是否可以将DataGrid绑定到DataTable，new DataTable()在运行时设置为<DataGrid x:Name="dgClients" ItemsSource="{Binding clientsTable}">
<DataGrid.Columns>
<DataGridTextColumn Header="Id" Binding="{Binding Path=Id}"/>
<DataGridTextColumn Header="Name" Binding="{Binding Path=Name}"/>
</DataGrid.Columns>
</ViProDataGrid>
但之后填充了列和数据？这是我的XAML：
public DataTable clientsTable = new DataTable(); (global variable)
** the following code is executing after app initialization
DataTable dtTemp = SearchClients(param1);
clientsTable.Columns.Add("Id", dtTemp.Columns["oldIdColumn"].DataType);
clientsTable.Columns.Add("Name", dtTemp.Columns["oldNameColumn"].DataType);
for (int i = 0; i < dtTemp.Rows.Count; i++)
{
var tmpRow = clientsTable.NewRow();
tmpRow["Id"] = dtTemp.Rows[i]["oldIdColumn"];
tmpRow["Name"] = dtTemp.Rows[i]["oldNameColumn"];
clientsTable.Rows.Add(tmpRow);
}
这是我的c＃代码：
DataTable如果我在填充AutoGenerateColumns="False"并设置DataGrid之后在我的代码中设置了ItemsSource，DataGrid.Items.Refresh()显示的是良好的数据，但这不是我想要的方式。问题是，必须在XAML中设置列。
我尝试使用DataContext并将DataTable设置为 [Test]
public void TestExists()
{
var sql = @"with data as
(
select 1 as 'Id'
)
select CASE WHEN EXISTS (SELECT Id FROM data WHERE Id = 1)
THEN 1
ELSE 0
END AS result
from data ";
var result = _connection.Query<bool>(sql).FirstOrDefault();
Assert.That(result, Is.True);
}
。
