[XAML]尝试以编程方式合并gridview中的单元格 [英] [XAML] Trying to merge cells in a gridview programmatically

问题描述

早上好。我正在制作电视指南类型的应用程序，我正在使用GridView。我有数据进入gridview，但我遇到了一些问题。首先，我想让它看起来更像一个网格，我不确定是什么设置导致它
在每行上下都有大的边距，并且每个单元格周围没有边框。我还希望能够根据单元格的内容设置columnspan，所以如果我有一个空白单元格，那么之前的单元格和这个空白单元格应该变为1个单元格，其中
来自前一个单元格的内容，如合并excel中的单元格。我似乎无法弄清楚如何读取单元格内容然后更改columnspan。如果可以，请帮助我。

Good morning. I am making a TV Guide type app and I am using a GridView. I have the data going into the gridview but I am having a couple of issues. Firstly, I would like to make it look more like a grid and I am not sure what settings are causing it to have large margins above and below each row and to not have borders around each cell. I also want to be able to set columnspan based on the content of a cell, so if I have a blank cell then the cell before that and this blank cell should become 1 cell with the content from the previous cell, like merge cell in excel. I cannot seem to figure out how to read the cell contents and then change the columnspan. Please help me if you can.

非常感谢

推荐答案

不幸的是，GridView和Excel并不完全相同。 

GridView and Excel are not quite the same, unfortunately. 

网上有很多关于如何在网格视图中测试和合并单元格的示例，搜索将各种产品从HTML返回到ASP.NET，所以我很感激你的混淆。

There are number of examples on the web on how to test and merge cells in a grid view, the search returns all kinds of products from HTML to ASP.NET, so I can appreciate your confusion.

我使用以下示例来帮助我开始一个新项目：
WPF DataGrid控件 ，我刚刚使用VS 2015社区/企业版检查了代码，它在2016年3月7日在Windows 10 10586 1511上运行。

I use the following examples to get me started with a new project: WPF DataGrid Control , I checked the code just now using VS 2015 Community/Enterprise editions and it worked on 3/7/2016 running on Windows 10 10586 1511.

您可能需要设置属性或使用内置样式属性，因此请查看以下链接：

样式控件，这将帮助您快速掌握样式，这将解决您的边界问题。

It is likely you need to set up attributes or use built-in style attributes so take a look at this link: Styling controls , this will help you get up to speed on styles, which should fix your border issues.

对于单元格的合并，请考虑这一点：

For the merging of cells consider this:

使用ItemDataBound中的列，否则，在ItemCreated中进行修改，您的代码可能看起来像执行空白单元格测试后，执行以下操作：

use the columns in ItemDataBound, otherwise, do the modifications in ItemCreated and your code might look like the following after performing your test for blank cell:

' set colspan 
 e.Item.Cells(2).ColumnSpan = 3 
 e.Item.Cells(3).Remove 
 e.Item.Cells(3).Remove
