ASP.NET - RadioButtonList in Edit mode of Grid using EditItemTemplate in ASP.NET

Hi All,

Actually My Problem is, RadioButtons are not selected in edit mode based on value saved in Database.

The Below Mentioned is my code in both aspx Page & aspx.cs Page.

<asp:TemplateField HeaderText="Billable" SortExpression="Billable">

              <ItemStyle HorizontalAlign ="Left" />

              <HeaderStyle HorizontalAlign ="Left" />

              <ItemTemplate><%#(Boolean.Parse(Eval("Billable").ToString())) ? "Billable" : "Non-Billable"%></ItemTemplate>

              <EditItemTemplate>

              <asp:RadioButtonList ID="rbtnlBillable" runat="server" RepeatDirection="Horizontal">

              <asp:ListItem>Billable</asp:ListItem>

              <asp:ListItem>Non-Billable</asp:ListItem>

              </asp:RadioButtonList>

              </EditItemTemplate>

            </asp:TemplateField>

            <asp:TemplateField HeaderText="Taxable" SortExpression="Taxable">

              <ItemTemplate><%#(Boolean.Parse(Eval("Taxable").ToString())) ? "Taxable" : "Non-Taxable"%></ItemTemplate>

              <EditItemTemplate>

              <asp:RadioButtonList ID="rbtnlTaxable" runat="server" RepeatDirection="Horizontal">

              <asp:ListItem>Taxable</asp:ListItem>

              <asp:ListItem>Non-Taxable</asp:ListItem>

              </asp:RadioButtonList>

              </EditItemTemplate>

            </asp:TemplateField>

protected void gvActivities_RowDataBound(object sender, GridViewRowEventArgs e)

    {

    DataRowView DRV = (DataRowView)e.Row.DataItem;

      if (e.Row.RowType == DataControlRowType.DataRow)

      {

        if ((e.Row.RowState & DataControlRowState.Edit) > 0)

        {

          RadioButtonList Billable = (RadioButtonList)e.Row.FindControl("rbtnlBillable");

          Billable.SelectedValue = DRV[2].ToString();

          RadioButtonList Taxable = (RadioButtonList)e.Row.FindControl("rbtnlTaxable");

          Taxable.SelectedValue = DRV[3].ToString();

        }

      }

    }

The Below Image is that after clicking on edit button in gridview.

Regards,
