Question

I am currently developing a desktop application.

I have a DataTable filled up. How do I insert those data to the DataGridView?

Answer 1

try this,

//the DataGridView
DataGridView myDataGriView = new DataGridView();

//Declare BindingSource to sync DataGridView and data table
BindingSource myBindingSource = new BindingSource();

//set the DataSource property of your BindingSource 
myBindingSource.DataSource = myDataTable;

//set the DataSource property of your DataGridView 
myDataGridView.DataSource = myBindingSource;

Hope it helped,
