Question

I am new to c#, this may be very easy question.

In my application there is a Form in which I have datagridview dgvBill and a Button btnClick. I declared columns to it by clicking the extender and selecting add columns. After executing the form, I written some text to each column in dgvBill. When I click on btnClick it is creating an xml file but with no data in it. (why the data is not being added ?)

The created XML file looks like this:

<?xml version="1.0" standalone="yes"?>
<NewDataSet />

I have tried the below code:

btnClick Event

DataSet ds = new DataSet();
ds.WriteXml(@"..\..\Customer_Info\" + lblCustId.Text + ".xml");
dgvBill.DataSource = ds;  /* also tried ds.Tables[0] */

lblCustId is a label in the Form

Optional: can I make each cell of datagridview into ComboBox?

Thanks in advance.

My problem solved when I created a new empty xml file (which has only created column names)
and read the xml file in a dataset object (on form load event). I used the same dataset object to write on different xml file (on button click event). I am sure that this is not the correct way but it worked. Please post here if you have any other good suggestions.
