you can create a simple array and bind that to the datagrid as well.

for the datagrid to display data, it need to have some data in. this data can be of any type, dataset,table, array of userdefined class, etc. so, if u need to display data in the datagrid which is not from any database, create a class of your choice, declare its array, add values to the array, add that object ot the datasource of the datagrid then bind the data by calling databind(). hope this makes it more clear

I've decided to use sql but I'm having problem with seeing my datagrid? Yet I set Property visible to true what could be the Problem Thanks.
you might not have called the databind() function of the datagrid.

Grid can be bound to any Collection type. You can create a dummy datattable as following:- DataTable dt = new DataTable("Try"); dt.Columns.Add("column1"); dt.Rows.Add("one"); dt.Rows.Add("two"); dt.Rows.Add("three"); and now set the datasource to dt. Also you need to have atleast 1 row in datasource to get the grid displayed

Thank you, I was doing it like this. Hope private void Page_Load(object sender, System.EventArgs e) { if (! IsPostBack) { BindDataGrid(); } } private void BindDataGrid() { SqlCommand myCommand=new SqlCommand("SELECT * from Billing",con); SqlDataAdapter myAdapter=new SqlDataAdapter(myCommand); DataSet ds=new DataSet(); myAdapter.Fill(ds); con.Open(); myCommand.ExecuteNonQuery(); dgbilling.DataSource=ds; dgbilling.DataBind(); con.Close(); } I had ever used this same code on another program and it worked properly. could you help me from there please Thanks.

use following code- SqlDataAdapter myAdapter=new SqlDataAdapter("SELECT * from Billing", con); con.Open(); DataSet ds=new DataSet(); myAdapter.Fill(ds); con.Close(); dgbilling.DataSource=ds; dgbilling.DataBind(); you dont need sqlcommand here at all. And one suggestion - read more about what is an adapter, dataset etc why is it used n all. I think one should know why is he/she using the object in the code.

when you use data adapters you do not need to open or close the connection, it does it by itselt. if the connection was already open before calling the fill command in data-adapert, it will leave it open and if it was close, it will open it get the data and then close it. the Fill() function will get the data; so, you do not need to call the ExecuteNonQuery() command again. you might try the following: private void BindDataGrid() { SqlCommand myCommand=new SqlCommand("SELECT * from Billing",con); SqlDataAdapter myAdapter=new SqlDataAdapter(myCommand); DataSet ds=new DataSet(); myAdapter.Fill(ds); dgbilling.DataSource=ds; dgbilling.DataBind(); } this should give the required result.
