推荐答案

DataGrid只是检索和显示数据的一种简单方法(快捷方式").当然，您可以不使用DataGrid而连接到数据库并检索数据:只需使用DataSet s和DataTable s.
周围有许多教程，例如:数据集和数据适配器" [ ^ ].

DataGrid is just a simple way (a ''shortcut'') for retrieving and displaying data. Of course you may connect to the database and retrieve data without using a DataGrid: just use DataSets and DataTables.
There are many tutorial around, see, for instance: "Data Sets and Data Adapters"[^].

不知何故我感觉到您正在谈论绑定...
您可以绑定到文本框，就像可以绑定到DataGridViews一样.

Somehow I get a feeling you are talking about binding...
You can bind to Textboxes just like you can bind to DataGridViews.

TextBox1.Bindings.Add("Text", MyDataSourceObject, "MyDataSourceProperty")

或者，您可以从属性"网格中添加绑定.寻找(DataBindings).
它称为简单绑定.

Alternatively you can add Bindings from the Property Grid. Look for (DataBindings).
It is called Simple Binding.

Alternatively, without binding, you could simply fetch a DataRow from your database and pretty much assign a columns value to your TextBox.Text Property.
