从 DataRow 获取 DefaultView DataRowView [英] Get the DefaultView DataRowView from a DataRow

问题描述

情况如下:我需要将 WPF FixedPage 与 DataRow 绑定.绑定对 DataRows 不起作用；它们对 DataRowViews 起作用.我需要以最通用的方式执行此操作，因为我对 DataRow 中的内容一无所知，也无法控制.

Here's the situation: I need to bind a WPF FixedPage against a DataRow. Bindings don't work against DataRows; they work against DataRowViews. I need to do this in the most generic way possible, as I know nothing about and have no control over what is in the DataRow.

我需要的是能够为给定的 DataRow 获取 DataRowView.我不能在 DefaultView 上使用 Find() 方法，因为它需要一个键，并且不能保证表会有一个主键集.

What I need is to be able to get a DataRowView for a given DataRow. I can't use the Find() method on the DefaultView because that takes a key, and there is no guarantee the table will have a primary key set.

是否有人对解决此问题的最佳方法提出建议?

Does anybody have a suggestion as to the best way to go around this?

推荐答案

不完全是一段性感的代码，但它们似乎不是一种无需循环表格即可自动查找行的方法.

Not Exactly a sexy piece of code but their doesn't seem to be an automated way to find the row without just looping the table.

        DataRowView newRowView = null;
        foreach (DataRowView tempRowView in myDataTable.DefaultView)
        {
            if (tempRowView.Row == rowToMatch)
                newRowView = tempRowView;
        }
        if (newRow != null)
            UseNewRowView(newRowView);
        else
            HandleRowNotFound();
