Showing fields in the Details Form that are set invisible

Question

User-643157890 posted

I have a List.aspx with a Gridview with ten fields (columns). I wanted to show only six out of ten fields. The other 4 fields are set invisible using the smart tag to configure the data source. I enable Selection on the Gridview. When selecting, it will redirect to the ListDetails.aspx to show a specific item in detail.

//List.aspx
protected void GridView1_SelectedIndexChanged(object sender, EventArgs e)
        {
            GridViewRow row = GridView1.SelectedRow;
            Session["Id"] = row.Cells[1].Text;
            Session["Name"] = row.Cells[2].Text;
            Session["Section"] = row.Cells[3].Text;
            Session["Summary"] = row.Cells[4].Text;  
            Session["Domain"] = row.Cells[5].Text;           
            Session["Date"] = row.Cells[6].Text;

            Session["Type"] = row.Cells[7].Text;	   //does not show in the LD.aspx
            Session["Justification"] = row.Cells[8].Text;  //does not show in the LD.aspx
            Session["OfficePhone"] = row.Cells[9].Text;    //does not show in the LD.aspx
            Session["Email"] = row.Cells[10].Text;         //does not show in the LD.aspx
            
            Response.Redirect("ListDetails.aspx");
        }

//ListDetails.aspx

protected void Page_Load(object sender, EventArgs e)
        {
            if (!IsPostBack)
            {

                if (Session["Role"] != null)
                {  
                    txtId.Text = Session["Id"].ToString();
                    txtName.Text = Session["Name"].ToString();
                    txtSection.Text = Session["Section"].ToString();
                    txtSummary.Text = Session["Summary"].ToString();
                    ddlDomain.Text = Session["Domain"].ToString();
                    txtDate.Text = Session["Date"].ToString();
                    ddlType.Text = Session["Type"].ToString();
                    txtJustification.Text = Session["Justification"].ToString();
                    txtPhoneNumber.Text = Session["OfficePhone"].ToString();
                    txtEmailAddress.Text = Session["Email"].ToString();
                     
                }
            }
        }

I want to show ALL of fields including those fields that are set invisible in the List.aspx.  However, when I click on SELECT to select a row on the list, those fields that are set invisible won't show up in the ListDetails.aspx. Can you please help me to find out why and how to fix it?  Thank you in advance

I sugest you to pass id only then get detailed data based the id from db in details page

                if (Session["Role"] != null)
                {  
                    string id = Session["Id"].ToString();
                    //next data from db
                     
                }

Hi newUser15,

From your description, I suggest you could set a break point in the SelectedIndexChanged event and check whether you could get the invisible columns’ value. I suppose perhaps you are using the Visible property to make this columns invisible, which is the reason of your error. I suggest you could try to hide the columns using the CSS display attribute. Here is some code. You could refer to it.

List.aspx:

<style type="text/css">
        .countryclass{
            display:none;
        }
</style>
<asp:GridView ID="GridView1" runat="server" HeaderStyle-BackColor ="#3AC0F2" HeaderStyle-ForeColor="White" 
                RowStyle-BackColor="#A1DCF2" AlternatingRowStyle-BackColor="White" AlternatingRowStyle-ForeColor="#000"
                 AutoGenerateColumns ="False" AllowPaging ="True" OnPageIndexChanging ="onpageindexchanging" AutoGenerateSelectButton="true" OnSelectedIndexChanged="GridView1_SelectedIndexChanged" OnSelectedIndexChanging="GridView1_SelectedIndexChanging" >
<AlternatingRowStyle BackColor="White" ForeColor="#000000"></AlternatingRowStyle>
                <Columns >
                 <asp:BoundField DataField ="Contactname" HeaderText="Contactname "  ItemStyle-Width="150px">
<ItemStyle Width="150px"></ItemStyle>
                    </asp:BoundField>
                  <asp:BoundField DataField ="City" HeaderText ="City" ItemStyle-Width="100px">                   
<ItemStyle Width="100px"></ItemStyle>
                    </asp:BoundField>
                   <asp:BoundField DataField ="Country" HeaderText ="Country" ItemStyle-Width="100px"
                        ItemStyle-CssClass="countryclass" HeaderStyle-CssClass="countryclass" FooterStyle-CssClass="countryclass" >                   
<ItemStyle Width="100px"></ItemStyle>
                    </asp:BoundField>
                </Columns>            

<HeaderStyle BackColor="#3AC0F2" ForeColor="White"></HeaderStyle>

<RowStyle BackColor="#A1DCF2"></RowStyle>
            </asp:GridView>

Code Behind:

  protected void GridView1_SelectedIndexChanged(object sender, EventArgs e)
        {
            string id = GridView1.SelectedRow.Cells[0].Text;         
            Session["contactName"] = GridView1.SelectedRow.Cells[1].Text;
            Session["city"] = GridView1.SelectedRow.Cells[2].Text;                   
            Session["country"] = GridView1.SelectedRow.Cells[3].Text; 
            Response.Redirect("ListDetails.aspx ");
        }

ListDetails.aspx:

protected void Page_Load(object sender, EventArgs e)
        {
            DataTable dt = new DataTable();
            dt.Columns.AddRange(new DataColumn[3] { new DataColumn("contactname",typeof(string)),
                       new DataColumn("City",typeof(string)),
                     new DataColumn("Country",typeof(string)), });          
            string name = (string)Session["contactName"];
            string city = (string)Session["city"];
            string country = (string)Session["Country"];
            dt.Rows.Add(name, city, country);
            ListView1.DataSource = dt;
            ListView1.DataBind();
        }

Hope this can help you. If you have any question and confusion about the problem. Please don't hesitate to let me know.

Best regards,
Dillion
