Hi Guys,

Im busy creating a betting application using C# asp.net.
Pretty much what happens is, at betting sites cashiers will log onto the website and may generate a voucher which is printed and given to customers.

I am using a masterPage, the RadScriptManager and AjaxManager are found on the master page.
My Sales.aspx page which has a RadAjaxPanel which holds a RadMultiPage control that has 2 tabs (scratchcards and vouchers).

My Voucher Tab has a Button (Generate) which will randomly generate a voucher PIN and is supposed to open a rad window after all the code has been executed which it fails to do.

Just as a Test i dropped a button on the page (Outside of the Panel) and was able to successfully open the rad window with that button, but the RadWindow does not open if i try open it from the Generate Button held inside of the MultiPageView Control.

Any Ideas Why?

aspx code for my Panel

<telerik:RadAjaxPanel ID="RadAjaxPanel1" runat="server" BorderColor="Gray">

<telerik:RadTabStrip runat="server" ID="RadTabStrip1" SelectedIndex="0"

C# code for the Generate Button inside the PageView control

protected void btnVoucherGenerate_Click(object sender, EventArgs e)

{

if (tbGeneratePIN.Text == string.Empty)

{

lblVoucherPIN.ForeColor = System.Drawing.Color.Red;

lblVoucherPIN.Text = "Please insert voucher amount";

}

else

{

iThNkContext.Prepaid pre = new iThNkContext.Prepaid();

String newID = "";

newID = Guid.NewGuid().ToString().Replace("-", "");

newID = newID.Substring(newID.Length - 16);

newID = newID.ToUpper();

// Add PIN to Prepaid DB

var userInfo = (from c in db.Currencies

from a in db.Accounts

from s in db.Sites

from u in db.Users

where c.CurrencyID == a.CurrencyID &&

a.AccountID == u.AccountID &&

s.SiteID == u.SiteID &&

u.UserID == LoggedUserID)

select new

{

AccountID = a.AccountID,

CurrencyID = c.CurrencyID,

CurrencySymbol = c.CurrencySymbol,

SiteName = s.SiteName,

AccountName = a.AccountName

}).FirstOrDefault();

if (userInfo != null)

{

AccountID = userInfo.AccountID;

CurrencyID = userInfo.CurrencyID;

CurrencySymbol = userInfo.CurrencySymbol;

}

try

{

pre.CurrencyID = CurrencyID;

pre.AccountID = AccountID;

pre.Amount = Convert.ToDecimal(tbGeneratePIN.Text);

pre.SerialNumber = ("_");

pre.Pin = newID;

pre.TransactionTypeID = 2;

pre.SalesUserID = LoggedUserID);

pre.SalesDate = DateTime.Now;

pre.IsActivated = true;

pre.IsActive = true;

db.Prepaids.InsertOnSubmit(pre);

db.SubmitChanges();

pre.SerialNumber = Convert.ToString(pre.PrepaidID).PadLeft(9, '0');

db.SubmitChanges();

Amount = pre.Amount;

SerialNumber = pre.SerialNumber;

PinNumber = pre.Pin;

SiteName = userInfo.SiteName;

accountID = userInfo.AccountID;

AccountName = userInfo.AccountName;

// update the database and set isPrinted = 1

pre.IsPrinted = true;

db.SubmitChanges();

tbGeneratePIN.Text = string.Empty;

RadWindow newWindow = new RadWindow();

newWindow.NavigateUrl = "Vouchers.aspx";

newWindow.Top = Unit.Pixel(22);

newWindow.VisibleOnPageLoad = true;

newWindow.Left = Unit.Pixel(0);

RadWindowManager1.Windows.Add(newWindow);

}

catch (Exception ex)

{

lblVoucherPIN.ForeColor = System.Drawing.Color.Red;

lblVoucherPIN.Text = ex.Message;

}

Code i am using to open the RadWindow on the button outside of the PageView (This code works only if it is not inside of the PageView)

protected void RadButton1_Click(object sender, EventArgs e)

{

RadWindow newWindow = new RadWindow();

newWindow.NavigateUrl = "http://www.google.com";

newWindow.Top = Unit.Pixel(22);

newWindow.VisibleOnPageLoad = true;

newWindow.Left = Unit.Pixel(0);

RadWindowManager1.Windows.Add(newWindow);

}

Thanx in advance

Hello,

I see you add a newly generated RadWindow to the Windows collection of a RadWindowManager. This manager, however, is not in the RadAjaxPanel, so it is not updated in the browser, which means that the new RadWindow is not transferred to the client.

What I would advise:
- use the approach from this sticky thread to open the RadWindow: http://www.telerik.com/community/forums/aspnet-ajax/window/opening-radwindow-from-the-server.aspx. You can declare it in the RadWIndowManager Windows collection in the markup. You can additionally use its Client-side API to modify it in the function that will open it. This help article will show you other ways to open a RadWindow with JavaScript if you do not want to have it in the markup: http://www.telerik.com/help/aspnet-ajax/window-programming-opening.html. You will see how the RadWIndowManager can create RadWIndows on the fly

- if that is not a viable option for you, you can simply add the RadWindow to a placeholder inside the RadAjaxPanel. Note that, in this case, you would need to treat it like any other dynamic ASP contorl - recreating it after a postback will be needed. The RadWindowManager otherwise stores its Windows collection in the ViewState. I would still advise on opening it with a script registration, however, instead of using the VisibleOnPageLoad property.
