passing data from a page to another

Heaven Valenzona

hello. I've created a page that has a gridview that when you selected a row on it, the data will pass into another page.. the code is this:

1stpage.aspx

 .......

..........

 2ndPage.aspx.cs

..........

  
    protected void Page_Load(object sender, EventArgs e)
    {
        string strNo = Request.QueryString["no"];
        string strDesc = Request.QueryString["desc"];
        string strType = Request.QueryString["type"];
        string strUsername = Request.QueryString["username"];

        Label2.Text = strNo;
        Label3.Text = strDesc;
        Label9.Text = strType;
        Label10.Text = strUsername;

...........

the passing of data from the gridview into the page of 2nd page worked!

but, I wanted to pass also the data from 2nd page that has been passed from 1st page.

here's my other part of the code in 2ndpage.aspx.cs

 ........

  protected void Button1_Click(object sender, EventArgs e)
    {
        Response.Redirect("SE_TimeDtLs.aspx?strDesc=" + Server.UrlEncode(Label3.Text) + "&strNo=" + Label2.Text + "&strType=" + Label9.Text + "&strUsername=" + Label10.Text);

      
    }

.......

SE_TimeDtLs is my 3rd page. There's no output from it..

Where did I go wrong? please help.

thank you so much.

hello sir. It doesn't work. :( I don't know what's the problem.
Sir, from your code: <asp:GridView runat ="Server" ID="Gridview1" AutoGenerateColumns="False"AutoGenerateSelectButton="True">
<Columns >

sir is this just typographical error or a part of the process? At first, I use the default code like this:

   DataKeyNames="Job_No" DataSourceID="SqlDataSource1"
   onselectedindexchanged="GridView1_SelectedIndexChanged">

----there's no error from this, But, the passing of data to another page didn't worked.
----Then I follow your code, replacing the ID from RUNAT.. the same as your given code sir.
And then again, It didn't work :( *sigh*

from your code:
session["name"]=txtname .Text;
  session["marks"]= txtmarks .Text;
I changed it to :
txtname.Text = Session["name"];
txtmarks.Text = Session["marks"];
because it gives error.

But then again, I cannot passed data to another page./.
please help.. I'm a newbie here sir. Thank you very much

Hi,
to solve your problem,you have to use the SESSIOn.
look in the following example:-
<asp:GridView runat ="Server" ID="Gridview1" AutoGenerateColumns="False" AutoGenerateSelectButton="True">
<Columns >
    <asp:BoundField HeaderText ="Name" DataField ="Name" />
    <asp:BoundField HeaderText ="Marks" DataField ="marks" />
    Columns>
asp:GridView>
In Gridview Events double Click on SelectedIndexChanged Event and write the below code:

   protected void Gridview1_SelectedIndexChanged(object sender, EventArgs e)
    {
       txtname .Text = Gridview1.SelectedRow.Cells[2].Text;
       txtmarks .Text = Gridview1.SelectedRow.Cells[3].Text;
            //storing the data in   Session
   session["name"]=txtname .Text;
session["marks"]= txtmarks .Text;
    }
in page2.aspx page
protected void Page_Load(object sender, EventArgs e)
{
label1.Text=session["name"];
label2.Text=session["marks"];
}

in page1.aspx page
protected void Page_Load(object sender, EventArgs e)
{
label1.Text=session["name"];
label2.Text=session["marks"];
}
note:-By using SESSION you can pass data from one to another page untill the user clsoe the browser.
