How to pass information between web forms in asp.net

Question

how to send some information from one web form to another web form in asp.net first web form is HumanList.aspx that shows the list of humans in a GridView

Answer 1

Say You have a gridview1 with a button field Say "Modify" First Provide a command Name to that field Say "Mod" Now in Gridview1_RowCommand() function of HumanList.aspx page write the code like this-

switch (e.CommandName.Trim())
{
case "Mod":
int r1=Int32.Parse((e.CommandArgument).ToString());
Session["id"]=GridView1.DataKeys[r1].Value.ToString();
Response.Redirect("HumanEdit.aspx?id=" + Session["id"]);
break;
}

Now in HumanEdit.aspx.cs you can make your own class and with in that class you can have a datatable object.Store the Sql query in that object and call that class in page_load(). Say class is

Public void show()
{
Within datatable object you can write your query like this
select x,y,z, from tbl_name where id=" + Request.QueryString["id"]
if(dt.Rows.Count>0)
{
Xtext.Text=dt.Rows[0]["x"].ToString();
Ytext.Text=dt.Rows[0]["y"].ToString();
Ztext.Text=dt.Rows[0]["z"].ToString();
}
}

This much of code is enough to get what you want.
