Hope, this will help you

Hi there is no method for adding column in asp.net

You can get datatable from griview datasource and

Add in datatable  and again bind with this datatable to gridview2.

    protected void GridView1_SelectedIndexChanged(object sender, EventArgs e)

    {

        DataTable dt = ((DataTable)GridView2.DataSource);

        dt.Rows.Add(GridView1.SelectedRow);

        GridView2.DataSource=dt;

        GridView2.DataBind();

    }

protected void Page_Load(object sender, EventArgs e)
{
try
{
if (!IsPostBack)
{
DataTable dt = new DataTable();
dt.Columns.Add("Column1");
dt.Columns.Add("Column2");
dt.AcceptChanges();

ViewState[

"key1"] = dt;
DataTable dt1 = new DataTable();
dt1.Columns.Add("Column1");
dt1.Columns.Add("Column2");

DataRow dr;
for (int i = 0; i < 3; i++)
{
dr = dt1.NewRow();
dr.BeginEdit();
dr["Column1"] = "Name" + (i + 1);
dr["Column2"] = "Address" + (i + 1);
dr.EndEdit();
dt1.Rows.Add(dr);
}

GridView1.DataSource = dt1;
GridView1.DataBind();
}
}

catch (Exception ex)
{
Response.Write(ex.Message);
}
}

protected void GridView1_SelectedIndexChanged(object sender, EventArgs e)
{
try
{
DataTable dt = (DataTable)ViewState["key1"];
DataRow dataRow;
dataRow = dt.NewRow();

int i2 = 1;
for (int i = 0; i < dataRow.Table.Columns.Count; i++)
{
dataRow[i] = GridView1.SelectedRow.Cells[i2].Text;
i2++;
}

dt.Rows.Add(dataRow);
dt.AcceptChanges();
GridView2.DataSource = dt;
GridView2.DataBind();
}

catch (Exception ex)
{
Response.Write(ex.Message);
}

}
