Put a Hidden field bind the question id and find it ItemDataBound

<asp:hiddenfield id=""hnQuestionsid"" runat=""server"" value="<%# DataBinder.Eval(Container.DataItem, "Questionsid")%>" xmlns:asp="#unknown" />

in code side

protected void OuterDataList_ItemDataBound(object sender, DataListItemEventArgs e)
{
DataListItem drv = e.Item.DataItem as DataListItem;
RadioButtonList RadioButtonList1 = (RadioButtonList)e.Item.FindControl("RadioButtonList1");
HiddenField hnQuestionsid = (HiddenField)e.Item.FindControl("hnQuestionsid");
DataSet ds = loadQuestionOptionbyqid(hnQuestionsid.Value);
if (ds != null && ds.Tables[0].Rows.Count > 0)
{
RadioButtonList1.DataSource = ds;
RadioButtonList1.DataTextField = "questionName";// something like this
RadioButtonList1.DataValueField = "questionID";
RadioButtonList1.DataBind();
}

}

You can bind then in gridview rowdatabound event like this.

C#

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
       {
           if (e.Row.RowType == DataControlRowType.DataRow)
           {
               int rdbValue= (int)DataBinder.Eval(e.Row.DataItem, "rdbID");
               RadioButtonList rb = (RadioButtonList)e.Row.FindControl("RadioButtonListID");
               rb.Items.FindByValue(rdbValue.ToString()).Selected = true;
           }
}

I hope you got my point.
