An explanation of the method of implementing value between ASP

Suppose there are TextBox1 text boxes and open buttons on the parentform.aspx page
Click the Open button to eject the Subform.aspx,subform.aspx page with the TextBox1 text box and the Close button
Click the Close button to close the Subform.aspx page and display the value of the page subform.aspx text box to the text box parentform.aspx the parent page.

Parent form Foreground Code:

Code to copy code as follows
<script type= "Text/javascript" >
function Opensubform (ret) {
var strpath = "Http://www.111Cn.NeT/subForm.aspx"
var nheight = 500
var nwidth = 500
var feature
Feature = "height=" + nheight + ", width=" + nwidth + ", top=30,left=30";
Feature + = ", dependent=yes,location=no,resizable=yes,scrollbars=yes,status=yes,toolbar=no;";
window.open (strpath+ "? Ret_form=form1&ret_value= "+ret, ' subform ', feature). focus ();
return false;
}
</script>

Parent Form Background Code:

The code is as follows
private void Page_Load (object sender, System.EventArgs e)
{
ペ?ジを in the early stages of するユ?ザ? コ?ドをここに Brown in raft/> this. BUTTON1.ATTRIBUTES.ADD ("OnClick", "Return Opensubform (' TextBox1 ');");
}

Child form Background code:

The code is as follows

private void Button1_Click (object sender, System.EventArgs e)
{
String Strscript =string. Empty;
string strretform = String.Empty;
String Strretvalue=string.empty;
strretform=request.params["Ret_form"];
strretvalue=request.params["Ret_value"];
if (Strretform = = string. Empty)
{
Strretform= "Document.forms[0]";
}
Strscript = "<script language=javascript>";
Strscript + = "Window.opener" + strretform;
Strscript + = "." + Strretvalue + ". Value= '" + this. TextBox1.Text.Trim () + "';";
Strscript + = "window.close ();";
Strscript + = "</script>";
Response.Write (Strscript);
}

Above is the JS is actually the page value, the following I put some page value code for reference.

Several ways to transfer values between pages.

The following code snippet demonstrates how to implement this method:
Part of the code in the source page WebForm1.aspx.cs:

The code is as follows
private void Button1_Click (object sender, System.EventArgs e)
{
string URL;
Url= "Webform2.aspx?name=" + TextBox1.Text + "&email=" + TextBox2.Text;
Response.Redirect (URL);
}
Part of the code in the target page WebForm2.aspx.cs:
private void Page_Load (object sender, System.EventArgs e)
{
label1.text=request.querystring["Name"];
label2.text=request.querystring["email"];
}

Using Session Variables

Part of the code in the source page WebForm1.aspx.cs:

The code is as follows
private void Button1_Click (object sender, System.EventArgs e)
{
TextBox1 and TextBox2 are WebForm
Controls
session["Name"]=textbox1.text;
session["Email"]=textbox2.text;
Server.Transfer ("webform2.aspx");
}

Part of the code in the target page WebForm2.aspx.cs:

The code is as follows
private void Page_Load (object sender, System.EventArgs e)
{
label1.text=session["Name"]. ToString ();
label2.text=session["Email"]. ToString ();
Session.remove ("name");
Session.remove ("email");
}

The above two are commonly used in the other is not introduced, we can refer to their own
