Check this following code

protected void Gridview1_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["connection"].ConnectionString);
            DropDownList ddlDropDownList = (DropDownList)e.Row.FindControl("ddl1");
if (ddlDropDownList != null)
            {
                SqlDataAdapter da = new SqlDataAdapter("select distinct(source) from pickupdroptariff", con);
                DataTable dt = new DataTable();
                da.Fill(dt);
                if (dt.Rows.Count > 0)
                {
                    ddlDropDownList.DataSource = dt;
                    ddlDropDownList.DataTextField = "source";
                    ddlDropDownList.DataValueField = "source";
                    ddlDropDownList.DataBind();
                    ddlDropDownList.Items.Insert(0, "--Select--");

                }
                else
                {
                    ScriptManager.RegisterStartupScript(this, this.GetType(), "script", "alert('Source Not Available');", true);
                }
            }
}

Try this

C#

protected void GridView1_RowDataBound(Object sender, GridViewRowEventArgs e)
{
 if (e.Row.RowType == DataControlRowType.DataRow)       
 {
    // your code to get data 
   // I assumed you are getting data in dataset using some query

   DropDownList ddlUserName = (DropDownList)e.Row.FindControl("ddlUserName");
   ddlUserName .DataSource = dataset.Tables[0].DefaultView;
   ddlUserName .DataValueField = "ValueField"; 
   ddlUserName .DataTextField = "TextField";
   ddlUserName .DataBind();
 }
}

C#

protected void Gridview1_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {        
           ddlDropDownList.DataSource = dt;
           ddlDropDownList.DataBind();
           ddlDropDownList.DataTextField = "Binds_Field_to_show";
           ddlDropDownList.DataValueField = "Binds_Field_of_Data";
           ddlDropDownList.Items.Insert(0, "--Select--");           
        }

    }

Don't you have access to google? These are the basics of Asp.Net. You could have tried searching the problem in google. If you are unable to do so or getting some problem then you should ask the question here.
Try this:

C#

protected void GridView1_RowDataBound(Object sender, GridViewRowEventArgs e)
{
     if (e.Row is DataRow)       
     {
           DropDownList ddlTest = (DropDownList)e.Row.FindControl("ddlTest");
           ddlTest.DataSource = dt;//dt is your datatable with columns ID, Name
           ddlTest.DataValueField = "ID"; 
           ddlTest.DataTextField = "Name";
           ddlTest.DataBind();
     }
}
