Copy a ListView and show it on a new page

I am trying to copy a ListView from one class to another and show that ListView on a new aspx page. What I am doing is I am selecting certain values from the first ListView and only those items will be shown on a new page. However, I can't figure out how to show the ListView on a new page because I am used to using a SqlDataSource. I am passing the ListView through the addList method and I have already created a new ListView in the new aspx file.
Please let me know the best way to handle this and if I need to add more information.
Code in First Class
public void CloneButton_Click(object sender, EventArgs e)
{
String droplist = DropDownList2.SelectedValue;
list = new ListView();
if (String.IsNullOrEmpty(droplist))
{
ScriptManager.RegisterStartupScript(this, GetType(), "error", "alert('Please select a Program Name and Report Period');", true);
return;
}
else
{
if (ListView1.Items.Count == 0)
{
Button1_Click(sender, e);
}
else
{
var selectAllCheckBox = (CheckBox)ListView1.InsertItem.FindControl("CheckBox2");
if (selectAllCheckBox.Checked == true)
{
list = ListView1;
Response.Redirect("~/CloneReport.aspx");
return;
}
for (int i = 0; i < ListView1.Items.Count; i++)
{
CheckBox chk = (CheckBox)ListView1.Items[i].FindControl("CheckBox1");
if (chk.Checked == true)
{
list.Items.Add(ListView1.Items[i]);
}
}
CloneReport rep = new CloneReport();
rep.addList(list);
Response.Redirect("~/CloneReport.aspx");
}
}
}
Code in Second Class
public void addList(ListView list)
{
ListView1 = new ListView();
for (int i = 0; i < list.Items.Count; i++)
{
ListView1.Items.Add(list.Items[i]);
}
ListView1.DataBind();
}

You cannot transfer ListView object between pages, but you can do it with DataTable using Server.Transfer.
First Page:
DataTable dtTable;
public DataTable DataTransferTable
{
get { return dtTable; }
}
protected void btnSubmit_Click(object sender, EventArgs e)
{
lstTransferView = new ListView();
DataView dtView = (DataView)SqlDataSource1.Select(DataSourceSelectArguments.Empty);
dtTable = new DataTable();
dtTable = dtView.ToTable().Clone();
DataRow dtRow;
foreach (ListViewDataItem lstItem in lstView.Items)
{
if (((CheckBox)lstItem.FindControl("chkBox")).Checked)
{
dtRow = (DataRow)dtView.Table.Rows[lstItem.DataItemIndex];
dtTable.ImportRow(dtRow);
}
}
Server.Transfer("~/SecondPage.aspx");
}
Second Page:
public FirstPageClass ftPage;
DataTable dtNewTable;
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
ftPage= (FirstPageClass)Context.Handler;
dtNewTable = (DataTable)ftPage.DataTransferTable;
lstSecondView.DataSource = dtNewTable;
lstSecondView.DataBind();
}

//}
showdata();
}
When I click on any row that display only first row data. I want to get each row data by each clicking on respective textbox of grid row.
I have tried with commandfield but when try to add the data of option textbox (txtoption) in listbox with add button, it automatically display update, cancel option in gridview.

In the gvdetails_RowCommand event, you're always accessing the first row in the GridView.
int id = int.Parse(gvdetails.Rows[0].Cells[0].Text);
See if this works instead (referencing the currently selected row):
int id = int.Parse(gvdetails.SelectedRow.Cells[0].Text);

Here is a sample code for your reference. Hope this helps.
protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
{
if (e.CommandName =="edit")
{
int i = Convert.ToInt32(e.CommandArgument);
YourTextBox1.Text = GridView1.Rows[i].Cells[0].Text;
YourTextBox2.Text = GridView1.Rows[i].Cells[1].Text;
}
}

Best way to show/hide a textbox when checkbox is checked/unchecked in a datalist

I'm new to aspnet programming and need some help. I've been scouring the internet and can't find a solution to my problem. I basically need a way to have a textbox show only when it's corresponding checkbox is checked. The textboxes and checkboxes are part of an inner datalist; the controls have to be databound. I've tried JQuery and couldn't get it to work, so now I'm trying AJAX with the UpdatePanel--still not working right. Below is my current code which resides in a user control. I basically included code that pertains to the checkboxes/textboxes. The script manager is referenced in the master page. Any help would be appreciated.
Thanks in advance!

}

Try this to get the selected Rows value
ListView1.SelectedIndex = e.NewSelectedIndex;
string id=ListView1.SelectedDataKey.Value.ToString();
//Then pass the id's value
ListView1.DataBind();
Hope it helps.

load aspx page which is include listview in Masterpage that contain Updatepanel

actually I'm developing a template using ASP.net and C#.
as you can see below picture, my template include 3 part and i want to have partial refreshing, that's why i'm using updatepanel.
in this template once the user click at the top menu it will refresh the side menu then when the user click on the side menu it will refresh the middle content page.
i'm using masterpage in this scenario because i'm going to load aspx page at the middle content page. based on my code the normal page easily load at this part but when i want to load the page which is include listview:

</asp:UpdatePanel>
because i want to have partial refreshing at first i set the Visible of the ContentPlaceHolder3 to false and once the user click on the related link i just set it as true by code behind.
could you pleas guide me how to load this kind of aspx page at the masterpage.
appreciate your consideration.

i have solved this problem using User Control method.
now i have put content of the page inside uc1 and used the below code to call the page at the update panel:
<uc1:WebUserControl ID="WebUserControl1" runat="server" Visible="false" />
once the user click on the related button i just change the Visible option to True.
i hope it would be helpful.
