WPF datagrid empty row at bottom
提问by WtFudgE
I bind my datagrid using
我使用绑定我的数据网格
//fill datagrid
public DataTable GameData
{
get
{
DataSet ds = new DataSet();
FileStream fs = new FileStream(IMDB.WebPage.Class.Config.XMLPath,
FileMode.Open, FileAccess.Read);
StreamReader reader = new StreamReader(fs, Encoding.Default);
ds.ReadXml(reader);
fs.Close();
DataTable temp = ds.Tables[0];
return ds.Tables[0];
}
}
For some reason I get an empty row at the bottom. And sometimes after clicking on some buttons and checkboxes in the grid, more empty rows are added.
出于某种原因，我在底部得到一个空行。有时在单击网格中的某些按钮和复选框后，会添加更多空行。
Why is this? And how do I block this?
为什么是这样？我该如何阻止？

Sounds like you probably have CanUserAddRowsset to true for the DataGrid. Just add
听起来您可能已将CanUserAddRowsDataGrid 设置为 true。只需添加
CanUserAddRows="false"
to the XAML.
到 XAML。

It also works with the attribute:
它也适用于以下属性：
IsReadOnly="true"

If your backing collection that implements IEditableCollectionViewreturns true from its CanAddNewmethod, the DataGrid will assume that is what you want to do.
如果实现的后备集合IEditableCollectionView从其CanAddNew方法返回 true ，则 DataGrid 将假定这就是您想要执行的操作。

If you're creating DataGrid on-the-fly through Source Code...
如果您正在通过源代码即时创建 DataGrid...
DataGrid grid = new DataGrid();
grid.CanUserAddRows = false;
//...
grid.AutoGenerateColumns = false;
grid.Margin = new Thickness(10,20,10,10);
grid.VerticalAlignment = VerticalAlignment.Top;
grid.ItemsSource = //... and so on

Though the OP was asking how to REMOVE the empty row, the title isn't specific, and this article appeared in my search while trying to figure out how to ADD the empty row. I found that, for the empty row to appear, it not only needs to have CanUserAddRows="True"but the ItemsSourceneeds to have a default constructor public MyClass () { }.
虽然 OP 询问如何删除空行，但标题并不具体，这篇文章出现在我的搜索中，同时试图找出如何添加空行。我发现，要显示空行，它不仅需要具有，CanUserAddRows="True"还ItemsSource需要具有默认构造函数public MyClass () { }。
