DataGrid的必然数据表不清爽值 [英] DataGrid bound to Datatable not refreshing Values

问题描述

我已经被绑定到一个DataTable（LastDatasets）

I've a DataGrid which is bound to a DataTable ("LastDatasets")

当我通过这个code刷新计时器的数据表：

When I refresh the DataTable in a Timer via this code:

if (LastDatasets != null)
{
    var maxRow = LastDatasets.Select("id = MAX(id)").FirstOrDefault();

    var newds = dataInterface.ReadFromDatabase("SELECT * FROM daten WHERE id > " + dataInterface.SqlSep + "id LIMIT 30", new Dictionary<string, object>() {{"id", maxRow["id"]}});

    if (newds != null && newds.Rows.Count > 0)
    {
        LastDatasets.Merge(newds);
    }               
}

我的DataTable包含我的新数据，但在DataGrid的WPF没有刷新！

My DataTable contains my new data, but the DataGrid in WPF is not refreshed!

推荐答案

我用简单的绑定，我可以看到.Merge后的所有更改（）。所以你应该张贴一些code，看看怎么回事错了。

i use simple binding and i can see all changes after .Merge(). so you should post some more code to see whats going wrong.

 <DataGrid ItemsSource="{Binding MyDataTable}" />

vm.cs

 MyDataTable.Merge(newdata);
