I think you have sent query string with the page reference so you should send some basic key(s) as a search keayword and you have to catch that keys in Page_Load() event of other page on that you have redirected...

In the page.....
FindDocument.aspx

protected void Page_Load(object sender, EventArgs e)
{
     if(Request["str"] != null)
     {
           string key = Convert.ToString(Request["str"]);
           // here you have got the key that you have sent before as a querystring...
           // Now add here your basic search functionality...
           

           // you can fire a query here like this...... 
           string query = @"Select * from tableName WEHRE keyfield=@keyfield";
           // adding a parameter...
           SqlCommand cmd = new SqlCommand(query,con); // where con is a object of SqlConnection class that you have to Initiate before..
           cmd.Parameter.Add("@keyfield",key);
           SqlDataReader dr = cmd.ExecuteReader();
           //Now, here you got the data that you want.. display it in proper control like Gridview or DataList or etc...
     }
}

I hope this may help you.....
Thanks..

Solution 1

Try below javascript function:
function PassBackValue(val)
{
opener.window.getElementById('your_control_name').value = val;
}

Here your_control_name may be a control which you want to update on the pop-up (or 2nd page) close. Call this function on some appropriate event.
