梳理，并取得了一些进展，但这与我使用Windows窗体和数据集的方式有所不同.疯狂的事情是，如果我在Datagrid的click事件中做这样的事情.....

var mySelection = dgSearch.SelectedItem;

我可以看到整个信息行.但是对于我的一生，我无法遍历这些数据.我认为这是一个iList，但似乎无法将这些数据分解为元素.

I have a WPF datagrid bound to a Linq query. The first column is the id from the table. When a user clicks on the datagrid I need to be able to take that ID and search further on a different form in my program. I have literally combed for hours on Google and made some progress but this is way different from when I was using Windows Forms and Datasets. The crazy thing is if I do something like this in the click event for the Datagrid.....

var mySelection = dgSearch.SelectedItem;

I can see the entire row of information. But for the life of me I cannot iterate through this data. I think it is an iList but I cannot seem to break that data down into elements.
