GridView pass parameter in url and use in another page

Question

I'm able to pass the parameter in the URL, however, i'm unsure of how to grab that ID on the next page.

I'm using a GridView to pass the parameter onclick, below is the code i'm using.

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        e.Row.Attributes["onmouseover"] = "this.style.color='Black';this.style.cursor='hand';";
        e.Row.Attributes["onmouseout"] = "this.style.color='Black';";
        e.Row.Attributes["onclick"] = "window.navigate('NavigatedPage.aspx?id=" + e.Row.Cells[0].Text.ToString().Trim() + "')";
    }
}

i need what's after the id=

Thanks!

I could be mistaken from what your trying to ask, but I think your trying to accertain how to access the query string parameter on a new page. If this is the case then it's

Request.QueryString["name"]

But remember to check if its got some contents first

What I like to do is

string GetQueryStringVarible(string name, string defaultValue)
{
  if(!string.IsNullOrEmpty(Request.QueryString[name])
  { 
    return Request.QueryString[name];
  } 
  else 
  {
    return defaultValue;
  }
}

On the next page, do:

 string id =Request.QueryString["id"];
