[英]How add row to DataGrid?
I have small program for edit XML-files. 我有一个用于编辑XML文件的小程序。 I using XMLDataProvider:
我使用XMLDataProvider:
<Grid.DataContext>
<XmlDataProvider x:Name="XMLData" Source="/database/stroyka1.bas" XPath="JobArray/job"/>
</Grid.DataContext>
and DataGrid: 和DataGrid:
<DataGrid
Name="JobsDataGrid"
ItemsSource="{Binding}"
AutoGenerateColumns="false" Height="Auto" Width="Auto"
IsReadOnly="False" CanUserAddRows="True">
<DataGrid.Columns>
<DataGridTextColumn Header="ID" Binding="{Binding XPath=id, Mode=TwoWay}" />
<DataGridTextColumn Header="Название" Binding="{Binding XPath=name, Mode=TwoWay}" />
<DataGridTextColumn Header="Цена за единицу" Binding="{Binding XPath=price, Mode=TwoWay}"/>
<DataGridTextColumn Header="Единица измерения" Binding="{Binding XPath=measure, Mode=TwoWay}"/>
</DataGrid.Columns>
</DataGrid>
How to enable a blank row below the table? 如何启用表格下方的空白行?
CanUserAddRow=true
and IsReadOnly=false
not work. CanUserAddRow=true
和IsReadOnly=false
无效。 I tried add row with blank parameters to DataGrid, but have error: 我尝试将带有空白参数的行添加到DataGrid,但是出现错误:
Operation is not allowed when using ItemsSource.
使用ItemsSource时不允许进行操作。 Instead, access and modify elements using ItemsControl.ItemsSource.
而是使用ItemsControl.ItemsSource访问和修改元素。
Thanks a lot, but i find method, but i crutch for this question. 非常感谢,但是我找到了方法,但是我想问这个问题。 I use this code:
我使用以下代码:
private void AddNewRowMenuItem_OnClick(object sender, RoutedEventArgs e)
{
job pipainput = new job(JobsDataGrid.Items.Count+1,"",0,"");
XmlSerializer xmls = new XmlSerializer(typeof(job));
var sb = new StringBuilder(512);
using (System.IO.StringWriter sw = new System.IO.StringWriter(sb))
{
xmls.Serialize(sw, pipainput);
}
XmlDocument xmlk = new XmlDocument();
xmlk.LoadXml(sb.ToString());
XmlNode pipa = XMLData.Document.ImportNode(xmlk.ChildNodes[1], true);
XMLData.Document.DocumentElement.AppendChild(pipa);
}
when job - my class. 上班时间-我的班级。 Works perfectly.
完美运作。
