Here is my code. I want to find gridview ("grdVDetails") inside anchor tag ("lnkVoucher") in another gridview ("grdVoucher"). But it returns null. Please help.

ASP.NET

<asp:GridView ID="grdVoucher" runat="server" AutoGenerateColumns="False" OnRowCommand="grdVoucher_RowCommand"
        OnRowDataBound="grdVoucher_RowDataBound" Width="100%">
        <Columns>
            <asp:TemplateField HeaderText="Voucher No">
                <ItemTemplate>
                    <a id="lnkVoucher" href="java<!-- no -->script:" runat="server">
                        <div id="HidePODetail">
                            <asp:GridView ID="grdVDetails" runat="server" AutoGenerateColumns="False" OnRowDataBound="grdVDetails_RowDataBound"
                                Width="100%">
                                <Columns>
                                    <asp:TemplateField HeaderText="Head Code">
                                        <ItemStyle HorizontalAlign="Center" />
                                    </asp:TemplateField>
                                    <asp:TemplateField HeaderText="Head Name"></asp:TemplateField>
                                    <asp:TemplateField HeaderText="Debit"></asp:TemplateField>
                                    <asp:TemplateField HeaderText="Credit"></asp:TemplateField>
                                </Columns>
                            </asp:GridView>
                        </div>
                    </a>
                </ItemTemplate>
                <ItemStyle HorizontalAlign="Center" />
            </asp:TemplateField>
        </Columns>
    </asp:GridView>

C# code is:

C#

protected void grdVoucher_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            sp_Acc_ReadAll_JournalVoucherResult entry = e.Row.DataItem as sp_Acc_ReadAll_JournalVoucherResult;


            HtmlAnchor lnkVoucher = e.Row.FindControl("lnkVoucher") as HtmlAnchor;
            lnkVoucher.InnerText = entry.VoucherNo;

            GridView grdVDetails = e.Row.FindControl("grdVDetails") as GridView;
            List<Acc_Transation> list = CAccTransation.GetAllTransationByVoucherCode(entry.VoucherNo);
            grdVDetails.DataSource = list;
            grdVDetails.DataBind();
        }
    }

Oh I solved it myself. I just use another tag to bind data innertext on it and make free the innertext of anchor tag. Then I easily get the gridview.

C#

protected void grdVoucher_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            sp_Acc_ReadAll_JournalVoucherResult entry = e.Row.DataItem as sp_Acc_ReadAll_JournalVoucherResult;


            HtmlAnchor lnkVoucher = e.Row.FindControl("lnkVoucher") as HtmlAnchor;
            //lnkVoucher.InnerText = entry.VoucherNo;            
            HtmlGenericControl spVoucher = e.Row.FindControl("spVoucher") as HtmlGenericControl;
            spVoucher.InnerText = entry.VoucherNo;

            e.Row.Cells[1].Text = entry.Debit.ToString();
            e.Row.Cells[2].Text = entry.Credit.ToString();
            e.Row.Cells[3].Text = Convert.ToDateTime(entry.Date).ToShortDateString();
LinkButton lnkEdit = e.Row.FindControl("lnkEdit") as LinkButton;
            lnkEdit.CommandArgument = entry.VoucherNo;

            LinkButton lnkDelete = e.Row.FindControl("lnkDelete") as LinkButton;
            lnkDelete.CommandArgument = entry.VoucherNo;
            

            GridView grdVDetails = e.Row.FindControl("grdVDetails") as GridView;
            List<Acc_Transation> list = CAccTransation.GetAllTransationByVoucherCode(entry.VoucherNo);
            grdVDetails.DataSource = list;
            grdVDetails.DataBind();
        }
    }
