How to post data from gridview on one page to detailview on another page when select is used

I need to get data from gridview on one page to detailview on other page when I use select statement.I am able to do this on same page by using following code but not able to do this on different page
protected void GridView1_SelectedIndexChanged(object sender, EventArgs e)
    {
        DetailsView1.PageIndex = GridView1.SelectedIndex;
    }
 
Is it possible that when I use select in gridview on a particular page then only that row data appear on detail view of another page. please let me know asap.

You could pass the ID of the record as a querystring to the other page e.g.
 
Response.Redirect("otherpage.aspx?id=" &  GridView1.SelectedIndex)
 

Then, you can read the id in your other page by using:
Request.Querystring("id")

You can also use Session Variable like below
 I assumed that you have used the SELECT commandField in your GridView.
 
    protected void Button1_Click(object sender, EventArgs e)
    {
       
        for (int i = 0; i < GrdiView1.Rows.Count; i++)
        {
            if (GrdiView1.SelectedIndex == i)
            {
                String id =GrdiView1.Rows[i].Cells[1].Text; //Gets the id value in the grid based on the selected index; 
                Session["Value"] = id;
                Response.Redirect("SecondPage.aspx");

            }
        }
        
    }

SecondPage.aspx

On page load you can get the value of your stored in the session variable 
protected void Page_Load(object sender, EventArgs e)
{
 
    string getid =  Session["Value"].ToString();
   //Now you can bind your DetailsView based on that id

}
