Datagrid returns table values twice

What would cause a datagrid to return the values from a table twice?

protected void LSales_Query(object sender, EventArgs e)

                  if (ConI.State == ConnectionState.Closed)
                        ConI.Open ();


                        string S = "(Select * from LSales where Agent = '" + D.SelectedItem.Text + "')";
                        DA = new System.Data.SqlClient.SqlDataAdapter(S, ConI);
                        DataTable Dtable = new DataTable();
                        //DA.Fill(DS, "LSales");
                        DA.Fill(DS, "LSales");
                        DG.DataSource =DS;

Hi, devlins.

Can you explain a little more? Some additional info is needed.

What is ConI and what is LConn?
When do you call LSales_Query() method?
Why do you use: DS.Tables.Add();  ?

DS is the dataset.Tables.Add();
ICon was a goof up!
I changed it to LCon which is the database connection

As I understand you see all your rows twice.
What is the order? 1,2,3... 1,2,3...   or   1,1,2,2,3,3...
Are you sure your table contains just one instance of each row?
What is your updated code?

123... 123....

all in the same row, has two of the same table side by side...

The code I posted above is the code that I am using.... which only has a single instance of each...
It just because currently, your datagird already have data on it. When you bind new datasource, it will add more to your grid (it mean did not re-bind data).

In your DataBind() function, you need to clear the DataSource first before you bind new datasource to it.

// clear data source
DataGrid.DataSource = null;
// bind new DataSource
DataGrid.DataSource = NewDataSource;
