扩展数据网格 [英] Extended datagrid

问题描述

我有一个DataGrid控件，我还为其创建了几个新的扩展

DataGridColumnStyles。它们的表现相当不错，但是我无法弄清楚如何为它们实现选择项目格式化。


在普通的香草DataGrid中，当你点击RowHeader，

适当的行改变颜色。我认为这应该在有问题的DataGridColumnStyle的Paint

（或PaintText）覆盖中完成。我的问题

是我不知道如何检索DataGridColumnStyle

实例的DataGrid来测试是否选中了行。

或者，也许这不是最好的方法。任何帮助？


谢谢，

I have a DataGrid control for which I have also created several new extended
DataGridColumnStyles. They behave pretty nicely, but I can''t figure out how
to implement Selected Item formatting for them.

In a plain vanilla DataGrid, when you click on the RowHeader, the
appropriate row changes colors. I ASSUME this should be done in the Paint
(or PaintText) override of the DataGridColumnStyle in question. My problem
is that I don''t know how to retrieve the DataGrid of the DataGridColumnStyle
instance to test if the row is selected.

Or, maybe this isn''t the best way to do this. Any help?

Thanks,

推荐答案

DataGridColumnStyle类有一个名为DataGridTableStyle的属性，

又有一个DataGrid属性，它保存了一个引用DataGridColumnStyle的DataGrid

。 />

默认情况下，当在DataGrid中选择行

时，派生列应着色（突出显示）。这不会发生吗？或者我是否b / b
误解了你的问题？

The DataGridColumnStyle class has a property named DataGridTableStyle which
in turn has a DataGrid property which holds a refererence the DataGrid
hosting the DataGridColumnStyle.

By default, your derived column should be colored (highlighted) when a row
is selected in the DataGrid. Is this not happening? Or am I
misunderstanding your question?

不，这不会发生。请注意，我已经覆盖了我的派生DataGridColumnStyles中的一堆东西。

DataGridColumnStyle类有一个名为DataGridTableStyle的属性，而
又有一个DataGrid属性它持有DataGrid的参考资料
托管DataGridColumnStyle。


实际上我在第一篇文章后不久就找到了对数据网格的引用。

FORCING在测试

选择后，在DataTableStyles.BackColor中绘制的行不起作用，即DataGrid认为有问题的行是未选择的
。我似乎已经覆盖了一些通常会设置

IsSelected for the row的东西。


这会响铃吗？


谢谢，


Pat

No, this is NOT happening. Mind you, I have overridden a bunch of stuff in
my derived DataGridColumnStyles.
The DataGridColumnStyle class has a property named DataGridTableStyle which
in turn has a DataGrid property which holds a refererence the DataGrid
hosting the DataGridColumnStyle.
In fact I found the reference to the datagrid shortly after my first post.
"FORCING" the row to paint in the DataTableStyles.BackColor after testing for
selection doesn''t work, i.e. the DataGrid thinks that the row in question is
not selected. It seems I have overridden something that would ordinarily set
the IsSelected for the row.

Does this ring any bells?

Thanks,

Pat

没有铃声响起。


如果你可以在这里分享你的DataGridColumnStyle代码，或者把它发送到

我会看看。
