How to implement datagridview binding

This article mainly introduces how to achieve datagridview binding, has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, the following let the editor take you to understand it.

Before datagridview binding begins, take a look at the two forms of data binding for WinForm controls, simple data binding and complex data binding.

Simple data datagridview binding

Example 1

Using (SqlConnectionconn=newSqlConnection (ConfigurationManager.ConnectionStrings ["connStr"] .ToString ())

{

SqlDataAdaptersda=newSqlDataAdapter ("Select*FromT_ClassWhereF_Type='Product'orderbyF_RootID,F_Orders", conn)

DataSetDs=newDataSet ()

Sda.Fill (Ds, "T_Class")

/ / when using DataSet binding, you must also specify DateMember

This.dataGridView1.DataSource=Ds

This.dataGridView1.DataMember= "T_Class"

/ / you can also bind directly with DataTable

This.dataGridView1.DataSource=Ds.Tables ["T_Class"]

}

Simple data binding is to bind a property of a user control to a property on an instance of a type.

Bind in the following form: reference control .DataBindings.add (Control Properties, instance object, property name, true)

Example 2

Read the data from the database and put it in a dataset, such as List and DataTable,DataSet. I usually use List.

Then bind the data source:

IListsList=StudentDB.GetAllList ()

DataGridView.DataSource=sList

If you do not set the columns for DataGridView, it will automatically generate all columns.

Complex data datagridview binding

Complex data binding is to bind a list-based user control (such as ComboBox, ListBox, ErrorProvider, DataGridView, etc.) to a list of data objects.

Basically, WindowsForms's complex data binding allows binding to data lists that support IList interfaces. In addition, if you want to bind through a BindingSource component, you can bind to a data list that supports the IEnumerable interface.

For complex data binding, common data source types are (the code uses DataGridView as a sample control).
