I have created sample code which fullfill you requirement.

HTML

<div>
    <asp:GridView ID="gvDetails" runat="server" AutoGenerateColumns="false" OnRowDataBound="gvDetails_RowDataBound">
        <Columns>
            <asp:TemplateField ItemStyle-Wrap="false" ItemStyle-Width="104px" ItemStyle-BackColor="#9fa490"
                ItemStyle-HorizontalAlign="Center" ItemStyle-VerticalAlign="Top" ItemStyle-Height="46px">
                <ItemTemplate>
                    <div id="Div" runat="server" visible="false" class="ersal1">
                        <asp:HyperLink ID="HyperLink1" runat="server" CssClass="LBsefSe" NavigateUrl='<%# "ViewSendOrder.aspx?&PeygiriCode=" + Eval("PeygiriCode") %>'>ارسال شده1</asp:HyperLink>
                    </div>
                    <div id="Div1" runat="server" visible="false" class="ersal1">
                        <asp:HyperLink ID="HyperLink2" runat="server" CssClass="LBsefSe" NavigateUrl='<%# "ViewSendOrder.aspx?&PeygiriCode=" + Eval("PeygiriCode") %>'>ارسال شده2</asp:HyperLink>
                    </div>
                    <div id="Div2" runat="server" visible="false" class="ersal1">
                        <asp:HyperLink ID="HyperLink3" runat="server" CssClass="LBsefSe" NavigateUrl='<%# "ViewSendOrder.aspx?&PeygiriCode=" + Eval("PeygiriCode") %>'>ارسال شده3</asp:HyperLink>
                    </div>
                </ItemTemplate>
            </asp:TemplateField>
            <asp:BoundField DataField="Data" HeaderText="Data" />
        </Columns>
    </asp:GridView>
</div>

C#

protected void Page_Load(object sender, EventArgs e)
{
    if (!this.IsPostBack)
    {
        DataTable dt = new DataTable();
        dt.Columns.Add("PeygiriCode", typeof(string));
        dt.Columns.Add("Data", typeof(string));
        dt.Rows.Add("Test", "1");
        dt.Rows.Add("Test", "2");
        dt.Rows.Add("Test", "3");
        gvDetails.DataSource = dt;
        gvDetails.DataBind();
    }
}

protected void gvDetails_RowDataBound(object sender, GridViewRowEventArgs e)
{
    HtmlGenericControl myDiv;

    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        if (e.Row.Cells[1].Text == "1")
        {
            myDiv = (HtmlGenericControl)e.Row.FindControl("Div")
            as HtmlGenericControl;
            myDiv.Visible = true;
        }

        else if (e.Row.Cells[1].Text == "2")
        {
            myDiv = (HtmlGenericControl)e.Row.FindControl("Div1")
            as HtmlGenericControl;
            myDiv.Visible = true;
        }

        else if (e.Row.Cells[1].Text == "3")
        {
            myDiv = (HtmlGenericControl)e.Row.FindControl("Div2")
                as HtmlGenericControl;
            myDiv.Visible = true;
        }
    }
}
