 PLLink.Visible = false; PLBuy.Visible = true;

PLLink.Visible = true;  PLBuy.Visible = false;

and if show="download and buy"(contain both of them)

 PLLink.Visible = false; PLBuy.Visible = true;

I hope explain clearly

Hi nedash,

I have created sample. Refer the below code.

HTM

<asp:GridView runat="server" ID="GridView1" AutoGenerateColumns="false" OnRowDataBound="RowDataBound">
    <Columns>
        <asp:BoundField DataField="Id" HeaderText="Id" />
        <asp:BoundField DataField="Show" HeaderText="Show" />
        <asp:BoundField DataField="Name" HeaderText="Name" />
        <asp:BoundField DataField="Code" HeaderText="Code" />
        <asp:TemplateField>
            <ItemTemplate>
                <asp:LinkButton ID="PLLink" Text="Link" runat="server" />
                &nbsp;
                <asp:LinkButton ID="PLBuy" Text="Buy" runat="server" />
            </ItemTemplate>
        </asp:TemplateField>
    </Columns>
</asp:GridView>

Code

protected void Page_Load(object sender, EventArgs e)
{
    if (!this.IsPostBack)
    {
        DataTable dt = new DataTable();
        dt.Columns.AddRange(new DataColumn[4] { new DataColumn("Id"), new DataColumn("Show"), new DataColumn("Name"), new DataColumn("Code") });
        dt.Rows.Add(1, "Buy", "Waterfall", 1111);
        dt.Rows.Add(2, "Download", "Waterfall", 1111);
        dt.Rows.Add(3, "Download and Buy", "Green", 2222);
        Session["Order"] = dt;
        GridView1.DataSource = dt;
        GridView1.DataBind();
    }
}
protected void RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        LinkButton PLLink = e.Row.FindControl("PLLink") as LinkButton;
        LinkButton PLBuy = e.Row.FindControl("PLBuy") as LinkButton;
        if (Session["Order"] != null)
        {
            DataTable dt = Session["Order"] as DataTable;
            if (dt.Rows.Count > 0)
            {
                if (dt.Rows[e.Row.RowIndex]["show"].ToString().ToLower() == "buy")
                {
                    PLLink.Visible = false;
                    PLBuy.Visible = true;
                }
                else if (dt.Rows[e.Row.RowIndex]["show"].ToString().ToLower() == "download")
                {
                    PLLink.Visible = true;
                    PLBuy.Visible = false;
                }
                else if (dt.Rows[e.Row.RowIndex]["show"].ToString().ToLower() == "download and duy")
                {
                    PLLink.Visible = false;
                    PLBuy.Visible = true;
                }
            }
        }
    }
}

hi dharmendr

I used your code in below metod:

   private void GetDocumentInfo(int pageIndex)
    {

        using (SqlConnection conn = General.GetConnection())
        {
            using (SqlCommand cmd = General.GetCommand("NewOrder_Info", conn))
            {
                int data1 = Convert.ToInt32(Request.QueryString["PeygiriCode"].ToString());
                cmd.CommandType = CommandType.StoredProcedure;
                cmd.Parameters.AddWithValue("@PageIndex", pageIndex);
                cmd.Parameters.AddWithValue("@PageSize", PageSize);
                cmd.Parameters.AddWithValue("@PeygiriCode", data1);
                cmd.Parameters.Add("@RecordCount", SqlDbType.Int, 4);
                cmd.Parameters["@RecordCount"].Direction = ParameterDirection.Output;
                conn.Open();
                SqlDataReader idr = cmd.ExecuteReader();
                if (idr.HasRows)
                {

                    if (idr.Rows[e.Row.RowIndex]["show"].ToString().ToLower() == "buy")
                    {
                        PLLink.Visible = false;
                        PLBuy.Visible = true;
                    }
                    else if (idr.Rows[e.Row.RowIndex]["show"].ToString().ToLower() == "download")
                    {
                        PLLink.Visible = true;
                        PLBuy.Visible = false;
                    }
                    else if (idr.Rows[e.Row.RowIndex]["show"].ToString().ToLower() == "download and duy")
                    {
                        PLLink.Visible = false;
                        PLBuy.Visible = true;
                    }


                    gvOrders.DataSource = idr;
                    gvOrders.DataBind();

                }
                else
                {
                    gvOrders.DataSource = idr;
                    gvOrders.DataBind();
                }
                idr.Close();
            }
        }
    }

but below error happen:

Server Error in '/' Application.

Instead of using SqlDataReader use SqlDataAdapter and fill the datatable and chack with your code.
