无法在wpf中的datagird中添加行 [英] can not add rows in datagird in wpf

问题描述

大家好.....
我想在WPF的datagrid中动态添加行
是吗?

Hi Everyone.....
I want to add rows dynamically in datagrid in WPF
Is it right ?

dataGrid1.Items.Add(object newitem);

因为在我的程序中实际上添加了行，但未显示值...表示空白行..仅增加了行数.


谢谢您.

because in my program actually rows added but values are not shown ...means blank rows..only number of lines are incremented.


Thank You

推荐答案

与其将新对象添加到".items"集合中，不如采用数据绑定方法.听起来，您实际上已经成功添加了该行，但是还没有告诉Datagrid它应如何显示该行中的数据(例如，使用数据模板).请查看本教程以获取更多信息: http://wpftutorial.net/DataGrid.html

如果不是这种情况，那么我们将需要查看一些代码，最好是XAML& C#.

希望对您有所帮助.

Rather than adding new objects to the ".items" collection you may be better off taking a databinding approach. By sounds of things you are in fact adding the row successfully, but haven''t told the datagrid how it should display the data in that row (using a data template, for example). Check out this tutorial for more info: http://wpftutorial.net/DataGrid.html

If this is not the case then we''ll need to see some code, preferably both XAML & C#.

Hope that helps.

好吧，这是一个完整的示例.请注意，我在表达要在XAML中显示哪些列以及如何显示.

C#位:

Okay, here''s a fully working example. Note that I''m expressing which columns I want to display, and how, in the XAML.

The C# bit:

FileInfo[] files = new DirectoryInfo(System.IO.Path.GetTempPath()).GetFiles();
foreach (FileInfo fi in files)
{
    if (fi != null)
    {
        dataGrid1.Items.Add(fi);
    }
}

XAML位:

The XAML bit:

<DataGrid x:Name="dataGrid1">
    <DataGrid.Columns>
        <DataGridTemplateColumn Header="Name">
            <DataGridTemplateColumn.CellTemplate>
                <DataTemplate>
                    <TextBlock Text="{Binding Name}" />
                </DataTemplate>
            </DataGridTemplateColumn.CellTemplate>
        </DataGridTemplateColumn>
        <DataGridTemplateColumn Header="DirectoryName">
            <DataGridTemplateColumn.CellTemplate>
                <DataTemplate>
                    <TextBlock Text="{Binding DirectoryName}" />
                </DataTemplate>
            </DataGridTemplateColumn.CellTemplate>
        </DataGridTemplateColumn>
    </DataGrid.Columns>
</DataGrid>
