ASP.NET Webforms and Gridview, Display in a new page

Question

User2114489497 posted

I have a Gridview with 10 columns

On page 1 I only want to display 3 of them and when you click the select link, it should show all 10 columns on page 2.

My problem that I am having is that when I only have 3 visible columns on page 1, then only those 3 will be displayed on page 2, but when I have all 10 visible or displaying on page 1 then all 10 columns for that specific row gets displayed on page 2.  Is there a way to do what I want to achieve?

For some extra Info: Its for a car bid college project so its showing the CarMake, CarModel and the Car Image, so when I click on select, all 10 columns should be on page 2.

Any help would be appreciated and sorry if the question is duplicated.

Hi Dreyer,
 

According to your description, I made a demo for you as a reference.

if you want to show three columns, e.g. id1,id2 and id3.

you can add the  <Columns> tag inside the GridView tag and add up the columns of your choice.

The code:

The code:

WebForm1:
<div>
            <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false">
                <Columns>

                    <asp:BoundField DataField="Id1" HeaderText="Id1" />

                    <asp:BoundField DataField="Id2" HeaderText="Id2" />

                    <asp:BoundField DataField="Id3" HeaderText="Id3" />
                </Columns>
            </asp:GridView>
            <asp:LinkButton ID="LinkButton1" runat="server" OnClick="LinkButton1_Click">select link</asp:LinkButton>
        </div>
public string s = ConfigurationManager.ConnectionStrings["constr527"].ConnectionString;
        protected void Page_Load(object sender, EventArgs e)
        {
            if (!IsPostBack)
            {
                string query = "select * from Test2";
                using(SqlConnection con=new SqlConnection(s))
                {
                    using(SqlDataAdapter adapter=new SqlDataAdapter(query, con))
                    {
                        DataTable dt = new DataTable();
                        adapter.Fill(dt);
                        GridView1.DataSource = dt;
                        GridView1.DataBind();
                    }
                }
            }
        }

        protected void LinkButton1_Click(object sender, EventArgs e)
        {
            Response.Redirect("WebForm2.aspx");
        }

Web Form2:
<div>
            <asp:GridView ID="GridView1" runat="server"></asp:GridView>
        </div>
public string s = ConfigurationManager.ConnectionStrings["constr527"].ConnectionString;
        protected void Page_Load(object sender, EventArgs e)
        {
            if (!IsPostBack)
            {
                string query = "select  * from Test2";
                using (SqlConnection con = new SqlConnection(s))
                {
                    using (SqlDataAdapter adapter = new SqlDataAdapter(query, con))
                    {
                        DataTable dt = new DataTable();
                        adapter.Fill(dt);
                        GridView1.DataSource = dt;
                        GridView1.DataBind();
                    }
                }
            }
        }

The result:
