我有 4 个要绑定到 datagridview 的数据源,所以它会像
datasource Me.DataGridView1.DataSource = Me.bindingSource1 'rows 0 to 500
datasource Me.DataGridView1.DataSource = Me.bindingSource2 'rows 501 to 1000
datasource Me.DataGridView1.DataSource = Me.bindingSource3 'rows 1001 to 1500
datasource Me.DataGridView1.DataSource = Me.bindingSource4 'rows 1501 to 2000
怎么做到呢?
